The following terms are used throughout this manual to bring attention to the presence of hazards of various risk levels.
Important Product Safety Information
Refractory Ceramic Fiber Product
The Repair Parts list designates parts that contain refractory ceramic fibers
(RCF). RCF has been classified as a possible human carcinogen. When
exposed to temperatures above 1805°F, such as during direct flame contact,
RCF changes into crystalline silica, a known carcinogen. When disturbed as a
result of servicing or repair, these substances become airborne and, if inhaled,
may be hazardous to your health.
AVOID Breathing Fiber Particulates and Dust
Precautionary Measures:
Do not remove or replace RCF parts or attempt any service or repair work
involving RCF without wearing the following protective gear:
1. A National Institute for Occupational Safety and Health (NIOSH)
approved respirator
2. Long sleeved, loose fitting clothing
3. Gloves
4. Eye Protection
•Take steps to assure adequate ventilation.
•Wash all exposed body areas gently with soap and water after contact.
•Wash work clothes separately from other laundry and rinse washing
machine after use to avoid contaminating other clothes.
•Discard used RCF components by sealing in an airtight plastic bag. RCF
and crystalline silica are not classified as hazardous wastes in the United
States and Canada.
First Aid Procedures:
•If contact with eyes: Flush with water for at least 15 minutes. Seek
immediate medical attention if irritation persists.
•If contact with skin: Wash affected area gently with soap and water.
Seek immediate medical attention if irritation persists.
•If breathing difficulty develops: Leave the area and move to a location
with clean fresh air. Seek immediate medical attention if breathing
difficulties persist.
•Ingestion: Do not induce vomiting. Drink plenty of water. Seek
immediate medical attention.
Indicates a potentially hazardous situation which,
if not avoided, could result in death, serious injury
or substantial property damage.
Indicates a potentially hazardous situation which,
if not avoided, may result in moderate or minor
injury or property damage.

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 qualied 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 qualied
service agency should be called.
2. Main Flame
Main burner ame should have a clearly dened
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 qualied 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 qualied service
agency. Inspections should be performed at intervals specied 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.

D. Examination of Flue Product Carrying Areas.
1. Boiler
Flue passageways in the boiler sections should be
checked annually for any blockage or accumulation
of soot. A think layer of soot on the ue gas
passageways will affect heat transfer substantially.
The resultant loss in efciency will have a direct
bearing on increased fuel consumption.
Blockage of the ues is hazardous. If severe, carbon
monoxide concentrations could be lethal during the
burning cycle. Flames could roll outside the jacket
creating a re hazard. The heat concentration could
severely damage the base, warp the burners, melt
the pilot tubing and wire insulation and destroy the
ignition module inside the jacket vestibule.
To obtain access to the ue cleanout panels, which
are installed on both the front and rear of the boiler,
the upper front and upper rear jacket panels must be
removed.
If access to the ue cleanout panels facing the front
of the boiler is required, the front vestibule panel
must be removed. See Figure 11.
Remove the Front Cleanout Panels rst by removing
the upper and lower nuts and washers securing these
panels to the boiler sections, see Figure 11.
CARE SHOULD BE EXERCISED IN
REMOVING THE CLEANOUT PLATES FROM
THE BOLTS SO THAT THE INSULATION IS
NOT DAMAGED. IF DAMAGED, ALL EDGES
OF THE CLEANOUT PLATES SHOULD BE
SEALED WITH BOILER PUTTY WHEN
REINSTALLED UNTIL INSULATION CAN BE
REPLACED.
Using a ashlight, examine all ue passageways. If
passageways are free of soot and obstruction, it is
not necessary to remove the rear cleanout panels.
If the ues need cleaning or are obstructed, call a
qualied service agency.
