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 for the warranty to be valid. 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 tech-
nical station professional.
• 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.
