When the unit is installed into a woodburning fireplace,
the minimum distance the mantel can be placed above
the fireplace is governed by local building codes
applicable to woodburning fireplaces. Consult local
authorities having jurisdiction for these clearances.
For applications requiring the use of a Zero Clearance
Kit, the minimum height a mantel can be installed
above the fireplace is 24" (610mm) from the top of the
upper louvres. The maximum mantel depth is 8"
(200mm). (Fig. 2)
The underside of the mantel will become
warm. Use only finishes which are heat
resistant and do not discolor.
Mantels

Fig. 2 Minimum mantel height above fireplace.
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 noncombus-
tible hearth must extend a minimum 12" (305mm) in
front of the fireplace.
If the fireplace is recessed into the wall and at least 12"
(305mm) 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 circulat-
ing 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 mod-
els LHEC20/LHER20/LHEC30 Natural Vent Inserts,
only the Vermont Castings, Majestic Products zero
clearance kit HEZC is approved to be used. When
using the HEZC with insert models LHEC20 or
LHER20, 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
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. Always provide a union when 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.

place 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 1.5 inch (37.5mm) 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 insula-
tion after the gas supply line has been
installed.
Venting Installation
1. The fireplace may be installed in and vented through
any solid fuel fireplace that has a minimum fireplace
opening 25¹⁄₄"W x 17¹⁄₂" H x 13¹⁄₂"D for LHEC20 and
LHER20 or 28³⁄₄"W x 21"H x 15¹⁄₂"D for LHEC30 and
has been installed in accordance with the National,
Provincial/State and local building codes and is
constructed of noncombustible materials.
2. In order to gain minimum gas insert fireplace
opening requirement, if the fire brick refractory is
removed from a factory built fireplace, a minimum of
1/4" air space is required between the gas insert
fireplace's outer casing and the inner wall of the
factory built fireplace.
3. In order to obtain the best performance, safety and
efficiency for the gas insert fireplace, the LHEC30
gas insert must be installed with an approved 4"
diameter flue liner. The LHER20 and LHEC20
should be installed with an approved 3" diameter flue
liner as per current CSA-B149.1 or National Fuel
Gas Code ANSI Z223.1.
4. Any flue damper must be removed or blocked open.
5. The chimney must be clean and in good working
order and constructed of noncombustible materials.
6. Make sure that all chimney cleanouts fit properly so
air cannot leak into the chimney.
7. Install the appliance without trim frame and make all
gas fittings and electrical connections.
8. Install the decorative trim frame. Please refer to the
Frame Assembly instructions.
CAUTION: Do not wire millivolt remote
wall switch for gas fireplace to a 120v

A minimum 12' (3.7m) vent height is
required to effectively vent these fire-
places.
Common Flue Installations
In some areas it is possible to vent more than one gas
appliance into the same flue. You must ensure that the
flue being shared has the proper capacity to handle
both appliances. Check installation codes for venting
capacity information.
As always it is best to check with the authority having
jurisdiction prior to commencement of the installation.
Liner Installation
Insert liner from top of chimney through the damper
opening and attach to 3" flue collar for LHEC20 and
LHER20 and 4" flue collar for LHEC30. For best results
use three (3) sheet metal screws and a hose clamp.
For natural draft inserts, packing noncombustible
fiberglass insulation around the liner in the damper area
will isolate the fireplace cavity from the chimney and
prevent drafts and noises during operation.
In case the fireplace opening is only minimum height
(17¹⁄₄" (438mm) for LHEC20 and LHER20; 21" (533mm)
for LHEC30) and access from the front is not possible,

Glass Cleaning
It will be necessary to clean the glass periodically.
During start-up condensation, which is normal, forms
on the inside of the glass and causes lint, dust and
other airborne particles cling to the glass surface. Also
initial paint curing may deposit a slight film on the
glass. It is therefore recommended that the glass be
cleaned two or three times with a non-ammonia
household cleaner and warm water (we recommend
gas fireplace glass cleaner). After that the glass should
be cleaned two or three times during each heating
season depending on the circumstances present.
Clean glass after first two weeks of
operation.

First Firing
Upon completing the gas line connection, a small
amount of air will be in the lines. When first lighting unit
with pilot light, it will take a few minutes to purge them-
selves of this air. Once the purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the heater
will not require such purging.
When lit for the first time, the appliance will emit a slight
odor for awhile. This is due to paint and lubricants used
in the manufacturing process. After each lighting, vapor
may condense and fog the glass; this moisture disap-
pears within a few minutes of burning.
