Clearance to Insulation & Vapor Barriers
FIGURE 33
The STANDARD Series firebox back wall, the firebox side walls and the smoke dome back require 1-1/2” clearance.
(Figure 32) Keep all insulation and vapor barriers a minimum of 3” away from all Isokern fireplace surfaces.
Keep all insulation, vapor barriers, “house wrap” paper and other insulating type membranes and products, including
fiberglass, cellulose and other insulation, a minimum of three inches (3”) away from all STANDARD surfaces. (Figure 33)
When STANDARD fireplace installations are surrounded by walls that are to be insulated, the walls must have enough clearance to
the Isokern unit in order to maintain the three inch (3”) minimum clearance to insulation. (Figure 33) Never spray the STANDARD
fireplace with any type of sealer, insulation or other material.
If insulation or vapor barriers are used in walls surrounding the STANDARD fireplace, it is strongly recommended that the walls be
sheathed with gypsum board, plywood, particle board or other material on the side facing the Isokern to assure the insulation and
vapor barriers remain in place and a minimum of 3” away from the unit.
