Fresh Air Intake with Damper Install Guide

Forced Air Distribution Kit

Are you looking to gain a bit more heating capacity out of your Osburn Horizon zero clearance fireplace? The Forced Air Distribution Kit offers a powerful 300 CFM blower that forces hot air from the fireplace to other rooms in the home. Connect the distribution kit to the insulated flex duct and heat more of your home. The Forced Air Kit can heat adjacent rooms either on the same level, above the fireplace and even below the fireplace up to 50' away. The blower must be a minimum of 10' from the fireplace and there must be a minimum of 25' of insulated pipe between the blower and the air outlet register. The distribution kit operates with a thermal disc which will turn on the blower once the firebox has reached a certain temperature and will turn off when the firebox has cooled down. Forced Air Distribution Kit Install Guide

6" x 25' Insulated Flex Pipe for Forced Air Dist. Kit

If you choose to install the Forced Air Distribution Kit to the fireplace, the 6" x 25' insulated flex pipe is a great choice to route your forced air into your existing heating ducts. The insulation will help keep the air warm for better heating capabilities.

Warm Air Circulating Grille

Looking to get more heat from the Osburn Horizon zero clearance fireplace? Install the Warm Air Circulating Grille and you'll get just that. There are no moving parts. The grill will use the radiant heat from inside the chase to push warm air into the room. Install the intake grille on one side of the chase close to the floor and install the top grille over the top of the fireplace. Natural convection will create a draw and push warm air into the room. For optimal air circulation, position the grille on one of the fireplace enclosure sides. The grille can also be installed on the enclosure’s front wall, but the air circulation will be reduced.
