Air openings

1. Verify that combustion and ventilation air openings

to the boiler room and/or building are open and

unobstructed.

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qualiedservice technicianif problem

persists.

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.
