These instructions are for the conversion of Direct Fired Heater
Models with the Dungs Gas Valve. Please make sure that the
model you are converting has the Dungs Gas Valve. (See Figure
1 for verification.)
STEP 1: PREPARATION
Turn off all electrical power to the heater. Shut off the gas with
the manual shutoff before beginning the conversion. Make sure
that you are properly connected to the gas supply. Check the gas
piping and pressure to assure proper sizing for the heater firing
rate. It is recommended that you contact your gas supplier to
verify correct gas piping size and proper connection. It may also
be necessary to install a 100% lockup gas pressure regulator of
sufficient size to supply the correct pressure and gas flow.
