Fire Risk.
Explosion Risk.
  If the information in these instructions is 
not followed exactly, a fire, explosion or 
production of carbon monoxide may result 
causing property damage, personal injury 
or loss of life.  
•  The qualified service agency is responsible 
for the proper installation of this conversion 
kit.  The installation is not proper and 
complete until the operation of the converted 
appliance is checked as specified in the 
manufacturer’s instructions supplied with 
the kit.

   Ensure that the rubber gasket (D) is properly posi-
tioned and install the new HI/LO pressure regulator assem-
bly to the valve using the new screws (E) supplied with the 
kit. Tighten screws securely. (Reference torque = 25 in./lb.)  
Install the enclosed identification label (F) to the valve body 
where it can be seen.
Fill out the conversion label and attach it to the valve cover.
WARNING

Explosion Risk.
Gas Leak Risk.
•  Rubber gasket must be seated properly on valve 
face.
•  Do no install a valve or regulator that has been 
dropped.
B. Gas Pressures
If the pressure is not sufficient, ensure: 
1) the piping used is large enough. 
2) the supply regulator is adequately adjusted.
3) that  the total gas load for the residence does not exceed 
the amount supplied.
The supply regulator (the regulator that attaches directly to the 
residence inlet or to the propane tank) should supply gas at 
the suggested input pressure listed above.  Contact the local 
gas supplier if the regulator is at an improper pressure.
Pressure requirements for appliance are shown in the table 
below.
Proper input pressures required for optimum appliance per-
formance, gas line sizing requirements need to be followed 
from NFPA51.
WARNING
Fire Risk.
Explosion Hazard.
High pressure will damage valve.
•  Disconnect gas supply piping BEFORE 
pressure testing gas line at test pressures 
above 1/2 psig.
•  Close the manual shutoff valve BEFORE 
pressure testing gas line at test pressures 
equal to or less than 1/2 psig.
