Address Reported Problems; Inspect Boiler Area - Weil-McLain Ultra Manual

-
gas fired water boiler
Annual startup
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 Table 5 and explained on
the following pages must be performed
to assure maximum boiler efficiency
and reliability. Failure 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

1. Inspect any problems reported by owner and correct before
proceeding.

Inspect boiler area

1. Verify that boiler area is free of any combustible materials,
gasoline and other flammable vapors and liquids.
2. Verify that air intake area is free of any of the contaminants
listed on page 8 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 and the Ultra Boiler Vent Supplement.
Inspect boiler interior & door gaskets
1. Remove jacket front door and inspect interior of boiler.
2. Visually inspect the door gaskets. Make sure all are in good
condition. Obtain replacements if any gasket is damaged.
Door gaskets must be intact, and must provide a
reliable seal. Replace any damaged gasket.
3. Remove the venturi air inlet silencer and clean if necessary.
Replace silencer.
4. Vacuum any sediment from the inside of the boiler and
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
1. Loosen condensate trap line hose clamps and remove trap
line.
2. Empty water from trap line and inspect. Flush out if needed
with fresh water.
3. Check condensate elbow and tee and condensate line to drain.
Flush if necessary to clean.
4. Reinstall condensate trap line and tighten hose clamps.
5. Fill trap with fresh water by pouring into upturned end of
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.
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. Check gas line using procedure on
Check air openings
1. Verify that combustion and ventilation air openings to the
boiler room and/or building are open and unobstructed.
Check operation and wiring of automatic combustion air
dampers, if used.
2. Verify that boiler vent discharge and air intake are clean and
free of obstructions.
Flue vent system and air piping
1. Visually inspect entire flue gas venting system (and air pip-
ing, if installed) 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
1. Verify all system components are correctly installed and
operational.
2. Check the cold fill pressure for the system. Verify it is correct
(usually around 12 psig).
3. Watch the system pressure as the boiler heats up (during
testing) to ensure pressure doesn't rise too high. Excessive
pressure rise indicates expansion tank sizing or performance
problem.
