COLD CLIMATE INSULATION

For cold climate installations, seal all cracks around your fireplace with noncombustible material and wherever cold
air could enter the room. It is especially important to insulate outside chase cavity between studs and under floor on
which fireplace rests, if floor is above ground level. Gas line holes and other openings should be caulked or stuffed
with unfaced fiberglass insulation. Caulk the firestop only where the pipe penetrates an outside wall, attic, or other
unconditioned space.
NOTE: Do not use loose, or blown-in insulation in the cavity surrounding the fireplace.
If the fireplace is being installed on a cement slab in cold climates, a sheet of plywood or other raised platform can
be placed underneath to prevent conduction of cold transferring to the fireplace and into the room. It also helps to
sheetrock inside surfaces and tape for maximum air tightness and caulk firestops.
