AIR FOR
COMBUSTION AND
VENTILATION FOR
C100BA, CFVB200 VENT
FREE STOVE SERIES

WARNING: This heater shall
not be installed in a unusually
tight construction unless
provisions are provided for
adequate combustion and
ventilation air. Read the
following instructions to ensure
proper fresh air for this and
other fuel-burning appliances in
your home.

Today’s homes are built more energy effi­cient than ever. New materials, increased
insulation and new construction methods
help reduce heat loss in homes. Home
owners weather strip and caulk around
windows and doors to keep the cold air
out and the warm air in. During heating
months, home owners want their homes as
airtight as possible.

While it is good to make your home
energy efficient, your home needs to
breathe. Fresh air must enter your home.
All fuel-burning appliances need fresh air
for proper combustion and ventilation.

Exhaust fans, fireplaces, clothes dryers
and fuel burning appliances draw air from
the house to operate. You must provide
adequate fresh air for these appliances.

PROVIDING ADEQUATE
VENTILATION

The following are excerpts from

National Fuel Gas Code, NFPA 54/
ANSI Z223.1, Section 5.3, Air for
Combustion and Ventilation.

All spaces in homes fall into one of
the two following ventilation
classifications:

1. Unusually Tight Construction

2. Unconfined Space
The information on pages 4 through 5

will help you classify your space and
provide adequate ventilation.

Unusually Tight Construction

The air that leaks around doors and
windows may provide enough fresh
air for combustion and ventilation.
However, in buildings of unusually
tight construction, you must provide
additional fresh air.

Unusually tight construction is
defined as construction where:
a Walls and ceilings exposed to

the outside atmosphere have a
continuous water vapor re­tarder with a rating of one
perm (6 x 10
m2) or less with openings
gasketed or sealed and

b Weather stripping has been

added on openable windows
and doors and

c Caulking or sealants are

applied to areas such as joints
around window and door
frames, between sole plates and
floors, between wall-ceiling
joints, between wall panels, at
penetrations for plumbing,
electrical and gas lines and at
other openings.

If your home meets all of the two
criteria above, you must provide
additional fresh air. See Ventilation
Air From Outdoors, page 5.

If your home does not meet all of
the three criteria above, proceed to

Determining Fresh-Air Flow For
Heater Location, page 4.

kg per pa-sec-

Unusually Tight Construction or
Unconfined Space

The National Fuel Gas Code, ANSI
Z223.1 defines a unusually tight

construction as a space whose volume
is less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3per kw) of the
aggregate input rating of all appliances
installed in that space; and unconfined
space as a space whose volume is not
less than 50 cubic feet per 1,000 Btu
per hour (4.8 m3per kw) of the
aggregate input rating of all appliances
installed in that space. Rooms
communicating directly with the space
in which the appliances are installed*,
through openings not furnished with
doors, are considered a part of the
unconfined space.

This heater shall not be installed in a
unusually tight construction unless
provisions are provided for adequate
combustion and ventilation air.

*Adjoining rooms are communicating
only if there are doorless passageways
or ventilation grills between them.

Installation and repair should be done
by a qualified service person. The
appliance should be inspected before
each use and at least annually by a
professional service person. More
frequent cleaning may be required due
to excessive lint from carpeting,
bedding material, pet hair, etc. It is
imperative that control compartments,
burners a nd circu lating air
passageways of the appliance be kept
clean.

WARNING: Any change to

this heater or its controls can be
dangerous.

“WARNING: IF THE AREA IN WHICH THE HEATER MAY BE OPERATED DOES NOT MEET THE REQUIRED
VOLUME FOR INDOOR COMBUSTION AIR, COMBUSTION AND VENTILATION AIR SHALL BE PROVIDED BY
ONE OF THE METHODS DESCRIBED IN THE NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54, THE INTERNA-
TIONAL FUEL GAS CODE, OR APPLICABLE CODES.”

DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION
Determining if You Have A Unusually Tight Construction or Unconfined Space

Use this work sheet to determine if you have a unusually tight construction or unconfined space.
Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways

or ventilation grills between the rooms.

