CGa Series 3 Gas-Fired Water Boiler — Boiler Manual
Service & maintenance — annual start-up10b
❏ Inspect . . .
Reported problems
Inspect any problems reported by owner and correct
before proceeding.
Boiler area
1. Verify that boiler area is free of any combustible
materials
, gasoline and other flammable vapors
and liquids.
2. Verify that boiler area (and air intake) is free of any
of the
contaminants listed in Table 1 on page 9 of
this manual. If any of these are present in the boiler
intake air vicinity, they must be removed. If they
cannot be removed, install combustion air piping
to the boiler in accordance with national, provincial
or local codes.
Air openings
1. Verify that combustion and ventilation air open-
ings to the boiler room and/or building are open
and unobstructed. Check operation and wiring of
automatic combustion air dampers, if used.
2. Verify that boiler vent discharge and air intake are
clean and free of obstructions.
Flue gas vent system
1. Visually inspect entire flue gas venting system
for blockage, deterioration or leakage. Repair any
joints that show signs of leakage in accordance with
vent manufacturer’s instructions.
2. Verify that masonry chimneys are lined, lining is in
good condition, and there are not openings into the
chimney.
Failure to inspect for the above
conditions and have them repaired
can result in severe personal injury
or death.
Pilot and main burner flames
1. Visually inspect pilot burner and main burner
flames as directed under Section 6d, page 32 of this
manual.
Water piping
1. Check the boiler interior piping and all system pip-
ing for signs of leaks.
2. Repair any leaks before proceeding.
The boiler should be inspected and started annu-
ally
, at the beginning of the heating season, only
by a qualified service technician
. In addition,
the maintenance and care of the boiler designated
in Table 6, page 42, and explained on the follow-
ing pages must be performed to assure maximum
boiler efficiency and reliability. Failure to service
and maintain the boiler and system could result in
equipment failure.
Eliminate all system or boiler leaks. Continual
fresh makeup water will reduce boiler life. Minerals
can build up in sections, reducing heat transfer,
overheating cast iron, and causing section failure.
Leaking water may also cause severe property
damage.
Do not use petroleum-based cleaning or sealing
compounds
in boiler system. Severe damage to
boiler will occur, resulting in substantial property
damage.
Electrical shock hazard — Turn off power to
the boiler before any service operation
on the
boiler except as noted otherwise in this instruction
manual. Failure to turn off electrical power could
result in electrical shock, causing severe personal
injury or death.
