BURNER GASKET INSPECTION
You must maintain the boiler as outlined in this manual and have
the boiler started up and serviced at least annually by a qualified
service technician to ensure boiler/system reliability.
This includes a combustion test and the cleaning of the combus-
tion chamber.
When disassembling the heat exchanger it is crucial to inspect the
Burner Gasket for damage.
It is a must to replace the burner gasket when servicing and if
there are any signs of wear, deformity or discoloration of the gas-
ket and in any case not later than every two years.
