NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
The fireplace should be secured to the side framing
members using the unit's nailing flanges - one top
and bottom on each side of the fireplace front. See
Figure 6. Use 8d nails or their equivalent.

Flanges to the Framing
Figure 6
Note: The nailing flanges, combustible members
and screw heads located 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 of this manual.

Step 4. (page 21) Field Wiring
a. Millivolt Appliances – The operating control
switch is factory installed.
b. Electronic Appliances – Connect 120 Vac
electrical power to the appliance receptacle.
Step 5. (page 22) Install blower kit (optional
equipment).
Step 6. (page 22) Make connection to gas
supply.
Step 7. (page 23) Install the logs, vermicu-
lite and glowing embers.
Step 8. (page 23) Checkout appliance operation.
Step 9. (page 23) Install glass door frame
assembly.
Step 10. (page 24) Adjust burner to ensure
proper flame appearance.
See
Figure 10 on page 8 for corner framing
installations. All framing details must allow for a
minimum clearance to combustible framing mem-
bers as shown in
Table 2 on page 4.
If the appliance is to be elevated above floor level,
a solid continuous platform must be constructed.
Headers may be in direct contact with the appli-
ance top spacers but must not be supported by
them or notched to fit around them. All construc-
tion above the appliance must be self supporting,
DO NOT use the appliance for structural support.
Step 2. ROUTING GAS LINE
Route a 1/2" (13 mm) gas line along the inside
of the left side framing as shown in
Figure 7.
Gas lines must be routed, constructed and
made of materials that are in strict accordance
with local codes and regulations.
All appliances are factory-equipped with a flex-
ible gas line connector and 1/2 inch shutoff
valve. (See step 6 on page 22).
Step 1. FRAMING
Frame these appliances as illustrated in
Figure
9 on page 8, unless the appliance is to be
installed in a corner
.

All horizontal terminations
may be located as close
as 6” (152mm) to any
(non-combustible and
combustible) exterior
sidewall. This distance
may be decreased to
2” (51mm) for non-
combustible exterior
sidewalls only, if the
SV4.5HT-2 termination
is used.
DETAILED INSTALLATION STEPS
The appliance is shipped with all gas controls
and components installed and pre-wired. Re-
move the shipping carton, exposing the front
glass door. Remove the cardboard from un-
derneath the pressure relief plates. Remove
the bottom panel by lifting and pulling it to-
wards the front. Open the two latches (located
under the firebox floor) securing the glass
door. Remove the door by tilting it outward at
the bottom and lifting it up. Set the door aside
protecting it from inadvertent damage.
See
Figure 39 on page 23.
