C. NATURAL GAS and 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, therefore, 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 is 10.5 inches (26.1 mb) for safe and efficient dryer operation. Low, inconsistent, or too high a gas pressure will result in improper operation of the dryer’s heat and safety circuits. POOR EFFICIENCY CAN
