❏ Check daily . . . . . . . . . . . . . . . . .
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.
Pressure/temperature gauge
or pressure gauge (steam)
1. Water boilers — Make sure the pressure reading on
the boiler pressure/temperature gauge does not ex-
ceed 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 per-
sists.
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.
Boiler piping
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.
1. Visually inspect for leaks around piping, circulators,
relief valve and other fittings. Immediately call a
qualified service technician to repair any leaks.
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 below
lower edge of draft hood “skirt.” If flame does
not blow out, but burns undisturbed, the vent
system is working properly.
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.
❏ Check monthly . . . . . . . . . . . . . . . .
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.
