INSTALLATION

UNIT ASSEMBLY

PRIOR TO

INSTALLATION

The Top Facing Support, the Side Nailing Strips
and the 2 Top Standoffs must be correctly
positioned and attached to the top before unit
is slipped into position.

INSTALLATION

TOP STANDOFF ASSEMBLY

The top standoffs are shipped in a fl at position
and must be folded into shape and attached.

1) Remove the standoffs from the fi replace

top.

2) Take each standoff and bend into the correct

shape. Bend up at the bend lines until the
screw holes in the standoff and the pre­punched screw holes on the fi replace top
line up.

3) Attach the standoff securely to the top

with 2 screws per standoff (on opposite
corners).

SIDE NAILING STRIPS

The side nailing strips come attached to the unit.
There are 3 plates, one on the top and bottom
that can be folded out as required.

Side Nailing Strips shown folded out.

FINISHING TEMPLATE

In order to maintain a clean face; the L900
allows for a 1/8” in overlap of fi nishing material,
such as rock or tile, on both the left and right
hand sides of the unit (top and bottom sides do
not allow for an overlap), this overlap must not
be exceeded or the glass door will no longer
open properly.

Non-combustible wall board is installed up
to the fl anges on all sides of the unit. When
installing any additional facing material use
the Finishing Template (included with the unit)
to ensure that the fi nishing material does not
exceed the allowable overlap.

The Finishing Template uses two magnets to
attach itself to the fl ange on the left or right side
of the unit (see diagram below). Install the facing
material up to the outside edge (when facing
the unit) of the fi nishing template. This template
may be discarded after the facing material has
been installed.

Regency® L900 Direct Vent Gas Fireplace

INSTALLATION

VENTING

INTRODUCTION

The L900 uses the "balanced fl ue" technology
Co Axial system. The inner liner vents products
of combustion to the outside while the outer
liner draws outside combustion air into the
combustion chamber thereby eliminating the
need to use heated room air for combustion and
losing warm room air up the chimney.

Note: These flue pipes must not be

connected to any other appliance.

The gas appliance and vent system must be
vented directly to the outside of the building,
and never be attached to a chimney serving a
separate solid fuel or gas burning appliance.
Each direct vent gas appliance must use it's own
separate vent system. Common vent systems
are prohibited.

VENT RESTRICTOR

POSITION

Vent restriction is required for certain venting
installations, see the diagrams in the "Venting
Arrangements" section to determine if they are
required for your installation.

To set the vent restriction as indicated in the
venting arrangements diagrams, refer to the
instructions below;

1) Remove the glass door.

a. Release the 2 door latches on the left

RIGID PIPE VENTING SYSTEMS

BASIC HORIZONTAL & VERTICAL TERMINATIONS

Rigid Pipe Vent Systems offer a complete
line of component parts for installation of both
horizontal and vertical installations. Many items
are offered in decorative black, as well as gal­vanized fi nish.

INSTALLATION

The minimum components required for a basic
horizontal termination are:

1 AstroCap XL
1 90o Elbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness

The minimum components required for a basic
vertical termination are:

1 Vertical Termination Cap
1 Rigid Pipe Adaptor
1 Lengths of pipe to adequately
penetrate roof
1 Ceiling Firestop
1 Flashing
1 Storm Collar

Wall thickness is measured from the back
standoffs to the inside mounting surface of
termination cap. For siding other than vinyl
furring strips may be used, instead of the vinyl
siding standoff, to create a level surface to
mount the vent terminal. The Terminal must
not be recessed into siding. Measure the wall
thickness including furring strips.

UNIT INSTALLATION

WITH HORIZONTAL

TERMINATION

(Rigid Vent Systems)

A top clearance of 3"(76mm) and side & bottom
clearance of 2"(51mm) must be maintained;
except when passing through a wall, ceil­ing, or at the termination where the use of a
fi restop or wall thimble reduces the required
clearance to 1-1/2" (38mm). We recommend
framing a 11"(279mm) x 11"(279mm) (inside
dimensions) hole to give structural rigidity
for mounting the termination.

Install the vent system according to the
manufacturer's instructions included with the
components.

