What are the dimensions of the Ideal Boilers Atlantic 24 model?

The boiler casing dimensions for the Ideal Boilers Atlantic 24 variant include: Height - 700mm, Width - 395mm, Depth - 285mm. Refer to Section 2.18 Wall Mounting Template of this manual for precise measurements and layout.

What should I do if the boiler displays error code 'F7'?

Error code 'F7' indicates low mains voltage, which may prevent proper operation of the boiler. Check and ensure a stable electrical supply with sufficient voltage; contact a professional technician for further diagnosis or repairs.

How do I drain the boiler before servicing?

Drain the boiler by loosening the bottom valve located below the heating exchanger, allowing water to flow out until the boiler is drained. Follow safety and operational guidelines for draining as described in Section 3.21 of this manual.

How do I factory reset the boiler settings?

To perform a factory reset on your Ideal Boilers Atlantic 24, press the 'Reset' button located on the control panel for approximately 10 seconds until the LED indicates ready mode. This will revert all current configurations to their default state.

How do I connect the flue system?

To connect the flue, position it correctly through the wall hole and install external seals like black rubber seals around the connection area. Ensure proper fitting as described in Section 2.12 to prevent any leakage issues.

How do I maintain the heat exchanger?

Maintain the heat exchanger by cleaning it regularly and checking for signs of corrosion or damage annually. Follow instructions in Section 3.6 Cleaning The Heat Exchanger to ensure optimal performance.

What are the safety warnings concerning boiler location?

The Atlantic combi must be installed on a flat and vertical internal wall capable of supporting its weight safely without obstruction from combustible materials. It must also maintain proper clearance for servicing as outlined in Section 1.7.

What are the system requirements for central heating?

Ensure your central heating system complies with flow temperatures up to 84 °C and working pressures up to 3 bar. Use components suitable for these conditions, check valve settings regularly, and adhere to guidance provided in Section 1.16 of this manual.

########### 1 GENERAL

############# 1.1 INTRODUCTION

The Atlantic combi range of boilers are wall mounted, full sequence, automatic spark ignition, low water content, fanned flue, high efficiency, condensing, combination gas boilers. Note. Due to the high efficiency of the boiler a plume of water vapour will form at the terminal during operation. Central heating (CH) output is fully modulating with a range of:

24 4.8 to 24.2kW 30 6.1 to 24.2kW 35 7.1 to 24.2kW

Instantaneous domestic hot water (DHW) output is also fully modulating with a maximum of :

24 24.2kW 30 30.3kW 35 35.3kW

The boiler is supplied fully assembled with DHW plate heat exchanger, diverter valve, circulating pump, pressure gauge, safety valve and CH expansion vessel.

Variable CH and DHW temperature controls are fitted on the user control and the boiler features a DHW preheat facility.

The boiler includes as standard:

Page 15

When thermostatic radiator valves are used, the space heating temperature control over a living / dining area or hallway having a heating requirement of at least 10% of the minimum boiler heat output should be achieved using a room thermostat, whilst other rooms are individually controlled by thermostatic radiator valves. However, if the system employs thermostatic radiator valves on all radiators, or two port valves, then a bypass circuit must be fitted with an automatic bypass valve to ensure a flow of water should all valves be in the closed position.

############# 1.13 ELECTRICAL SUPPLY

WARNING. This appliance must be earthed. Wiring external to the appliance MUST be in accordance with the current I.E.E. (BS.7671) Wiring Regulations and any local regulations which apply. For IE reference should be made to the current ETCI rules for electrical installations.

The mains supply to the boiler and system wiring centre shall be through one common fused double pole isolator and for new heating systems, and where practical replacement boiler installations, the isolator shall be situated adjacent to the appliance.

############# 1.14 CONDENSATE DRAINRefer to Sections 2.17 & 3.5

A condensate drain is provided on the boiler. This drain must be connected to a drainage point on site. All pipework and fittings in the condensate drainage system MUST be made of plastic - no other materials may be used.

