Mantels
Vermont Castings, Majestic Products LHE Natural Vent Insert
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.

Zero Clearance Applications
An alternate air supply is recommended
with this component.
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" (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.
10005360
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 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.

High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1 and/or local codes having
jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
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.

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,
remove the flue collar plate - unscrew and slide out from
the back of the unit. Now attach the liner to the flue
collar, lift up and slide flue collar plate back onto the unit
top. It is important that the plate is completely inserted
and the front screw is fastened again in order to line up
the flue outlet and the liner properly. (Fig. 11)
Test Chimney Draw
1. A "Chimney Draw" test must be conducted before
the installation is complete.
2. Close all doors and windows in the home and start
exhaust fans in he kitchen and bathroom.
3. Light unit and operate for 5 minutes.
4. Hold an ignited match or cigarette in front of the unit.
Refer to drawing for the location of the draft hood
opening. (Fig. 12)
5. Check to make sure smoke from the match or
cigarette is drawn into the fireplace. If it is not, turn
the unit off and check for causes creating the lack of
adequate draft.
Test for draft at these two
openings.

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 themselves 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 disappears within a few minutes of burning.

Maintenance
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Fan Assembly
The fan unit requires periodic cleaning. At least once
per month in the operating season, open the lower
louvre panels and wipe or vacuum the area around the
fan to remove any build up of dust or lint.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner • pilot burner
• gas orifice • thermopile
• combination millivolt gas valve
Most of these components may require only an occasional checkup and cleaning and some may require
adjustment. If repair is necessary, it should be performed by a qualified technician.
In order to properly clean the burner and pilot assembly,
turn off the gas to the unit, remove the window frame
panel and logs exposing the burner and pilot assembly.
Clean all foreign materials from the top of the burner.
Check to make sure that burner parts are clean.
Visually inspect pilot. Brush or blow away any dust or
lint accumulation. If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
