GOLD CGs Gas-Fired Water Boiler — Boiler Manual

10b Service & maintenance — annual start-up

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 5, page 37,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.

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

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. When air is ducted to boiler, verify that air inlet hose is connected and properly sealed.

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 in this manual section 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 tempera- ture 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.
