For full input, refer too SPECIFICATIONS, page 2, for minimum gas pressure required. For
reduced capacities, refer to Firing Rate Curves, Table 2.
CAUTION: If gas supply pressure is below its specifi ed range during adjustment, an
over-fi re condition could result when pressure returns to normal, particularly if the regulator
adjustment screw is bottomed out. ALWAYS confi rm that at least the minimum rated pressure
is being supplied during regulator adjustments, and NEVER BOTTOM OUT regulator screw.
-
When selecting the burner supply piping size per Table 1, the permissible pressure drop must
be based on the pressure available at the inlet to the supply pipe branch line when all other gas
equipment fed by the same source (NATURAL gas meter or PROPANE tank regulator) is fi ring at full
rate. Also take into account any other INCINOMITE burners to be attached to the same branch line.
-
When pressure testing the supply piping, the burner valve train must be protected. If the test
pressure is 0.5 PSIG or less, closing the Main Manual Shut-Off Valve will suffi ce.
CAUTION: If the test pressure is over 0.5 PSIG, the test must be made without any
burner components connected.
DANGER: EXPLOSION HAZARD. DO NOT USE OXYGEN FOR PRESSURE
TESTING. AN EXPLOSION COULD OCCUR DURING INITIAL START-UP.
