Gas Plumbed on Left Hand Side of Fireplace
NOTE: Your gas log set is assembled at the factory to be installed in a fireplace plumbed with the gas
on the right side (facing). If your fireplace is plumbed with the gas on the left side, you may remove the
u-burner tube from the burner pan by removing the 3/4” knockout at the left back of the burner pan and
reinstalling the u-burner tube 180 degrees from its original position. You may also run a flexible connec-
tor (or as per local codes) along the back wall of the fireplace to bring your gas line to the right hand
side. You can then place the set in front of the flexible connector.
Damper Stop Installation:
For Use with BR, BC, SR, SC, TF and TL Series CFM Specialty Home Products Fireplaces
This Damper Stop is designed to work on all CFM
Specialty Home Products BR, BC, SR, SC, TF and
TL series fireplaces. For all other fireplaces, refer
to Page 6.
When installing a decorative gas appliance in a
fireplace, some local codes require this Damper
Stop to be used so the Damper will not close
completely. To install the Damper Stop:
The Damper Locking Bracket is already installed
on all BR, BC, SR, SC, TF and TL fireplaces.
Locate the Damper Locking Bracket on the left
side of the fireplace’s Combustion Dome. (Fig. 1)
With the Damper open, align the two slots on
either side of the cut-out on the Damper Stop with
the two small holes on the angled portion of the
Damper Locking Bracket. Attach the Damper Stop
with the Screws provided, as shown in Figure 2.
NOTE: Some of the early fireplace units may not
have the holes in the end of the Damper Locking
Bracket. If this is the case, use the Damper Stop
as a template to drill two (2) 1/8” holes in the
Damper Locking Bracket to mount the Damper
Stop.

Damper Stop Installation:
For Use With All Other Fireplaces
The Damper Stop provided keeps your damper
from accidentally closing during operation of your
set. This Damper Stop must be installed onto
your Damper at all times. NOTE: The damper
clamp is designed to hold the damper plate
open 3 inches. However, the damper must be
fully open when the log set is in operation.
Install the Damper Stop onto the edge of the
damper plate. Attach by securing the bolt pro-
vided to the damper plate with an adjustable
wrench. (Fig. 3)
If the Damper Stop does not fit, drill a 1/4” hole
into the damper plate and install an
anchor bolt with nut, at a 90 degree angle, so that
the damper plate will remain fully open.
The proper finished installation of the Damper
Stop is shown in Figure 4. If the bolt fails to block
the damper in an open position, the damper
should be removed from the chimney.
To check your vent for proper drafting: Light a
tightly rolled newspaper on one end and place it at
the inside front edge of the fireplace. Observe the
smoke and be sure the vent is properly drawing it
up the chimney. If the smoke is drawn

Connection to Gas Supply
1. Place the burner pan in the fireplace. The
burner pan should be located several inches
form the back wall, centered from left to right.
NOTE: This is for burner connection purposes
only. Exact burner placement will be covered on
page 8, after all connections have been made.
2. Attach the gas supply fitting onto your
fireplace’s gas supply pipe. (Fig. 5)
3. Attach one end of the flexible gas connector to
the brass burner inlet fitting which has been
factory installed into the burner.
4. Attach the other end of the gas connector to the
flared side of the gas supply fitting.
Remember to use pipe thread sealant or teflon tape only on the straight pipe threads. Do not use
any on flared ends.
Leak Test Procedures
Create a mixture of equal parts soap and water. Apply to all the joints of the pipe fittings from the gas
supply pipe to the burner. Turn on the gas supply valve for no longer than 3-5 seconds. If bubbles appear in
the soap solution applied to the joints, there is a leak. Turn off gas supply valve and tighten those fittings.
Repeat the above procedure until no bubbles appear in the soap solution. Remember to test all joints.
WARNING: DO NOT USE AN OPEN FLAMETO TEST FOR LEAKS!
NOTE: Always perform a leak test any time the appliance has been moved or disconnected from the gas
supply line.
Adding Pan Material
1. Open the bag of silica sand and spread it
evenly across the burner pan, to the top, as
shown in Figure 6. You may overflow the front
and sides of the pan to cover the entire pan and
connecting hardware. NOTE: Sand is for use
with Natural Gas ONLY! Vermiculite or lava
rock must be used in place of sand for propane
gas. See propane Conversion Kit manual for
details.
2. Next, open the bag of glowing embers and
place them on top of the silica sand evenly
across the burner pan. Be sure to separate
the glowing embers into very small pieces
before placing them onto the silica sand.

