B. MOUNTING HEATER ON
OPTIONAL HEARTH BASE
WARNING: If installing the
GHB802 or GHB802A base on
heater, and using with a GA se-
ries heater blower accessory
along with a GS601 surround or
a GM800 or GM900 series man-
tel, the surround or mantel clear-
ance to back wall should be 3/4
inch. This will improve flame
appearance and combustion.
Use only a GHB802B, GHB802C,
OR GHB38 series hearth base if
using a GA series heater blower
accessory with a GM700 series,
GMC32F series, or GMC33U se-
ries mantel.

following:
• Hearth Base

Securing Hearth Base to Floor
1. Position hearth base in desired location.
Mark holes for drilling (See Figure 18,
below). Remove hearth base.
2. For carpeted floor, make a small cut with
a sharp knife at marked locations before
drilling. If securing to a wood floor, drill a
3/4" deep hole using a 1/8" diameter drill
bit. Do not use anchors in wood floors.
If securing to a concrete floor, drill a 1
deep hole using a 1/4" diameter concrete drill
bit. Completely insert anchors into each hole.
3. Mount heater to hearth base following
steps under Mounting Heater to Op-
tional Hearth Base. After mounting
heater, position heater and hearth base
over drilled holes. With slotted screw-
driver, secure hearth base to floor with
four wood screws.
Mounting Heater to Optional

the bottom of heater overhanging the
edge of the table.
2. Remove 2 shipping screws in bottom
of heater. Discard shipping screws.

base with holes in bottom of heater (see

4. Using a Phillips screwdriver, secure
hearth base to heater with four sheet
metal screws (see Figure 18).
5. Stand heater up on base.