1) Set the unit in its desired location. Check to

determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust
the location of the unit. Rough in the gas
preferably on the right side of the unit and
the electrical (junction block is on the left
side) on the left.

2) Direct Vent pipe and fi ttings are designed with

special twist-lock connections to connect the
venting system to the appliance fl ue outlet.
A twist-lock appliance adaptor is required.

3) In conjunction with the Simpson Dura-Vent

Direct Vent GS system. Install the adaptor
after the unit is set in its desired location.
Put a bead of high temperature silicone
inside the outer section of the adapter and
a bead of Mill Pack on the inner collar. Slip
the adapter over the existing inner and outer
fl ue collar. Fasten to the outer collar only with
the 3 supplied screws (drilling pilot holes will
make this easier).

4) Level the fi replace and fasten it to the framing

using nails or screws through the top and
side nailing strips.

5) Assemble the desired combination of pipe

and elbows to the appliance adaptor and
twist-lock for a solid connection.

Note: For best results and optimum

performance with each approved
venting system, it is highly
recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe
connection. Failure to do so may result
in drafting or performance issues not
covered under warranty. Silicone (red
RTV) is optional.

Horizontal runs of vent must be supported
every 3 feet (0.9meter). Wall straps are
available for this purpose.

6) Mark the wall for a 11" x 11" (279mm x

279mm) square hole. The center of the
square hole should line up with the center­line of the horizontal pipe. Cut and frame the
11 inch (279mm) square hole in the exterior
wall where the vent will be terminated. See
diagram 2 for center line requirements.

If the wall being penetrated is constructed of

non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole
is acceptable.

Diagram 2

Note:
a) The horizontal run of vent must be level,

or have a 1/4 inch rise for every 1 foot
of run towards the termination. Never
allow the vent to run downward. This
could cause high temperatures and may
present the possibility of a fi re.

b) The location of the horizontal vent

termination on an exterior wall must meet
all local and national building codes, and
must not be blocked or obstructed. See
"Exterior Vent Termination Locations"
section for more details.

7) Ensure that the pipe clearances to

combustible materials are maintained
(Diagram 5). Install the termination cap.

Note: If installing termination on a vinyl

siding covered wall, a vinyl siding
standoff or furring strips must be used
to ensure that the termination is not
recessed into the siding.

Diagram 5

The four wood screws provided should be re-

placed with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.

8) Before connecting the horizontal run of vent

pipe to the vent termination, slide the Wall
Thimble over the vent pipe. The wall thimble
is required for all horizontal terminations.

9) Slide the appliance and vent assembly

towards the wall carefully inserting the vent
pipe into the vent cap assembly. It is important
that the vent pipe extends into the vent cap
suffi cient distance so as to result in a minimum
pipe overlap of 1-1/4 inches (32mm). Secure
the connection between the vent pipe and
the vent cap.

10) Install wall thimble in the center of the 11"

(279mm) square and attach with wood screws
(Diagram 7).

Diagram 7

NOTE: A Vent Guard is required when
the AstroCap is installed above grade
at 7 feet or lower.

TERMINATION

(Rigid Vent Systems)

Note: A clearance of 2"(51mm) must be

maintained; except when passing
through a wall, ceiling, or at the

INSTALLATION

termination where the use of a fi restop
or wall thimble reduces the required
clearance to 1-1/2" (38mm). We
recommend framing a 11"(279mm) x
11"(279mm) (inside dimensions) hole
to give structural rigidity for mounting
the termination.

1) Maintain the 2" (51mm)

clearances (air spaces)
to combustibles when
passing through ceilings,
walls, roofs, enclosures,
attic rafter, or other nearby
combustible surfaces.
Do not pack air spaces
with insulation. Check
"Venting Arrangemnt

- Vertical Termination"
section for the
maximum vertical rise
of the venting system and
the maximum horizontal
offset limitations.

2) Set the gas appliance

in its desired location.
Drop a plumb bob
down from the ceiling
to the position of the
appliance fl ue exit,
and mark the location
where the vent will
penetrate the ceiling.
Drill a small hole at
his point. Next, drop
a plumb bob from
the roof to the hole
previously drilled in
the ceiling, and mark
the spot where the
vent will penetrate the roof. Determine if ceiling
joists, roof rafters or other framing will obstruct
the venting system. You may wish to relocate
the appliance or to offset, as shown in Diagram
2 to avoid cutting load bearing members.

