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. 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 (165.5 kPa).
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.
ƽ 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, vent line, condensate
PVC fittings, and condensate trap.
Flush condensate trap with water
1. Remove the four (4) screws securing the top cover to the
condensate trap and remove the cover (FIG. 2-1).
2. Locate the plastic ball inside the float tube. Verify there
is nothing under the ball causing it to not seat properly.
3. Fill with fresh water until the water begins to pour out of
the drain.
4. Replace the top cover and the screws removed in Step 1.
