Gas Fitting · Appliance Hook-UpGas Stove & Range Installation
Gas stove and range installation is a licensed connection, not a delivery add-on: a TSSA-licensed gas technician fits a shut-off valve in the same room, a new certified flexible connector that stays entirely behind the range, leak-tests every joint and anchors the anti-tip bracket. If a capped gas stub and a 120-volt receptacle are already behind the range, the hook-up is a single visit of an hour or two. If either is missing, a gas branch or an electrician comes first.
The connection has four parts and each has a rule. The shut-off valve sits in the kitchen, where you can get at it, not in the basement below. The connector is a certified appliance connector, new with the range, and it may not pass through a wall, floor or ceiling; that part of the route has to be rigid pipe or tubing. Every joint is checked with leak-detection solution with the gas on, and the anti-tip bracket shipped with the range gets screwed to the floor or wall so an open oven door cannot lever the range forward.
Most ranges leave the factory set for natural gas with a propane conversion kit in the box. Propane arrives at higher pressure and carries more energy per volume, so it needs smaller orifices at every burner, a different oven and broiler setting and the appliance regulator switched over. On rural lots in Kilbride, Lowville, Campbellville, Carlisle and rural Caledon, where gas mains do not reach, that conversion is part of the installation. A range that was converted for a cottage or bought used may arrive set for the wrong fuel, so we read the conversion label beside the rating plate before lighting anything.
Switching from an electric range means two trades. The gas branch usually ties in at the basement trunk below the kitchen, and whether the existing piping can carry it is a load question: a 30-inch range is a modest load, while a 48-inch professional-style range can draw more than the furnace. An all-gas range plugs into an ordinary 120-volt receptacle for its igniters and controls, which the old 240-volt stove outlet cannot supply as it stands. A dual-fuel range, gas on top and electric oven below, still needs a 240-volt circuit sized to its nameplate, so the old stove circuit may stay in service.
Running the pipe to the kitchen is a separate job with its own page: gas line installation covers range, barbecue and garage runs, and this page covers the appliance hook-up at the end of it. Ventilation deserves a thought at the same time, because a powerful hood over a large range can pull a naturally vented water heater's exhaust back down its flue; range hood make-up air explains when replacement air is needed. Many condo towers have no gas to the suites at all, so check with the property manager before ordering the range.
Call for a gas range hook-up when
- A new gas or dual-fuel range is being delivered and the store's crew will not connect it
- You are replacing an old range and the connector or shut-off valve behind it is original
- The kitchen is changing from electric to gas and needs a branch, a valve and a receptacle
- The range is set up for natural gas and the house is on propane, or the reverse
- A range was pulled out for flooring or cabinets and has to be reconnected and leak-tested
How it works
We confirm the fuel, the gas stub location, the receptacle and the clearances to cabinets and combustibles in the manufacturer's manual. If the branch or circuit is missing, you know before the range is sitting in the hallway.
Valve and new connector fitted, range regulator and orifices set for your fuel, anti-tip bracket anchored and the range levelled. The old connector goes in the scrap bin, not back on.
Joints are leak-tested, each burner and the oven are lit and the flames checked on high and on simmer. You are shown the shut-off valve before we leave; to arrange a hook-up, book through the contact page.
Common questions
Can the appliance delivery crew connect my gas range?
Only if the person making the connection holds a TSSA gas technician certificate, which most delivery crews do not. In Ontario, connecting a gas appliance is regulated fuel work even though it looks like tightening two fittings. Ask for the licence class and number; how to verify a TSSA licence shows where to check it.
Can I reuse the flexible connector from my old stove?
No. Connectors are made to be installed once: the corrugated metal work-hardens as the range is pushed in and pulled out, and the flared ends deform against the old fittings. Manufacturers call for a new connector with each installation, and old uncoated brass connectors should be replaced on sight. A new one is a small part of the job.
Does a gas range need its own electrical circuit?
An all-gas range needs a grounded 120-volt receptacle for the igniters, clock and oven controls; check the manual for whether it must be dedicated. A dual-fuel range needs 240 volts for the electric oven. New or altered wiring is work for a licensed electrical contractor with an ESA permit, and we coordinate our visit with theirs.
Why are the flames on my new range yellow?
On a new installation, yellow tips usually mean the range is set for the wrong fuel or the air shutters need adjusting. Natural-gas orifices fed with propane give tall, sooty yellow flames; propane orifices fed with natural gas give weak ones. Turn it off and have the setup checked, because soot means incomplete combustion and carbon monoxide.
Will my existing gas line handle a bigger range?
A standard 30-inch range on a half-inch branch is rarely a problem. A 36- or 48-inch range with six burners, a griddle and two ovens can need a larger branch, depending on its length and what else shares the pipe. We check the rating plate against the pipe size; if it falls short, a gas line upgrade comes first.
