How to Pull a Range or Dryer Without Damaging the Gas or Vent

Why this matters

Cleaners pull ranges to get the grease behind them, flooring installers pull them to lay the new floor under them, and painters pull them to reach the wall. Behind a gas range is a flexible connector that was bent once, at installation, and was never designed to be bent much again. Behind a dryer is a vent that crushes when the dryer is pushed back too far, and a crushed vent turns into a lint fire risk the homeowner never sees. A freestanding range also sits on an anti-tip bracket that keeps it from falling forward onto a child standing on the open door, and it only works if the range is pushed back onto it. Moving the appliance is the easy part. This card is about the three things behind it. Why the connector is the gas trade's and nobody else's is in Appliance Gas Connectors and Why Other Trades Should Not Move Them; this card is how to move the appliance without moving the connector more than it can take.

Safety first

• Gas smell at any point: stop moving the appliance, leave it where it is, everyone out of the house, no switches, no lights, no phone used inside. Call the gas utility or 911 from outside. Do not try to close a valve you would have to reach behind a range to find.
• An old uncoated brass connector, or a connector that is stiff, cracked or kinked: do not move the appliance at all. Call the gas trade.
• Electric ranges and dryers run on 240 V: unplug only by the plug body, never the cord, and never pull an appliance so far that the cord is stretched tight against its receptacle.

The procedure

1. Look before you pull

Do it because you need to know which of the three hazards is behind this appliance before you move it an inch.

Look at the floor at the back corners for an anti-tip bracket, a small metal L screwed to the floor or wall that the rear leg slides into. Look in the drawer under the oven, or behind the range from the side with a flashlight, for a gas connector and a shutoff valve; an electric range has a heavy cord and plug instead. Gas ranges have a cord too, for the igniter and controls. On a dryer, look at the vent: a 4 in duct from the dryer's back to a wall or floor fitting. Note whether it is rigid metal, flexible metal (semi-rigid or the accordion type) or foil or plastic.

Read the connector. A coated connector has a plastic jacket, usually yellow or gray, and a tag or ring with its rating; a listed connector's tag names ANSI Z21.24 / CSA 6.10, the standard for gas appliance connectors. An uncoated brass connector is shiny or tarnished bare metal and is older; the federal Consumer Product Safety Commission has warned that their end joints can crack or separate. That is the stop in the safety block above.

What breaks if skipped: you discover the anti-tip bracket by tearing it out of the floor, or discover the brass connector by cracking it.

2. Measure how far you need to pull

Do it because a connector has a fixed length and the distance you pull is the distance it has to stretch and bend.

Decide what you need: an inch or two to slide a scraper, the full depth of the appliance to lay floor, or enough room to stand behind it. Connectors come in lengths from about 1 ft to 6 ft, and the installed one is usually the shortest that reached. If the connector is short and you need the full depth out, step 3 applies. If you only need a few inches, the connector can take that without being disturbed.

What breaks if skipped: you pull until something stops you, and the something is the connector at full stretch.

3. Close the appliance shutoff when the connector must move

Do it because if the connector is bent, stretched or flexed while it holds gas, a cracked joint leaks immediately.

Where you will move the connector beyond a gentle slide, close the appliance's own shutoff valve first: a quarter-turn handle where the connector meets the house pipe, closed when the handle is crosswise to the pipe. Only do this if you can reach it without pulling the appliance first; on most ranges you can through the bottom drawer opening. If you cannot reach it, or it does not turn by hand, stop and call the gas trade. Do not use tools on it.

Closing a valve on a range with standing pilots (older models, with a small flame always lit) puts the pilots out, and relighting them is a job for the homeowner following the label or for the gas trade, not for you. Know which kind you have before you close it.

What breaks if skipped: a connector cracked under gas has no valve between the leak and the house.

4. Slide straight, without lifting or twisting

Do it because connectors tolerate a gentle bend and do not tolerate kinks, twists or sharp angles at the fittings.

Pull the appliance straight out, square to the wall, with one person guiding the connector and the vent so neither catches. Do not lift the back of a range to clear the bracket; slide it, rocking gently if the rear leg is engaged in the bracket, so the leg comes out of the bracket without you lifting the weight. Use an appliance slide or a sheet of hardboard to protect the floor and to keep the legs from catching. Keep the connector in a gentle curve; if it starts to form a sharp bend or a loop that tightens, stop and reposition.

What breaks if skipped: a connector bent past its radius near the fitting, which is where they crack.

