Appliance Clearances to Combustible Materials
We strongly recommend that you DO NOT install
B-Vent Gas Appliances in strong negative air
locations, such as a basement or a public facility.
Living rooms with cathedral ceilings could be
susceptible to a negative air situation, but such
installations can be overcome through raising
the termination, depending on specific
installations. This appliance uses room air for
normal operation and could have problems
establishing a positive draft in a negative air
location. In lieu, we recommend a direct vent
appliance.

clearances for servicing and proper operation.
D. SETTING THE APPLIANCE
1. POSITIONING THE APPLIANCE
This appliance may be placed on a smooth
combustible or noncombustible, continuous flat
surface. When the appliance is installed directly on
carpeting, tile or other combustible material other than
wood flooring, the appliance shall be installed on a
metal or wood panel extending the full width and depth
of the appliance. Slide the appliance into position and
level from side-to-side and front-to-back. Shim with
noncombustible materials as necessary.
E. VENTING
1. VENT HEIGHT
This appliance requires a 5 B-vent for operation.
Never downsize pipe. It must be terminated above
the roof line. ollow all B-vent requirements and
installation instructions, including minimum
clearances.
The minimum height of vent installation must be nine
feet from the top or twelve feet from the base of the
appliance. Horizontal run must never exceed 50% of
the height of the vent system as shown in igure 4.
Secure the appliance by bending out the nailing
flanges on each side of the appliance and nail to
framing. The nailing flanges have been positioned
5/8 inch back from the front of the appliance to allow
the addition of drywall.
2. ATTACHING VENTING
a. Assembling Vent Sections. Attach straight vent
section to the top of appliance. Use only B-vent
sections.
b. Attaching the Vent to the Collar Shield. Three
tabs extend from the collar shield to the B-vent
section. Screw the tabs to the B-vent section using
self-tapping screws.
c. Using Elbows. Elbows exceeding 45° from the
vertical shall be considered horizontal and
therefore adapt horizontal run limitations. See
igure 5.
igure 4
Venting Off the Top of Appliance
Note: Vertical rise off the top of the firebox before elbow-
ing creates a less restrictive venting environment. igure 5 - Using Elbows
WARNIN !
To prevent contact with sagging or loose
insulation, the appliance must not be installed
against vapor barriers or exposed insulation.
Localized overheating could occur and a fire

01-02 7 28466 Rev H
NOVUS B-VENT INSTALLATION INSTRUCTIONS
3. FIRESTOP SPACER/VENT
INSTALLATION
rame an opening and install a firestop spacer
whenever the vent penetrates a ceiling floor area, as
shown in igure 6. rame the opening with the same
sized lumber as used in the ceiling/floor joist. Unless
the flue is offset, the hole should be directly above the
appliance. DO NOT pack insulation around the vent.
Assemble vent sections with three screws per joint.
WARNIN - RISK OF FIRE
Always maintain minimum clearances or greater
around the vent system. Do not pack air spaces with
insulation or other material. The flow of combustion
and ventilation air must not be obstructed.
WARNIN !
The horizontal run of vent must have a 1/4 rise for
every 1 ft. of run towards the termination. Never allow
the vent to run downward. This could cause high
temperatures and may present a fire hazard.
WARNIN !
When vent sections exceeding three feet in length
are installed between an offset/return, structural
support must be provided to reduce off-center
loading and prevent vent sections from separating
at the vent joints. ollow all B-vent manufacturer
guidelines.
4. CHASE/TERMINATION INSTALLATION
igure 7 and Table 1 specify minimum vent heights
for various pitched roofs. Vent sections may have to
be cut to a certain length.
These vent heights are necessary for safety and do
not ensure draft-free operation. Trees, buildings,
adjoining roof lines, adverse conditions, etc., may
create a need for a taller vent should down drafting
occur.

5. CHECK VENTING SYSTEM
Check the venting system to assure proper operation.
This can be done with a match while the appliance is
operating.
Hold a lighted match at the bottom edge of the draft
hood opening. If the flames and smoke remain upright,
ventilation is acceptable. If the flames and smoke are
drawn into the draft hood, this means ventilation is
good. If the flames and smoke are forced away from
the draft hood, this may indicate a ventilation blockage
or down draft resulting in gas spillage into the home.
If this occurs, turn off the appliance and do not burn it
until it has been inspected by a qualified service
person. See igure8.
Table 1
Vent Height
6. INSTALLING AN OUTSIDE AIR KIT
(STRONGLY RECOMMENDED)
An AK14 Outside Air Kit should be purchased as a
feature with this appliance. An outside air kit helps to
decrease the amount of room air taken by utilizing
outside air for combustion. igure 9 illustrates two of
many possible methods that can be used to supply
outside air to the appliance.
A maximum of 40 of air kit ducting is allowed. The air
kit must terminate at least three feet below the venting
termination and must terminate to the outside.
igure 8
Testing Ventilation
WARNIN !
Exhaust products of gasoline engines are
hazardous. The outside air must not be taken from a
garage space, attic spaces, basements or above
the roofing where other heating appliances, fans or
