NOTE: If the incoming line pressure is less than the minimum stated, then the manifold pressure cannot be set correctly.
1.Open the door and turn gas combination valve knob/extension arm to off.
2.Remove the 1/8" NPT plug (pressure tap) on the outlet side of the valve and attach a manometer.
NOTE: Gas manifold pressure can also be measured at the pressure tap in the manifold. On Kleenscreen battery fryers only, the drain pipe may need to be removed for access.
3.Turn the gas supply on.
4.Light the pilot burner and turn the gas combination valve knob/extension arm to on.
5.Set control thermostat to call for heat and verify the main burners light.
6.Observe the manometer pressure reading and compare to the pressure chart near the end of this procedure.
A.If other appliances are connected to the same gas line, turn them all on and check manometer pressure reading again. If a pressure drop of 1/2" water column or more is observed, then the gas supply needs to be checked by the gas line installer or the local gas company for adequate sizing.
B.If adjustment is necessary, continue with procedure.
7.Remove the adjustment screw cap to access the pressure adjustment screw.
NON FILTER READY SHOWN
A.To increase pressure, turn the screw clockwise. To decrease pressure, turn the screw counterclockwise.
NOTE: Accurate gas pressure adjustments can only be made with the gas on and the main burners lit.
8.Set pressure as outlined in gas pressure table.
9.Once the correct pressure has been set, turn the gas combination valve knob/extension arm to off and shut off the gas supply.
10.Replace the adjustment screw cap and 1/8" NPT plug (pressure tap) on the outlet side of the valve.
11.Check fryer for proper operation.
PILOT BURNER FLAME
ADJUSTMENT
NOTE: Verify the proper gas type (natural or propane) is being supplied to the fryer before proceeding.
1.Turn control thermostat to off.
2.Light pilot burner and leave gas combination valve knob/extension arm in the pilot position. Allow pilot to burn for
A.If pilot burner is not lighting or does not remain lit when the gas combination valve knob/extension arm is released, see TROUBLESHOOTING. Wait 5 minutes between pilot burner lighting attempts for unburned gas to vent.
3.Verify the inner cone of pilot burner flame is extending approximately 1/2" beyond the outer edges of the pilot shield.
