Heaters are designed for installation above 6'
(1.8 m). These heaters must be installed within the
heated space. Duct delivery systems are not
permitted with axial fan units. When handling or
supporting the heater from below, ensure that the
weight is taken at the support points.
The gas or electrical supply lines must not be used
to support the heater.
Do not locate the gas or electrical supply lines
directly over the path of the flue products from the
heater.
The heater must be installed in accordance with
clearances to combustibles as indicated on the wall
tag and this manual.

Four suspension points (3/8" nuts) are located on
the top of the heater. Drop rods must be 3/8"
diameter mild steel.
When handling or supporting the heater from below,
ensure that the weight is taken at the support points.
For typical suspension, See Page 11, Figure 5.
