7.4 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
:
1346 mm (53 in.).
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.).
