3. Clearances to Combustible Material
The clearances shown in this section have been determined by tests according to procedures
set out in safety standards ULC S627 (Canada), UL 1482 (U.S.A.) and UL 737 (U.S.A.). When
the stove is installed so that its surfaces are at or beyond the minimum clearances specified,
combustible surfaces will not overheat under normal and even abnormal operating conditions.
No part of the stove or flue pipe may be located closer to combustibles than the minimum
clearance figures given.
Clearances may only be reduced by means approved by the regulatory authority.
The clearances to combustible walls may be slightly different in Canada and the U.S.A. and may
also differ depending on whether single or double wall flue pipe is used. Make sure to choose
the correct clearance for the stove location and type of flue pipe.
The clearances of the appliance and the flue pipes must be met individually, meaning the appliance
cannot be installed closer to the combustible materials than the single or double wall pipe allows.
For a safe way to reduce clearances refer to section"5. Reducing Wall and Ceiling Clearances Safely"
of this manual.