3) A Firestop spacer must be installed in the fl oor

or ceiling of every level.

Diagram 3

Diagram 2

Diagram 1

4) Assemble the desired lengths of pipe and

elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.

Note:
For best results and optimum performance
with each approved venting system, it is
highly recommended to apply “Mill-Pac”
sealant (supplied) to every inner pipe connec­tion. Failure to do so may result in drafting
or performance issues not covered under
warranty. Silicone (red RTV) is optional.

5) Cut a hole in the roof centered on the small

drilled hole placed in the roof in Step 2. The
hole should be of suffi cient size to meet
the minimum requirements for clearance to
combustibles of 1-1/2"(38mm). Slip the fl ashing
under the shingles (shingles should overlap
half the fl ashing) as per Diagram 4.

Diagram 4: The upper half of the fl ashing is

installed under the roofi ng material and not

nailed down until the chimney is installed.

This allows for small adjustments.

6) Continue to assemble pipe lengths.

Note: If an offset is necessary in the attic

to avoid obstructions, it is important
to support the vent pipe every 3
feet (0.9 meter), to avoid excessive
stress on the elbows, and possible
separation. Wall straps are available
for this purpose

(Diagram 2).

Galvanized pipe is desirable above the roofl ine

due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until
the height of the vent cap meets the minimum
height requirements specifi ed in Diagram 5 or
local codes. Note that for steep roof pitches,
the vertical height must be increased.

Diagram 5

over 16/12 to 18/12 7 2.13

over 18/12 to 20/12 7.5 2.29

A poor draft, or down drafting can result from

high wind conditions near big trees or adjoining
roof lines, in these cases, increasing the vent
height may solve the problem.

7) Ensure vent is vertical and secure the base

of the fl ashing to the roof with roofi ng rails,
slide storm collar over the pipe section and
seal with a mastic.

8) Install the vertical termination cap by twist-

locking it.

Note: Any closets or storage spaces, which

the vent passes through must be
enclosed.

HORIZONTAL TERMINATION

WITH FLEX VENT SYSTEM

Note: A top clearance of 3"(76mm) and

side & bottom clearance of 2"(51mm)
must be maintained; except when
passing through a wall, ceiling, or
at the termination where the use of
a fi restop or wall thimble reduces the
required clearance to 1-1/2" (38mm).
We recommend framing a 11"(279mm)
x 11"(279mm) (inside dimensions)
hole to give structural rigidity for
mounting the termination.

1) Locate the unit in the framing, rough in the

gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut an 11"(279mm) hole in the wall (inside
dimension).

4) Separate the 2 halves of the wall thimble and

securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
for 2 x 4 or 2 x 6 walls.

5) Slip the assembled liner and termination

assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.

6) Pull the centre 5"(127mm) liner and outer
8"(203mm) liner out enough to slip over

the fl ue collars of the fi replace. (You may
wish to cut the liner shorter to make it more
workable.) Do not bend liner more than 90

The liners must slip over the collars a
minimum of 1-3/8".

7) Apply Mill Pac over the fi replace inner collar

and slip the 5"(127mm) liner down over it
and attach with 3 supplied screws.

8) Do the same with the 8"(203mm) liner.

o

IMPORTANT: Do not locate termination
hood where excessive snow or ice
buildup may occur. Be sure to check vent
termination area after snow falls, and clear
to prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.

INSTALLATION

Note: If installing termination on a siding

covered wall, a vinyl siding standoff
or vinyl furring strips must be used
to ensure that the termination is not
recessed into the siding.

2) Level the fi replace and fasten it to the fram-

ing using nails or screws through the nailing
strips.

3) Assemble the vent assembly by applying

Mill Pac to the 5"(127mm) inner collar of
the termination and slipping the 5"(127mm)
liner over it at least 1-3/8" (35mm). Fasten
with the 3 screws (drilling pilot holes will
make this easier). Apply Mill Pac or high
temperature silicone to the 8"(203mm) fl ex
pipe and slip it over the 8" outer collar of
the vent terminal at least 1-3/8"(35mm) and
fasten with the 3 screws.

