OVEN BURNER NOZZLE AND ORIFICE CHECK

If burner operation seems poor and all other systems have been verified, remove burner nozzle and orifice to check for blockage or damage. Blockages can often be cleaned using water pressure and a mild soap solution or by running a correct size drill tap through the nozzle opening.

OVEN BURNER NOZZLE AND ORIFICE REPLACEMENT

TOOLS REQUIRED: 1/2" open end wrench.

1.Disconnect unit from gas and allow unit to cool.

2.Follow steps listed under the replacement of the safety valve in order to access the oven burner nozzle.

3.Remove burner nozzle.

4.Remove orifice spud.

5.Check for blockage or damages (Fig. 44).

NOTE: If blockage is apparent, the obstruction can either be cleaned or the entire nozzle assembly replaced. Verify also that the proper nozzle orifice size is being used, and verify BTU rating with flow meter. (Flow meter kits are available from Vulcan-Hart Service Parts Depots under Part No. 495.)

FOR PROPER USAGE OF FLOW METER, REFER TO THE MANUFACTURER’S INSTRUCTIONS PROVIDED IN THE FLOW METER KIT.
