How to install a tumble dryer vent hose
A vented tumble dryer pushes warm, damp, lint-laden air out through a flexible hose. The hose must reach outside, through a wall vent or a window kit, as short and straight as you can make it. A long, kinked or crushed hose makes drying slow and lets lint build up.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Flexible vent hose
- Hose adaptor for the dryer outlet
- Hose clips
- Wall vent or window vent kit
Step by step
Step 1: Unplug the dryer and pull it out far enough to reach the outlet on the back.
Step 2: Measure the shortest route from the outlet to the wall vent or window and cut the hose to that length plus a little slack, with no loops.
Step 3: Push the adaptor onto the dryer outlet and fit the hose over it, holding it with a hose clip.
Step 4: Fit the other end over the wall vent spigot or window kit and clip it; the flap on the outside vent should open freely when air blows.
Step 5: Push the dryer back slowly, watching that the hose is not squashed flat against the wall or bent into a sharp kink.
Step 6: Plug in and run the dryer briefly on heat, then check warm air is coming out of the outside vent and not at the joints.
Step 7: Clean the lint filter after every load and check the hose for lint build-up every few months.
Common mistakes
- Venting into a cupboard, loft or wall cavity instead of outside.
- Using a hose far longer than needed, coiled behind the dryer.
- Taping joints with ordinary tape that dries out and falls off.
Safety notes
- Lint is flammable; never run the dryer without the lint filter or with a blocked hose.
- Do not vent into a chimney or a flue used by a gas appliance.
- Cutting a new hole through an outside wall may need a builder; check local rules.
