If a 2nd stage regulator is used, the ball valve down stream in the supply line must be closed when purging
the gas lines to prevent gas seeping through it. If initial gas pressure is higher than 14” w.c. the redundant
combination gas valve is designed to lock out. Pressure build-up in the supply lines prior to the heater must
be released before proper heater operation.
