9. Under no circumstances should any solid fuels (wood,
coal, paper or cardboard etc.) be used in this appli­ance.

10.The flow of combustion and ventilation air must not be
obstructed in any way.

11.Whether the appliance is installed directly on carpet­ing, vinyl tile or any combustible material other than
wood, this appliance must be installed on a metal or
wood panel extending the full width and depth of the
appliance.

12. This appliance requires adequate ventilation and
combustion air to operate properly.

Description

NVB Series are radiant or heat circulating, natural draft
appliances and use a 6" B-vent system. Do not burn
wood or other materials in these appliances. Each model
is available with standing pilot or electronic ignition for
use with Natural or Propane gas units.

Report to your dealer any parts damaged in shipment.
Adequate combustion and ventilation air must be pro-

vided. The flow of combustion and ventilation air MUST
NOT be obstructed.

Provide adequate clearances around the air opening into
the combustion chamber; and adequate accessibility
clearance for servicing and proper operation. NEVER
obstruct the front opening of the appliance or cover the
top and bottom louvres (grilles).

The 6" vent system MUST connect to the appliance and
terminate out-of-doors in a vertical position and terminate
with a B-vent cap.

This appliance must not be connected to a chimney flue
servicing a separate solid-fuel burning appliance.

A draft hood is an integral part of the appliance.

Proposition 65 Warning: Fuels used in gas,
woodburning or oil fired appliances, and the products
of combustion of such fuels, contain chemicals known
to the State of California to cause cancer, birth defects
and other reproductive harm.
California Health & Safety Code Sec. 25249.6

IMPORTANT:

PLEASE READ THE FOLLOWING CAREFULLY

Remove any plastic from trim parts before turning the
fireplace “ON”.

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 Vermont Castings, Majestic
Products 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 used in 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) continuous hours the first time you use it.
If the optional fan kit has been installed, place the fan
switch in the “OFF” position during this time.

Mantels\

The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.

For the correct mounting height and widths refer to
Figures 5a and 5b

The distances and reference points are not affected by
the fitting of a bay window front trim kit.

Noncombustible mantels and legs may be installed at
any height and width around the appliance.

When using paint or lacquer to finish the
mantel, such paint or lacquer must be
heat resistant to prevent discoloration.

A hearth is not mandatory but is recommended for
aesthetic purposes. We recommend a noncombustible
hearth.

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
insulation on the side walls. Insulation may then be
placed above the ceiling to assure the space around the
appliance is protected. Refer to Page 8, Figure 7.

7412950

Majestic Fireplaces® NVB Series B-Vent

Be sure to always maintain the proper
one (1) inch distance to combustibles
around B-vent pipe sections.

NOTE: Insulating for cold climates is strictly a recom-

mendation and not a requirement.

Framing and Finishing

Check appliance to make sure it is
levelled and properly positioned.

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 beneath each of the four corners

of the appliance.

To mount the appliance:

1. Choose unit location.

2. Four (4) nailing flanges are supplied with the fire­place (found on the fireplace hearth). To level the box
and secure it firmly in place, remove the nailing
flanges from the hearth and install at the sides of the
fireplace as shown in Figure 6.

Finishing

CAUTION: All joints between the finished

the appliance surround (the black painted
face).

When finishing the appliance, never obstruct or modify
the air inlet/outlet grilles in any manner.

Finish the wall with the material of your choice. Refer to
Figures 5a and 5b for specific clearances when install­ing a combustible mantel or other combustible projec­tion.

Gas Line Installation

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).

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.

8

FP597

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
connection. It is most convenient to bring the gas line
in from the right side, as this allows fan installation or
removal without disconnecting the gas line.

NOTE: The gas line connection can be made with 3/8"
copper tubing approved for propane or natural gas, 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.
