Clearances For Combustible Finishing With Mantel; Combustible Mantel Leg Clearances - Regency Fireplace Products Greenfire GF900C-NG2 Owners & Installation Manual

CLEARANCES FOR COMBUSTIBLE FINISHING WITH MANTEL

Due to the extreme heat this fireplace emits, the mantel clearances are critical.
Combustible finishing and mantel clearances are shown in the diagram
on the right. Finishing Trim must be used with combustible finishing.
Note: Maximum combustible finishing material thickness is 19mm
measured from the front of the fireplace opening. If total
finishing material is greater than 19mm, non-combustible
must be used.
Note: Ensure the paint that is used on the mantel and the facing is
"high quality" or the paint may discolour.
Note: Combustible mantel starts at 796mm (618mm + 178mm) from
unit base.
