Ranges & Ovens installation: the cord, the connector, the bracket.
An electric range is a dryer's install at a bigger size: a 240V cord that is never in the box, wired to a terminal block that must match the outlet. A gas range adds the one connection on this site we do not describe as a home job — the flex connector, the shutoff and the leak check belong to a licensed installer. Both kinds share the anti-tip bracket, which every maker ships for and every install must use.
First use: what is normal
A new machine can do things on its first run that look like a fault and are not. Here is what the makers say is normal, what to do first, and where the line is.
Normal the first time
- Smoke and a strong smell on the first heat. Factory oils, the protective coating and the insulation are burning in. It fades after the first few uses.
- Fans that keep running, even after the oven is off, along with clicks and hums as the parts heat up and cool down.
- On a gas oven, a brief whiff of gas when it lights, gone in the first few minutes of preheating.
Do this first
- 1Remove all packing first: film, cardboard, zip ties and anything left inside the oven.
- 2Before you cook, run it empty at 350 to 500 degrees for 45 to 60 minutes with a window open. The makers' numbers differ inside that range. If the smell is still strong, run it once or twice more.
- 3Keep pet birds out of the room: the fumes can kill some birds.
- 4Wipe it out with a damp cloth once it cools, and keep foil off the oven bottom.
Where the line is. Smoke or a burning smell that stays after the burn-in, a gas smell that stays, or a fan that rubs or scrapes is never normal: stop using it and text us. A rotten-egg smell or a hissing sound: leave the house, then call the gas company or 911 from outside.
What is typically not in the box
Surplus inventory — open box, cancelled order, overstock, minor scratch & dent — is priced for exactly this: a unit can arrive without the small items that ship with a sealed machine. Have these on hand before install day.
The power cord on an electric range — a 40 or 50 amp 3-wire (NEMA 10-50) or 4-wire (NEMA 14-50) range cord KIT, matched to the outlet.
The flexible gas connector and the shutoff valve on a gas range, where the house has none; the LP conversion kit if the range runs on propane (often in a bag taped inside, often not on a surplus unit).
The anti-tip bracket on a surplus unit, occasionally — a universal bracket is sold separately and the manual gives the template.
Oven racks, the broiler pan, the griddle or wok ring — check inside.
The printed manual — download it by model number.
Power, water, gas, venting, space
What the room has to have before the appliance comes through the door. The manual gives the exact figures for your model; these are the shapes to check.
A dedicated 240V, 40 or 50 amp circuit (the plate says which) with a 4-slot NEMA 14-50R in a home wired since 1996 or an older 3-slot 10-50R where that circuit remains. The cord matches the outlet; the terminal block is wired to match the cord.
A grounded 120V outlet for the igniters, clock and lights, and a 1/2-inch gas line with a shutoff valve in the same room. Natural gas or propane: the range is built for one and converted to the other with the maker's kit by the installer.
Required on every freestanding and slide-in range (UL 858): a bracket screwed to the floor or wall that a rear leveling leg slides under, so the range cannot tip when the oven door is open with weight on it. The install is not finished until the bracket is engaged.
A standard range is 30 inches wide; the opening needs the manual's inch or so of side clearance and the cabinet clearances above a cooktop. A slide-in sits on the countertop lip; a freestanding stands free.
A hood or an over-the-range microwave above it at the manual's height. A gas range in particular wants a hood that vents outside.
The install, step by step
An overview of the manufacturer's own sequence, so you know what a good install looks like whether you watch one or do one. The manual's page for your model is the authority on every figure.
- 1
Electric: match the cord to the outlet and wire the block
Three slots means a 3-wire cord, four means a 4-wire. Behind the small plate on the back: the outer terminals take the two hot wires, the middle takes the neutral; a 4-wire cord's green wire goes to the ground screw and the bonding strap is removed, a 3-wire cord leaves the strap in place. Strain relief fitted, cover on.
- 2
Gas: the installer connects it
A new listed flexible connector between the shutoff and the range's inlet (never reused, never kinked, never run through the floor), pipe-thread sealant on the rigid threads only, then a leak check with a soap solution at every joint with the gas on. Propane: the conversion kit installed and the regulator set before the first flame.
- 3
Fit the anti-tip bracket
Mark the bracket's position with the manual's template, screw it into the floor or the wall framing, and slide the range in so the rear leg engages it. Tip the front of the range gently to confirm it catches.
- 4
Level it
A level on the top and on a rack in the oven; the leveling legs set so the oven bakes level and the doors line up with the cabinets.
