on the floor. IF YOU SMELL GAS, FOLLOW
INSTRUCTIONS ON THE COVER PAGE OF THIS
MANUAL.
Use only your hand to push in or turn gas control
knobs. Never use tools. If a knob will not push in or
turn by hand, don’t try to repair it. Call a qualified
professional service technician. Forcing any controls
or attempting repairs may result in fire or explosion.
For each of the lighting options described below,
adjust the gas flow to have the appearance and
flame height as shown in Figure 1. It is important to
have a flame that is balanced with glowing embers
on the bottom and flames that do not extend too
much above the logs. Observe the flames. The main
burner flames should be blue at the base and a
combination of blue/yellow at the body and the tips.
They should be 5” to 8” above the logs, with the
center flame being the tallest. Front flames in the
ember burner should be ¼” above the embers.
NOTE: The Regency burner system uses an Oxygen
Depletion Sensing (ODS) pilot as shown in Figure 2

(Millivolt Variable Control & Variable Electronic).
When starting the ODS pilot, follow the instructions
that pertain to your log set model exactly.
The angle of the pilot flame touching the
thermocouple, as set by the factory, is very important
to maintain. The alignment and orientation of the
ODS pilot is slightly different when the burner is
equipped for Natural or Propane gas sources (Figure
3). This should be checked periodically while the
pilot is on.
Lighting Inst., Millivolt Variable Control
In this section, refer to Figure 4 for the gas valve and
Figure 5 for the remote control while doing the
following lighting steps for the Millivolt Variable
Control burner system:
1. Turn the Flame Height Control Knob (bottom
knob) clockwise as far as it will go to reach
the “OFF” position.
2. Verify that no gas is present around the
fireplace or burner area (this could take 5
minutes to clear if present).
3. If you still detect gas STOP! Then follow the
“WHAT TO DO IF YOU SMELL GAS”
instructions found on the cover page of this
manual.
4. Turn the Pilot Ignitor Knob (the top knob)
counterclockwise to the “IGN” (ignition)
position.

control receiver fails to operate, follow these steps to
light the fireplace manually:
1. Make sure the Main Valve Knob (bottom knob)
is fully clockwise to the OFF position.
2. Make sure the Manual Knob if fully clockwise
to the “MAN” position.
3. Make sure the “On/ Off” Switch is in the “O”
(OFF) position.
4. Verify that no gas is present around the
fireplace or burner area (this could take 5
minutes to clear if present).
5. If you still detect gas STOP! Then follow the
“WHAT TO DO IF YOU SMELL GAS”
instructions found on the cover page of this
manual.
6. Place On/Off Switch in the “I” (ON) position.
7. Using a pen or appropriate small tool, push the
Manual Pilot Valve all the way in and hold. This
starts the flow of gas to the pilot.
8. Note: When lighting the pilot, it may take as
much as 30 seconds for gas to reach the pilot.
9. While still pushing the Manual Pilot Valve, push
in the Piezo Ignitor to ignite the pilot.
10. Wait 10 seconds after the pilot is lit, then
release the Manual Pilot Valve.
11. If the pilot does not stay lit when you release
the Manual Pilot Valve, wait five (5) minutes and
repeat the above steps.
12. Turn the Manual Knob counterclockwise
until it is in the “ON” position.
13. Turn the Main Valve Knob all the way
counterclockwise to the “ON” position.
14. If the burner does not light STOP!, TURN
OFF GAS SUPPLY and get assistance from
qualified service personnel.
15. Use the Main Valve Knob to adjust the flame
to the desired height.

If you expect to not use the burner for an extended
period of time, turn the Main Valve Knob to the
“OFF” position, turn the Manual Knob to the “MAN”
position, and turn the On/Off Switch to the “O”
position. This will completely extinguish the ODS
pilot and main burner. Then shut off the gas supply
line valve to the fireplace.

