Pellet Inserts

Our Pellet Burning Fireplace Inserts are a great way to update an old inefficient fireplace while still getting the heat value of wood burning without having to do all the work of cutting, splitting and lugging wood inside your home. Simply fill the hopper with a bag of pellets, set the thermostat to the desired temperature and the pellet insert will burn and hold the temperature until the hopper is empty. Slide the pellet insert into a masonry fireplace and install a stainless steel chimney liner kit and you are ready to press the ignition button.

Typical Use & Summary:

Slide the insert inside a masonry fireplace and connect to our stainless steel flexible chimney liner kits for peak performance and easy maintenance.

Simply fill the hopper with pellets, set the heat setting to the desired temperature and the pellet insert will hold the selected temperature until the hopper is empty with pellets.
