WARNING: Check with your electronics manufacturer
before installing a television or other electronic device above this fireplace.
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during the start up or
cool down cycle. Similar noises are found with your furnace
heat exchanger or car engine.
It is not unusual for your gas fireplace to give off some odor
the first time it is burned. This is due to the curing of the paint
and any undetected oil from the manufacturing process.
Please ensure that your room is well ventilated - open
all windows.
It is recommended that you burn your fireplace for at least ten
(10) hours the first time you use it. If optional fan kit has been
installed, place fan in the "OFF" position during this time.

Framing & Finishing
For Zero Clearance Kit applications, it is important to
determine the finished facing material before beginning
to frame. This will allow for the thickness of the finishing
material between the frame and the fireplace trim.
Similarly, consideration must be given to the 1" inch
depth of the air inlet channel sitting on the fireplace
base. Finishing material for the hearth should be flush
with the top of the air inlet channel.
If the fireplace is installed at floor level a noncombustible hearth must extend a minimum 12" (305 mm) in
front of the fireplace.
If the fireplace is recessed into the wall and at least 12"
(305 mm) above floor level, no hearth is required.
The use of wallpaper adjacent to this fireplace is not recommended as high temperatures given off by this fireplace may
adversely effect the binders in the adhesive used to apply the wallpaper.

NOTE: Insulating around the fireplace will result in
overheating and possible malfunctioning of the circulating fan.
Zero Clearance Applications
An alternate air supply is recommended
with this component.
For installation other than in existing woodburning fireplaces such as new construction or renovation projects, a Zero Clearance Kit must be used. The
kit enables these inserts to be installed in combustible
environments. Whenever using a Zero Clearance Kit,
consideration must be given to the dimensions of the
Zero Clearance Kit and the requirements of the Air Kit.
NOTE: If a Zero Clearance Kit is required for models LHECDV20/LHERDV20/LHECDV30/LHERDV30
Direct Vent Inserts, only the CFM Corporation zero
clearance kit HEZC combined with the HEDVCAK is
approved to be used. Refer to Page 9, figure 10 for
HEDVCAK chimney adapter kit installation. When
using the HEZC with insert models LHECDV20 or
LHERDV20, the Trim Closure Kit, LHE20TCK, must
also be installed.

Preparation
Before beginning, remove glass door and logs from
unit. Also check to make sure there is no hidden
damage to the unit. Take a minute and plan out the
gas,venting and electrical route. It is best to start with
the gas line first followed by the chimney liner. (Refer to
Page 9)
Gas Line Installation
When purging the gas line, the front glass
must be removed.
If gas piping from the source to the heater
location has not been accomplished, install the required
pipe. Consult local plumbing code to assure proper pipe
size.
The gas pipeline can be brought in through the rear or
the base of the heater.
NOTE: The gas line connection can be made of either
properly tinned 3/8" copper tubing, 1/2" rigid pipe or
an approved flex connector then reduced to 3/8" to the
heater. Some municipalities have additional local codes,
it is always best to consult your local authority and the
CSA- B149.1 installation code.
U.S. Installations consult the current National Fuel
Gas Code, ANSI Z223.1/NFPA 54.
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
The gas control is equipped with a captured screw
type pressure test point, therefore it is not necessary to
provide a 1/8" test point up stream of the control.
When using copper or flex connector, use only
approved fittings.
using black iron pipe so the gas line can be easily
disconnected for burner or fan servicing. See gas
specifications for pressure details and ratings. NOTE:
If flex connector is used, it must be kept inside of the
heater.
Always provide a union when

Installer must attach red warning plate
with screws supplied with the gas fireplace
insert to the inside of the firebox of the
fireplace into which the gas fireplace insert
is installed.
Cutting any sheet metal parts of the fireplace, in which the gas fireplace insert is
to be installed, is prohibited.
If the factory-built fireplace has no gas
access hole(s) provided, an access hole of
1¹⁄₂� (38 mm) or less may be drilled through
the lower sides or bottom of the firebox in
a proper workmanship-like manner. This
access hole must be plugged with a noncombustible insulation after the gas supply line has been installed.

Liner Installation
The collar extending down from the termination base
is the air intake connector. Be sure the flex vent, which
is connected to this collar, is also connected to the
labelled air intake flue collar on the fireplace. Make sure
the flex vent is attached on the correct collar and cap
for exhaust as well.
Slide the insulation provided in the termination kit over
the two (2) 3" flex liners, (to be attached to the 3" flue
collar and cap of the termination). Feed one 3" flex
vent from the bottom of the termination up through the
4" sleeve. Apply hi-temp sealant on the rain cap collar and slide the flex vent over the end of the rain cap
collar fastening with the clamp provided. Slide the flex
liner back down the 4" sleeve until 4" cap slides over
the sleeve. Attach cap to the sleeve with four (4) screws
supplied. Apply hi-temp sealant over the air intake
collar and attach intake flex vent in the same method.
Feed the two flex liners down the chimney through the
damper opening. Tighten termination to the chimney
using the screws provided. (Fig. 10) NOTE: For Round
Vent Terminations - tighten termination to the chimney
by pushing the four (4) straps of the vent termination
against the chimney and secure with four (4) screws
provided. (Fig. 12)
In case the fireplace opening is only minimum height
21" (533 mm) and access from the front is not possible,
follow the instructions below.
1. Remove flue collar plate assembly. Unbolt the top
fastener plate and move it to the back first before
sliding the flue collar plate out from the top of the
unit. (Fig. 13)
2. Apply a bead of hi-temp sealant on the end of the
collar before attaching the liner to the flue collar.
Fasten it with two clamps then adjust fastener plate
all the way to the back before sliding flue gas plate
back onto the unit. (Figs. 14 and 15)
3. After the flue collar plate is set on the cabinet top,
make sure the front edge of the flue collar plate is
completely in contact with the back edge of the cabinet top. (Fig. 16)
4. Put the machine screw back into the fastener plate.
Bolt the plate until it is locked. (Fig. 17)
Under no circumstances should insulation
be put between the damper and the top of
the unit. This may cause condensation and
overheating of the unit.
