Superior Standard Series Unvented Decorative Gas Fireplaces VFPF-CMN-2 - Manual (Page 8)

NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE. 8
All appliances have a 3" long ³⁄₈" NPT nipple
installed at the valve. To quickly and easily
complete the gas line routing, use the gas flex
line kit, Model GFLV.

Step 3. Remove the nailing flanges from the
lower control compartment and install in place
with three (3) screws each. Align with the three
holes on each side of the appliance (refer to
Figure 5 ).
Install the hood on all units. Position the hood in
the open area above the appliance door. Insert the
tabs, on each end of the hood, into the bracket at
each end. Bend the two tabs over to secure.
Step 4. Position appliance into prepared fram-
ing, secure with 6d nails at the nailing flange
along each side.
Step 5. Connecting Gas Line – Make gas line
connections. All codes require a shut-off valve
mounted in the supply line.
Figure 10 illus-
trates two methods for connecting the gas
supply. Installation methods and materials
must be in compliance with local codes.
The gas control valve is located in the lower
control compartment. To access the valve
open the lower control compartment door
(
Figure 11 ). The control valve has a ³⁄₈" NPT
thread inlet port and is fitted with a 3" (76 mm)
long nipple,
³⁄₈" NPT on both ends. Plan the
connections accordingly.
Route the gas line using techniques and mate-
rials prescribed by local and/or national codes.
If the gas line must be routed from the left hand
side (viewed from the gas controls), route the
gas line around the valve and connect to the
valve from the right hand side. The left hand
gas line opening has been offset to allow for
easy attachment of hard piping from the left
hand side, when hard piping (black iron) is
required by local codes. For ease in installa-
tion, the offset is designed to utilize (1) a 3/8"
street elbow at the valve, replacing the nipple
provided with the appliance and oriented to the
rear, (2) a 6", 3/8" nipple and (3) a 3/8" standard
elbow returning to the left and aligning with a
gas line routed through the left hand opening.

Secure all joints tightly using appropriate tools
and sealing compounds (ensure propane re-
sistant compounds are used in propane appli-
cations). Turn on gas supply and test for gas
leaks using a soapy water solution. Never use
an open flame to check for leaks.
A. Mix a 50% dish soap, 50% water solution.
B. Light the appliance (refer to safety and
lighting instructions on page 15) (
See *Note).
C. Brush all joints and connections with the
soapy water solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the “OFF” position.
Either tighten or refasten the leaking connec-
tion and retest as described above.
D. When the gas lines are tested and leak free,
observe the individual tongues of flame on the
burner. Make sure all ports are open and pro-
ducing flame evenly across the burner. If any
ports are blocked, or partially blocked, clean
out the ports.
An external regulator must be used on all
propane (L.P.G.) heaters, in addition to the
regulator fitted to the heater, to reduce the
supply tank pressure to 13" w.c. (maximum).
WARNING: CONNECTING DIRECTLY TO
AN UNREGULATED PROPANE TANK CAN
CAUSE AN EXPLOSION.
Step 6. Installing the Optional Remote Wall
Switch – The standard millivolt system comes
from the factory wired as shown in
Figure 12.
Select a convenient location for the remote wall
switch and connect the wiring to the appliance
(
Figure 13 ).
