ALTERNATIVES FOR WALL PROTECTION


Example: The rear clearance for the Model 80 from page 12 is 26". (Measurement A.) This clearance may be
reduced by 66% by using either of the wall protection devices mentioned below.

Tested and Listed Wall Protector


Clearances to combustibles may be reduced if a tested and listed wall protector is installed over a combustible
surface when the following condition exist:
1. A dead air space or 1" separates the listed and tested wall protector from the combustible surface.
2. The tested and listed wall protector extends from floor to ceiling with a 1" clearance for air circulation at both

the floor and ceiling.

3. The 1" spacers (preferable ceramic rather than metal) must be located at the corners rather than behind the

heater or the chimney connector.

Unlisted and Untested Wall Protector


Wall protectors may be constructed of masonry, 24 gauge or thicker sheet metal, or non-combustible 1/2" thick
insulation board. Conditions 2 and 3 above must be observed but the air space in condition 1 must be increased to 1
1/2".

FINAL CHECK

1. Recheck the specified clearances.
2. Remove all foreign material from the firebox area.
