5. Reducing Wall and Ceiling Clearances Safely
It is often desired to use as little space as possible when installing
a wood stove. To do this, it is possible to reduce the clearances
safely and install the stove closer to the walls by permanently
installing a heat shield between the stove and the flammable
material.
The rules for heat shields are sometimes complicated. Read
and apply the instructions carefully. Some regions may have
different regulations. Consult the local building code or contact
the fire department for restrictions, inspection and installation
requirements in the area.
5.1 Shield Construction Rules
− Adhesives used in shield construction must not ignite or lose adhesive qualities at temperatures
likely to be encountered.
− Mounting hardware which extends from the shield surface into combustibles may be used only
at the edges of the shield.
− Mounting hardware must allow full vertical ventilation.
A) Minimum clearance between the appliance
top and an unshielded combustible ceiling:
49 ¾" (1264 mm)
B) Shield extension above the appliance: 20"
(1264 mm)
C) Minimum space behind the shield: 1" (25 mm).
In Canada 7/8" (21 mm)
D) Clearance along the bottom of the shield:
minimum 1" (25 mm) and maximum 3" (75 mm)
E) Minimum clearance along the top of the
shield: 3" (75 mm)
F) Mounting hardware must not be located
closer than 8" (200 mm) from the vertical
centre line of the appliance.
G) Edge clearance for ceiling shields to side and
back walls: 3" (75 mm)
H) Shield extension beyond each side of the
appliance: 18" (450 mm)
