•  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 appli-
ance. 

•  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 

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 all connections to 

main burner are tight when reassembling the 
burner.  These connections cannot be tested af-
ter the burner is assembled. 

•  Gas leak hazard!  All threaded gas connections 

must be made using a pipe compound that is re-
sistant to liquefied petroleum.  Do not use Tef-
lon

™ 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 as-
sistance from factory-trained 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. to 
the regulator. 

•  Overfire hazard!  Possible fire and explosion.    

Possible malfunction of regulators and/or mo-
torized gas valves.  Maintain all gas train com-
ponents in good condition.  Do not alter wiring 
connections.  Annual inspection by factory-
trained personnel for proper set-up and opera-
tion 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 fac-
tory-trained personnel.  

 

2.5.3  Crush Hazards 
 

 

 

•  Lifting hazards!  Use properly rated lifting 

equipment to lift and position the boiler.  The 
load is unbalanced.  Test balance before lifting 3 
ft. above the floor.  Do not allow personnel be-
neath the lifted load.  Refer to approximate 
weights in the table below:  

 

Boiler Size 

Weight in Pounds 

1,000,000 Btu 

595 

1,500,000 Btu 

990 

2,000,000 Btu 

1,025 

 

 

•  Bump hazard from overhead piping.  Install pip-

ing with adequate vertical clearance.  

 

2.5.4  Chemical Hazards 
 

 

 

•  Environmental hazard!  The motorized gas 

valves may contain hydraulic oil.  Use safe pro-
cedures for the disposal of all lubricants.   

•  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.
