Operate boiler
Check system and boiler
DO NOT proceed with boiler operation unless
boiler and system have been filled with water and
all instructions and procedures of previous manual
sections have been completed. Failure to do so could
result in severe personal injury, death or substantial
property damage.
Before starting the boiler . . .
• SeeControlSupplementfor“LightingorOperating
Instructions”.
• Verifytheboilerandsystemwaterleveliscorrect
(Steam — no more than ½ of gauge glass or less
than ¼” above bottom of gauge glass).
• Verifythe“Preparationproceduresontheprevious
pages have been completed.
Start the boiler
1. Steam boilers — Check boiler water level — Should be ap-
proximately ½ way up gauge glass.
2. Remove boiler jacket door and note the gas valve manufacturer
and model number.
3. Follow the Lighting or Operating Instructions in the Control
Supplement, depending on gas valve installed in boiler. Use
only the Operating Instruction which applies to this gas valve.
(The Operating Instruction label on the boiler provides the
same information.)
4. If boiler fails to start, see “If boiler doesn’t start . . . Check for:”
on the next page.
Check system and boiler
Eliminate all system leaks. Continual fresh makeup
water will reduce boiler life. Minerals can build up
in sections, reducing heat transfer, overheating cast
iron, and causing section failure.
If you discover evidence of any gas leak, shut down
the boiler at once. Find the leak source with bubble
test and repair immediately. Do not start boiler
again until corrected. Failure to comply could re-
sult in severe personal injury, death or substantial
property damage.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to
boiler will occur, resulting in substantial property
damage.
1. Check system piping for leaks. If found, shut down boiler and
repair immediately.
2. Inspect vent system thoroughly for signs of deterioration from
corrosion, physical damage or sagging. Verify that masonry
chimney liners are in good condition, with no obstructions,
and there are no openings into the chimney.
3. Check around the boiler for gas leaks following the procedure
of step 13, page 22.
4. Verify operation using procedures below. Perform “Checkout
procedure, page 28, and fill in the “Installation and Service
Certificate”.
Skim the steam boiler
Clean all newly installed steam boilers to remove
oil and grease. Failure to properly clean can result
in violent fluctuations of water level, water passing
into steam mains or high maintenance costs on
strainers, traps and vents.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to
boiler will occur, resulting in substantial property
damage.
1. Provide 1½” piping from skim tapping to floor drain.
2. Adjust waterline to midpoint of skim tapping. See Figure 5,
page 10.
3. Follow “Lighting or Operating Instructions in the Control
Supplement to fire boiler to maintain temperature below
steaming rate.
4. Feed in water to maintain water level. Cycle burners to prevent
rise in steam pressure.
5. Continue skimming until discharge is clear. May take several
hours.
6. Drain boiler. While boiler is warm, but not hot, flush all inte-
rior surfaces under full pressure until drain water runs clear.
7. Remove skim piping. Plug tapping.
8. Close drain cock. Fill with fresh water to waterline. Start burn-
ers and steam for 15 minutes to remove dissolved gases. Stop
burners.
9. Check traps and air vents for proper operation.
10. Process may need to be repeated after several weeks of opera-
tion.
Inspect base insulation
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 29 of this manual. Failure
to comply could result in severe personal injury.
Check to make sure insulation is secure against all four sides of
the base. If insulation is damaged or displaced, do not operate
boiler. Replace or reposition insulation.
Failure to replace damaged insulation or reposition
insulation can result in a fire hazard, causing se-
vere personal injury, death or substantial property
damage.
