C. MOUNTING HEATER WITH OPTIONAL HEARTH BASE TO OPTIONAL
MANTEL (The following instructions are for GMF800(A,B)/GMU801(A,B)
series models only. For other mantels, see instructions included with
mantel kit.)
Assembling Mantel
Only use the optional mantels specified in this manual. See Accesso-
IMPORTANT:
ries, page 34 for proper mantel kits. Before installing mantel to heater, the heater
must be mounted on the optional hearth base.
Installing Mantel to Heater
If using a GA series heater blower accessory on a heater equipped with a
GHB802 or GHB802A hearth base, the mantel clearance to back wall
should be 3/4 inch. This will improve flame appearance and combustion.
This mantel clearance is not needed if using a GHB802B or GHB38 hearth
base.
Before installing mantel to heater, the heater must be mounted on the optional
hearth base. See Mounting Heater on Optional Hearth Base, page 17. Follow the
steps below to install mantel to heater.
1. Place mantel over heater (see Figure 22). Back side of mantel should be even
with back of hearth base. Mantel front should not extend past brass trim around
heater cabinet.