5. Keep the dryer vent connected and uncrushed

Do it because a vent that comes loose dumps lint and moisture into the wall cavity, and one that crushes when the dryer goes back restricts airflow until the lint catches.

If the vent pulls loose, reconnect it with its clamp before pushing the dryer back. If it is plastic, or foil with no transition-duct listing (UL 2158A) printed on it, it is not the duct the dryer's installation instructions or the IRC's dryer exhaust section M1502, as adopted, allow; tell the homeowner in writing and leave it to them to call the dryer or vent trade. When pushing back, push slowly and watch the vent fold rather than crush; leave the dryer an inch or two farther from the wall than feels natural if the vent has no room.

6. Push back, reopen, and check

Do it because this is the step that puts gas back, and the anti-tip bracket only protects anyone if the leg is in it.

Push the appliance back, guiding the connector and vent, until the rear leg slides into the anti-tip bracket. Check engagement: with the oven door closed, try to tip the range forward gently by the top at the back; it should not lift more than a fraction of an inch. Then open the gas shutoff if you closed it, slowly. Stand at the front of the range, not leaning behind it. Sniff the area behind and below. Brush a gas leak detection solution on the two connector ends if you can reach them; bubbles mean close the valve and call the gas trade. Light each burner and confirm a steady blue flame.

What breaks if skipped: a range that falls forward onto a child, or a leak that nobody looks for because the appliance is back in place.

7. Reset the anti-tip bracket if the floor changed

Do it because a bracket set for the old floor height does not hold the leg on a new one.

If you raised the floor, the bracket has to be reset on top of the new surface or on the wall plate, whichever the range's installation instructions allow. On a floating floor, mount it to the wall rather than screwing through the floor, because a screw pins the floor and stops it moving.

A worked example: a kitchen and laundry floor

A flooring crew is laying a click-lock floating floor through a kitchen and laundry room. The new floor plus its underlayment is 9 mm, just under 3/8 in, on top of the old vinyl.

Range, step 1. Gas range, standing pilot on the oven only (electronic igniters for the cooktop). Coated yellow connector visible through the drawer opening. Anti-tip bracket screwed to the floor at the back left. Electric cord for the igniters.

Range, step 2. The range is 25 in deep and the floor has to go all the way to the wall, so the crew lays the open kitchen first and then needs the range clear of its alcove: about 30 in of travel, more than a gentle slide. The connector looks to be about 4 ft long, in a loose loop behind.

Range, step 3. The shutoff is reachable through the drawer opening. The crew closes it, crosswise to the pipe. That puts the oven pilot out; the crew notes it and tells the homeowner they will need to relight it per the label, or call the gas trade.

Range, step 4. Two people slide it out onto hardboard laid over the new floor, one guiding the connector, and unplug the cord once the plug is reachable. At 30 in the connector is still a gentle curve with slack, so they stop there and lay the alcove. Had it straightened first, they would have stopped short and called the gas trade rather than gain the last few inches.

Range, step 7. The old bracket is screwed to the old floor, so once the new floor is down its hook would sit about 3/8 in below the surface the leg stands on. The crew removes the bracket before laying the floor and, after the floor is down, remounts it to the wall plate as the range's instructions allow, at the height for the new floor.

Range, step 6. Range pushed back, leg in the bracket, tip test holds. Gas opened slowly, no smell, leak solution on both connector ends shows no bubbles. Cooktop burners all light blue. Oven pilot left for the homeowner, who relights it while the crew is still there.

Dryer, step 1 and 5. Electric dryer, foil vent. The dryer comes out on its 240 V cord, which has enough slack. The foil vent pulls loose at the wall fitting. The crew reconnects the foil with its clamp so the dryer can run, and writes a note to the homeowner: the vent is foil with no listing printed on it, the dryer's manual and the code call for metal duct or a listed transition duct, and a vent or dryer trade should replace it.

Result. Two appliances out and back, the connector never at full stretch, the bracket reset for the new floor, a leak check done at the step that put gas back, and the foil vent handed to the trade that owns it in writing.

What would change the call

• The range must come all the way out and the connector will not reach: the gas trade disconnects and reconnects it, or replaces it with a longer one. You do not.
• A stiff, old or kinked connector: do not move the appliance; the gas trade replaces the connector first.
• A gas dryer: steps 3 and 6 apply to it the same way as to a range; a gas dryer also has a connector and a shutoff behind it.

How to know you got it right

The connector was never at full stretch or kinked, the shutoff is back open with no odor and no bubbles, every burner lights, the range passes the tip test, and the dryer vent is connected and uncrushed or written up.
