Reducing Wall and Ceiling Clearances Safely
It is often desirable to reduce
the
minimum
installation
clearances by placing the
stove closer to walls so the
installation takes up less floor
space. You can safely reduce
the minimum clearances by
permanently installing a shield
between
the
stove
and
combustible
material.
The
rules for safe shields can be
complicated, so read them
carefully and follow them
exactly. Note that there may
be minor regional differences
in clearance reduction rules so
be sure to check with your
building or fire inspector
before proceeding.
7.4.1 Shield Construction Rules
See figure Clearances for shield construction to match each letter to a clearance.
- 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:
1090 mm (43 po.).
B Shield extension above appliance: 500 mm (20 in.).
C Minimum space behind shield: 25 mm (1 in.). In Canada 21 mm (7/8 in).
D Clearance along the bottom of shield: minimum: 25 mm (1 in.) and maximum: 75 mm
(3 in.).
E Minimum clearance along the top of shield at ceiling: 75 mm (3 in.).
F Mounting hardware must not be located closer than 200 mm (8 in.) from the vertical
centre line of the appliance.
G Edge clearance for ceiling shields to side and back walls: 75 mm (3 in.).
H Shield extension beyond each side of appliance: 450 mm (18 in.).
