CAUTION: DO NOT redrill burner orifices. Improper drilling (burrs, out-of-round holes, etc.) can cause excessive
burner noise and misdirection of burner flames. This can result in flame impingement of the burners and heat exchangers,
causing failure. Obtain new orifices if orifice size must be changed.
NOTE:
Air opening above burners will now be partially obstructed by air shutter.
PROCEDURE 3—INSTALL DIVERTER PLATE
1. Install diverter plate (provided in kit) above combustion air intake box as follows:
a. Remove front 2 screws on combustion air intake box. (See Fig. 13.)
b. Remove combustion air intake box and set aside. (See Fig. 13.)
c. If air diffuser has a solid center, remove center section of air diffuser.
•Remove burners.
•Remove center solid portion of air diffuser. (See Fig. 14.) Use tin snips to cut center portion of air diffuser. Do not overly distort air
diffuser. The air diffuser is Tog-L-Locked to burner box.
•Replace burners.
d. Install diverter plate Part No. 323184-301 provided in kit. (See Fig. 15.)
e. Reinstall combustion air intake box and replace 2 screws to ensure diverter plate is properly installed. (See Fig. 15.)
2. Reinstall manifold, orifice, and gas-valve assembly in burner box. Ensure manifold seal grommet is installed properly and burners fit over
orifices. (See Fig. 16 for ignitor position.)
3. Reconnect wires to gas valve. Refer to furnace wiring schematic for proper wire location.
4. Reinstall burner box pressure tube to gas-valve regulator fitting.
5. Reconnect gas supply pipe to gas valve using backup wrench on gas valve to prevent rotation and improper orientation.
NOTE: Use propane-gas-resistant pipe dope to prevent gas leaks. DO NOT use Teflon tape.
NOTE:
DO NOT reinstall burner enclosure front at this time.
PROCEDURE 4—PRE-ADJUST GAS VALVE
CAUTION: The gas valve must be pre-adjusted before operating on propane gas. Failure to follow this caution could
result in excess underfire and flashback. If left this way sooting and corrosion will occur leading to early heat exchanger
failure.
1. Be sure gas and electrical supplies to furnace are off.
2. Remove caps that conceal adjustment screws for high-and low-heat stage gas valve regulators. (See Fig. 11.)
3. Turn low-heat stage adjusting screw (5/64-in. hex allen wrench) clockwise (in) 1 full turn. This will increase the manifold pressure closer
to the propane low-heat set point.
4. Turn high-heat stage adjusting screw (5/64-in. hex allen wrench) clockwise (in) 2 full turns. This will increase the manifold pressure closer
to the propane high-heat set point.
5. Replace caps that conceal gas valve regulator adjustment screws.
PROCEDURE 5—CHECK INLET GAS PRESSURE
NOTE:
This kit is to be used only when inlet gas pressure is between 11.0-in. wc and 13.6-in. wc.
1. Be sure main gas and electrical supplies to furnace are off.
2. Remove 1/8-in. pipe plug from inlet pressure tap on gas valve. (See Fig. 11.)
3. Attach manometer to inlet pressure tap on gas valve. (See Fig. 17.)
CAUTION: DO NOT operate furnace more than 1 minute to check inlet gas pressure as conversion is not complete at
this time.
