Start-up

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. Se-
vere 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 "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 interior 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 burners 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 operation.
Inspect base insulation
The boiler contains ceramic fiber and
fiberglass materials. Use care when han-
dling these materials per instructions on
page 33 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 severe personal injury,
death or substantial property damage.

GAS FIRED BOILERS
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 . . .
more than ½ of gauge glass or less than ¼" above bottom of
gauge glass).
have been completed.
Start the boiler
1. Steam boilers — Check boiler water level — Should be approximately
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 Supple-
ment, 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 im-
mediately. Do not start boiler again until corrected. Failure
to comply could result 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 corro-
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,
