A. General Housekeeping (Continuous).
1. Keep boiler area clear and free of combustible
materials and obstructions to the free ow of
combustion and ventilation air to the boiler.
2. Do not store or use gasoline or other ammable
vapors or liquids in the vicinity of the boiler or any
other appliance.
3. Do not store or use sources of hydrocarbons in
the vicinity of the boiler. Sources of hydrocarbons
include bleaches, cleaners, chemicals, sprays, paint
removers, fabric softeners, cat litter and refrigerants.
B. Inspect Vent System (Monthly). See Figure 8. Follow
instructions TO TURN OFF GAS TO APPLIANCE
(see Figures 2 thru 4) and contact a qualied service
agency if any of the following conditions are found:
1. Collapsed vent pipe
2. Disconnected or loose joints
3. Sags in horizontal runs
4. Corrosion or other deterioration
5. Broken or loose supports
C. Examination of Pilot and Main Burner Flames.
Pilot ame(s) and main burner ame should be checked
annually, after each ueway cleaning, or after an
extended shutdown period. Six through 14 section
boilers are equipped with one (1) pilot, whereas larger
than 14 section boilers are equipped with two (2) pilots.
To observe the pilot ame(s) and main burner ame,
remove the Lower Front Jacket Panel(s) by grasping
the knobs on the panel, and while pushing up on the
panel, pull out on the bottom of the panel. Immediately
behind the Lower Jacket Front Panel are a number of
observation port covers. Select a cover that is directly
behind a pilot, loosen the screw at the top of the cover
and with a pair of pliers (cover may be hot) rotate cover
until observation port is uncovered. Retighten screw to
hold cover in this position.
1. Pilot Flame
All of the pilots used on the Series 5B boilers have
tips that produce three ames, one left, one right
and one straight ahead. The center or straight
ahead ame should be a blue medium hard ame
enveloping approximately 3/8" of the end of the
sensing probe mounted on the pilot burner, see
Figure 9. If the ame is yellow and lazy, a qualied
service agency should be called.
2. Main Flame
Main burner ame should have a clearly dened
inner cone, see Figure 10, with no yellow tipping.
Orange-yellow streaks caused by dust should not be
confused with true yellow tipping. If yellow ames
are observed, a qualied service agency should be
called.
After ame observations have been completed,
relocate port cover so the observation hole is closed,
then secure cover in this position. Reinstall Lower
Jacket Front Panel.
User Maintenance
Service on this boiler should be undertaken only by trained and skilled personnel from a qualied service
agency. Inspections should be performed at intervals specied in Installation, Operating and Service
Instructions and this manual. Maintain manuals in a legible condition.
Keep boiler area clear and free of combustible materials, gasoline and other ammable vapors and liquids.
Do not place any obstructions in boiler room that will hinder ow of combustion and ventilation air.
