3) Minimum non-combustible facing must be installed according to
the table on this page. Finishing material to be installed on top of
this.

R90 Wood FireplaceR90 Wood Fireplace
Combustibles may not extend to unit face.
Do not notch wallboard around standoffs.
The R90 may be placed on or near construction materials. The
combustion air kit, fi re stop spacer and roof fl ashings (not chase
fl ashings) may be placed directly on or against normal construction
materials. The chimney requires a minimum 2" (51mm) clearance. A
combustible mantle (to a depth of 10", 254mm) may be installed no
closer than 18" (457mm) above the warm air vent or 55-1/2" (1410mm)
from bottom of unit.
The chimney must be enclosed when installed in or passing through a
living area where combustible material or people may come in contact
with it. This is important to prevent possible personal injury or fi re
hazard.
For any further information, please call your dealer. Special restrictions
apply to the front and facing of the fi replace and nearby walls.
WARNING: If insulation is used, do not place the unit against it. Insulation
or vapor barriers, if used, must be secured to assure insulation and vapor
barriers remain in place and do not affect the required air spaces.
WARNING: Do not pack or fi ll required air spaces with insulation or other
material. No material of any kind is allowed in these areas.
NOTES:
1) Do not insulate the chase cavity with blown or fi ll type insulation
materials.
2) Local codes may not require a fi restop at the ceiling level for outside
chase installations; however, it is recommended for safety and the
reduction of heat loss.
3) We recommend that you insulate at least the fi rst fl oor of the chase
to prevent heat loss.
4) Some local codes require 1 hour fi re rating on one or all sides of
fi re chases. Check with your local authorities.
