81 GENERAL CLEANING
WATER LEVEL
Regularly check the level of water in the system and top up if
required, taking care that cold water is not added suddenly into
the boiler when it is hot.
This operation should be required only a few times in each
heating season, with very low quantities of water. Otherwise,
look for the leak and repair it.
CLEANING THE CASING MATERIAL
Use a soapy solution and a sponge only. Rinse with clean water
and dry with chamois leather or a soft cloth.
PRECAUTIONS REQUIRED IN THE CASE OF LONG
BOILER STOPS
(one or several years)
The boiler and the chimney must be swept carefully. Close all
the doors of the boiler to prevent air from circulating inside the
boiler.
We advise removing the pipe which connects the boiler to the
chimney and to close off the nozzle with a cover.
PRECAUTIONS REQUIRED IF THE HEATING IS
STOPPED WHEN THERE IS A RISK OF FREEZING
We recommend the use of a correctly dosed antifreeze agent
to prevent to the heating circuit from freezing. If this cannot be
done, drain the system completely.
82 BURNER MAINTENANCE
Refer to the instructions supplied with the burner.
83 SYSTEM MAINTENANCE
DRAINING
We advise you against draining the system unless it is absolutely
necessary.
