Gas-Fired Boiler Safety
Page 3
•
Fire and explosion hazards! Do not store or use
gasoline or other flammable vapors or liquids in
the vicinity of this or any other gas fired appliance.
•
Burn hazard! Possible hot surfaces. Do not touch
gas vent during firing operation. Use only factory
recommended vent components.
•
Burn hazard! Hot fluids. Use caution when ser-
vicing or draining boiler.
•
Fire and explosion hazards! Use caution when
servicing burner. Propane (LPG) is heavier than
air and may linger in the combustion chamber,
vent lines, or elsewhere.
•
Gas leak hazard! Make sure all connections to
main burner are tight when reassembling the
burner. These connections cannot be tested after
the burner is assembled.
•
Gas leak hazard! All threaded gas connections
must be made using a pipe compound that is resis-
tant to liquefied petroleum.
Do not use Teflon

tape on threaded gas piping.
•
Gas leak hazard! Check entire gas train for leaks
after installation. If there is a smell of gas, shut
down the boiler and obtain immediate assistance
from trained service personnel and/or your local
fire department.
•
Overfire hazard! Possible fire and explosion from
excess gas pressure. Make sure that gas inlet pres-
sure does not exceed 14 inches W.C. to the regula-
tor.
•
Overfire hazard! Possible fire and explosion.
Possible malfunction of regulators and/or motor-
ized gas valves. Maintain all gas train components
in good condition. Do not alter wiring connec-
tions. Annual inspection by factory-trained per-
sonnel for proper set-up and operation is recom-
mended.
•
Overfire and underfire hazards! Possible fire, ex-
plosion, overheating, and component failure. Do
not attempt to adjust firing rate of the boiler. The
firing rate must be adjusted
only by factory trained
personnel.
2.5.3 Crush Hazards
General Warning
•
Lifting hazards! Use properly rated lifting equip-
ment to lift and position the boiler. The load is
unbalanced. Test balance before lifting 3 ft. above
the floor. Do not allow personnel beneath the
lifted load. Refer to approximate weights in the
table below:
Boiler Size Weight in Pounds
700,000 Btu 595
1,000,000 Btu 595
1,200,000 Btu 685
1,500,000 Btu 990
1,700,000 Btu 985
2,000,000 Btu 1,025
•
Bump hazard from overhead piping. Install piping
with adequate vertical clearance.
2.5.4 Chemical Hazards
•
Environmental hazard! The motorized gas valves
may contain hydraulic oil. Use safe procedures
for the disposal of all lubricants.
•
Chemical hazards from cleaning products. Use
caution when cleaning the system. The use of pro-
fessional assistance is recommended. Use safe
procedures for the disposal of all cleaning solu-
tions.
