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 20 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 & jacket door
gaskets
1. Remove jacket door and inspect interior of boiler.
2. Visually inspect the jacket door gaskets
on front of cabinet.
Make sure all are in good condition. Obtain replacements
if any gasket is damaged.
Jacket 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.
Reinstall 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. For cleaning condensate trap, see Figure 96.
2. Remove pedestal front access panel to access the condensate
trap, if floor standing.
3. Loosen the hose clamp connecting the condensate trap to the
condensate drain tube. (See Figure 96). Pull the trap down
to disengage the condensate drain tube.
4. Remove the clean out cap and remove the trap internal parts
as shown.
5. Clean all trap components.
6. Re-assemble trap assembly. Re-install all lower gaskets.
7. Make sure the trap ball moves freely when re-inserted.
8. Fill trap with fresh water by pouring into the top of the trap
body. Continue filling slowly until water begins flowing
out the condensate drain line. Make sure the trap line is
unobstructed and flows freely or follow the procedure on
page 99 under “Fill condensate trap with water.
9. Reattach the trap to the boiler condensate outlet. Push the
trap up until fully engaged. Then retighten the hose clamp
securing the trap to the tube. Check for secure connection.
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 the heat exchanger,
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 in the system and in the
boiler and correct any problems found.
3. Check gas line using procedure on page 57.

GAS-FIRED WATER BOILER – 80/110/150/199 BOILER MANUAL
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 95, page 105 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.
