Panel Kit Option Details

Steel Top Panel Kit

The top steel panel is the same black color as the stove and will be a perfect match. Matched with the black side panels provides a simple yet elegant look for your stove. Or, add the soapstone side panel kit to increase radiant heat.

Soapstone Top Panel Kit

The soapstone top panel kit is a beautiful stone that provides added heat output even after the stove has cooled. Soapstone has very slow thermal release and will retain heat. The soapstone top panel kit will enhance the performance of the stove. The stone will allow the firebox to retain the heat for a longer period of time, extending the life of the coals and making the stove easier to re-light.

Black Side Panel Kit

The black side panel kit will match the finish of the wood stove. Pair the black side panel kit with the steel panel top to have an all black and sleek looking stove. The panels easily attach to the stove and gives the stove more dimension than other wood stoves. The panel kit comes with 6 panels and the trim to finish off the stove.

Soapstone Side Panel Kit

If you are looking for the most possible heat output from the Matrix stove, the soapstone side panel kit is for you. Soapstone features amazing thermal release properties that allow the stove to stay hotter longer. Paired with the soapstone top panel, this will increase the heat output of the stove substantially. Soapstone's beautiful grain will truly enhance the appearance of the stove and will likely be the focal point of any room it's installed in.

Optional Accessory Details

Rigid Firescreen

The rigid firescreen allows you to burn wood in the stove with the door open, just like an old-time fireplace. Hear the crackle of the wood, watch the flames dance around in the firebox, and relax around the wood stove on a cold winter's night. The rigid firescreen is easy to install and easy to remove when you are ready to load more wood. The stove should not be burning with the door open without the firescreen.

Fresh Air Intake Flexible Insulated Pipe

The insulated flexible fresh air intake pipe is the perfect choice for adding fresh air to the stove. Measuring 4' in length and 5" diameter, this can be used for going straight out of the wall behind the stove. A fresh air intake register and the fresh air intake clamps are necessary to finish the installation. The insulation will help prevent the air intake from being cold in the room. A fresh air intake must be installed when installing the Matrix in a mobile home.

5" Air Intake Termination with Clamps

The 5" air intake termination with clamps easily attaches to the insulated fresh air intake pipe and provides you with the remaining parts necessary to properly terminate the intake. The intake termination comes with the register hood as well as the clamps which make for an air tight seal to the stove, preventing an unwanted draft when the stove is not running.

5" Fresh Air Intake Register with Airtight Damper

The 5" Fresh Air Intake Register with Airtight Damper opens and closes the fresh air supply to a wood stove. It's simple mechanism makes it possible to close the damper tightly when the wood stove is not in use. This will ensure the wood stove is not being cooled while the stove is not in use.
