GOLD CGi Gas-Fired Water Boiler — Boiler Manual
44
Part Number 550-110-710/0107
Air openings
1. Verify that combustion and ventilation air openings
to the boiler room and/or building are open and
unobstructed.
2. Verify that boiler vent discharge is
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.
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 Start-up, Section 7 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.
Boiler heating surfaces
1. Disconnect the vent pipe at the boiler inducer outlet
connection after turning off power to the boiler.
2. Use a bright light to inspect the flue pipe interior
and inducer interior.
3. Inspect the boiler vent outlet area and heating sur
-
faces by looking through the opening.
4. If the vent pipe or inducer interior show evidence
of soot, follow
Cleaning boiler heating surfaces
on page 47 to remove the flue collector and clean
the boiler if necessary after close inspection of boiler
heating surfaces. If there is evidence of rusty scale
deposits, check the water piping and control system
to make sure the boiler return water temperature is
properly maintained (per this manual).
5. Reconnect vent to inducer outlet and replace all
boiler components before returning to service.
6. Check inside and around boiler for evidence of any
leaks from the boiler. If found, locate source of leaks
and repair.
10b
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 8, page 43, and explained on the following
pages must be performed to assure maximum boiler
efficiency and reliability. Failure to service and main-
tain the boiler and system could result in equipment
failure.
Eliminate all system or boiler leaks. Continual
fresh makeup water will reduce boiler life. Miner-
als can build up in sections, reducing heat transfer,
overheating cast iron, and causing section failure.
Leaking water may also cause severe property dam-
age.
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.

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, isolate the boiler and provide
outside combustion air. See national, provincial or
local codes for further information.