1. Determine the volume of the space (length x width x height).
Length x Width x Height = ____________________ cu. Ft. (volume of space)
Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. Ft. (volume of space)
if additional ventilation to adjoining room is supplied with grills or openings, add the volume of these
rooms to the total volume of the space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.
____________________ (volume of space) / 50 cu. Ft. = (maximum Btu/Hr the space can support)
Example: 2560 cu. Ft. (volume of space) / 50 cu. Ft. = 51,200 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.
Vent-free heater ________________ Btu/Hr
Gas water heater* ________________ Btu/Hr
Gas furnace ________________ Btu/Hr Example:
Vented gas heater ________________ Btu/Hr Gas water heater 40,000 Btu/Hr
Gas fireplace logs ________________ Btu/Hr Vent-free heater + 30,000 Btu/Hr
Other gas appliances* + ________________ Btu/Hr Total = 70,000 Btu/Hr
Total = ________________ Btu/Hr

* Do not include direct-vent gas appliances. Direct­the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
______________ Btu/Hr (maximum the space can support)
______________ Btu/Hr (actual amount of Btu/Hr used)
Example: 51,200 Btu/Hr (maximum the space can support)

70,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a unusually tight construction because the actual Btu/Hr used is more than
the maximum Btu/Hr the space can support. You must provide additional fresh air. Your options are as
follows:
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined

space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From
Inside Building, page 5.

B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 5.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined
space. You will need no additional fresh air ventilation.

“Warning: If the area in which the heater my be operated does not meet the required volume for indoor
combustion air, combustion and ventilation airs hall be provided by one of the methods described in the
National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code or applicable local
codes.”

Installation must include an equipment
shutoff valve, union and plugged 1/8"
NPT tap. Locate NPT tap within reach
for test gauge hook up. NPT tap must
be upstream from heater

(See Figure 8).

IMPORTANT: Install equipment

shutoff valve in an accessible location.
The equipment shutoff valve is for
turning on or shutting off the gas to the
appliance.

Apply pipe joint sealant lightly to male
threads. This will prevent excess
sealant from going into pipe. Excess
sealant in pipe could result in clogged
heater valves.

CAUTION: Use pipe joint

sealant that is resistant to liquid
petroleum (LP) gas.

INSTALLATION

Continued

We recommend that you install a
sediment trap in supply line. Locate
sediment trap where it is within reach
for cleaning. Install in piping system
between fuel supply and heater. Locate
sediment trap where trapped matter is
not likely to freeze. A sediment trap
traps moisture and contaminants. This
keeps them from going into heater
controls. If sediment trap is not
installed or is installed wrong, heater
may not run properly.

CAUTION: Avoid damage to

regulator. Hold gas regulator
with wrench when connecting it
to gas piping and/or fittings.

CHECKING GAS

PILOT FLAME PATTERN
(MILLIVOLT)

Figure 18 shows a correct pilot flame
pattern. Figure 19 shows an incorrect
pilot flame pattern. The incorrect pilot
flame is not heating the thermo­couple. This will cause the thermo­couple to cool. When the thermo­couple cools, the heater will shut
down.

If pilot flame pattern is incorrect, as
shown in Figure 18:

 Turn heater off (see To turn Off

Gas to Appliance, page 16)

INSPECTING

AND CLEANING

MAINTENANCE

WARNING: Turn off heater and
let cool before cleaning.

CAUTION: You must keep
control areas, burner and
circulating air passageways of
heater clean. Inspect these areas
of heater before each use. Have
heater inspected yearly by a
qualified service person. Heater
may need more frequent cleaning
due to excessive lint from
carpeting, pet hair and bedding
material, etc.

