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 8, Figure 3.
For typical shelf mounting on existing shelf, See 
Page 9, Figure 4.

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 a location that is 
readily accessible for servicing.

The heater must be installed in accordance with 
clearances to combustibles as indicated on the wall 
tag and in this manual.

5.3 Wall Mounting
For typical suspension, See Page 9, Figure 5. Wall 
mounted heaters blowing parallel to the wall can 
only be installed with the service door away from the 
wall.

The wall mounting brackets must be attached to a 
suitable wall using all mounting holes. Screw sizes 
less than 3/8" may not be used. In order for the wall 
mounting brackets to adequately carry the weight of 
the heater, it must be installed according to best 
building practices.
