Check vent & air piping
1. Visually inspect the flue gas vent piping
and air piping for any signs of blockage,
leakage or deterioration of the piping.
Notify your qualified service technician
at once if you find any problem.
Failure to inspect the vent/air
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.
Check the relief valve
1. Inspect the boiler relief valve and the relief
valve discharge pipe for signs of weeping
or leakage.
2. If the relief valve often weeps, the expan-
sion tank may not be working properly.
Immediately contact your qualified ser-
vice technician to inspect the boiler and
system.
Check the condensate drain
system
1. Visually inspect the condensate drain
tubing and the end of the tube. Make sure
the tube is in good condition and that
condensate can run freely.
2. Inspect the boiler condensate trap, located
under the boiler (see Figure 3). Check for
any sediment and clean out if necessary.
Make sure the trap has water in it.
3. Contact a boiler service technician if you
observe any problems.

Check automatic air vents

2. Remove the cap from any automatic air
vent in the system and check operation
by depressing valve "B" slightly with the
tip of a screwdriver.
Scald hazard
air vent may be very hot. Avoid
contact to prevent possible se-
vere personal injury.
3. If the air vent valve appears to be work-
ing freely and not leaking, replace cap "A",
twisting all the way on.
4. Loosen cap "A" one turn to allow vent to
operate.
5. Have vent replaced if it does not operate
correctly.
