HE+ Series Infrared Gas Heater Installation and Operation Manual
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 90 F°
(50 C°).
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.
* TYPICAL MOUNTING HEIGHT provides optimum comfort in general space heating applica-
tions. Variance from the typical height can occur in applications:
• Higher mounting heights due to structure or application requirements
• Lower mounting heights for area or ‘spot’ heat, or in areas with greater air movement /
infiltration losses (near overhead doors, etc)
• Lower mounting height when the diagonal distance from a heater to personnel provides a
distance value similar to the Typical Mounting Height
