The Mueller Professional Series 48" Freestanding Gas Range, Model No: GR-670, is a versatile cooking appliance designed for domestic use. It features a cooktop with multiple burners and a griddle, along with two ovens, offering a comprehensive solution for various cooking needs.
Function Description:
This gas range is designed for cooking, baking, broiling, and grilling. The cooktop provides six burners and a reversible griddle, allowing for simultaneous preparation of multiple dishes. The two ovens, one 1-18" conventional and one 2-30" conventional/broil, offer flexibility for different cooking tasks. The larger oven (2-30") includes both conventional and convection/broil functions, expanding its capabilities for more even cooking and faster results. The smaller oven (1-18") is a conventional oven, suitable for smaller baking or warming tasks.

- LP: Input Pressure 11 inch, Output Pressure 10 inch
The gas supply line must be equipped with an approved external gas shut-off valve located near the range in an accessible location. All connections to the gas piping must be wrench-tightened.
Electrical Power Supply Requirements:
The appliance must be electrically grounded in accordance with local codes and the National Electrical Code (ANSI/NFPA 70). It requires a 15-amp or 20-amp circuit breaker or time delay fuse.
Dimensions:
The range measures 48" in width, 28.7" in depth (excluding door handle), and 36.4" in height to the cooktop. The overall depth with the door open is approximately 44.25". Clearances require a minimum of 30" from the cooktop to the bottom of cabinets above, and 18" minimum vertical clearance between the countertop surface and combustible construction above the appliance.
Usage Features:
- Cooktop Operation: To use the burners, select the appropriate cookware and match it to the burner size. Turn the corresponding burner control knob counterclockwise to the 'IGNITE' position. You will hear a clicking noise as the spark ignites the burner. Once lit, adjust the flame by turning the knob. The outer flame of the Double Burner can be rotated to simmer (SIM) by turning the knob counterclockwise to re-ignite the outer flame.
- Griddle Operation: The reversible griddle can be placed on any of the four burner grate positions. Preheat the griddle using a low to medium flame setting. Avoid using high heat, as the cast iron properties will heat up slowly and retain heat well. Scrape grease into the grease collection trap after use.
- Oven Operation:
- Conventional Oven (1-18"): Set the temperature using the oven control knob.
- Convection Oven (2-30"): The convection fan circulates heat for more even and faster cooking.
- Broil Operation (2-30"): Place food on the second position from the top for broiling. Use a broiler pan with insert and do not use aluminum foil on a broiler pan insert.
- Anti-Tip Bracket: The range must be installed with the anti-tip bracket to prevent tipping forward, which could cause serious injury.
- Leveling: The range has 4 adjustable legs that allow for leveling to a maximum height of 39.4" (1000mm).
Maintenance Features:
- General Cleaning:
- Remove any packaging and protective films before first use.
- Clean with a solution of mild liquid dish soap and warm water.
- For stainless steel surfaces, use a non-abrasive stainless-steel cleaner and apply with a soft lint-free cloth.
- For natural luster, lightly wipe the surface with a water-dampened microfiber cloth followed by a dry polishing chamois.
- Cooktop Cleaning:
- Burner Grates: Clean with a sponge and mild solution of liquid dish soap and warm water. Dry thoroughly.
- Burner Caps and Burner Heads: Soak parts in a solution of mild liquid dish soap and warm water for 20-30 minutes, then clean with a non-abrasive sponge.
- Porcelain Cooktop: Remove burner grates, caps, and heads. Use a damp clean sponge, soft cloth, or nylon pad to wipe over the cooktop surface. Soak baked or hardened spills with a small amount of water. Do not use harsh or abrasive cleaning agents.
- Griddle Cleaning: Scrape off all food residue and cooked bits from the griddle using a non-scratch tool. Always allow the griddle to cool before handling and washing. The enamel surface develops a natural patina that will provide a non-stick surface with use. To maintain the patina, clean with a paper towel to remove excess grease and oil and wash or wipe with water. Dry thoroughly. For stubborn stains, use a paste of baking soda and water and apply with a soft brush.
- Oven Cleaning:
- Oven Racks: Remove the oven racks from the oven by sliding out. Clean with a solution of detergent and hot water.
- Oven Interior: Clean with a solution of mild liquid dish soap and warm water and a damp sponge. Do not allow excess water to run into any holes or slots in the door. Do not use oven cleaners, cleansing powders of harsh abrasives.
- Oven Gasket: Do not clean the oven gasket. The fiberglass material cannot withstand abrasion and rubbing and moving the gasket may compromise the door seal.
- Control Panel and Knobs: Clean with a solution of mild liquid dish soap and warm water and a damp cloth. Wipe in the direction of the grain. Do not use abrasive cleaners or scrubbers.
- Top Vent: The stainless-steel top vent can be removed by unscrewing. Use a non-abrasive stainless-steel cleaner to spray on any grease build up on the underside of the vent.
- Replacing Oven Light: Turn off the power at the main power supply. To prevent electrical shock or personal injury, make sure the oven and light bulb are cool and power to the oven has been turned off before replacing the light bulb. Remove the lens cover from the housing by pulling straight out then replace with a 25W appliance bulb. Make sure the lens cover is in place prior to using the oven again.
