Chart 2.1 • Clearance to Combustibles in Inches (see Figure 2.1 for Mounting Angles)
* Heaters mounted on an angle between 0° to 45° must maintain clearances posted for 0° or 45°; whichever is
greater.
NOTE: Use high BTU output when determining clearances. The minimum end clearance is 12 in.

personal injury, property damage and/or death.

LD3 Series 2.0 Safety • Clearance to Combustibles
of the proposed installation.
In locations used for the storage of combustible materials, signs must be posted to specify the maximum
permissible stacking height to maintain the required clearances from the heater to the combustibles.
Signs must either be posted adjacent to the heater’s thermostat or in a conspicuous location.
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.
