7 Clearances to Combustible Material
The clearances shown in this section have been determined by test according to
procedures set out in safety standards ULC S627 (Canada) and UL1482 (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.
7.1 Location of the certification label
Since the information given on the certification label affixed to the appliance always
overrides the information published, in any other media (owner’s manual, catalogues,
flyers, magazines and/or web sites) it is important to refer to it in order to have a safe and
compliant installation. In addition, you will find information about your stove (model, serial
number, etc.). You can find the certification label on the back of the stove.
7.2 Clearances to Walls and Ceiling
The clearances to combustible walls may be slightly different in Canada and the U.S.A.
and may also differ depending on whether you use single or double wall flue pipe. Please
be sure to choose the correct clearance for your location and type of flue pipe. See figure
Clearances to combustible materials and floor protection to match each letter to a
clearance.
