ASSEMBLY INSTRUCTIONS
Combustion Air Intake
This appliance requires a source of combustion air. If you home is of tight construction, has negative
pressure problems or is a mobile / manufactured home, you will need an outside source of air.
You have two options. You may cut a rectangular hole in the floor of your home and the floor protector, or
purchase a standard 4” Dryer Vent kit from your local hardware supply store and install it on the rear of the
pedestal.
If your choice is to cut a rectangular hole in the floor and flooring protector, refer to the below illustrations for
assistance. You must place a rodent screen between the floor protector and the floor to prevent passage of
any unwanted vermin into your home.
If using a Dryer venting kit, the outlet cover must be of a design that DOES NOT close by means of
a flap or trap door.
You must purchase a style that allows a continuous in-flow of air and that has a rodent
screen. You will also need a Combustion Air Adapter to attach to the pedestal of the appliance. This adapter
can be purchased from your dealer.
If your home is not of tight construction or not a manufactured mobile home, you can just simply remove the
4” round knockout in the rear of the pedestal.
“Combustion Air thru Unit Base” installation:
First, decide the location of the appliance. Then, cut a 2” x 6” rectangular opening in the floor protector
within the appliance base’s perimeter. Using the flooring protector as a template, position it in place
and mark onto the floor of your home where to make your next cut. Make the cut in your home’s floor
slightly larger than the 2” x 6” to accommodate any misalignment. Attach a piece of screen over the
hole to prevent any unwanted vermin entering your home. Complete your appliance install.
“Dryer Venting Kit” installation:
Begin by installing the 4” adapter to the rear of the appliance using the screws provided. If not already,
remove the round knock-out from the pedestal. Follow the manufacturer’s installation instructions for
attaching the dryer vent kit to the home. Then attach it to the adapter on the appliance.
