If water freezing in the installation is suspected, check whether safety
piping is not blocked. The water added to the water charge in the
installation shall return through the overflow pipe from the pressure
vessel. If safety piping is blocked, the boiler must not be ignited, and
if it has been operating, proceed as in boiler emergency shutdown
procedure (see section 3.6.)
It is forbidden to:
- spill water onto the grate
- ignite the boiler using flammable liquids
After the end of the heating season (April to September), pay special
attention when using the boiler for heating the household hot water
only. Boiler power will be too high relative to the absorption capacity
of the boiler, therefore it will be necessary to charge less fuel than
during normal burning in winter season and to monitor the
thermometer.
If the temperature rises above 80˚C, it will be necessary to open the
shutoff valve and let the hot water flow into the central heating installation,
close the chimney damper (start the blower). If possible, open hot water taps in
the home (e.g. in bathtub) and drain the hot water.
Each Moderator boiler has a stub pipe for safety valve installation. The
valve must be unconditionally installed. Additionally the manufacturer
recommends installation of a thermal protection (in case of a closed-loop
system, see section 2.7.2, this is mandatory), to protect the boiler against
pressure build-up. Keep in mind that the thermal protection may only operate,
when the pressure in the installation is equal or greater than 2.3 bar and a safety
valve is installed.