product can cause serious personal injury,
property damage, or loss of life.
2. Some fireplaces (especially older ones) may
need repair prior to installing this appliance.
3. This appliance is only for use with the type of
gas indicated on the rating plate. This appliance
is NOT CONVERTIBLE for use with other
gasses.
4. CHECK GAS TYPE (Natural or L.P.): the gas
supply must be the same as stated on your
burner system rating plate. If the gas supply is
different, DO NOT INSTALL. Contact your
dealer for immediate assistance.
5. INSUFFICIENT GAS PRESSURE WILL KEEP
THE ODS (OXYGEN DEPLETION SENSOR)
PILOT FROM OPERATING PROPERLY. DO
NOT USE IF GAS PRESSURE IS LOWER
THAN THE MINIMUM REQUIREMENTS.
6. The minimum inlet gas-supply pressure for the
purpose of input adjustment is 5” water column
(w.c) on natural gas and 11” w.c. LP gas.
7. The maximum inlet gas-supply pressure is
10.5” w.c. on natural gas and 13” w.c. LP gas.
The LP source must be regulated. (Do not
connect this appliance directly to an
unregulated LP gas tank – this can cause an
explosion.) Do not connect this appliance to
a portable LP gas cylinder.
8. The gas piping system must be sized to
provide minimum pressure at the maximum
flow rate (BTU/Hr). Undue pressure loss will
occur if the pipe is too small, or the run is too
long. Gas supply piping must be ½” minimum
interior diameter. If the gas line is longer than
20’, a larger diameter line may be necessary.
Refer to the NFPA 54 guidelines for further
details.
9. Input ratings shown in BTU per hour are for
elevation up to 2,000 ft. For elevations above
2,000 ft., refer to the National Fuel Gas Code or
contact Regency before installing.
Burner System Requirements
Note: Installation in any other fireplace is prohibited
and will void any approvals and warranties.
This burner system is equipped with an Oxygen
Depletion Sensor (ODS) safety pilot system. The
BEFORE PROCEEDING, CAREFULLY READ
ALL OF THE IMPORTANT SAFETY
INFORMATION CONTAINED IN THIS
OWNER’S MANUAL, INCLUDING:
•Pre-Installation and Fireplace
Preparation Safety Guidelines
•Ventilation and Confined Space
Information
•Installation Safety Guidelines

ODS senses the amount of oxygen available in the
room and shuts the burner system off before the
oxygen level drops below 18%.
The pilot can only be relit when fresh air is available.
This may require opening a window or a door to
another room or cracking the damper open slightly.
This burner system has been certified to two
standards:
VENTED DECORATIVE APPLIANCE – ANSI Z21.60
UNVENTED ROOM HEATER – ANSI Z21.11.2
Vented Installation Restrictions
This unit may not be installed in a vented fireplace
with a chimney of less than 15 feet in height.
This burner system may be installed as a vented
decorative appliance in compliance with ANSI
Z21.60 and the national Fuel Gas Code, Section 6.6.
The minimum permanent free opening of the
fireplace chimney or chimney damper must be met
per the Chimney Vent Openings shown in Table 3.
To accomplish this, the chimney damper must be
fixed in a manner to maintain permanent free
opening at all times.
The damper clamp (See Figure 8) with bolt is
provided as a means to prevent the full closure of the
damper blade. The clamp is easily attached to most
damper blades with pliers or a wrench, and must be
permanently installed. The clamp is designed to
prevent accidental closure of the damper when
installed as pictured.
Should the clamp not fit, or fail to provide the
required permanent vent opening, do any of the
following:
•Have a permanent stop installed
•Remove the damper blade
•Install a screw or bolt on the edge of the
damper
•Drill holes in the damper
•Cut the damper providing the minimum
permanent opening required
This damper clamp is not required if the burner
system is installed as an unvented room heater.
Unvented Installation Restrictions
Check local or state codes to determine if vent-free
heaters are permitted in your locality before you
install this burner system as a vent-free appliance. If
not permitted, you may install and operate this
burner system as a vented appliance.
When installed as an unvented decorative gas
appliance, your vent-free gas burner system SHALL
NOT BE INSTALLED IN A CONFINED SPACE OR
UNUSUALLY TIGHT CONSTRUCTION unless
provisions are made for adequate combustion and
ventilation air.
Unusually tight construction is defined as:
1. Walls and ceiling exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating of 1 perm or less with
openings that are sealed or use gaskets;
2. Weather stripping has been added on openable
windows and doors; AND
3. Caulking or sealants are applied to areas such
as joints around window and door frames;
between sole plates and floors; between wall-
ceiling joints; between wall panels; at
penetrations for plumbing, electrical and gas
lines; and other openings.
Determining a Confined Space
•In general, the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 defines a confined space as
a space whose volume is less than 50 cu. Ft
Figure 8
Note: To install the unvented gas burner
system, the fireplace must have a gas-supply
line that has been installed by a qualified
professional service technician in
accordance with all local codes.

per 1,000 BTU per hour of the aggregate input
of all appliances installed in that space.
•An unconfined space is a space where the
volume is at least 50 cu. Ft. per 1,000 BTU per
hour of the aggregate input rating of all
appliances installed in that space.
•Rooms communicating directly with space in
which the appliances are installed, through
openings not furnished with doors, are
considered a part of the unconfined space.
WARNING: Do not install the unvented burner
system where the room is considered a confined
space.
To determine if the location that this burner system is
to be installed fits the definition of an unconfined
space, multiply in FEET the length of the room by the
width of the room by the height of the room then
multiply by 20. The result is the maximum BTU’s
allowed.
(Per Figure 9, calculate Length x Width x Height x 20
= Maximum BTU’s Allowed)
WARNING
If the area in which the heater may be operated is
smaller than that defined as an unconfined space of
if the building is unusually tight construction, provide
adequate combustion and ventilation air by one of
the methods described in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, Air Combustion and
Ventilation, or applicable local codes.

