PRESSURE REGULATION AND TESTING

DFG-50 ovens are rated at 27,500 BTU/Hr. (8.1 kW) (29 MJ) or 34,500 BTU/Hr. (10.1 kW) (36 MJ) per section. Each oven has been adjusted at the factory to operate with the type of gas specified on the rating plate.

DInlet Pressure --- the pressure of the gas before it reaches the oven.

DManifold Pressure --- the pressure of the gas as it enters the main burner(s).

DMin --- the minimum pressure recommended to operate the oven.

D Max --- the maximum pressure at which the manufacturer warrants the oven’s operation.

Each oven is supplied with a regulator to maintain the proper gas pressure. The regulator is essen- tial to the proper operation of the oven and should not be removed. It is preset to provide the oven with 3.5” W.C. (0.87 kPa) for natural gas and 10.5” W.C. (2.50 kPa) for Propane at the manifold.

DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE OVEN CONNECTS TO THE GAS SUPPLY UNLESS THE INLET PRESSURE IS ABOVE MAXIMUM.

Prior to connecting the oven, gas lines should be thoroughly purged of all metal filings, shavings, pipe dope, and other debris. After connection, the oven should be checked for correct gas pressure.

The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kPa).

The oven must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas piping system at test pressures equal or less than 1/2 psig (3.45kPa).
