Vulcan-Hart 7800 Pilot Burner Adjustments, Open TOP Burner Pilot Adjustments, Oven Adjustments

NOTE: All pilot adjustments are to be performed only by certified Vulcan service representatives.

OPEN TOP BURNER PILOT ADJUSTMENTS

TOOLS: Standard screwdriver.

After pilot is lit, turn the open top burner(s) ON. Adjust the flame if necessary. To adjust, rotate the pilot valve adjustment screw provided on the unit manifold pipe. Turn the burner ON; burner flame should appear on the burner head within a second. Rotate the screw clockwise to decrease and counterclockwise to increase the flame.

Check the open top burner nozzle relationship. The burner nozzle should enter approximately 1⁄4" inside the burner venturi (Fig. 2).

Pilot Safety Adjustment

With control panel cover removed, light the oven pilot as explained in the oven lighting instructions. If pilot goes out, increase the pilot safety adjustment until the flame completely engulfs the safety device sensing bulb. The safety adjustment screw is located on the safety control below the red button.

Bypass Flame Adjustment (Oven and

Thermostatically Controlled Griddle)

NOTE: This adjustment must be made at time of appli- ance installation.

Ignite oven/griddle burner pilot. With oven/griddle cold, turn the thermostat dial slowly clockwise until main burner gas is heard snapping ON. Remove the dial. With a screwdriver, turn the bypass adjustment screw (Fig's. 3

&4) counterclockwise to increase the bypass flame, or clockwise to decrease it, until flame over the entire burner is approximately 1⁄8" high. The bypass adjustment screw is located to the left-hand side of the thermostat control for the oven section, and on top of the thermostat control for the griddle. After adjustment has been made, replace dial.
