IMPORTANT
: Single or multiple heater placement must be such that continu-
ous operation of heater(s) will not cause combustible material or materials in
storage to reach a temperature in excess of ambient temperature plus 90F°
(50C°).
It is the installer
’
s responsibility to ensure that building materials with a
low heat tolerance which may degrade at lower temperatures are protect-
ed to prevent degradation. Examples of low heat tolerance materials in-
clude vinyl siding, fabrics, some plastics, filmy materials, etc.
Refer to
“
Clearance to Combustibles
”
information on pages 6 to 8, and
Figure 1 and Table 1.

GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in general space
heating applications. Variance to these typical heights can occur in some applications:
•
Higher mounting heights due to structure or application requirements
•
Lower mounting heights: Area or
‘
spot
’
heat; locations with sufficient horizontal separa-
tion distance from personnel; areas with greater infiltration losses (near overhead doors,
etc)
