Maintenance procedures

Boiler must be serviced and maintained

WARNING

The boiler must be inspected and started
annually at the beginning of the heating
season by a qualified service technician. In
addition, the maintenance and care of the
boiler designated on page 5 of this manual
and explained on pages 6 through 8 must
be performed to assure maximum boiler
efficiency and reliability. Failure to service
and maintain the boiler and system could
result in equipment failure, causing
possible severe personal injury, death, or
substantial property damage.

NOTICE

The following information provides
detailed instructions for completing the
maintenance items listed in the
maintenance schedule on page 5.

In

addition to this maintenance, the boiler
must be serviced and started up at the
beginning of each heating season by a
qualified service technician.

Check boiler area

WARNING

To prevent potential of severe personal
injury, death, or substantial property
damage, eliminate all materials discussed
below from the boiler vicinity and the
vicinity of the boiler combustion air inlet.
If contaminants are found:

Remove products immediately from the
area.

If they have been there for an

extended period, call a qualified service
technician to inspect the boiler for possible
damage from acid corrosion.

If

products cannot be removed,

immediately call a qualified service
technician to re-pipe vent and air piping
and locate vent termination/air intake
away from contaminated areas.

1.

Combustible/flammable materials -- Do not store 
combustible materials, gasoline or any other flammable 
vapors or liquids near the boiler. Remove immediately if
found.

2.

Air contaminants -- Products containing chlorine or 
fluorine, if allowed to contaminate the boiler intake air,
will cause acidic condensate in the boiler. This will cause 
significant damage to the boiler if allowed to continue.

Read the list of potential materials listed in Table 1 on 
page 4 of this manual. If any of these products are in the 
room from which the boiler takes its combustion air, they 
must be removed immediately or the boiler combustion 
air (and vent termination) must be relocated to another 
area.

Check pressure/temperature gauge

1.

Make sure the pressure reading on the boiler pressure/ 
temperature gauge does not exceed 24 psi.

Higher 

pressure may indicate a problem with the expansion 
tank.

2.

Contact a qualified service technician if problem persists.

Check vent piping

1.

Visually inspect the flue gas vent piping for any signs of
blockage, leakage, or deterioration of the piping. Notify 
your qualified service technician at once if you find any 
problems.

WARNING

Failure to inspect the vent system as noted
above and have it repaired by a qualified
service technician can result in vent system
failure, causing severe personal injury or
death.

Check air piping

1.

Visually inspect the air inlet elbow to be sure it is 
unobstructed. Inspect the entire length of air piping to 
ensure piping is intact and all joints are properly sealed.

2.

Call your qualified service technician if you notice any 
problems.

Check 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 expansion tank may 
not be working properly.

Immediately contact your 

qualified service technician to inspect the boiler and 
system.

Check condensate drain system

1.

Inspect the condensate drain line, condensate PVC 
fittings and condensate trap.

Fill condensate trap with water

1.

Remove the PVC cap retaining screw from the PVC cap
(FIG. 1).

2.

Remove the 2" PVC cap with the switch located at the top 
of the trap (FIG. 1).
