Ultra Boiler Manual
Part number 550-100-440/0122
110
(continued)
e boiler should be inspected and started
annually, at the beginning of the heat-
ing season, only by a qualied service
technician. In addition, the maintenance
and care of the boiler designated in Fig-
ure118,page108 and explained on the
following pages must be performed to
assure maximum boiler eciency and
reliability. Failure to service and main-
tain the boiler and system could result
in equipment failure.
Electrical shock hazard — Turn o power
to the boiler before any service operation
on the boiler except as noted otherwise
in this instruction manual. Failure to
turn o electrical power could result in
electrical shock, causing severe personal
injury or death.
1. Inspect any problems reported by owner and correct before
proceeding.
1. Verify that boiler area is free of any combustible materials,
gasoline and other ammable vapors and liquids.
2. Verify that air intake area is free of any of the contaminants
listed on page16 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.
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. e 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.
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 page29.
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.
1. Visually inspect entire ue gas venting system and combus-
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.
1. Verify all system components are correctly installed and
operational.
2. Check the cold ll 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.