IMPORTANT. Any external runs must be in accordance with BS 6798. The drain outlet on the boiler is sized for standard 21.5mm overflow pipe. It is a universal fitting to allow use of different brands of pipework.

WALL

1.15 BOILER DIMENSIONS, SERVICES & CLEARANCES

The boiler connections are made on the boiler bulkhead fittings. Refer to Section 2.18.

The following minimum clearances must be maintained for operation and servicing.

Additional space will be required for installation, depending upon site conditions.

Side and Rear Flue

a. Provided that the flue hole is cut accurately, e.g. with a core drill, the flue can be installed from inside the building where wall thicknesses do not exceed 600mm. Where the space into which the boiler is going to be installed is less than the length of flue required the flue must be fitted from the outside.

Installation from inside ONLY

b. If a core boring tool is to be used inside the building the space in which the boiler is to be installed must be at least wide enough to accommodate the tool.

![image 1](ATLANTIC_20COMBI_20INSTALL_20GUIDE_images/imageFile1.png)

Front clearance

The minimum front clearance when built in to a cupboard is 5mm from the cupboard door but 450mm overall clearance is still required, with the cupboard door open, to allow for servicing.

* Bottom clearance

Bottom clearance after installation can be reduced to 5mm.

This must be obtained with an easily removable panel to provide the 100mm clearance required for servicing.| |---|

|General

1. The installation must comply with all relevant national and local regulations.
2. The installation should be designed to work with flow temperatures of up to 84 oC.
3. All components of the system must be suitable for a working pressure of 3 bar and temperature of 110 oC. Extra care should be taken in making all connections so that the risk of leakage is minimised.

The following components are incorporated within the appliance:

a. Circulating pump.
b. Safety valve, with a non-adjustable preset lift pressure of 3 bar.
c. Pressure gauge, covering a range of 0 to 4 bar.
d. An 8-litre expansion vessel, with an initial charge pressure of 0.75 bar.

4. ‘Make-up’ Water. Provision must be made for replacing water loss from the system, either :

a. From a manually filled ‘make-up’ vessel with a readily visible water level. The vessel should be mounted at least 150mm above the highest point of the system and be connected through a non-return valve to the system, fitted at least 150mm below the ‘make-up’ vessel on the return side of the radiators. or
b. Where access to a ‘make-up’ vessel would be difficult, by pre-pressurisation of the system.

The maximum cold water capacity of the system should not exceed 143 litres, if not pressurized. However, if the system is to be pressurized, the efficiency of the expansion vessel will be reduced and a larger vessel (or smaller system volume) may be necessary. If the capacity of the vessel is not considered sufficient for this, or for any other reason, an additional vessel MUST be installed on the return to the boiler.

Guidance on vessel sizing is given in table above.

5. Filling The system may be filled by the following method:

Where the mains pressure is excessive a pressure reducing valve must be used to facilitate filling.

a. Thoroughly flush out the whole system with cold water.
b. Fill and vent the system until the pressure gauge registers 1bar and examine for leaks.
c. Check the operation of the safety valve by raising the water pressure until the valve lifts. This should occur within 0.3bar of the preset lift pressure.
d. Release water from the system until the minimum system design pressure is reached; 1.0 bar if the system is to be pre-pressurised.

Notes

a. The method of filling, refilling, topping up or flushing sealed primary hot water circuits from the mains via a temporary hose connection is only allowed if acceptable to the local water authority.
b. Antifreeze fluid, corrosion and scale inhibitor fluids suitable for use with boilers having aluminium heat exchangers may be used in the central heating system.

|........ SYSTEM REQUIREMENTS - CONT Domestic Hot Water

1. The DHW service must be in accordance with BS.5546 & BS.6700.
2. Refer to Table 1 for minimum and maximum working pressures. In areas of low mains water pressures the domestic hot water regulator may be removed from the DHW flow turbine cartridge. Refer to Section 3.20. The boiler will require the flow rate to be set to obtain a temperature rise of 35oC at the tap furthest from the boiler.
3. The boilers are suitable for connection to most types of washing machine and dishwasher appliances.
4. If the shower/mixer valve does not incorporate non-return valves the following must be followed: a. The cold inlet to the boiler is fitted with an approved anti-

vacuum or syphon non-return valve.

b. Hot and cold water supplies to the shower are of equal

pressure. 5. Hard Water Areas Where the water hardness exceeds 200mg/litre (200 ppm), it is recommended that a proprietary scale reducing device is fitted into the boiler cold supply within the requirements of the local water company.

