Slip, Fall Hazards
Tripping Hazard! Do not install piping on floor surfaces. Maintain a clear path around the boiler.
Slip and Fall Hazard! Use a drip pan to catch water while draining the boiler. Maintain dry floor
surfaces.
Slip and Fall Hazard! Do not locate intake or exhaust terminations above a walkway; dripping of
condensate can cause icing of the walking surface. Refer to
Fall Hazard! Do not stand on boiler.
Chemical Hazards
Chemical Hazards from Cleaning Products. Use
caution when cleaning the system. The use of professional
assistance is recommended. Use safe procedures for the
disposal of all cleaning solutions.
Combustion Condensate – An acidic pH of
approximately 3.0 to 5.0 can be expected. Use PVC, CPVC, or other corrosion resistant piping for
drainage. Collection and disposal must be in accordance with all applicable regulations. A condensate
neutralization kit is available. Please contact your local Harsco Industrial, Patterson-Kelley representative for
more information.
Burn, Fire and Explosion Hazards
Burn, fire, and explosion hazards! Installation must be in strict conformance to all applicable
codes and standards including NFPA 54, ANSI Z223.1 and CAN/CSA B.149. Install all required vent
lines for gas devices. Refer to
Hazard from Incorrect Fuels! Possible fire, explosion, overheating, and damage. Do not use any
fuels except the design fuels for the unit.
Overfire Hazards! High pressure in gas supply could result in overfiring of this or other devices
supplied from the same source.
Fire and Explosion Hazards! Close the main gas shutoff before servicing boiler.
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! Pipes, vents, and boiler components could be hot. Do not touch piping or stack surfaces during
operation or immediately after shutdown of the boiler.
Burn Hazard! Hot flue! Use caution when servicing 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 the burner is installed correctly and blower/transition is securely fastened following
any maintenance performed on them. These connections may leak gas if assembled incorrectly.
Gas Leak Hazard! All threaded gas connections must be made using a pipe compound that is resistant to liquefied
petroleum gas. 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 pressure does not
exceed 14 inches W.C.
Overfire Hazard! Possible fire and explosion. Possible malfunction of regulators and/or gas safety shut off/control
valves. Maintain all gas train components in good condition. Do not alter wiring connections. Annual inspection by
factory-trained personnel for proper set-up and operation is recommended.
Overfire and Underfire Hazards! Possible fire, explosion, 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.
