HEI150 Wood Insert Fireplace Installation and Operation Manual

8 Clearances to Combustible Material
The clearances shown in this section have been determined by test according to procedures
set out in safety standards ULC S628 (Canada) and UL1482 (U.S.A.). When the insert 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 insert may be located closer to combustibles than the minimum
clearances given below.
8.1 Location of the Certification Label
Since the information given on the certification label attached 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 insert (model, serial number,
etc.). You can find the certification label on the side of the insert.
To access the certification label, the faceplate may need to be removed. Therefore, we
recommend that you note the insert’s serial number on this manual, since it will be needed
to precisely identify the version of the appliance in the event you require replacement parts
or technical assistance.
8.2 The Masonry Fireplace Throat Damper
If the fireplace's draft control system is to remain in the masonry fireplace, it must be locked
open for access of the chimney liner or removed entirely. If you remove draft control system
from the masonry hearth, you will need to install the metal plate (27009), supplied with the
owner’s manual kit, indicating that the masonry hearth has been modified. It must be secured
inside the masonry hearth, in a visible place and easy to locate.
8.3 Compliance of a Combustible Mantel Shelf
The maximum shelf depth allowed is 12'' (305 mm). Whatever the shelf depth of less than
12'' (305 mm), the minimum distance from the top of the unit is 13 1/2'' (343 mm).