IMPORTANT. Provision must be made to accommodate the expansion of DHW contained within the appliance. If the DHW inlet contains a back flow prevention device or non-return valve, e.g. a water meter, then a mini expansion vessel should be fitted between the device and the boiler in the cold inlet pipe.

Cold water, rising main and pipework in exposed areas need to be suitably lagged to prevent freezing.| |---|

|The boiler does not normally need a bypass but at least some radiators on the heating circuit, of load of at least 10% of the minimum boiler output, must be provided with twin lockshield valves so that this minimum heating load is always available. See note regarding thermostatic radiator valves on page 13.

Note. Systems incorporating zone valves which could completely cut off the flow through the system must also include a bypass.

BALANCING

1. Set the programmer to ON. Close the manual or thermostatic

valves on all radiators, leaving the twin lockshield valves (on

the radiators referred to above) in the OPEN position. Turn up the room thermostat and adjust the lockshield valve to give an uninterrupted flow through the radiator. These valves should now be left as set.

2. Open all manual or thermostatic radiator valves and adjust the lockshield valves on the remaining radiators, to give around 20oC temperature drop at each radiator.

|CENTRAL HEATING

The Atlantic combi range of boilers have an ALUMINIUM alloy heat exchanger.

IMPORTANT. The application of any other treatment to this product may render the guarantee of Ideal Heating Invalid. Ideal Heating recommend Water Treatment in accordance with the Benchmark Guidance Notes on Water Treatment in Central Heating Systems.

If water treatment is used Ideal Heating recommend only the use of SCALEMASTER SM-1 PRO, FERNOX, MBI, ADEY MC1, SENTINEL X100 or CALMAG CM100 inhibitors and associated water treatment products, which must be used in accordance with the manufacturers’ instructions.

DOMESTIC HOT WATER In hard water areas where mains water can exceed 200ppm Total Hardness (as defined by BS 7593 Table

2) a scale reducing device should be fitted into the boiler cold supply within the requirements of the local water company. Ideal Heating recommend the use of Fernox Quantomat, Sentinel Combiguard, Calmag CalPhos I scale reducing devices or Scalemaster In-line Scale Inhibitor branded Ideal, which must be used in accordance with the manufacturers’ instructions.

This boiler can be used with a water softener. However, the heating system should not be filled with softened water as any softening chemicals could enhance corrosion of certain materials in the heating system, including aluminium and steel. The heating system should always be filled from the bypass on the water softener installation.

The mains cold water feed can come from a water softener as the materials used in the domestic hot water circuit are fully resistant to any chemicals in softened water.

Notes.

1. It is most important that the correct concentration of the water treatment products is maintained in accordance with the manufacturers’ instructions.
2. If the boiler is installed in an existing system any unsuitable additives MUST be removed by thorough cleansing. BS 7593 details the steps necessary to clean a domestic heating system.
3. In hard water areas, treatment to prevent lime scale may be necessary.
4. Under no circumstances should the boiler be fired before the system has been thoroughly flushed.

|2.9 DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED IMPORTANT. The boiler must be installed in a vertical position in accordance to the installation instructions.

FLUE KITS Telescopic Flue‘B’ Pack - contains: Flue turret, telescopic flue incorporating a terminal and rubber wall seals.

Horizontal Flue Terminal (600mm long) ‘B’ Pack - contains: Flue turret, non telescopic single piece flue incorporating a terminal and rubber wall seals.

Horizontal Flue Terminal (1000mm long) ‘B’ Pack - Flue turret, telescopic flue incorporating a terminal, rubber wall seals and instructions.

Note. If ‘B’ packs are used on their own (either 1 piece or telescopic), then they can be fitted horizontally as the flue inside is designed to slope 1.5 degrees.

