Install and use in Masonry Fireplaces
STEP 1
A 4 1/4″ hole is drilled through the fireplace wall no more than 4″ from the floor of the fireplace to the bottom of the hole.
STEP 2
The fireplace vent is installed horizontally through the fireplace wall with the flange and cap on the inside. A louver screen is installed on the exterior wall to prevent the intrusion of bugs and small animals.
STEP 3
The Drescher Air Vent will efficiently draw cold air from outside the home and generate the proper environment for combustion, using unheated, free air.
