Again once a year call your authorized service for checking the combustion
parameters, security and operational devices.
When the burner lock-out for any reason please check the following;
Reset the burner fault maximum 3 times and still not firing call your authorized
service.
In closed expansion systems with a membrane type expansion tank, tank gas
pressure must be controlled regularly by a qualified service. If the pre-charge gas
pressure is less then specified; then the system pressure will rise enormously
and can cause an explosion.
If there is a fuel, flue gas or water leakage in the system, stop the burner and
call the responsible authority.
If the flue gas seals in any part of the boiler and flue gas exhaust is not
functioning properly and there is a flue gas leakage stop the burner and please
call an authorized service for repair or replacement.
Check the make up water analysis periodically to avoid the formation of scale
and corrosion which initially reduces the system efficiency and in long term will
permanently damage the boiler.
Periodically check the safety and operational equipments.
During the long shut off periods run the circulation pump(s) and anti-
condensation pump 5 min/month in order to avoid pump shaft lock-out.
Frequent make up water need should be non existent it is a symptom of
leakage which should be repaired as soon as possible.
