Pressure/temperature gauge or pressure gauge (steam)

1.Water boilers — Make sure the pressure reading on the boiler pressure/temperature gauge does not exceed 24 psig. Higher pressure may indicate a problem with the expansion tank or gauge.

2.Steam boilers — Make sure the pressure reading on the boiler pressure gauge does not exceed 15 psig. Higher pressure indicates a problem with the gauge or limit control.

3.Contact a qualified service technician if problem persists.

Air openings

1.Verify that combustion and ventilation air openings to the boiler room and/or building are open and unobstructed.

2.CGs boilers — Verify that boiler vent discharge and air intake are clean and free of obstructions. Remove any debris on the air intake or flue exhaust openings.

❏Check monthly . . . . . . . . . . . . . . . .

Boiler piping

1.Visually inspect for leaks around piping, circulators, relief valve and other fittings. Immediately call a qualified service technician to repair any leaks.

Have leaks fixed at once by a qualified service technician. Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating cast iron, and causing section failure.

Do not use petroleum-based cleaning or sealing compounds in boiler system. Severe damage to boiler and system components can occur, resulting in possible severe personal injury, death or substantial property damage.

Venting system

Failure to inspect the vent system as noted above and have them repaired by a qualified service technician can result in vent system failure, causing severe personal injury or death.

1.Visually inspect all parts or the flue gas venting system for any signs of blockage, leakage or joints or deterioration of the piping.

2.CGa and EG boilers:

If flame blows out or flickers severely, the vent system must be checked for obstructions or other causes of improper venting.

b.Verify the vent damper (CGa and EG boilers) opens before burners ignite.

3.Notify your qualified service technician at once if you find any problem.

Boiler relief valve . . . . . . . . .

1.Inspect the boiler relief valve (see Figure 3) and the relief valve discharge pipe for signs of weeping or leakage.

2.If the relief valve often weeps:

•water boilers — the expansion tank may not be working properly.

•steam boilers — limit control may be set too high or there may be system problems.

•Immediately contact your qualified service technician to inspect the boiler and system.
