Fire Risk.
Explosion Risk.
• If the information in these instructions is
not followed exactly, a fi re, explosion or
production of carbon monoxide may result
causing property damage, personal injury
or loss of life.
• The qualifi ed 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 specifi ed in the
manufacturer’s instructions supplied with
the kit.
WARNING

Figure 6.7 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 identifi cation label (F) to the valve body
where it can be seen.
Fill out the conversion label and attach it to the valve cover.
WARNING
Fire Risk.
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 suffi cient, 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.
PRESSURE NG LP
Minimum Inlet Pressure 4.5 inches w.c. 11.0 inches w.c.
Maximum Inlet Pressure 7.0 inches w.c. 14.0 inches w.c.
Manifold Pressure on “HI” 3.5 inches w.c. 10.0 inches w.c.
WARNING
Verify inlet pressures.
• High pressure may cause overfire
condition.
• Low pressure may cause explosion.
• Verify minimum pressures when other
household gas appliances are operating.
Install regulator upstream of valve if line pressure
is greater than 1/2 psig.
