How To Connect A Wood Furnace To Existing Ductwork

Installing furnace ducts from an outdoor wood furnace into your home is easier than you might think. Outdoor wood or gas furnaces are less dangerous, cleaner, and just as efficient as indoor furnaces. Using these guidelines, install outdoor furnace ducts from your natural outdoor heat source into your home.

How To Connect A Wood Furnace To Existing Ductwork – A Step-By-Step Guide

Step 1: Remove The Old Furnace From The Ductwork

Firstly, Disconnect the old furnace’s power supply and reroute the existing ductwork to where it will be connected to the new outdoor furnace. To avoid cutting a hole in the foundation or a sidewall of the house, direct the ductwork toward a small basement window. Measure the window to later sell it with coated plywood and stripping.

Step 2: Locate The Best Location For The New Outdoor Furnace

Secondly, Select a location for the furnace that is at least 10 feet away from your house. To avoid chimney drafts and to extinguish the wood or gas fire, the location must not be in the path of prevailing winds.

Step 3: Measure And Buy Enough Galvanized Ducting

Thirdly, determine the exact size of ducting required by your new outdoor furnace. After that, purchase enough galvanized ducting to connect the furnace to your home.

Step 4: Dig A Ductwork Trench

Dig A trench for the ductwork with the tractor and a backhoe. It should be 1 inch deeper and wider on all sides than the ducting to accommodate insulation materials and an adequate amount of soil and gravel fill. You should also focus on the cleaning of your vent. For this purpose, immediately contact dryer vent cleaning Marietta

Step 5: Install And Insulate The Ducting

After that, Fasten the ducting lengths together with band fasteners and screws. Apply a uniform layer of duct tape to all band fasteners. Wrap the ducting in a single layer of 1/4-inch Solarguard (TM) Mylar insulation.

Step 6: Construct The Ductwork Trench

Fill the trench bottom with fine gravel along its entire outdoor length. With a heavy, wide-spaced gravel rake, level it and smooth it.

Step 7: Install The Ductwork In The Trench

Lastly and most importantly, Lay the ductwork carefully into the trench with your helper. Moreover,  please ensure that all the sections are securely fastened.

Step 8: Engage The Outdoor And Interior Ductwork  

Connect the length of outdoor ductwork to the interior ducts you already have. After that, seal off the window where the ductwork enters. Insert the PVC-coated plywood into the window opening. After that, secure the plywood stripping around all four sides to create a weatherproof seal.

Step 9: Remove Soil From The Ductwork Trench

Replace the soil from the trench, pack it firmly around the ductwork, and level with the ground surface.

Step 10: Put The Ductwork To The Test

Turn on the outdoor furnace switch, open the register vents, turn on the fan, and check for warm air. Check the connections to the new furnace and the existing ductwork if warm air is not reaching the registers.

However, if you face any difficulty,  it is always wise to contact  professionals. Contact air duct repair and replacement Marietta now.

Ductwork For A Wood Stove

Connecting your wood stove fan directly to your central heating ducts is dangerous. Instead, you’ll need to install a ceiling vent in a distant room to get started with the duct fan method. Connect your duct and run it through your ceiling to the stove. Install a wood stove duct fan at the end, keeping it oriented to suck up air through the duct.

As cold air passes across your wood stove, it will emit warm air. During the winter, this warm air can heat your home and provide an excellent source of warmth.

Other ways to take advantage of the heat provided by your wood stove are shared by Upgraded Home. However, Installing a fan on top of the stove is an option as long as it is not in a fireplace and is freestanding. A fan installed on top can push the heat up and out of your home, making it cozy and warm. Additionally, to help with circulation, you can also purchase a few oscillating fans.

Working Of A Wood Stove

According to Best Pick Reports, wood stoves are more commonly used in colder parts of the country and can be traced back to the 1500s. They have a stove, chimney, baffle, and damper and are made of cast iron, steel, or stone. Therefore, When you start burning the wood inside, the heat it produces warms the stove and the air in the room. As a result, the smoke is drawn up and out through the stove’s chimney.

The baffle on the woodstove (there may be more than one) accelerates the combustion time of the fire gasses. Therefore, it is critical because partially combusted gasses pollute the air. Finally, the damper allows you to control the airflow into the stove, which affects the size of the fire and the amount of heat it produces. 

Moreover, Modern wood-burning stoves are environmentally friendly and efficient, and they should meet EPA requirements. However, if you have one inside your home, you should also have smoke and carbon monoxide detectors. In addition to this, Remember to test and replace the batteries at least twice a year.


In conclusion, we can say that connecting a wood furnace to existing ductwork is an easy process.  Moreover,  one can do it at home with a helper. However, you should also clean your ductwork regularly.
