DANGER: To verify the gas leaks use a soap solution or a gas
leak detector. Do not use matches, candles, or other methods
that can cause explosions!
CHECK EXHAUST AND COMBUSTION AIR PIPE SYSTEM
Clear vent systems of any obstructions, corrosion, physical
damage, water stains, rust. Verify the connection between the
single components.
Verify the outside terminations are clear. Clean the screens and the
louvers if there is any debris.
INSPECTION OF IGNITION ELECTRODE

CHECKING FOR WIRING AND CONNECTIONS
Check that all wiring is securely fastened and in good condition
without any cracking or alteration of the insulation or corrosion on
the metallic contacts.
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 combustion
chamber.
When disassembling the heat exchanger it is crucial to inspect the
Burner Gasket (part number 0CR105917) 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 gasket and
in any case not later than every two years.
