GOLD CGi Gas-Fired Water Boiler — Boiler Manual

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

. Verify that boiler vent discharge is

clean and free

of obstructions

Flue gas vent system

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

of this

manual.

Water piping

1. Check the boiler interior piping and all system pip-

ing for signs of leaks.

. 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.

. 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 4 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.

Boiler area
1. Verify that boiler area is free of any

combustible

materials

, gasoline and other flammable vapors

and liquids.

. 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
