Reducing Wall And Ceiling Clearances Safely; Shield Construction Rules - Osburn 2200 Installation And Operation Manual

2200 Installation and Operation Manual
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
permanently installing a shield
between the
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.

1353 mm (53.25 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
