A.
General Housekeeping (Continuous).
1. Keep boiler area clear and free of combustible
materials and obstructions to the free flow of
combustion and ventilation air to the boiler.
2. Do not store or use gasoline or other flammable
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 qualified 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 flame(s) and main burner flame should be checked
annually, after each flueway 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 flame(s) and main burner flame,
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 flames, one left, one right
and one straight ahead. The center or straight
ahead flame should be a blue medium hard flame
enveloping approximately 3/8" of the end of the
sensing probe mounted on the pilot burner, see
Figure 9. If the flame is yellow and lazy, a qualified
service agency should be called.
2.
Main Flame
Main burner flame should have a clearly defined
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 flames
are observed, a qualified service agency should be
called.
After flame 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 qualified service
agency. Inspections should be performed at intervals specified 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 flammable vapors and liquids.
Do not place any obstructions in boiler room that will hinder flow of combustion and ventilation air.
