Minimum Non Combustible Material Clearances
If Not Using Mantel
Note: If using a mantel, go to column 3. If not using a mantel, follow the information on this page.
You must have non combustible material(s) above the fireplace opening. Non combus- tible 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 mate- rial must extend at least 8" up (for all mod- els). If non combustible material is less than 12", you must install the fireplace hood accessory (24", 30", and 36” models only). See chart below and Figure 4 on page 6 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 Operation, page 9.
