Gas range installation requirements describe the gas supply line, connector, shutoff valve and fuel setting a range needs, plus its 120-volt outlet for the igniters, clock and oven controls. They're in the guide because the range's regulator and burners are built for a set gas type and pressure, and anyone using or servicing the range needs a way to shut the gas off quickly.
What the spec actually says
The figures below come from Amana's guides for the AGR4230BA, a 30-inch freestanding gas range.
- •Supply and connector: The guide says to provide a gas supply line of 3/4-inch rigid pipe to the range location, with 1/2 inch as the minimum on LP gas. The range's pressure regulator takes a 1/2-inch male pipe thread. If local codes permit, a new CSA design-certified flexible metal connector, 4 to 5 feet long with a 1/2- or 3/4-inch inside diameter, may be used.
- •Shutoff valve: The supply line must have a manual shutoff valve located in the same room but outside the range opening, such as in an adjacent cabinet.
- •Fuel type: The range is factory set for natural gas, and conversion to LP must be done by a qualified service technician.
- •Power: A 120-volt, 15-amp circuit is required, a separate circuit is recommended, and the cord's three-prong plug goes into a grounded outlet.
- •Joints and pipe size: A later revision of the same guide adds that pipe-joint compounds that resist LP gas must be used, not Teflon tape, and that a smaller pipe on a longer run may not supply enough gas.
Why manufacturers require it
- •Enough gas: A range with several burners and an oven running needs a steady volume of gas. Undersized pipe on a long run can leave burners weak when everything is on.
- •The regulator: It holds gas pressure steady at the burners. Its inlet thread and the connector size have to match.
- •A reachable shutoff: A valve behind the range is hard to reach in an emergency. The guide's placement, outside the range opening, lets you close it without pulling the range out.
- •New connectors: Flexible connectors can crack or corrode after being bent during earlier moves. A new, certified connector avoids that.
- •Fuel setting: Natural gas and LP need different orifices and regulator settings. The wrong one gives yellow, sooty or oversized flames.
How to check your home against it
Visual checks only. Don't loosen any fitting or work on the gas line.
- Find the rating plate. On the AGR4230BA, it's on the oven frame behind the top left of the oven door. Confirm the gas type.
- Look for the shutoff valve. Check the cabinet beside the range first, then behind the range or in the drawer space.
- Look at the connector. It should be a flexible appliance connector in good condition, not kinked, crushed or corroded.
- Confirm the range plugs into a grounded three-prong outlet with no adapter.
- Check that the range is level, following the leveling steps in its installation instructions. The guide says the cooktop isn't a reliable reference.
- If the range came with an anti-tip bracket, check that the range is engaged in it, as its installation instructions describe.
What happens when it's ignored
- •Burners run weak or uneven when several are on, from an undersized supply.
- •The wrong fuel setting produces yellow flames, soot and odors.
- •A shutoff hidden behind the range can't be closed quickly.
- •An old or kinked connector can leak.
- •An unlevel range bakes unevenly and lets pans slide.
The cabinets above and beside a gas range have their own clearances. See range clearance to cabinets.
When it needs a licensed pro
- •Connecting or disconnecting a gas range, replacing a connector, or adding a shutoff valve is work for a licensed gas fitter or plumber, as your town requires.
- •LP conversion must be done by a qualified service technician, per the guide.
- •If you smell gas, National Grid says to go outside and call 1-800-490-0045 or 911 immediately, and not to touch switches, phones or plugs on the way out.

Quick check: Find your range's gas shutoff before you need it. If you have to pull the range out to reach it, ask a gas fitter about moving it.
