The minimum end clearance for all models is 12 inches.
* Maximum mounting angle is 45°. Heaters mounted on an angle between 0° to 45° must maintain
clearances posted for 0° or 45°; whichever is greater.
The stated clearance to combustibles represents a surface temperature of 90°F (32°C) 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.
