Maintenance Procedures

Clean Condensate Drain Assembly

1. Loosen the slip ring nut from the conden-
sate drain assembly disconnecting the
assembly from the boiler.
2. Empty any water from the trap and drain
assembly. Flush with fresh water as neces-
sary to clean.
3. Check the drain piping from the condensate
drain assembly to the drain. Flush to clean
as necessary.
4. Reassemble the condensate drain assembly
onto the boiler by tightening the slip ring
nut with rubber seal onto the boiler. Hand
tight only.
5. Remove the fill plug on the condensate drain
assembly and fill with water. See Fig. 16 on
page 27.
6. Replace the fill plug on drain assembly.

Check Ventilation Air Openings

Verify that all ventilation openings to the
mechanical room or building are open and
unobstructed. Check the operation and wiring
of any automatic ventilation dampers.
Check and verify the vent discharge and the
combustion air intake are free of debris and
obstructions.

Inspect Vent and Combustion Air Piping

Visually inspect the venting system and com-
bustion air piping for blockage, deterioration
or leakage. Repair any deficiencies.
Verify that the combustion air inlet piping is
connected, sealed and properly supported.
WARNING
Failure to inspect the vent system and
combustion air inlet piping and to have
any conditions repaired, can result in
severe personal injury or death.

Check Boiler System

Verify all system components are correctly
installed and operating correctly.
Check the cold fill pressure for the system, typ-
ical cold water fill pressure is 12 psig.
Verify the system pressure, as the unit operates at
high temperature, to ensure the pressure does not
exceed 25 psig. Excessive pressure reading indi-
cates expansion tank sizing is incorrect or system
performance problems.
Inspect air vent and air separators in the sys-
tem. Remove the caps on automatic air vents
and briefly depress the valve stem to flush
vent. Replace the cap when completed. Ensure
vents do not leak, replace any leaking vents.
