The 4-inch aluminum-foil or white plastic exhaust ducting is very easy to install. The hose-like product’s spiraled wire interior is strong and flexible, and it costs between 50 cents and $1 per foot. However, ducting is not the best option. It can’t exhaust hot air well and in certain cases it can even be dangerous.
The pipes’ ribbed and corrugated surfaces act like speed bumps that slow down the airflow. Drying clothes takes more time, which is a waste of energy and money. The dryer’s interior also traps lint. This reduces airflow, and can overload the motor in extreme cases.
A buildup of lint can cause fire hazards. A lint fire in a gas dryer can melt plastic ducting and ignite a fire. It is prohibited by building codes and owners manuals.
Which Dryer Vent Hose is Best?
Installing a rigid-metal exhaust pipe is the solution. The dryer’s smooth interior reduces air resistance and discourages lint buildup. A 8-foot-long flex hose made of plastic was replaced with a smooth-metal vent. This reduced drying time by 10 minutes for a full load. This is how it happened.
Dryer Vent Installation in 6 Steps
Step 1: Remove the dryer from the wall
- The dryer should be pulled away from the wall. Next, disconnect the power cord. If the dryer is gas-fired make sure you close the gas valve.
- Next, remove the band clamp holding the plastic vent to exhaust outlet.
- Take the outlet from the dryer and vacuum any lint.
- Next, disconnect the plastic vent at the end that connects to the ducting outside.
- Use a vacuum to remove lint from the round duct.
Step 2: Secure the clamp
- Place a clamp made of metal over the lower end the periscope box vent, and then press it on the exhaust outlet.
- Keep the vent steady and tighten the clamp using a screwdriver.
Step 3: Attach your periscope
- Grab the upper portion of the periscope, and lift it up until it reaches the dryer’s back.
- Plug the power cord and turn the gas back on if necessary. Then push the dryer against the wall.
Step 4: Connect the dryer vent kit to the box vent to the duct
- The only thing left is to connect the box vent with the overhead duct using the vent kit.
- Attach the lower flex vent first to the periscope vent.
- Use a band clamp to secure the elbow.
Step 5: Attach a 90° elbow
- Next, slip a band clamp onto an overhead duct. Insert the male end from the 90-degree elbow in the duct. Finally, tighten the clamp.
Step 6: Connect your devices
- Next, grab the lower flexvent and pull down on the upper vent. The two vents will meet halfway between the ceiling and dryer.
- The vents’ ends have quick-lock fittings which snap together without the use of a band clamp.
Once you have made all the connections, it is time to test the new vent system. Check that the dryer is on and that the airflow is good through the vent hood mounted outside your home.
