Gas Supply Pressures
This appliance must be isolated from the gas supply
piping system by closing its individual manual shut off
valve during any pressure equal to or less than 1/2 psig
(3.45 kPa).
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).

Mounting the Appliance
The appliance should only be mounted on the following
surfaces:
• A flat combustible (burnable) surface.
• A raised wooden platform.
• A concrete block or other solid object placed be-
neath each of the four corners of the appliance.
To mount the appliance:
1. Choose unit location.
2. Two different styles of nailing flanges are supplied
with the fireplace (found on the fireplace hearth).
(Fig. 3) To level the box and secure it firmly in place,
remove the nailing flanges form the hearth and install
at the sides of the fireplace as shown in Figure 4.

Insulating for Cold Climates
When an appliance is installed in a chase or an outside
wall, the enclosure should be insulated like any other
wall of the home. Insulation should be installed under
the appliance and on the inside of the exterior walls.
In a chase, it is a good idea to install a firestop at the
first ceiling level above the appliance. Also, install insu-
lation on the side walls. Insulation may then be placed
above the ceiling to assure the space around the appli-
ance is protected. (Fig. 2)
Be sure to always maintain the proper one (1) inch
distance to combustibles around the B-vent pipe
sections.
NOTE: Insulating for cold climates is strictly a recom-
mendation, not a requirement.

Installation
Framing
Framing can take place before or after the appliance
is set in place. The framing should be positioned to
accommodate the wall covering and facing material.
Framing material should be 2x4 or heavier. Framing
headers may rest on top of standoff. (Page 3, Fig. 1)
Gas Line Installation
If gas piping from the source to the appliance 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 right
side of the appliance.* A knockout is provided to allow
for the gas pipe installation and testing of any gas con-
nection.
* For the NVCR36L and the left side on the NVCR36R.
NOTE: The gas line connection can be made with
properly tinned 3/8” copper tubing, 1/2” rigid pipe or an
approved flex connector, then reduced to 3/8” to the
appliance. Because some municipalities have some
additional local codes, it is always best to consult your
local authority.
U.S.: Consult the current National Fuel Gas Code, ANSI
Z223.1/NFPA 54.
CANADA: CSA B149.1 installation code.
Always check for gas leaks with a mild soap
and water solution. Use a 50/50 solution of
liquid soap and water to test for leaks at gas
fittings and joints. Apply water/soap solution
with a brush only - do not over apply.
NEVER! test with an open flame.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to pro-
vide a 1/8” test point up stream of the control.
When using copper or flex connector, use only ap-
proved fittings. Always provide a union so that gas line
can be easily disconnected for burner or fan servicing.
See gas specification for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the appliance. (Fig. 5)
Option for E Models ONLY -
EB1 (Receptacle) Hook-Up
Wiring should be installed by a certified
electrician.
Turn off circuit breaker before wiring
models.
Once the fireplace is secured, complete wiring the fan
kit. Remove knockout in the center of the back of the
EB1 and install listed cable clamps. Feed electrical
wire through cable clamp leaving approximately six
(6) inches of wire exposed through EB1. Secure cable
clamp to the wire.
Attach white wire from power source to one
(1) wire of receptacle and secure with a nut.
Attach black wire from power source to the
other wire of the receptacle and secure with a
nut. Be sure nuts are tightened securely
Secure the EB1 assembly to the inside of the electrical
box coverplate using two (2) screws. Attach the cover
to the face of the EB1 while being careful to position ex-
cess wire completely within EB1. Attach the coverplate
to the fireplace. (Fig. 6)
U.S. Installations: Follow local codes and the National
Electrical Code, ANSI/NFPA NO. 700.
Canadian Installations: Follow local codes and the
current CSA C22.1 Canadian Electrical Code.

amount of air will be trapped in the line. When first
lighting the unit with pilot light, it will take a few minutes
to purge the trapped air. Once purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the appli-
ance will not require purging.
When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubri-
cants used in the manufacturing process. After each
lighting, vapor may condense and fog the glass; this
moisture disappears in a few minutes of burning.

Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 18)
To adjust pilot burner, turn pilot screw marked “pilot” for
proper flame size.
The air shutter is set at the factory, therefore there is no
adjustment necessary.

Cleaning Automatic Direct
Electronic Ignition System
The Electronic Ignition burner/control system consists
of:
• main burner
• gas orifice
• hot surface pilot burner
• 24VAC valve with transformer
Taking care of the Electronic Ignition units is almost
identical to taking care of the Standing Pilot models.
(See Maintenance sections on page 16.) The hot sur-
face ignitor is the only component which requires EX-
TREMELY DELICATE HANDLING. The ignitor is made
of silicone carbide which is a very brittle material. DO
NOT TOUCH THE HEATING PART OF THE IGNITOR
WITH YOUR FINGERS!

Flame Adjustment
For units equipped with Hi/Lo valves flame adjustment
is accomplished by rotating the Hi/Lo adjustment knob
located near the center of the gas control.
It is important to periodically perform a
visual check of the pilot and the burner
flames. (Figs. 18 and 20)

Maintenance
Keep the control compartment, logs and burner area
surrounding the logs clean by vacuuming or brushing
at least twice a year. THE LOGS CAN GET VERY HOT
- HANDLE ONLY WHEN COOL.
Always turn off gas to the pilot before cleaning. For re-
lighting, refer to lighting instructions located on the front
cover plate.
Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obstacles
and materials.
Leave at least 36” clearance from front of appliance to
combustibles.
Cleaning Glass Doors
Only glass approved for use in the Vermont Castings,
Majestic Products Company products may be used for
replacement.
1. The use of substitute glass will void all product war-
ranties.
2. Care must be taken to avoid breakage of the glass.
3. Under no circumstances should this appliance
be operated with a broken glass front.
Replacement of the glass as supplied by
the manufacturer should be done by a
licensed qualified service person.
It will be necessary to clean the glass periodically. Dur-
ing start-up, condensation (which is normal) forms on
the inside of the glass and causes lint, dust and other
airborne particles to 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 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 opera-
tion.
Inspecting the Venting System
The appliance venting system was designed and con-
structed to develop a positive flow adequate to remove
flue gasses to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gasses (i.e.: carbon monoxide) into the
room.
To inspect the venting system, make sure the main gas
valve is off. Remove the glass panel. Using a flashlight,
check the combustion dome. Clean if necessary.
Cleaning the Standing Pilot
Control System
The burner and control system consists of:
• main burner
• gas orifice
• pilot burner
• thermopile
• combination millivolt gas valve
Most of these components may require only an occa-
sional checkup and cleaning and some may require ad-
justment. 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, open glass door (if used),
remove 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. Visu-
ally 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 the pilot and
burner’s flame characteristics are steady, not lifting or
floating.
