leak detector. Do not use matches, candles, or other methods
that can cause a re or explosion!
CHECK EXHAUST AND COMBUSTION AIR PIPE SYSTEM
Clear vent systems of any obstructions, corrosion, physical dam-
age, water stains and rust. Verify the connection between the in-
dividual components.
Verify the outside terminations are clear. Clean the screens and the
louvers if there is any debris.
INSPECTION OF IGNITION ELECTRODE AND IONIZATION ELECTRODE
Verify that the electrode is clean of deposits and use an emery
cloth or other material to remove deposits as required.

CHECK WIRING AND CONNECTIONS
Check that all wiring is securely fastened and in good condition
without any cracking or alteration of isolation or presence of the
insulation or corrosion on the metallic contacts.
BURNER GASKET INSPECTION
To ensure the reliability of the boiler/system, the boiler must be
maintained as outlined in this manual and a qualied service
technician must startup and service it at least annually.
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 (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 gas-
ket and in any case not later than every two years.