NOTE: Horizontal sections must be sup-

ported at intervals not exceeding 3
feet (0.9 meter). (Flame picture and
performance will be affected by sags
in the liner).

9) Apply a bead of silicone between the thimble

and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.

HIGH ELEVATION

This unit is approved in Canada for altitude 0
to 4500 ft. (CAN1 2.17-M91).

GAS LINE

INSTALLATION

Since some municipalities have additional
local codes it is always best to consult with
your local authorities and the CAN/CGA B149
installation code.

For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.

When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
connectors are usually considered to meet this
requirement.

IMPORTANT: Always check for gas leaks
with a soap and water solution or gas leak
detector. Do not use open fl ame for leak
testing.

PILOT ADJUSTMENT

Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).

Note: If you have an incorrect fl ame pattern,

contact your Regency® dealer for
further instructions.

Incorrect fl ame pattern will have small,
probably yellow fl ames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.

GAS PIPE PRESSURE

TESTING

The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig.
(3.45 kPa). Disconnect piping from valve at
pressures over 1/2 psig.

Note: To properly check gas pressure, both

inlet and manifold pressures should
be checked using the valve pressure
ports on the valve.

1) Make sure the valve is in the "OFF"

position.

2) Loosen the "IN" and/or "OUT" pressure

tap(s), turning counterclockwise with a

1/8" wide fl at screwdriver.

3) Attach manometer to "IN" and/or "OUT"

pressure tap(s) using a 5/16" ID hose.

4) Light the pilot and turn the valve to "ON"

position.

5) The pressure check should be carried out

with the unit burning and the setting should
be within the limits specifi ed on the safety
label.

6) When fi nished reading manometer, turn

off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8" fl at
screwdriver. Note: Screw should be snug,

but do not over tighten.

OPERATING INSTRUCTIONS

MATCHING REMOTE

HANDSET & CONTROL

BOX ID CODE

The Remote Control Handset has a set of
unique ID codes that is pre-programmed into its
memory. This set of ID codes helps to differenti­ate one Remote Control Handset from another
so that only the control box with a matching ID
code will respond to the appropriate Remote
Control Handset.

To ensure the remote control is matched to
the receiver correctly, please follow the steps
below:

1. Ensure that the Remote Control and the

3-way switch located at the appliance are
both in the OFF position.

2. Ensure that the pilot is lit and the pilot

control knob is in the ON position on the
appliance.

3. Install the 2 x AAA alkaline batteries into the

Remote Control.

4. Unplug and re-plug the power cord. The

power cord is located on the left hand side
of the appliance and will be plugged into the
receptacle.

5. Switch the 3-way switch located on the ap-

pliance to the REMOTE position.

6. Press and hold the PROG and FAN buttons

simultaneously for up to 20 seconds. During
this time, the remote will display LC while it
is transmitting codes to the receiver. Once
it is successfully transmitted, one will hear
the solenoid click and the burners will come
on. If is does not work the fi rst time, repeat
steps 1 - 6.

OPERATING

INSTRUCTIONS

1) Read and understand these instructions

before operating this appliance.

2) Check to see that all wiring is correct and

enclosed to prevent possible shock.

3) Check to ensure there are no gas leaks.

4) Make sure the glass in the door frame is

properly positioned. Never operate the
appliance with the glass removed.

5) Verify that the venting and cap are

unobstructed.

6) Ensure that the brick panels are installed.

7) Verify log placement. If the pilot cannot be

seen when lighting the unit, the logs have
been incorrectly positioned.

8) The unit should never be turned off, and on

again without a minimum of a 60 second
wait.

FIRST FIRE

The FIRST FIRE in your heater is part of the paint
curing process. To ensure the paint is properly
cured, it is recommended you burn your fi replace
for at least four (4) hours the fi rst time.

When fi rst operated, the unit will release an
odour caused by the curing of the paint and the
burning off of any oils remaining from manufac­turing. Smoke detectors in the house may go off
at this time. Open a few windows to ventilate
the room for a couple of hours. The glass may
require cleaning.

