flow (propane gas) or parallel to gas flow (natural

This heater is shipped from the factory with the
fuel selector valve in the propane gas (LP)
position. Ensure the fuel selector valve’s handle
is properly positioned for the fuel being used.
1. This feature allows the heater to operate on either
propane or natural gas without changing out the
burner orifice. The gas selector valve is located
between the gas control valve and the burner. Gas
selection is made by sliding the locking sleeve (if
provided) up and repositioning the valve’s handle.
THIS IS NOT A MANUAL GAS SHUT OFF VALVE.
2. Refer to Figs. 19 and 20. The valve handle must
be properly positioned for the specific gas being
used (Premier 170 DF shown. Same handle posi-
tions for Premier 80 DF).
