1.0 INSTALLATION INSTRUCTIONS
In planning the installation for the heater it is neces-
sary to determine where the unit is to be installed, the
type of flue system to be used (straight out, corner, or
elevated), and whether optional accessories (wall
switch or remote control) are desired. Gas supply pip-
ing should also be planned. Refer to the appliance data
plate on the base pan of the heater for all gas pres-
sures and input rate information.
The heater can be mounted on any of the following
surface:
1. A flat surface (minimum 6mm base).
2. Four (4) corner supports.
(Example: Four (4) concrete masonry blocks). These
supports must be positioned so they contact all four
(4) perimeter edges on the bottom of the unit.
Heater framing can be built before or after the heater is
set in place. Framing should be positioned to accom-
modate wall covering and heater facing material. The
heater framing should be constructed of 2" X 4" (51 x
102mm) lumber or heavier. The framing headers may
rest on the heater standoffs. Refer to Figure 2 and Fig-
ure 3 for heater and framing reference dimensions.
