The HeatShield® PriorFire Retrofit Fireplace System (patent pending) is a lab tested, field proven, engineered fireplace. Because of its unique shape, materials, and “Air Wing” over-fire air injection system, it produces more heat, fewer emissions, and a tall “fun to watch” flame when compared to a traditional masonry fireplace.
Solves Fireplace Clearance Problems
The PriorFire Retrofit Fireplace System is UL listed zero clearance to combustibles with 4” nominal masonry.
One Size Fits Most
This unit can be installed in any residential fireplace with a width of 30”-41”, an opening height of 26”-30”, and a minimum depth of 22”. Note: depth and interior width is easily achieved by removing the firebox rear and side walls before installing product.
Produces 2-3 Times More Heat Than the Average Masonry Fireplace
The unit is built with light weight fire brick, so the firebox lining accumulates less heat than standard firebrick or heavy castable materials. More heat radiates into living spaces instead of absorbing into the surrounding masonry.
The unique back wall “Air Wing” shape keeps the flame in contact with the rear wall of the fireplace. Preheated overfire air is syphoned or injected into the flame through the air injection slots in the back wall.
This secondary combustion feature burns off additional particulates before they reach the flue. More complete combustion means a more efficient fireplace with less pollution and less creosote buildup than a standard fireplace or similar products.
