Contact your gas company for correct supply line sizes.
Purge the supply line to clean out any dust, dirt, or foreign matter before connecting the line to
the unit.

must be a type that is resistant to the action of liquified petroleum or
propane gases.
Codes require that a gas shut-off valve be installed in the gas line prior to the unit. Make sure
the pipes are clean and free of obstructions, dirt, and piping compound.
WARNING: Prior to start-up, check all joints in the gas supply line
for leaks. Use soap and water solution. Do not use an open flame.
Do not connect the appliance to the electrical supply until after the gas connection has been
