Every electric dryer really needs an outlet whereby it expels warm, moist air, or it will not get the job done. The atmosphere is usually filled with lint, and if you don’t vent it out, it can cause all kinds of problems. The moisture can decay framing and encourage mold growth, and the lint can catch fire. The dryer vent can exit through the side or roof of your house, and the opening must be capped in a certain manner to permit the exhaust out, but maintain the elements. You need to place your dryer strategically so that you can keep the length of the vent within recommended limits.
Measure the distance from the drier to the nearest point on the house side or roof where you can install the vent cap. If it’s more than 25 feet, you may need to relocate the drier and its electrical outlet. That’s the maximum recommended length of a drier vent without a bends. Subtract 5 feet for each 90-degree and 2-1/2 feet for each 45-degree bend you need.
Make a hole for the vent cap. If you are installing a cap at the siding, trace the outline of its pipe on the ground with a pencil and cut around the outline using a reciprocating saw. The process is comparable when installing a roof vent cap, however that you need to pull shingles prior to cutting the hole and then trim and rearrange them over the vent-cap flashing.
Install the vent cap by inserting its pipe through the hole and attaching the cap to the ground or roof decking. Use 1-1/4-inch wood screws to affix the cap to siding and 1-inch galvanized roofing nails to attach it to the roof decking. The extension pipe should extend all of the way through the side of the house or the roof so you can get it from inside.
Connect a length of 4-inch rigid galvanized duct pipe to the vent cap having a pipe clamp reinforced with foil-backed duct tape. Avoid joining the pipes with screws, because screws catch lint. Tighten the clamp with a screwdriver before taping the combined.
Assemble the vent line with whatever fittings and pipes are necessary to bring it to the vent outlet on the drier. In case you’ve got a long horizontal part, then hang it in joists with duct hangers. Use shears to cut the pipe, and wear protective gloves to while cuttingdown.
Connect the port into the drier outlet with a pipe clamp. Tighten the clamp using a screwdriver and reinforce the combined with foil-backed duct tape.
