APPENDIX B - MAINTENANCE
A qualified and adequately trained technician must perform the
inspection as specified in these instructions before each heating
season and at regular intervals.
Servicing, inspection and adjustment must be done by a trained
technician in accordance with all applicable local, state and na-
tional codes. Improper servicing or adjustment of the boiler could
result in equipment damage, injury, and/or dangerous conditions.

Maintenance
Gas Leak Inspection
Inspect all gas piping and gas valve especially pressure inlet to
confirm there are no leaks.

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 a fire 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 qualified 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.
