Monthly Maintenance
Check Vent Piping
1. Visually inspect the flue gas vent piping for any
signs of blockage, leakage or deterioration of
the piping. Notify a qualified service technician
immediately if any problems are found.
Failure to inspect the venting system as noted and
have it repaired by a qualified service technician can
result in the vent system failure, causing severe per-
sonal injury or death.
Check Combustion Air Inlet Piping
1. Visually inspect the combustion air inlet piping for
any signs of blockage. Inspect the entire length
of the combustion air inlet piping to ensure piping
is intact and all joints are properly sealed.
2. Notify a qualified service technician if any prob-
lems are found.
Check Pressure Relief Valve
1. Visually inspect the primary pressure relief valve
and the relief valve discharge pipe for signs of
weeping or leakage.
2. If the pressure relief valve often weeps, the
expansion tank may not be operating properly.
Immediately contact a qualified service techni-
cian to inspect the unit and system.
Check Vent Condensate Drain Assembly
1. While the appliance is operating, check the dis-
charge end of the condensate drain tubing.
Ensure no flue gas is leaking from the conden-
sate drain tubing by holding your fingers near
the termination.
2. If you notice flue gas leaking from the opening,
this indicates a dry condensate drain trap. Fill
the condensate trap assembly. Contact a quali-
fied service technician to inspect the appliance
and condensate line and refill the condensate
trap if problem persists regularly.
WARNING
Under some circumstances the CHALLENGER may
not produce enough condensate to keep the con-
densate trap full of liquid. If the trap is not full, small
amounts of flue gases can be emitted into the sur-
rounding area through the condensate drain line.
3. Ensure the condensate drain line is not blocked
by pouring water through the top open port on
the condensate drain assembly. The water
should flow out of the end of the drain line. If
water does not appear at the end of the drain
line, contact a qualified service technician to
inspect and clean the condensate line.
4. To fill the condensate drain assembly, slowly
pour water into the top of the trap assembly until
water appears at the end of the drain line. Stop
filling.
Check Automatic Air Vents (If Used)
1. Remove the cap “A” from any automatic air vent
in the system and check operation by depressing
valve “B” slightly with the tip of a screwdriver. See
Fig. 1.
2. If the air vent valve appears to be working freely
and not leaking, replace cap “A”, screwing it on
fully.
3. Loosen cap “A” one full turn to allow vent to
operate properly.
4. Have the air vent replaced by a qualified service
technician if it does not operate correctly.
