INSTALLATION
Note:  43" (1092mm) is the minimum height for fl ex termination and 
Simpson Dura-Vent  terminations.
Diagram 1
1)  Determine the total thickness of facing material (eg. drywall plus 
ceramic tiles) to allow the fi nished surface to be fl ush with the front 
of the unit. Total facing thickness can vary from 1/2" (13mm) to
 1-1/4" 
(32mm) 
thick.
2)  Frame in the enclosure for the unit with framing material. The framed 
opening for the assembled kit is 47-1/2" high x 48-1/2" wide x 26-1/4" 
deep (1207mm  H x 1232mm W x 667mm D). See Diagram 1. See 
important note below when installing with any veritical venting off of 
the top.
3)  For exterior walls, insulate the enclosure to the same degree as 
the rest of the house, apply vapour barrier and drywall, as per local 
installation codes. (Do not insulate the fi replace itself.)
4)  The unit does not have to be completely enclosed in a chase. The 
clearance on top of the unit from the top standoffs is 0" so combustible 
building materials can be laid directly on top of the standoffs. You 
must maintain clearances from the vent to combustible materials: See 
"Clearances" section.  Combustible materials can be laid against the 
side and back standoffs and the stove base.
FRAMING & FINISHING
IMPORTANT
When installing the unit with any vertical venting off the top of the 
unit as shown, the minimum framing depth changes accordingly.
The  HeatWave Duct Kit has different 
clearance and framing requirements, 
check the HeatWave manual for details.