CLEANING BURNER
INJECTOR HOLDER AND
PILOT AIR INLET HOLE

The air shutter slots allow the proper
amount of air to mix with the gas. This
provides a clean burning flame. Keep
these slots clear of dust, dirt, lint and
pet hair. Clean these air inlet slots prior
to each heating season. Blocked air
slots will create soot. We recommend
that you clean the unit every three
months during operation and have
heater inspected yearly by a qualified
service person.
We also recommend that you keep the
burner tube and pilot assembly clean
and free of dust and dirt. To clean these
parts we recommend using compressed
air no greater than 30 PSI. Your local
computer store, hardware store or home
center may carry compressed air in a
can. You can use a vacuum cleaner in
the blow position. If using compressed
air in a can, please follow the
directions on can. If you don’t follow
directions on can, you could damage
the pilot assembly. NOTE: For

Townsend II See (Figure 11, page

12). For Hepplewhite See (Figure 14,
page 14). Removing access door and
top grates of your stove will make
cleaning easier.

1. Shut off unit, including pilot.
Allow unit to cool for at least thirty
minutes.

2. Inspect burner, pilot and slots in
air shutter for dust and dirt.

3. Using Phillips head driver loosen
set screw on air shutter and rotate
shutter toward rear of unit. NOTE:
Before rotating shutter mark the
position of shutter so you can

move it back to the correct position
after cleaning.

4. Opening the shutter as in step 3,
allows you to inspect the orifice.
After cleaning the area adjust air
shutter to the original position.

5. Blow air through the slots and
holes in the burner.

6. Blow air into the primary air holes
on the injector holder.

7. In case any large clumps of dust
have now been pushed into the burner
repeat steps 3 and 4.

Clean the pilot assembly also. A yel­low tip on the pilot flame indicates
dust and dirt in the pilot assembly.
There is a small pilot air inlet hole
about two inches from where the pilot
flame comes out of the pilot assembly
(See Figure 22). With the unit off,
lightly blow air through the air inlet
hole. You may blow through a drink­ing straw if compressed air is not
available.

WARRANTY INFORMATION

New Buck Corporation warrants this product to be free from defects in materials and components for two (2) year from the date
of first purchase provided that the product has been properly installed, operated and maintained in accordance with all applicable
instructions. To make a claim under this warranty the Bill of Sale or Cancelled check must be presented.

This warranty is extended only to the original retail purchaser. This warranty covers the cost of part(s) required to restore this
heater to proper operating condition and an allowance for labor when provided by a New Buck Corp. dealer. Warranty part (s)
MUST be obtained through authorized dealers of this product and / or New Buck Corp. who will provide original factory replace­ment parts. Failure to use original factory replacement parts voids this warranty. The heater MUST be installed by a qualified in­staller in accordance with all local codes and instructions furnished with the unit.

This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that fail or become
damaged as a result of misuse, accidents, lack of proper maintenance or defects caused by improper installation. Travel diagnostic
cost, labor, transportation and any and all such other costs related to repairing a defective heater will be the responsibility of the
owner.

For a period of one (1) year from the date of purchase, New Buck Corp. will replace or repair at its option: electrical motor, wiring,
switches and optional accessories.

TO THE FULL EXTENT ALLOWED BY LAW OF THE JURISDICTION THAT GOVERNS THE SALE OF THE PRODUCT:
THIS EXPRESS WARRANTY EXCLUDES ANY AND ALL OTHER EXPRESSED WARRANTIES AND LIMITS THE DU­RATION OF ANY AND ALL IMPLIED WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY AND FIT­NESS FOR A PARTICULAR PURPOSE TO TWO (2) YEARS ON ALL COMPONENTS FROM THE DATE OF PURCHASE:
AND NEW BUCK CORPORATION LIABILITY IS HEREBY LIMITED TO THE PURCHASE PRICE OF THE PRODUCT
AND NEW BUCK CORPORATION SHALL NOT BE LIABLE FOR ANY OTHER DAMAGES WHATSOEVER INCLUDING
INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES.

Some states do not allow a limitation on how long an implied warranty lasts or an exclusion or limitation of incidental or conse­quential damages, so the above limitation on implied warranties or exclusion or limitation on damages may not apply to you. This
warranty gives you specific legal rights and you may also have other rights that vary from state to state.