DO NOT BURN THE APPLIANCE
WITHOUT THE GLASS FRONT IN
PLACE.

DO NOT ATTEMPT TO CLEAN THE
GLASS WHILE IT IS STILL HOT!

During the fi rst few fi res, a white fi lm
may develop on the glass front as part of
the curing process. The glass should be
cleaned after the unit has cooled down
or the fi lm will bake on and become very
diffi cult to remove. Use a non-abrasive
cleaner and DO NOT ATTEMPT TO CLEAN
THE GLASS WHILE IT IS HOT.

LIGHTING

PROCEDURE

IMPORTANT
To ignite or reignite the pilot, you
must fi rst remove the glass door.

Only when the pilot holds, without pressure
being applied to the control knob, resecure the
glass door to the unit. The unit must not be
operated with the glass door removed.

IMPORTANT Gas on/off knob cannot be
turned from "PILOT" to "OFF" unless it is
partially depressed.

Ensure that the 3 way switch on the manual
control panel is in the "Remote" position.

The manual control panel is located on the left
hand side of the fi rebox behind the left side
exterior brick panel.

OPERATION

7. Release both the PROG and FAN buttons.

The remote will revert back to normal, but
the burner will still be on.

8. Press the ON/OFF button on the remote

control 2 times to turn the burner off.

9. The remote control is now programmed to

the receiver and the appliance can now be
operated with it.

The control box will only learn the Remote ID
codes during the fi rst 30 seconds after power
is applied and will ignore this special command
from the Remote after the fi rst 30 seconds.

NOTE: This must only be performed by a quali­fi ed installer.

Regency® L900 Direct Vent Gas Fireplace 39

NOTE: The main burner will always start on

"HIGH" and resume it's last setting after
20 seconds of operation.

NOTE: When the glass is cold and the appliance

is lit, it may cause condensation and fog
the glass. This condensation is normal
and will disappear in a few minutes as
the glass heats up.

NORMAL OPERATING

SOUNDS OF

GAS APPLIANCES

It is possible that you will hear some sounds
from your gas appliance. This is perfectly normal
due to the fact that there are various gauges
and types of steel used within your appliance.
Listed below are some examples. All are normal
operating sounds and should not be considered
as defects in your appliance.

Burner Tray:

The burner tray is positioned directly under the
burner tube and logs and is made of a different
gauge material from the rest of the fi rebox and
body. Therefore, the varying thicknesses of steel
will expand and contract at slightly different
rates which can cause "ticking" and "cracking"
sounds. You should also be aware that as there
are temperature changes within the unit these
sounds will likely re-occur. Again, this is normal
for steel fi reboxes.

Pilot Flame:

While the pilot fl ame is on it can make a very
slight "whisper" sound.

Gas Control Valve:
As the gas control valve turns ON and OFF, a
dull clicking sound may be audible, this is normal
operation of a gas regulator or valve.

Unit Body/Firebox:
Different types and thicknesses of steel will
expand and contract at different rates resulting
in some "cracking" and "ticking" sounds will be
heard throughout the cycling process.

OPERATION DURING

POWER OUTAGE

Important:

If the unit is not used for a prolonged period of
time, we recommend turning the 3-way switch on
the manual control panel to "Off" (manual control
panel is located on the left hand side of the fi rebox
behind the left side exterior brick panel).

Also see "Lighting Plate Instructions" for details
on how to turn off the pilot.

down the Vent. Remove any bird nests, or
other foreign material.

3) Check for evidences of excessive

condensation, such as water droplets forming
in the inner liner, and subsequently dripping
out the joints, Continuous condensation can
cause corrosion of caps, pipe, and fi ttings.
It may be caused by having excessive
lateral runs, too many elbows, and exterior
portions of the system being exposed to
cold weather.

4) Inspect joints, to verify that no pipe

sections or fi ttings have been disturbed,
and consequently loosened. Also check
mechanical supports such as Wall Straps,
or plumbers' tape for rigidity.

LOG REPLACEMENT

The unit should never be used with broken logs.
Turn off the gas valve and allow the unit to cool
before opening door and carefully remove the