Installing in a Confined Space
If the space is smaller than the above formula allows,
and/or smaller than the diagrams, DO NOT install
the vent-free burner system unless provisions for
additional combustion and ventilation air are made.
IT MAY BE NECESSARY TO OPEN A WINDOW
SLIGHTLY (1”-2”) OR OTHERWISE INCREASE
VENTILATION. CONDITIONS REQUIRING THIS
INCLUDE, BUT ARE NOT LIMITED TO:
1. Installation in a CONFINED SPACE
2. Installation in a HOME OF UNUSUALLY TIGHT
CONSTRUCTION
3. Installation at HIGH ALTITUDES
4. Certain MEDICAL or PHYSICAL CONDITIONS
OF THE HOMEOWNER that may be adversely
impacted by combustion products created by
burning natural or propane gas.
Installation in a home with unusually tight
construction and / or installation at high altitudes
may cause your vent-free burner system to produce
excessive heat or excessive moisture. The oxygen
depletion sensor may shut down the burner system.
These conditions may be corrected by opening a
window or otherwise increasing the number of air
changes in the home.
This vent-free burner system has been certified to
function safely and reliably with emission by-
products well within acceptable safety and health
standards.
Your specific medical or physical condition may
render you more sensitive to products created by
burning natural gas or propane gas. If this is the
case, you should open a window or otherwise
increase ventilation.
Figure 9

Clearances to Combustibles
If the vent-free burner system is installed in a factory-
built fireplace, follow the manufacturer’s guidelines
for minimum clearances to combustibles.
In the absence of such guidelines, refer to the
illustration of clearances in Figure 10 and follow the
instructions below:
Note: Clearances to combustible construction are
those distances required to ensure that fireplace
mantels, facings, walls, ceilings, and flooring will not
catch fire.
In most cases, these clearances should also be
adequate to prevent discoloration or warping due to
heat. However, every gas burner installation
presents a different and unique set of circumstances
involving many variables beyond the control of the
manufacturer.
These include paint or finish composition, previous
exposures to heat, methods and quality of
construction, air flow patterns, glass doors, fans or
blowers, etc.
Because of these variables, we cannot guarantee
that heat warping or discoloration will never occur.
The potential for heat warping or discoloration may
exist no matter what item(s) you are burning in the
fireplace, including wood.
These dimensions are MINIMUM CLEARANCES to
maintain when you install this burner system. The
fireplace opening MUST BE AT LEAST 6” from any
combustible sidewall. The ceiling MUST BE AT
LEAST 42” from the top of the fireplace opening.
Clearance IN FRONT
Be certain that combustible flooring material (i.e.
carpet, tile, etc.) is not too close to the vent-free unit.
If the vent-free burner system is at floor level or
less than 6” above the floor, there MUST be at
least 12” (1 foot) of noncombustible material
between the front of the fireplace and any
combustible flooring.
Clearance ABOVE
To install the vent-free burner system, there must
ALWAYS be noncombustible or heat resistant
material immediately above the fireplace opening.
Heat resistant material (i.e. marble, or slate) must be
at least 5/8” thick. Sheet metal should not be
installed onto combustible materials.
If you DO NOT install a fireplace hood, there MUST
be at least 12” of noncombustible or heat resistant
material immediately above the fireplace opening.
If you DO install a fireplace hood, there MUST be at
least 10” of noncombustible or heat resistant material
immediately above the fireplace opening.
If there is a wooden mantel, shelf or other
combustible projection above the fireplace, follow the
clearances information in Figure 11 in this manual.
A fireplace hood deflects heat away from the
fireplaces face and mantel, reducing the potential for
heat related warping or discoloration. The use of a
fireplace hood is highly recommended.
DO NOT place any combustible decorations/items
on the mantel or above the fireplace.
Clearances to Combustible Construction:
Sidewalls: 6” from side of fireplace opening.
Ceiling: 42” from top of fireplace opening.
Flooring: See 5.6.1 CLEARANCE IN FRONT.
Mantel:
See 5.6.2 CLEARANCE ABOVE.
Figure 10
IF YOU CANNOT MEET THESE MINIMUM
CLEARANCES, YOU M
UST OPERATE THE
VENT-
FREE BURNER SYSTEM WITH THE
CHIMNEY FLUE DAMPER OPEN.
