Minimum Non Combustible Material Clearances
If Using Mantel
You must have non combustible material(s) above the fireplace opening. Non combustible
materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal,
you must have non combustible material behind it. Non combustible material must extend
at least 8 inches up (for all models). If non combustible material is less than 12", you must
install the fireplace hood accessory (24" and 30" models only). Even if non combustible
material is more than 12", you may need the hood accessory to deflect heat away from your
mantel shelf. See chart below and Figures 7 and 8 (page 8) for minimum clearances.
IMPORTANT:
If you cannot meet these minimum clearances, you must operate heater with
chimney flue damper open. Go to Installing Damper Clamp Accessory for Vented Opera-
tion, page 8.
