Chart 1.1 •
Clearance to Combustibles in Inches (see Figure 1.1 for Mounting Angles)
The stated clearance to combustibles represents a surface temperature of 90ºF (32ºC) above room
temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas,
tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent materials are protected from degradation.

Mounting Angles
* Heaters mounted on an angle between 1° to 29° must maintain clearances posted for 0° or 30°; whichever is greater.
