RECOMMENDED 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 for area or ‘spot’ heat, or in areas with greater infiltration losses
(near overhead doors, etc)
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 pro-
tected to prevent degradation. Examples of low heat tolerance materials
include 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.

INCORPORATING
90° ELBOWS AND 180° ELBOWS
The radiant tube heater can be installed in configurations as illustrated in FIGURE 4 (next
page)
with a maximum of two 90° elbows per heater. The use of elbows reduces the total
maximum vent allowable. (See Section 11 : Flue venting)
