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.

Tools needed

  • Cross-head screwdriver
  • Tape measure
  • Scissors or snips for the hose

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

  1. Step 1: Unplug the dryer and pull it out far enough to reach the outlet on the back.

  2. 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.

  3. Step 3: Push the adaptor onto the dryer outlet and fit the hose over it, holding it with a hose clip.

  4. 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.

  5. Step 5: Push the dryer back slowly, watching that the hose is not squashed flat against the wall or bent into a sharp kink.

  6. 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.

  7. 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.

This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
