lines for gas devices.  See Section 4 below. 

·  Hazard from incorrect fuels!  Possible fire, explo-

sion, overheating, and damage.  Do not use any 
fuels except vaporized natural gas and propane.  
Under no circumstances is liquid fuel of any kind 
to be introduced in the boiler.  

·  Hazard from incorrect fuel connections!  Possible 

fire, explosion, overheating, and damage.  Do not 
attempt to connect the propane supply to the natu-
ral gas connection, or vice versa.   

·  Fire and explosion hazards!  Close both the natural 

gas and propane shutoffs before servicing boiler.  

·  Burn hazard!  Possible hot surfaces.  Do not touch 

gas vent during firing operation.  Use only factory 
recommended B-vent components.   

·  Fire and explosion hazards!  Use caution when 

servicing burner.  Propane 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 
burner is assembled.   

·  Gas leak hazard!  Test motorized gas valves annu-

ally for leakage as described in Section 4.4.6. 

·  Gas leak hazard!  All threaded gas connections 

must be made using a pipe compound that is resis-
tant to propane.  Do not use Teflon

ä 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 
regulator on either the natural gas or propane sup-
ply line.  

·  Overfire hazard!  Possible fire and explosion.    

Possible malfunction of regulators and/or motorized 
gas 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, 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.

·  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:

·  Environmental hazard!  The motorized gas valves 

may contain hydraulic oil.  Use safe procedures 
for the disposal of all lubricants.
