94
Annual startup (continued)
The boiler should be inspected and
started annually, at the beginning of
the heating season, only by a qualified
service technician. In addition, the
maintenance and care of the boiler
designated in Figure 105, page 92 and
explained on the following pages must
be performed to assure maximum
boiler efficiency and reliability. Fail-
ure to service and maintain the boiler
and system could result in equipment
failure.
Electrical shock hazard — Turn off
power to the boiler before any service
operation on the boiler except as noted
otherwise in this instruction manual.
Failure to turn off electrical power
could result in electrical shock, causing
severe personal injury or death.
Address reported problems
Inspect any problems reported by owner and correct before 1.
proceeding.
Inspect boiler area
Verify that boiler area is free of any combustible materials, 1.
gasoline and other flammable vapors and liquids.
Verify that air intake area is free of any of the contaminants 2.
listed on page 16 of this manual. If any of these are present
in the boiler intake air vicinity, they must be removed. If
they cannot be removed, reinstall the air and vent lines per
this manual.
Inspect boiler interior & door gaskets
Remove jacket front door and inspect interior of boiler.1.
Visually inspect the door gaskets. Make sure all are in good 2.
condition. Obtain replacements if any gasket is damaged.
Door gaskets must be intact, and must provide a
reliable seal. Replace any damaged gasket.
Remove the venturi air inlet silencer and clean if necessary. 3.
Replace silencer.
Vacuum any sediment from the inside of the boiler and 4.
components. Remove any obstructions.
Do not use solvents to clean any of the boiler
components. The components could be damaged,
resulting in unreliable or unsafe operation.
Clean condensate trap
Loosen condensate trap line hose clamps and remove trap 1.
line.
Empty water from trap line and inspect. Flush out if needed 2.
with fresh water.
Check condensate elbow and tee and condensate line to drain. 3.
Flush if necessary to clean.
Reinstall condensate trap line and tighten hose clamps.4.
Fill trap with fresh water by pouring into upturned end of 5.
PVC condensate tee.
Check all piping for leaks
Eliminate all system or boiler leaks. Continual fresh
make-up 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.
Inspect all water and gas piping and verify to be leak free.1.
Look for signs of leaking lines and correct any problems 2.
found.
Check gas line using procedure on 3. page 25.
Check air openings
Verify that combustion and ventilation air openings to the 1.
boiler room and/or building are open and unobstructed.
Check operation and wiring of automatic combustion air
dampers, if used.
Verify that boiler vent discharge and air intake are clean and 2.
free of obstructions.
Flue vent system and air piping
Visually inspect entire flue gas venting system and combus-1.
tion air piping for blockage, deterioration or leakage. Repair
any joints that show signs of leakage in accordance with vent
manufacturer’s instructions. When air is ducted to boiler,
verify that air inlet hose is connected and properly sealed.
Failure to inspect for the above conditions and have
them repaired can result in severe personal injury
or death.
Check water system
Verify all system components are correctly installed and 1.
operational.
Check the cold fill pressure for the system. Verify it is correct 2.
(usually around 12 psig).
Watch the system pressure as the boiler heats up (during 3.
testing) to ensure pressure doesn’t rise too high. Excessive
pressure rise indicates expansion tank sizing or performance
problem.
