POSITIONING THE UNIT: The more extended the insert, the greater the heat
transfer to the room. When installed as an extended insert, the front edge of the air
jacket will be installed flush with the fireplace facing. Otherwise the unit can be
moved back as much as 2.5" (64 mm) or any position in between. The position
chosen will depend on your own preference for most installations (where the lintel is
less than 6" (152mm) and the depth is greater than 12.5" (318mm)). See the table
and Figure 5.
