Replace the
Front and Rear Orifices using the 1/2 “ deep well socket.
Reinstall the burners and venturi tubes into the air boxes. Replace the 3/8
” nuts and tighten completely.
Note: Use these instructions to convert this unit to High Altitude Specification for the Main Orifices.
LP GAS PRESSURE REQUIREMENTS
Inlet and manifold gas pressure checking taps are located on gas valve. A qualified installer shall take pressure
measurements at these ports to verify and set the correct gas pressures during the LP Kit installation. Manifold
pressure must be taken at the “MANIFOLD PRESSURE” tap and inlet pressure at the “INLET PRESSURE” tap with
the burner operating by a qualified installer. For a detail of the location of these taps see page

LPG PROPER INPUT RATES:
With the proper orifices installed, as specified above, this wall unit utilizing LP Gas will have a maximum input rate
of 23,500 Btu/Hr.
LEAK TESTING REQUIREMENTS
Prior to completing the conversion process , check for gas leaks with soap and water solution at all plumbing
joints prior to placing this appliance into operation. It is recommended that all gas-plumbing joints, factory in-
stalled and field installed are checked for leaks.
PILOT FLAME AND MAIN BURNER RELATIONSHIP VERIFICATION
Prior to completing the conversion process, the qualified service technician
must, light the pilot light and verify the relationship between the pilot light
flames and the main burner. The pilot light flames directed towards the propa-
gation ports on the burner must overlap the propagation ports on the burner.
The pilot light flames must be a minimum of ¾” long and must overlap the
propagation ports on the burner. Verify that the burner ignites quickly and the
burner flames propagate smoothly along the entire length of the burner.
PILOT FLAME LENGTH ADJUSTMENT
If the pilot light flame length is too short, the thermocouple may not detect voltage adequate to open the valve, a
qualified installer may adjust the length of the pilot light flames to meet the demand of the thermocouple.
Pilot
Main Orifices are located inside shutterbox (Front orifice shown, rear
orifice is located beneath rear burner shown installed, here).
