DANGER: To verify the gas leaks use a soap solution or a gas
leak detector. Do not use methods that can cause explosions!
CHECK EXHAUST AND COMBUSTION AIR PIPE SYSTEM
Clear vent systems of any obstructions, corrosion, physical dam-
age, 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.

CHECKING FOR WIRING AND CONNECTIONS
Check that all wiring is securely fastened and in good condition
without any cracking or alteration of isolation or presence of cor-
rosion in metallic connection.
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 qualied
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 (green: part number 7738004985) for damage.
It is a must to replace the burner gasket when servicing and re-
quired if there is any signs of wear, deformity or discoloration of
the gasket and in any case not later than every two years.
