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

B. Gas Pressures
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.
WARNING
Verify inlet pressures.
• High pressure may cause overfi re condition.
• Low pressure may cause explosion.
Install regulator upstream of valve if line pressure
is greater than 1/2 psig.
Pressure requirements for appliance are shown in the table
below.
PRESSURE
Minimum Inlet Pressure
Maximum Inlet Pressure
Manifold Pressure on "HI"
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.
