Monthly Maintenance

3.3.1 Check Vent and Combustion Air Piping

• Visually inspect the venting system and combus-
tion air piping for blockage, deterioration of gas-
kets or leakage. Contact a qualified service techni-
cian immediately if any problems are found.
DANGER
Failure to inspect the vent system and com-
bustion air inlet piping and to have any con-
ditions repaired, will result in serious injury,
or death.

3.3.2 Check Pressure Relief Valve

1. Visually inspect the pressure relief valve and the
relief valve discharge pipe for signs of weeping or
leakage.
2. If the pressure relief valve weeps often, the expan-
sion tank may not be operating properly. Immedi-
ately contact a qualified service technician to in-
spect the unit and system.

3.3.3 Check Condensate Drain System

1. Ensure condensate drain assembly is firmly secured
to bottom of the unit. See Fig. 1 on the right.
WARNING
Do not operate the boiler without the fac-
tory-supplied condensate drain assembly
installed. Operation of the boiler without
the condensate drain assembly installed can
result in property damage, serious injury, or
death.
2. 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 by
holding your fingers near the opening.
3. If you notice flue gas leaking, turn off the unit and
contact a qualified service technician to inspect the
unit and condensate drain assembly.

4. Ensure the condensate drain tubing is not blocked
by pouring water through the fill plug port on the
condensate drain assembly. The water should flow
out of the end of the drain tubing. If water does
not appear at the end of the drain tubing, contact
a qualified service technician to inspect and clean
the condensate drain assembly.
5. To fill the condensate drain assembly, remove the
fill plug from the condensate assembly. Slowly pour
water into the assembly until water appears at the
end of the drain tubing. Stop filling and replace
plug.