Flue Kit 203129 - D Pack Flue Extension 100mm DIA 1000mm long

Flue Kit 211037 - D Pack Flue Extension 100mm DIA 500mm long
Flue Kit 211038 - D Pack Flue Extension 100mm Dia 2000mm long
Flue Kit 211039 - Roof Flue Kit with Vertical Connector

When extension ‘D’ Packs are used the flue duct must incline 1.5 degrees away from the appliance, to allow the condensate to drain back to the boiler and out of the condensate drain. It is recommended that a support bracket is fitted on every 1 metre of pipe work used

and the bracket is located as close to the collar as possible. The bracketing must ensure a 1.5 degree fall back to the appliance.

Optional Flue Finishing Kit - UIN 155988 & Concentric Flue Screw Retaining Kit (Optional Kit of mechanical fixing of flue joints) Only use water as a lubricant during assembly. The ‘B’ pack terminal is classed as part of the maximum flue length. These flue systems incorporates a removable flue outlet nose that utilises a push fit location system. This enables the installation of deflector, high level or balcony flue kits without the removal of the whole ‘B’ pack terminal. The appliance must not be operated without the desired outlet nose correctly fitted in place, ensuring the side location dimples are in line with the mounting face allowing the correct sealing of the components. It is IMPORTANT that all attachments are fitted in accordance to the installation instructions provided with them.

The TURRET supplied in the ‘B’ Pack has an upper combustion sample point with a screw cap seal and a lower air sample point with an air stopper seal. Ensure all caps & seals are in place.

Additional Termination Kits available for use with these ‘B’ packs.

The discharge pipe should be positioned so that the discharge of water or steam cannot create a hazard to the occupants of the premises or damage the electrical components and wiring.

FILLING IMPORTANT - when filling:

A. Ensure the dust cap on air vent located at the rear of the pump chamber is slightly unscrewed.
B. When filling, there may be a slight water leak from the air vent therefore electrical connections should be protected.

CH -

1. Ensure that the CH isolating handles are open.
2. Fill and vent the system. Refer to Section 1.16 for setting pressure.

DHW -

1. Fully open all DHW taps and ensure that water flows freely from the.
2. Close all taps.

programmers. To do so follow the instructions below:

1. Swing the lower front panel down. Refer to Section 3.2.
2. Route cable through the grommet and cable clamp and tighten to provide cord anchorage.
3. Connect the live, neutral and earth wires to the terminal strip. When making the mains electrical connections to the boiler it is important that the wires are prepared in such a way that the earth conductor is longer than the current carrying conductors, such that if the cord anchorage should slip, the current carrying conductors become taut before the earthing conductor.
4. Swing the control box back up into the operating position and retain with the screws previously removed.

The boiler comes pre-fitted with a link wire between the room thermostat/Timer connections on the terminal strip. This creates a permanent call for heat and must be removed when adding a room thermostat.

ROOM THERMOSTAT - WIRING

1. Remove link wire between Room stat/timer terminals.
2. Connect room stat as shown in wiring diagram opposite.
3. If room stat has a neutral connection, connect this to terminal N (load) in the fused spur. FROST THERMOSTAT - WIRING

If parts of the system are vulnerable to freezing or the programmer is likely to be left off during cold weather a frost stat should be fitted in conjunction with a pipe thermostat.

1. Position the frost thermostat in a suitable position, i.e. area vulnerable to freezing.
2. Connect frost stat across terminals marked frost stat as shown in wiring diagram opposite. OPENTHERM - WIRING

1. Remove link wire and connect an Opentherm controller via the available terminals shown in the wiring diagram opposite. IMPORTANT: Do not connect 230v to these terminals or the boiler electronics will be damaged.|INSTALLATION| | |INSTALLATION| |Wiring External to the Boiler The fuse rating should be 3A. Wiring external to the boiler MUST be in accordance with the current I.E.E. (BS.7671) Wiring Regulations and any local regulations. Frost Protection

If parts of the pipework run outside the house or if the boiler will be left off for more than a day or so then a frost thermostat should be wired into the system.

