It has become a personal goal of mine to place an Almetal ® Dryer Vent in as many homes as possible. We could save energy and make our homes safer in the process. Our dryer vent pays for itself in a short time with the energy savings alone.  Most people do not realize that their clothes dryer is one of the highest energy using appliances in their home. If you want to cut your energy bills and be GREEN, then vent your clothes dryer the correct way. 

A great deal of time and work has gone into giving you the best product information and installation methods that I can. While the task of installing The Almetal Dryer Vent may be easy for many who have the tools and items necessary to install your vent correctly and safely, others may need to call their handyman of choice. HVAC Contractors normally are familiar with dryer vents. What ever your case may be, you should find the following very informative.

Facts about Clothes Dryers

Have you read the use and care guide that came with your dryer? Are you following the manufacturer’s recommended procedures for proper installation and use? If you have read this guide, you already know that all manufacturers state not to use plastic flexible hose to vent your dryer. In fact, the largest manufacturer of clothes dryers in the world voids their warranty if their dryer is vented with plastic flexible hose, and yet plastic flexible hose is still in use in the majority of homes today and continues to be used in much new construction. We at the Almetal ® Dryer Vent Company provide a way to meet the dryer manufacturers’ recommendations and we go one step further. The Almetal ® Dryer Vent eliminates all flexible hoses and vents your dryer the safest and most efficient way. It also adds the convenient benefit of allowing you to easily slide your dryer out for cleaning behind it -- without requiring tools to unattach and reattach hoses.

Clothes Dryers are one of the most expensive appliances in your home to operate. The longer it runs, the more money it costs you. The way a dryer works is really quite simple. Hot air is forced through a turning drum. Wet clothes are placed in the drum and are dried by the hot air. A full load of wet clothes may contain one to one and a half gallons of water. As that water is removed, lint is created from the clothes. Much of this lint is trapped in the dryer’s lint filter, which should be cleaned after every use as stated in your dryer’s care and use guide. However, lint filters do not trap or catch all lint. The lint that remains is carried through your vent system along with moist air.

 A Consumer Note.

In my opinion, after venting over 3,000 clothes dryers, I have found that all dryers work the same. The point being. In todays market place, when you want to purchase a new clothes dryer, it can be confusing. The prices and models vary  from the bottom to the top. You can pay $ 350.00 or well over $ 2,000.00 for dryers that perform the same way. The major difference being their capicity, the rest are for marketing.  All clothes dryers work and vent basically the same. Some dryers do have more air flow (CFM) than others, but very few manufacturers use that information in their marketing efforts. In summary,  if you want a metal flake shinny red front loading dryer, then go buy it. You will pay some where around $ 2,000.00. But remember, you could buy a $ 500.00 model that would dry your clothes just as good and as quickly.  As for the new steamers, I think it is another marketing gimmick. The hose is in the wrong place and it is another hose to break and cause water problems. As far as consumer reports findings, the last time we checked the "Whirlpool Cabrio" model was rated at the top.  


Flexible hoses create air turbulence, which is resistance to efficient air flow. In some cases, the dryer may be installed in a way that pinches the hose and restricts airflow dramatically. Moisture collects on the pleats of all flexible hoses and lint can easily stick to these surfaces and cause lint to build up and create a fire hazard. This also causes your dryer to work harder, costing you in service calls and cutting short the life of your dryer. In replacing short runs of flex duct behind dryers that connect it to the rear or side wall, less than 30", drying times are cut by 10 to 20 minutes. Hard to beleive, but true.

There are over 30,000,000 clothes dryers in the United States. If every dryer in America could save just 10 minutes on every load of clothes, we could close power plants and reduce the carbon foot print significantly.



The key to efficient and safe clothes drying is to create an efficient vent system to move lint and moist air together with as little resistance as possible. The Almetal ® Dryer Vent Company has developed a method and product that eliminates the need for any flexible hoses and reduce the resistance to air flow. This prevents a fire hazard while saving you energy, time, and money.

The Basics of Installation
The exhaust pipe extender is installed on the dryer. The periscope and receiver are positioned and installed directly behind the dryer. The dryer is moved back into place, such that the exhaust pipe extender slides tightly into the receiver.

Avoid frustration - Read through the entire Installation Procedure before beginning.

Tools Needed  
Tape Measure  
Tin Snips  
Reciprocating Saw (if it is necessary to cut floor)  

Other Items That You May Need: (available at most hardware stores)
adjustable elbows
4" aluminum piping
additional metal foil tape


Installation Tips

If the periscope is too long, it can be pulled apart and shortened by cutting the ends back using tin snips. Be sure to allow for some overlap when you reassemble the pieces and file rough edges so they will not catch lint.  Don't substitute a hacksaw for tin snips. It will not work well.

Use metal foil tape on the ends of the periscope to seal any cracks.  Air leakage disrupts the efficient flow of air and can allow lint buildup.

Never use screws to fasten pieces together. Screws or rivets project into the airway and will catch lint.

We recommend two layers of metal tape on all joints. Always use metal foil tape. Duct tape will deteriorate with time.

Minimize 90-degree turns. Sharp turns cause more back pressure and create resistance to air flow. Two 45-degree bends are more efficient than one 90-degree.

Always support hanging ducts at each joint with strapping. Secure duct work.

Exterior wall dampers should have a hood or flaps that keep out the weather. No hardware cloth or screen wire of any type should be in the exit air port. It will collect lint and block the air flow. Birds and critters will not inhabit your vent pipe if your vent system and damper are functioning properly.


