To convert manual units from propane to natural gas or from natural to propane gas, carefully follow the steps
below:
1. SHUT OFF THE GAS SUPPLY TO THE UNIT AND ANY NEARBY ELECTRICAL SOURCES OR
APPLIANCES.
2. If present, remove all decorative media from the unit.
3. Remove the screws attaching the burner pan to your enclosure.
4. Detach the thermocouple (taking care not to kink it) from the safety valve (see Fig.
16-2 for location).
5. Carefully detach the fl ex connector attached to the orifi ce holder (see Fig. 16-4) and unscrew the orifi ce
holder from the burner pipe (see
Fig. 16-5).
6. Remove the orifi ce from the holder (see Fig. 16-5) and replace with the proper-sized one for your gas
requirement. Propane gas requires a #40 (drill size) orifi ce. Natural gas requires a #23 orifi ce.
Note: If you are converting to and using natural gas you MUST install the air shutter
over burner pipe to cover the air holes (see
Fig. 16-5). For propane (L.P.) gas,
remove the air shutter.
Replace the orifi ce holder and reattach the connector from the valve (see
Fig. 16-4).
The regulator must now be converted to the new gas type.
7. The regulator is situated after the valve (see Fig.
16-2), behind the control panel. To
convert the regulator to the required gas type:
a) Unscrew and remove the cap (see Fig.
16-1) from the regulator, extracting the
converter.
Note: As installed, the regulator cap may be located underneath the regulator. If
necessary, carefully rotate the regulator to access the cap.
b) Remove the converter (the red plastic stalk, Fig.
16-1) by carefully pulling it away from the center of the
cap (it will snap out of its seating).
c) Turn the converter around and replace carefully into the center of the cap (it will snap into place). Check
that you can read the type of gas the unit is set for.
Note: EACH END OF THE PLASTIC CONVERTER IS EMBOSSED WITH EITHER THE LETTERS “NAT”
OR “L.P.” FOR THE RESPECTIVE GAS TYPE ("NAT." for natural - "L.P." for propane). WHEN
THE CONVERTER IS IN THE CAP AND THE CAP IS HELD UPPERMOST, THE LETTERS SEEN
(AT THE BOTTOM OF THE STALK) INDICATE THE GAS THAT THE REGULATOR IS SET UP
FOR. (Fig.
16-1 shows the converter set for propane gas.)
d) Replace the cap and converter into the regulator and screw down until snug.
8. Once the above steps are complete, reattach the thermocouple and ignitor wires.
9. Restore your gas supply and check for leaks per the INSTALLATION section. When no leaks are detected,
fasten the burner pan back into place on the enclosure and replace the decorative media.
