• Horizontal run must never exceed 50% of the height
of the vent system. Horizontal runs are measured
center pipe to center pipe.
• Horizontal runs must have a minimum 1/4” rise per
foot and may not run level or down hill.
Attaching 4” Flue to BBV:
• The first section of B-vent flue should overlap
the appliance collar. The appliance collar may be
crimped to ease the installation of the first section
of flue.
• Do not penetrate the pipe inner liner with sheet met-
al screws. Attach the initial flue section to the top
of the firebox chassis with 1/4” self-tapping screws
and plumbers strap. Attach the strap toward the
bottom of the flue section and pull taut for proper
tension to the firebox.
Attaching 6” Flue to SBV:
• The 6” appliance collar is slightly larger that the in-
ner wall of most B-vent 6” pipe sections. Install the
first section of B-vent by slipping the flue’s inner
wall tot he inside of the appliance collar. The B-vent
outer wall will slip to the outside of the appliance
collar.
• Do not penetrate the pipe inner line with sheet met-
al screws. Attach the initial flue section tot he top
of the firebox chassis with 1/4” self-tapping screws
and plumber’s strap. Attach the strap toward the
bottom of the flue section and pull taut for proper
tension to the firebox.
Support the Pipe
• Support horizontal runs a minimum of every five (5)
feet. Refer to vent manufacturer’s instructions for

NOTE: The use of outside air for combustion is optional unless required by building
codes. It is only necessary to supply outside
combustion air to one side of fireplace. Use
model OAC4 combustion air kit (refer to Page
17).
1. Avoid extremely long runs and numer-
ous turns in duct leading from fireplace
to combustion air assembly. These conditions increase the resistance to free flow
of air through duct. Figures 9 and 10
2. Locate combustion air assembly at an
exterior location. Make sure the location
cannot be accidentally blocked. Locate
assembly above snow line to prevent
snow from blocking assembly.
3. Never mount combustion air inlet assem-
bly in garage or storage area where combustible fumes (gasoline) might be drawn
into fireplace.
4. Combustion air may be drawn from crawl
space under house when adequate supply of air is provided by open ventilation.

FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the fireplace you are installing. If you have conflicting gas types, do not
install fireplace. See dealer where you purchased the fireplace for proper fireplace for your gas
type.
INSTALLING GAS PIPING TO FIREPLACE LOCATION
INSTALLATION ITEMS NEEDED
Before installing, make sure you have the items listed below:
• External regulator (supplied by installer) • Tee Joint
• Piping (check local codes) • Pipe wrench
• Sealant (resistant to propane/LP gas)
A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.
WARNING
• Test gauge connection*
• Sediment trap (optional but recommended)
• Approved flexible gas line with gas connector (if allowed by
local codes - not provided)
*A CSA design-certified equipment shutoff valve with 1/8”
NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff
valve from your dealer.
For propane/LP connections only, the installer must supply an external regulator. The external
regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between
11 and 13 inches of water. If you do not reduce incoming gas pressure, burner system regulator
damage could occur. Install external regulator with the vent pointing down as shown in Figure 14.
Pointing the vent down protects it from freezing rain or sleet.
For propane/LP units, never connect
fireplace directly to the propane/LP
supply. This burner system requires an
external regulator (not supplied). Install
the external regulator between the burn-

IMPORTANT: Install main gas valve (equipment shut-off valve) in an accessible locations. The main
gas valve is for turning on or shutting off the gas to the fireplace.
Check your building codes for any special requirements for
locating equipment shut-off valve to fireplaces.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant form going into pipe. Excess sealant in
pipe could result in clogged burner system valves.
We recommend that you install a sediment trap/drip leg in
supply line as shown in Figure 15. Locate sediment trap/drip
leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system.
Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into the burner system gas controls. If sediment
trap/drip leg is not installed or is installed wrong, burner system may not run properly.

STANDING PILOT IGNITION
TROUBLESHOOTING
SYMPTOM
1. Spark igniter
will not light pilot after repeated triggering of
piezo.
2. Pilot will not
stay lit after
carefully following lighting
instructions.
3. Pilot burning,
valve knob
tuned to “ON”,
switch is turned
to “ON” or “RS”,
but burner will
not ignite.
POSSIBLE CAUSE
A. Wire disonnected.
B. Defective igniter.
C. No gas or low gas
pressure.
D. No Propane/LPG in
tank.
A. Defective thermocou-
ple.
B. Defective valve.
A. Defective switch, wall
switch, remote control
or wire.
B. Pilot flame too small.
C. Defective or malfunc-
tioning thermopile.
D. Defective valve.
ACTION
A. Open door and check to make sure wire is connected to
igniter.
B. Check for spark at electrode and pilot. If no spark and elec-
trode wire is properly connected, replace pilot assembly.
C. Check remote/manual shut-off valve from fireplace. Low
pressure can be caused by bent lines, restricted lines, low
pressure line pressure. Consult with plumber or gas supplier.
D. Check Propane/LPG tank. Refill tank.
A. Check that thermocouple flame impinges on thermocouple.
Clean and/or adjust pilot for maximum flame impingement.
Ensure that the thermocouple connection at the gas valve is
fully inserted and tight.
Disconnect the thermocouple from the valve, place one mil-
livolt lead wire on the tip of the thermocouple and the other
meter lead wire on the thermocouple copper lead. Start the
pilot and hold the valve knob in. If the millivolt reading is less
than 15m V, replace pilot assembly.
B. If thermocouple is producing more than 15m V, replace faulty
valve.
A. Check switch and wire for proper connection. Place jumper
wires across terminals of switch. If burner comes on, replace
defective switch. If the switch is OK, repeat the same procedure on remote control. If burner comes on, replace remote
control. Place jumper wire across wire at gas valves (terminals marked TH and TP/TH). If burner comes on, wires are
faulty or connections are bad. Replace wire.
B. If pilot flame is not close enough to the thermopile, adjust
pilot flame.
C. Check thermopile wire connections to make sure all are tight
and that the thermopile is fully inserted into pilot assembly.
Check thermopile with a millivolt meter. Connect leads to TP
and TP/TH terminals on the control valve. If meter reading is
below 325m V, replace pilot assembly.
D. Turn valve knob to “ON” and switch to “ON”. Take a reading
at the thermopile leads (TP & TP/TH) on the valve. If the meter reads greater than 175m V and the burner does not light,
replace defective valve.
4. Frequent pilot
outage problem.
5. The pilot and
main burner
extinguish while
in operation.
32
A. Pilot flame may be too
high or too low, causing pilot safety to drop
out.
A. Inner vent pipe leaking
exhaust gases back
into system.
B. Horizontal vent improp-
erly pitched.
C. Improper vent cap
installation.
A. Clean and adjust the pilot flame for maximum flame impinge-
ment on thermocouple.
A. Check for flue product leak. Replace defective pipe section.
B. Check horizontal-vent piping is running upward 1/4” per foot.
Do not run the pipe level or downward.
C. Check for proper installation and freedom from debris or
blockage.
