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.

- Set knob 22 to the OFF position. The boiler then produces only hot water.
Setting to pilot
- Set knobs 21 and 22 to the OFF position, leaving button 20 (fig. 20) lit. The function remains active unless the boiler freezes.
Turn off the boiler completely
- press push button 20 and the light goes out
- turn off the electricity supply to the boiler heater.
- shut off the gas supply by turning tap 33 (fig. 21)
Note:
In certain cases of installation it is possible that, after reheating the tank (system plus), the pipes (and possibly a radiator) may
heat up slightly. To prevent this, simply close heating inlet tap 31 (fig. 21).
Remember to re-open it at the start of the heating season, when you switch the heating back on by pressing button 22 (fig. 20)

15. Maintenance
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.
16. Overflow safety device
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.
17. Warranty
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.
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.
