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.
WARNING
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 System
1. While the unit is running, check the discharge
end of the condensate drain tubing. Ensure no
flue gas is leaking from the condensate drain
tubing or tee connection by holding your fingers
near the opening.
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 unit and
condensate line and refill the condensate trap if
problem persists regularly.
WARNING
Under some circumstances the PRESTIGE may not
produce enough condensate to keep the condensate
trap full of liquid.
amounts of flue gases can be emitted into the sur-
rounding area through the condensate drain line or
tee.
3. Ensure the condensate drain line is not blocked
by pouring water through the plug 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, con-
tact a qualified service technician to inspect and
clean the condensate line.
4. To fill the condensate drain assembly, if neces-
sary, remove the plug from the condensate
assembly. Slowly pour water into the trap
assembly until water appears at the end of the
drain line. Stop filling and replace plug.
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.
