5.1 TYPE OF COAXIAL OUTLET (C12, C32, C42) xx
The boiler should only be installed with a fresh air inlet and smoke outlet device supplied by the boiler manufacturer. The kits are supplied separately from the boiler to meet the requirements of various types of installation. For more information about inlet/outlet accessories, refer to the accessories catalogue and the installation instructions inside the kits. The boiler is pre-equipped for connection to coaxial or twin flow air intake and burnt gas outlet systems.
Warning
The exhaust gas ducts should not be in contact with or close to inflammable material and should not pass through building structures or walls made of inflammable material. When replacing an old appliance, the gas intake and exhaust duct system will also have to be changed.
Important
Ensure that the gas intake and exhaust passages are not blocked. Ensure that the exhaust gas ducts do not have leaks.
5.2 TWIN FLOW FLUE TYPE (C12, C32, C42, C52, C82) xy
There is also the possibility of using an exhaust gas duct with separate tubes by using an adaptor on the outlet header and by inserting the tube in the air intake envisaged for this purpose. In order to use the air intake, you should:
1) Take the air intake cover off
2) Assemble the flange on the header supplied with the boiler
3) Assemble the membrane, if necessary, on the tube or the elbow
4) Insert the header on the tube or the elbow up until the lower stop (you do not have to use the washer).
5) Insert the elbow/header in the boiler air intake hole and fasten it with screws.
If the two elbows or in the same lateral direction and if you need to reduce the required space, the minimum 230 mm measurement can be reduced by carefully cutting the elbow below the air inlet by 25 mm.

In the special case where the connection is with separate tubes and with the boiler installed at a minimum distance of 6 cm from the wall, make a 10 cm ø hole, thus enabling better assembly between the fresh air elbow and the tube outside the wall (see diagram).
L = total length of air intake and burnt gas exhaust ducts. If the burnt gas flue length is over 5.5 m, install a condensate trap.
The maximum development value L, mentioned in the table includes the exhaust gas/fresh air terminal and for the coaxial system also takes into account an elbow. The C52 outlets should respect the following instructions: 1- Keep the same 80 mm ø for the gas intakes and exhaust gas ducts. 2- If you need to insert elbows in the gas intake and exhaust gas ducts, you should consider for each one the equivalent length to be included in the calculation of developed length. 3- The exhaust gas duct should jut above the roof by at least 0.5 m. 4- The intake and exhaust gas ducts in C52 cannot be installed on opposite walls of the building.
Diagrams illustrating some typical coaxial and twin flow installations. For more detailed information concerning exhaust gas ducts and fresh air intakes, consult our accessory catalogues.
Warning
If the selected exhaust gas duct is planned to be fitted with a restrictor as indicated in the corresponding tables, then the installation of the restrictor is compulsory.

This boiler is equipped with a flue gas extraction flow detection system which authorises operation of the burner. If the flow is insufficient for a prolonged period of time, the boiler shuts down for safety reasons and indicator lights (23) 40, 60 and 80 flash. Warning: this flue gas checking device must not be disconnected or have unwarranted work carried out on it.If it needs to be replaced, only original parts may be used.
Your boiler is under warranty. The warranty certificate specifies the warranty conditions: check that the detachable section of this certificate has been returned to Chaffoteaux & Maury.
A qualified professional must have installed, adjusted and commissioned your installation if you wish to take advantage of the warranty. This assures you that the fitter complied with the installation manual and that regulatory and safety conditions have been met.
Your first boiler technical inspection will be carried out free of charge at your request by a qualified Chaffoteaux & Maury tech­nical station professional.
Current legislation requires a mandatory annual service of your water heater.
Once a year, have it checked by a qualified professional.
Annual service contract formats may be suggested to you by service providers for all boiler servicing. Contact your gas fitter or our commercial services.
The manufacturer's warranty, which covers manufacturing faults, should not be confused with servicing operations.

18. Practical advice
• Pump degumming system
With the boiler switched on (indicator light 20 lit), the circulating pump operates for 1 minute after it has been stopped for longer than 23 hours, irrespective of the boiler's operating mode, to prevent the pump from sticking.
Precautions to take in freezing conditions
We recommend that you contact your gas fitter or After-Sales service, who will advise you of the measures to take according to your circumstances.
• Domestic hot water circuit
(system plus)
The hot water circuit is drained after closing the appliance's water counter and cold water tap:
- open a hot water tap
- Drain the tank
• Heating circuit
Take one of the following steps:
- 1) drain the circuit of the heating appliance
- 2) protect the heating installation with an antifreeze product. Periodically checking the level of protection provided by this antifreeze is an additional warranty requirement.
- 3) allow your installation to run at low load by setting the room thermostat to the antifreeze position (between 5 and 10°C).
- 4) leave the power to the boiler on. It is fitted with an antifreeze device which activates the circulation pump, then the burner.
