Minimum Non Combustible Material Clearances
If Not Using Mantel
Note: If using a mantel, go to page 11. If not using a mantel, follow the informa- tion on this page.
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" up (for all models). If non combus- tible material is less than 12", you must install the fireplace hood accessory (24" and 30" models only). See chart below and Figure 5 for minimum clearances.
IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open.
