Step 12. RE-INSTALL FRONT GLASS ENCLOSURE PANEL

(Reverse instructions on Step 4)

Retrieve the front glass enclosure panel. Visually inspect the gasket on the backside of the frame. Gasket surface must be clean, free of irregularities and seated Þrmly.

With the stove top off, position the glass front enclosure panel into the front opening with the gasket facing the relief door (reference Figure 8 & 9). Let the bottom of the door frame gently slide down, then hook the top ßange of the glass frame over the top of the Þrebox frame.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Fasten the two latches located beneath the Þrebox ßoor to the glass frame vee-ßange. Close both the latches securely.

Step 13. TEST ALL CONNECTIONS FOR

LEAKS (FACTORY AND FIELD).

Test For Gas Leaks

A. Mix a 50% dish soap, 50% water solu- tion.

B. Light the appliance (refer to the lighting instructions provided in the Homeowner's Care and Operation Instructions).

C. Brush all joints and connections with the soapy water solution to check for leaks. If bubbles are formed, or gas odor is detected, turn the gas control knob to the ÒOFFÓ position and close the gas shut-off valve. Either tighten or refasten the leaking connection and retest as described above.

D. When the gas lines are tested and leak free, observe the individual tongues of ßame on the burner. Make sure all ports are open and producing ßame evenly across the burner. If any ports are blocked, or partially blocked, turn off unit, allow it to cool, then clean out the ports.

Turn on gas supply and test for gas leaks using a soapy water solution. Never use an open ßame to check for leaks.

Step 14. CHECKING APPLIANCE OPERA-

TION

With gas line installed run initial system checkout before closing up the front of the unit. Follow the pilot lighting instructions provided in the Homeowner's Care and Operation Instructions (or pull out the instruction label located in a holder on rear shield of stove) .
