The rating plate is stamped with the model number, type of
gas and gas input rating. Make sure the unit is equipped to
operate on the type of gas available. Conversion to LP gas
is permitted with the use of the factory authorized conver-
sion kit LPM-07, for use with single stage models, or LPM-
08, for use with two-stage models. See table below.

Inlet Gas Pressure
Natural Min. 5.0" W.C., Max. 10.0" W.C.
Propane
Min. 11.0" W.C., Max. 13.0" W.C.
Inlet Gas Pressure must be within the minimum and maxi-
mum value shown in table above.
The minimum supply pressure should not vary from that
shown in the table above because this could prevent the
unit from having dependable ignition. In addition, gas input
to the burners must not exceed the rated input shown on

codes.
2. Use pipe joint compound on male threads only. Pipe
joint compound must be resistant to the action of the
fuel used.
3. Use ground joint unions.
4. Install a drip leg to trap dirt and moisture before it can
enter the gas valve. The drip leg must be a minimum
of three inches long.
5. Use two pipe wrenches when making connection to
the gas valve to keep it from turning.
