Wolf GR Series - User Manual

The Wolf Gas Range (GR) Series is a domestic cooking appliance designed for use with either natural gas or liquid propane (LP) gas. It features an electrical ignition system and is certified by the Canadian Standards Association (CSA) for both gas types. The range requires a regulated gas supply and a 110-120 V AC, 60 Hz electrical supply with a 15 amp circuit breaker for its ignition system. It is equipped with an anti-tip device for safety, which must be properly installed and engaged. The oven door(s) can be removed for easier installation or to lighten the load, and the range has rear casters and adjustable front legs for leveling.

Usage Features:

Gas Shut-Off Valve: An approved external gas shut-off valve must be located near the range in an accessible location.
Oven Door Removal: For easier movement or to lighten the load, oven doors can be removed by a certified installer or service technician. Hinge pins, located inside the oven door, are inserted into the appropriate hinge(s) to facilitate removal. For single oven ranges, the pin goes into the right hinge; for double oven ranges, pins go into the outer two hinges.
Leveling: The range can be leveled by adjusting the front legs (rotating clockwise to raise, counterclockwise to lower) and rear casters (rotating clockwise to raise, counterclockwise to lower). A long sturdy screwdriver or bar can be used for fine adjustments of the rear wheel assembly.

Maintenance Features:

Leak Testing: All gas connections must be tested for leaks using a brush and liquid detergent. Bubbles indicate a leak, requiring the gas valve to be shut off and connections adjusted. Open flames must never be used for leak detection. The detergent solution should be cleaned from the range after testing.
Anti-Tip Bracket Installation: The anti-tip bracket is a crucial safety feature. It must be properly positioned 3" (76 mm) from the left side of the opening and secured to the wall or floor.
- Drywall Application: Mark holes, drive wall anchors flush, and fasten the bracket with #8 screws and flat washers. Pre-drilling may be needed, using a 1/4" drill bit for hard wallboard/double-board or a 7/16" drill bit for solid plaster.
- Wood Floor Application: Drill 3/16" (5 mm) pilot holes and secure the bracket with #12 screws and flat washers.
- Concrete Floor Application: Drill 3/8" (10 mm) holes at least 1-1/2" (38 mm) deep and secure the bracket with 3/8" wedge anchors.
Anti-Tip Bolt Adjustment: Once the anti-tip bracket is secure and the range is leveled, the anti-tip bolt should be adjusted so the top of the washer is a maximum of 7/8" (22 mm) from the floor. The range is then slid into the opening, ensuring the anti-tip bolt engages the bracket.
General Maintenance: The document emphasizes that additional installation information can be found in the installation guide or by contacting the Wolf Appliance Customer Service Department. It also states that service technicians should be familiar with these installation issues.
