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.
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
compounds
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
a. With boiler firing, hold a candle or match be-
low lower edge of draft hood "skirt." If flame
does not blow out, but burns undisturbed, the
vent system is working properly.

:

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
CGs boilers
and air intake are clean and free of obstructions.
Remove any debris on the air intake or flue exhaust
openings.
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
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.
• — limit control may be set too
steam boilers
high or there may be system problems.
• Immediately contact your qualified service
technician to inspect the boiler and system.
