C. Natural Gas To L.P. (Liquid Propane) Gas Conversion Instructions
IMPORTANT: CONVERSION MUST BE PERFORMED BY COMPETENT TECHNICIANS
IN ACCORDANCE WITH LOCAL and STATE CODES.
NOTE: Converting the dryer to L.P. Gas disables the internal regulator of the gas valve, there-
fore, an external regulator must be provided at the source of the L.P. gas supply (L.P. tank)
or the dryer. The water column (W.C.) gas pressure must be regulated to between 10.5 inches
and 11 inches for safe and efficient dryer operation. Low, inconsistent, or too high a gas
pressure will result in improper operation of the dryers' heat and safety circuits. POOR
EFFICIENCY CAN CREATE A POTENTIAL SAFETY HAZARD.
1. Discontinue electrical power to the dryer.
2. Close
ALL gas shut-off valves in the dryers' gas supply line.
Turn the gas cock dial to the off position on the gas valve.
3. Disconnect the gas valve wiring.
Be sure to identify the correct location of each wire for correct reinstallation.
4. Disconnect union connection in the gas supply line.
IMPORTANT: Pipe joint compounds that resist the action of natural gas and L.P. gas must be
used.
5. Loosen and remove the screws from the brackets holding the gas valve and manifold assembly to the burner
box.
6. Remove the gas valve and manifold assembly from the dryer.
7. Unscrew the main burner orifices and replace them with the L.P. orifices provided.
NOTE: Use extreme care when handling (removing or replacing) orifices. THESE ORIFICES
ARE MADE OF BRASS and CAN BE EASILY DAMAGED.
8. Remove the two (2) screws on the gas valve regulator.
Remove the regulator and the gasket.
9. Install the new gasket and L.P. regulator.
Replace the two (2) screws.
NOTE: USE ONLY NEW PARTS PROVIDED.
10. Reverse the procedure for reinstalling the gas valve and manifold assembly to the dryer.
11. Open ALL gas shut-off valves (closed in Step #2).