Preparing for Installation

Installation of the Almetal ® Dryer Vent typically does not require any special experience. It can usually be installed in a few hours with standard construction tools. However, due to the wide variety of venting configurations found in homes, there may be some situations where it would be advisable to hire a contractor or carpenter to assist in installation of the Almetal™ Dryer Vent.

The Almetal ® Dryer Vent is available with either an end vent or a side vent. Refer to the following illustrations to determine which best suits your particular installation. These illustrations will help you determine the best way to install your Almetal™ Dryer Vent, what parts will be needed, and the complexity of your installation.


Installation Procedure

Measure carefully - position of the Almetal ® Dryer Vent receiver is very important. The receiver must be positioned directly behind the dryer exhaust pipe for the dryer to slide into place properly.

The diagram to the right shows the washer being used as the reference point.

a) Before beginning installation, turn on the dryer and check air flow at exterior damper for comparison after install.

b) Note the location of the dryer relative to a suitable reference point.  If the washer does not need to be moved to access back of dryer and the path to the outside vent, use it.  Otherwise, a wall, masking tape on the floor, or a small pencil mark will work
My reference point is: ____________________________________


c)  Prior to moving or disconnecting the dryer, measure from your reference point to the dryer.  If you wish to relocate the dryer from its old position, do so before making this measurement.  Be sure to leave at least 1/2" - 1" between the washer and dryer to allow for washer shift during the spin cycle.
Left/right distance from dryer to reference point: (A) _____________________

d) Remove the dryer from its location to access the work area.

e)  Unplug electrical cord or, in case of gas dryer, shut off gas.  Remove all existing hoses and vent parts.

f)  If installing a new dryer, adjust the dryer height to match the washing machine height.


g)  Assemble the exhaust pipe extender by bending it to form a cylinder and fitting together the crimped ends.   Install the exhaust pipe extender on the dryer exhaust pipe.  Measure from the floor to the bottom of the exhaust pipe extender.

This is the hardest part of the installation.  It may be relatively easy, taking only about a half hour in the simplest installations.  Or, it can be quite involved, requiring many hours to complete, as well as some additional  tools and carpentry skills. Before beginning, plan well and carefully determine the complexity of your installation.  You may need to purchase additional 4" piping and/or elbows. If the path from your dryer exhaust vent to the outside vent is a long or complex one, you may want to consider hiring a carpenter or contractor to complete installation for you.

a) If you have not already done so, refer to Preparing for Installation and determine how the periscope will be attached to the outside vent.  Obtain any additional piping, elbows, tape, etc. necessary.  If needed, periscope extensions in lengths of 4' can be ordered from Almetal™ Dryer Vent. 

b)  Adjust the periscope to the length you need for your installation.  In most cases, the periscope will need to be pulled apart, cut with tin snips, and reassembled to achieve the correct length.


c)  Insert the exhaust pipe extender into the receiver on the periscope.  Attach the periscope to the outside vent, using additional piping if necessary, and position the periscope on the wall so that the the receiver and exhaust pipe extender line up with where the dryer's exhaust vent will be. Use the measurements made in Part I to locate the  receiver and exhaust pipe extender precisely.  Don't worry about the length of the extender at this point. When receiver is in the correct position, mark the periscope's exact location on the wall. 

d)  Remove the exhaust pipe extender. Use metal foil tape to secure all duct pipe connections and any other spots where air could leak from the system. Do not tape the exhaust pipe extender to the periscope. 

e)  Check the periscope's location following application of metal tape.  Once it is positioned correctly, use the stainless steel screw and flat washer to fasten the periscope to the wall through the 4" receiver hole.  You will need to drill through the back of the aluminum wall of the periscope.



a)  In most cases the exhaust pipe extender will need to be cut to the correct length. You may find it is possible and desirable to locate the dryer closer to the back wall than it was previously.   However, do consider the location of the washer. Typically, you will want the washer and dryer fronts to line up.  The tail pipe should project at least 1" to 1 1/2" beyond the back of the dryer.  One (1") is all that goes into the receiver. The receiver is made to stop the extender at the correct depth. Measure and mark the exhaust pipe extender for cutting.

b)  Remove exhaust pipe extender and disconnect crimped edges so it is flat to allow cutting.  Cut to length using tin snips, then reconnect crimped edges.

c)  Put the exhaust pipe extender on the dryer's exhaust vent and use metal tape to secure.  We have included a 4" hose clamp to secure the extender to the dryer.  


a)  Install the dryer by sliding it back until the exhaust pipe extender fits into the receiver.  A small mirror will help in adjusting the dryer into the proper alignment. The normal distance for the exhaust pipe extender to slide into the receiver is 1".  You may want to mark this distance on the exhaust pipe extender so you can tell when it's in all the way.

b)  Reconnect electricity and gas, if applicable.

You should notice shorter drying times immediately.  Check airflow at damper.  You should notice better air flow than before installation of the Almetal™ Dryer Vent.


Cleaning, Very Important

Your dryer vent should be maintained and cleaned regularly. We recommend once a year. The Almetal ® Dryer Vent makes it easy. Just pull the dryer straight out from the receiver and away from the wall. You don’t need any tools. Insert an electric leaf blower into the receiver. Blow out for a minute or two and that’s it. Slide you dryer back into the receiver and you’re done. Remember it is very important to keep your vent clean and clear.
