Maintenance schedule
6
Eliminate all system or boiler leaks.
Continual fresh makeup water will
reduce boiler life. Minerals can build
up in sections, reducing heat transfer,
overheating heat exchanger, and causing
heat exchanger failure. Leaking water
may also cause severe property damage.
1. Inspect all water and gas piping and verify to be leak
free.
2. Look for signs of leaking lines and correct any problems
found.
3. Contact a qualified service technician if problem
persists.
Check all piping for leaks

Maintenance procedures
Boiler must be serviced and maintained
ƽ 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
ƽ 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 1A on
page 4 of this manual.
Check pressure/temperature gauge
1. Make sure the pressure reading on the boiler pressure/
temperature gauge does not exceed 24 psi (165.5 kPa).
Higher pressure may indicate a problem with the
expansion tank.
2. Contact a qualified service technician if problem
persists.
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. 2-1).
2. Remove the 2" PVC cap with the switch located at
the top of the trap (FIG. 2-1).
3. Fill with fresh water until the water begins to pour out of
the
drain.
4. Replace the cap. Press the cap onto the trap until the cap
makes contact with the drain.
5. Replace the retaining screw.