The frost thermostat should be sited in a cold place but where it can sense heat from the system.

Note. If the boiler is installed in a garage it may be necessary to fit a pipe thermostat, preferably on the return pipework. Earths are not shown for clarity but must

never be omitted.

To instigate the boiler warranty the boiler needs to be registered with the manufacturer within one month of the installation. The warranty rests with the end-user (consumer), and they should be made aware it is ultimately their responsibility to register with the manufacturer, within the allotted time period.

It is essential that the boiler is serviced in line with the manufacturers’ recommendations, at least annually. This must be carried out by a competent Gas Safe registered engineer. The service details should be recorded on the Benchmark Service and Interim Boiler Work Record and left with the householder. Failure to comply with the manufacturers’ servicing instructions and requirements will invalidate the warranty.

www.hhic.co.uk

This Commissioning Checklist is to be completed in full by the competent person who commissioned the boiler as a means of demonstrating compliance with the appropriate Building Regulations and then handed to the customer to keep for future reference.

Failure to install and commission according to the manufacturers’ instructions and complete this Benchmark Commissioning Checklist will invalidate the warranty. This does not affect the customer’s statutory rights.

All installations in England and Wales must be notified to Local Authority Building Control (LABC) either directly or through a Competent Persons Scheme. A Building Regulations Compliance Certificate will then be issued to the customer.

########### 6 FLUE & INTEGRITY CHECKS

####### FLOWCHART FOR CO LEVEL AND COMBUSTION RATIO CHECK ON COMMISSIONING A CONDENSING BOILER

Important Preliminary Information on Checks The air gas ratio valve is factory-set and must not be adjusted DURING COMMISSIONING. If the boiler requires conversion to operate with a different gas family (e.g. conversion from natural gas to LPG) separate guidance is provided with the conversion kit supplied and this must be followed.

################## PRIOR TO CO LEVEL AND COMBUSTION RATIO CHECK

The installation instructions must have been followed, gas type verified and gas supply pressure / gas rate checked as required prior to commissioning.

As part of the installation process, ESPECIALLY WHERE A FLUE HAS BEEN FITTED BY PERSONS OTHER THAN THE BOILER INSTALLER, visually check the integrity of the whole flue system to confirm that all components are correctly assembled, fixed and supported. Check that maximum flue lengths have not been exceeded and all guidance has been followed (e.g. Gas Safe Register Technical Bulletin (TB) 008 where chimney/flues are in voids).

The ECGA should be of the correct type, as specified by BS 7967. Prior to its use, the ECGA should have been maintained and calibrated as specified by the manufacturer. The installer must have the relevant competence for use of the analyser. Check and zero the analyser IN FRESH AIR in accordance with the analyser manufacturer’s instructions.

KEY: CO = carbon monoxide CO2 = carbon dioxide O2 = oxygen Combustion Ratio = The CO reading measured in ppm divided by the CO2 reading first converted to ppm ppm = parts per million GS(I&U)R = Gas Safety (Installation and Use) Regulations

IMPORTANT: Ensure boiler is in normal operation with a heat demand before setting Maximum / Minimum rate function.

|*Setting to Maximum Rate (DHW max. gas rate, operating in CH mode):

1. Hold “preheat” & “restart” buttons together for more than 5s
2. Last 3 faults will be shown
3. SH shown, press “restart”
4. Burner will run for 10 minutes at maximum rate.
5. Press “restart” to exit Maximum Rate mode.

69Installation and Servicing

Start

|Carry Out Flue Integrity Check Using Analyser Insert analyser probe into air inlet test point (where available) and allow readings to stabilise.

Note. Where no air inlet test point is provided then a flue integrity check with the analyser is not possible. The installer should verify that flue integrity has been visually checked in accordance with the “Prior to CO level and combustion ratio check” (see opposite page) before proceeding to the “check CO level and combustion ratio at maximum rate” stage below.|Carry Out Flue Integrity Check Using Analyser Insert analyser probe into air inlet test point (where available) and allow readings to stabilise.
