A summary of the typical codes relating the dryer venting is as follows: Dryer vent systems shall be independent of all other systems and shall convey the moisture to the outdoors. Terminations shall be a minimum of three feet from property line and 12" above the ground and not exhibit any type of screen.
M1502.
The maximum developed length of a clothes dryer exhaust duct shall not exceed 35 feet from the dryer location to the wall or roof termination. The maximum length of the duct shall be reduced 2.5 feet for each 45-degree (0.8 rad) bend, and 5 feet for each 90-degree (1.6 rad) bend.
At the terminating end of the exhaust duct (at the exterior wall), install a backdraft damper. The hood opening should point down and should be at least 12 inches above the ground (Cranor 2005). A louvered damper is more effective than a single hinged door. No screen should be installed in the duct terminus.
It's a 4 inch vent. It ranges from about 41.5 inches to 45.5 inches, give or take a quarter of an inch.
How high up should a vent be installed for my tumble dryer? This depends on your manufacturer. Check your product manual to find out. It's also handy to know that your vent hose should always be level or vented downwards to stop condensation building in the dryer.

Air-vented dryers draw air from the room in which they are installed, heat it and lead it through the humid clothing in the drum to evaporate the moisture. The humid air is then expelled to the external environment. Air-vented dryers thus require an exhaust to the outside, making them less practical.
Yes, that's considered safe. The operating temperature of a dryer vent is not a problem for direct wood contact. Keep the vent clear and you'll have no fire. Ensure all joints are foil taped, so lint does not escape from the pipe.
The most common place to vent your dryer is horizontally through the exterior wall near the dryer, which is the ideal placement. Other common locations are through (but not into) the basement or the attic/roof. For most dryer models, you can't run the exhaust duct more than 25 feet from the dryer to the exhaust port.
Vents shall terminate not less than 5 feet (1524 mm) in vertical height above the highest connected appliance flue collar. Exceptions: Venting systems of direct vent appliances shall be installed in accordance with the appliance and the vent manufacturer's instructions.
12” to 48” inches is a typical height for a dryer outlet.
Your dryer should be mounted at a minimum distance of 250mm to the ceiling, and 1320mm distance to the floor. If you are mounting your dryer upside down, you may need to invert the control buttons using a screwdriver. Your dryer's instruction book should have some pointers.
Duct vents at exterior should be a minimum of 3 feet from any other opening; window, door, other vents, etc. Duct vents at exterior should be at least 6 feet from the A/C condensing unit. Duct vents should never be terminated in the attic or crawlspace. Never combine dryer venting with any other venting source.
Some dryers can exhaust beyond 25 equivalent feet without a booster fan. Dryer Duct Booster Saves significant energy - reduces drying times 50% or more. Reduces lint build-up, dust & fire hazards by maintaining proper velocity in duct runs up to 150 equivalent feet.
When installing a dryer vent for laundry centers in basement locations, the vent hood on your home's exterior must be at least 12 inches from the ground. A dryer duct should be 25 feet or less.
People are always asking what type of duct pipe can be used to vent a dryer in a 2x4 wall. We have the answer from our resident expert. You can use a standard 4" snap lock. It just gets compressed in a 2X4 wall (3.5" deep).
Fire Safety: Speaking of fire risk, a hard pipe is also safer than flexible accordion piping. The ridges and creases in flexible piping can trap lint and other debris, which can quickly accumulate and become a fire hazard.
Long vertical runs can result in greater humidity and lint accumulation, which will reduce drying efficiency. Vertical runs may require the installation of a booster fan to maintain effective exhaust air flow.
Close vent offsets between dryer and wall vent located on same wall as dryer (Offsets between 6-9 inches): The MV-90 can be coupled directly to a standard 4 inch diameter, adjustable, 90 degree elbow which creates a 9 inch offset.
Typically dryer vents/Exhaust terminations should be terminated at least 12" above finished grade to prevent this issue.
Improper venting of a dryer typically results in moisture being deposited in various areas of the room. Moist air serves as a breeding ground for mold-and-mildew when it condenses on different surfaces. You want to exhaust the warm air outside the home rather than indoors to properly vent your dryer.
Condenser Tumble Dryer
condenser tumble dryers are the more popular type of tumble dryer. These appliances do not have a vent to expel moisture. The hot air is moved to a tank or a reservoir where the moisture is condensed into water (vapour to liquid) usually under the machine.
The average lifespan of a tumble dryer
On average a tumble dryer should last 10 to 15 years. This depends on factors such as maintenance, ventilation, and quality.