Grate and Log Placement
1. Place the grate over the burner pan so the front legs
of the grate are parallel to the front edge of the pan.
(Fig. 7)
2. Place the larger bottom logs onto the grate, leaving
as much space between them as possible. When
burning, the flames should come up directly between
the logs.
3. Place the smaller top logs diagonally onto the
bottom logs. The top logs can be arranged to
achieve your desired flame pattern. Be sure you
leave as much open space between the logs as
possible to minimize flame impingement and
sooting.
4. Open the bag of lava rock and spread the rocks onto
the fireplace floor around the burner pan for decora-
tive purposes.
Attach fettle to front of grate as shown in Figure 8.

FORYOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these directions exactly, a fire or explosion may result causing
property damage, personal injury or loss of life.
WHAT TO DO IFYOU SMELL GAS
•Do not try to light any appliance
•Do not touch any electrical switch, do not use any phone in your building
•Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.
•If you cannot reach your gas supplier, call the fire department
Lighting Instructions
1. Turn the gas shut-off valve to OFF.
2. Wait five (5) minutes to clear out any gas. If you
then smell gas STOP! Follow the safety information
on above. If you do not smell gas, go on to the next
step.
3. Light a match and lay it on top of the pan material,
about 2” from the end of the supply side of the pan.
(Fig. 8)
4. Slowly turn the gas shut-off valve ON until the
burner ignites. If the burner does not ignite within
ten (10) seconds with the match burning, turn the
shut-off valve OFF and repeat steps 1 through 4
again.
WARNING: Flame may flare up when ignited. Keep hands and face away from firebox.
Operation and Maintenance
To Adjust the Flame:
Adjust the flame to the desired level by rotating the gas
valve counterclockwise to open or clockwise
to close.
To Turn the Appliance OFF:
Rotate the gas shut-off valve clockwise to OFF.
Proper Maintenance:
Keep the area around the log set clean and clear of
debris.
Occasionally, you may use a soft bristle brush to clean
logs.
Once every year, a qualified agency or certified chim-
ney sweep should examine and clean the venting
system of the fireplace in which the log set is installed.
Appliance Break-In
During the 2-3 hour appliance break-in period, you may
detect an odor from the appliance as the various water-
based paints used in the manufacture of this log set
cure. This is a normal and temporary situation that is
not a cause for alarm. However, you may want to
provide extra ventilation to the room during this time.
To ensure proper curing of the logs:
1. Ignite a 2” flame and maintain it for 1/2 hour.
2. Burn the logs in consecutive 1/2 hour periods,
raising the flame an additional 2” to full flame height
for a total of three hours.

Troubleshooting
Log Set is Smoking / Sooting Excessively
It is natural and unavoidable for vented gas log sets to produce moderate levels of carbon (soot) where
flame contacts the logs. The logs can be cleaned using a soft-bristle brush. However, if soot is pro-
duced where there is no flame impingement, one of the following may be the cause:
Fireplace venting system not drafting properly: Make sure the damper is wide open at all times.
Preheat the flue in very cold weather by burning the log set at a very low level, then slowly increasing
the flame height over a matter of hours. Have the fireplace and the venting system professionally
cleaned.
Excessive flame impingement or blockage: Make sure there is proper spacing between the logs so
they are not smothering the flame. Rearrange the logs so they are touched less by the flames.
Excessive gas supply/pressure: Make sure the gas pressure coming into the fireplace does not
exceed the maximum pressure allowed with this gas set (refer to Tables on page 4). If you are using the
gas logs with a safety pilot kit, make sure you installed the correct orifice into the set.
Burner is Excessively Noisy
Please Note: The movement and combustion of gas will create low, unavoidable levels of noise.
Excessive gas pressure: Make sure the gas pressure coming into the fireplace does not exceed the
maximum pressure allowed with this gas log set (refer to Table on Page 3). If you are using the gas
logs with a safety pilot kit, make sure you installed the correct orifice into the set.
Passage of air/gas across irregular surfaces: There may be burrs, paint or other blockages on the
burner bar ports. Check these ports and remove any blockage.
Gas Connector: Relieve any tight bends or kinks in the flexible gas connector. Switch to a smooth
aluminum gas connect, which can be purchased at any hardware or home improvement store.
Burner Flame is Too High (8-12” AboveTop Logs) or Too Low (BelowTop Logs)
Incorrect gas supply, pressure or burner orifice used: Make sure the gas pressure coming into the
fireplace falls between the minimum and maximum pressures allowed with this gas set (refer to Table
on Page 3). If you are using the gas logs with a safety pilot kit, make sure you installed the correct
orifice into the set.
Blocked ports (low flame only): Free the main burner orifice and burner bar ports of any burrs, paint
or other blockage.
