of heater (see Figure 17).
2. Mark screw locations on wall.
3. Remove heater from mounting bracket.
4. If installing bottom mounting screws into hollow or solid wall, install wall anchors.
Follow steps 1 through 4 under Attaching To Wall Anchor Method, page 15.

tions using 9/64" drill bit.

B. MOUNTING HEATER ON OPTIONAL HEARTH BASE
Figure 17 - Installing Bottom Mounting Screws
WARNING
If installing the GHB802 or GHB802A base on heater, and using with a GA
series heater blower accessory along with a GS601 surround or a GM800
or GM900 series mantel, the surround or mantel clearance to back wall
should be 3/4 inch. This space is not necessary if using a GHB38 or
GHB802B hearth base. This will improve flame appearance and combus-
tion. Use only a GHB802B or GHB38 hearth base if using a GA series
heater blower accessory with a GM700 series, GMC32F or GMC33U
corner mantel.
Tools needed: #2 Phillips screwdriver, slotted screwdriver, and electric drill (if
securing base to floor)
The optional hearth base kit includes the following:
Hearth Base
4 Wood Screws
4 Sheet Metal Screws
Brass Base Trim
Hearth Insert
4 Anchors
Laminate Sheet & adhesive
2 Brass Screws
Note:
It is an option to secure “A” model hearth base to floor. You must secure the
“B” or GHB38 model hearth base to floor. To secure hearth base to floor, follow
instructions under Securing Hearth Base to Floor, below. If not securing hearth
base to floor, proceed to Mounting Heater to Optional Hearth Base, page 17.
Securing Hearth Base to Floor
1. Position hearth base in desired location. Mark holes for drilling (See Figure 18,
page 17). 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.
