PRE-INSTALLATION STEPS

The appliance is shipped with all gas controls
and components installed and pre-wired.
1. Remove the shipping carton. Remove the
shipping pad. Remove front face assembly
and hood exposing the front glass door.
2. Open the two spring latches securing the
glass door (under the firebox floor). Remove
the door by tilting it outward at the bottom
and lifting it up. Set the door aside, taking
care to protect it from inadvertent damage.
See Removing The Glass Enclosure Panel on
Page 32.
3. Remove the log set from the firebox. Handle
logs carefully to prevent breakage.
4. Remove the embers and volcanic stone from
the control compartment.
5. Remove top standoff (taped to side of outer
wrapper).
6. Remove the 4 screws on top, and install the
top standoff with the 4 screws (see Figure
12).

TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation is outlined
below. However, each installation is unique and
may result in variations to the steps described.
See the page numbers references in the follow-
ing steps for detailed procedures.
Step 1. FRAMING (Page 11): Install top
standoff spacer. Construct the appliance
framing. Position the appliance within the
framing. Secure with nailing flanges.
Step 2. (Page 13) Route gas supply line to
appliance location.
Step 3. (Page 14) Preparing the appliance
vent collar.
Step 4. (Page 14) Install the vent system and
exterior termination.
Step 5. (Page 26) Field Wiring
a. Millivolt Appliances - Install the operat-
ing control switch (not factory provided)
and bring in electrical service line for forced
air-circulating blower (optional equipment).
b. Electronic Appliances - Field wire and
install operating control switch.
Step 6. (Page 27) Install blower kit (optional
equipment).
Step 7. (Page 27) Make connection to gas
supply.
Step 8. (Page 28) Verifying appliance operation.
Step 9. (Page 28) Install the logs, decorative
volcanic stone and glowing embers.
Step 10. (Page 31) Install glass door front face
assembly and hood..
Step 11. (Page 31) Adjust burner to ensure

Warnings.

Step 1. FRAMING

Frame these appliances as illustrated in Figures
13 and 14 on Pages 12 and 13 (Figure 15
applies to corner framing installations only).
All framing details must allow for a minimum
clearance to combustible framing members as
shown in Table 5 on Page 10.
If the appliance is to be elevated above floor level,
a solid continuous platform must be constructed
below the appliance.
Headers may be in direct contact with the
appliance top standoff spacer (Figure 12),
maintaining the 4" clearance to the fireplace top,
but must not be supported by them or notched
to fit around them. All construction above the
appliance must be self-supporting. DO NOT use
the appliance for structural support.
The fireplace should be secured to the side
framing members using the unit's side nailing
flanges - one top and bottom on each side of
the fireplace front. See Figure 13. Use 8d nails
or their equivalent.
SIDE NAILING FLANGES
Bend out the appropriate nailing flanges for
the drywall/finish material to be used. Nailing
flanges are provided for flush framing, 1/2" and
5/8" framing depths (see Figure 13).
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

IMPORTANT!
Install top standoff
and bend up appropriate
drywall backstops (1/2" or 5/8")
before installing fireplace.

Side
Framing
NOTE: The nailing flanges, combustible members,
and screw heads in areas directly adjacent to
the nailing flanges are EXEMPT from the 1/2"
clearance to combustible requirements for the
firebox outer wrapper.
Combustible framing may be in direct contact with
the nailing flanges and may be located closer than
1/2" from screw heads and the firebox wrapper in
areas adjacent to the nailing flanges.
Frame the opening to the exact dimensions
specified in the framing details in this manual.
