Theory of Operation: A natural gas burning appliance requires roughly 10 cubic feet of air to properly combust a single cubic foot of gas. Minute airborne particles entrained during this process pass through the combustion system and are incinerated. However, some particles may be trapped within the combustion system, building up over time, causing an eventual decrease in the operational efficiency of your appliance. The rate at which this build up may occur varies from kitchen to kitchen and is

Follow this procedure for Installation of Self Cleaning burners and SCBS arm: a. Disconnect the control harness from the main gas valve and tuck it out the way to avoid damaging the harness during this procedure. b. If your appliance has a solid-state control (or auxiliary thermostat) behind the door, remove it at this time. With a 5/16” nut driver remove the two self-threading screws that mount the control to the appliance, disconnect the control harness and tuck it out of the way to avoid dama

e. Using a 1 1/16” wrench and a 7/8” wrench, loosen the brass fitting on the top of the gas valve and disconnect the gas valve from the manifold inlet. This will allow you to drop the gas valve down and keep it out of the way during burner replacement. f. Using a 5/16” wrench, nut driver or screw gun bit, remove all burners by removing the (2 ea.) self threading screws holding them into the burner rack. Retain these for reinstallation of the new burners. Note: On models MG2 and SGH50, it will b

NOTE: CE approved models will have a pressure test fitting in this location. For CE approved models, remove this pressure test fitting using a 7/16” (12 mm) wrench. Using a 3/16” (5 mm) hex key, remove the plug from the auxiliary pressure tap on the manifold inlet and replace it with pressure tap fitting that you removed from the TOP (Outlet side) of the valve. Use teflon tape or apply pipe joint compound on the threads of the fitting to ensure a gas-tight seal. b. Remove the straight 1/8” NPT X

e. Thread the compression nut on the corrugated tubing end of the SCBS Valve Assembly onto the orifice assembly that you inserted into the runner tube in step c and tighten with a 1/2” (13 mm) wrench. f. Install the orifice retainer bracket onto the pilot bracket and SCBS Orifice assembly. This will secure the orifice assembly into the runner tube. g. Tighten ALL joints on the SCBS Valve assembly with a ½” (13 mm) wrench. Reinstall the pilot tubing into the gas valve. h. Reconnect the control ha

i. Connect the SCBS Harness to the SCBS Valve as shown. The red and violet wires must be connected to the vertically oriented tabs on the valve and the green (ground) wire must be connected to the bottom, horizontally oriented tab on the valve. The grey wires will be connected to the Thermal Limit at a later point in the upgrade process. j. Route the SCBS Harness along the main control harness and wire tie it to the control harness. The proper wire tie locations are indicated by arrows, see phot

appliance is in operation, or can be detected visually by watching the burner flame through the air collars. The sound of the burners will be inconsistent and the flame may appear to ‘peel’ off of the burner face. A certain amount of flame roll out during ignition is normal. However, excessive flame roll out during burner operation is abnormal. Excessive flame roll out will cause undue heating in the burner area and will cause the thermal cut out switch to trip. If there is significant flame rol