- 5
Run the first heat
Remove all packing, then run the oven empty at 350–500°F for 45 to 60 minutes with a window open and pet birds out of the room — a new oven smokes and smells on its first heat, and that is the factory oils and coating burning in, not a fault. Light each burner; a gas burner's flame should be blue with small yellow tips at most.
- 6
Check the clock, the lights and the door
Set the clock, confirm the oven light and the interior fan, open and close the door and the warming drawer. Anything that needs attention is reported the same day.

Drawn by us, schematic on purpose: the shape of the connection with every part named. Your model's wiring and hookup page in the manual rules on the details.
Mistakes that look like a broken machine
Most first-week calls are one of these. Each is an install item, not a fault — and each is the reason we ask for every function to be tested before the installer leaves.
The range cord wired with a hot leg on the neutral post — the burners work and the oven does not, or the breaker trips.
The anti-tip bracket skipped — a range that tips forward with the door open is the one oven accident the standard exists to prevent.
A gas connector reused from the old range — connectors are one-use; an old one is the leak.
A propane house and a natural-gas range not converted — large yellow flames and soot on the first day.
The first heat judged by the smell — a new oven smokes and smells on its first heat; it is the factory oils and coating burning in.
When a licensed installer is the standard
We recommend professional installation for every appliance we sell. On a ranges & oven these are the parts of the job that the code, the permit or the manufacturer's warranty place with a licensed trade.
Every gas range connection — the connector, the shutoff, the conversion and the leak check — is a licensed gas fitter's or plumber's job under the fuel-gas code.
A new 240V 50-amp receptacle or any panel work is a licensed electrician's job.
A wall oven is hardwired into a junction box by an electrician and built into the cabinet by an installer; a slide-in with a downdraft needs its duct run.
Asked at the counter
Does the range come with a cord?
An electric range does not — the 40 or 50 amp cord depends on your outlet and is sold as a kit. A gas range's 120V cord is attached at the factory.
My house has propane. Can I use a natural-gas range?
Yes, after the maker's LP conversion kit is installed and the regulator set — a job for the licensed installer at install time. A range run on the wrong gas has large yellow flames and soots the pots.
What is the anti-tip bracket and do I really need it?
A bracket on the floor or wall that the rear leg slides under so the range cannot tip forward with the oven door open. Every maker requires it, the standard (UL 858) requires it, and an installer will not sign off without it.
The oven smells on the first use.
The first heat burns in the factory oils and coating; run it empty at 350–500°F for 45 to 60 minutes with a window open. A smell that is burning plastic or electrical, a gas smell that stays, or a fan that rubs or scrapes is different — shut it off and text us.
What your receipt says about installation
Installation & testing
Apex Sales does not perform installation, and we strongly recommend professional installation. Moving or installing an appliance without the proper steps — transported upright and secured, every connection checked, and the unit leveled — can loosen parts or cause problems, and improper installation can void the manufacturer warranty. Have a licensed plumber, electrician, or appliance installer test every function of the unit before they leave, so any issue can be reported right away. Damage caused by improper installation is not covered.
Condition & warranty
All units are surplus inventory (open box, cancelled order, customer return, overstock, or minor scratch & dent). Every unit includes the manufacturer's full factory warranty. Please inspect thoroughly in person before purchasing — cosmetic imperfections or missing accessories are possible.
These pages are a general reference for the appliances we sell. They do not replace the manufacturer's installation instructions, the local building, electrical, plumbing, gas and mechanical codes, or the judgment of a licensed installer. Apex Sales does not perform installations and is not responsible for installation performed by the customer or by a third party. Damage caused by improper installation, transport or connection is not covered by the manufacturer's warranty or by Apex Sales.
When it's not a DIY moment
Everything on these pages is safe to look at with the machine unplugged or the gas shut off. These three are not a look — secure the appliance and call.
Gas smell
Close the appliance's shutoff valve if you can reach it safely, open a window, leave the room, and call the gas utility from outside. No switches, no flames.
Burnt smell, a melted plug, arcing
Shut the breaker off, not just the appliance. A scorched cord, plug or outlet means an electrician looks before anything is plugged back in.
Water that will not stop
Close the supply valve at the appliance first (washer, dishwasher, fridge line, water heater cold inlet), then unplug. Mop before you diagnose.
Text us the model number and what it's doing — we'll point you at the next step.
A fix, a part, or a warranty call — the plate's model and serial plus one line about the symptom is all it takes to tell which.
These pages are educational. Every appliance is a little different — follow the manufacturer's manual and local code, and leave gas, water heater and 240V work to a licensed installer.
