Vermont Castings Jefferson Vent Free Gas Heater
General Information
Vent Free Features
The JUVS Gas Heater is an unvented gas appliance
tested and listed to the ANSI standard Z21.11.2.2000.
The Vent Free Gas Heater is configured to use Natural
Gas, (JUVSRN, JUVSMN ) or Propane (JUVSRP,
JUVSMP). Because these heaters are clean-burning
and highly energy-efficient, no venting system is
required.
The JUVS is shipped fully assembled with the
exception of the log set. The log set is assembled
during installation.
The JUVS is equipped with a Honeywell control valve
that allows thermostatic control, on/off switch or a
remote switch (not supplied).
The JUVS model incorporates variable regulators that
allow you to adjust burner heat output between HIGH,
(28,000 BTU), and LOW, (20,000 BTU). See the
Operation Section for details.
The standing pilot incorporates an Oxygen Depletion
System (ODS/pilot) which shuts off gas flow to the
burner in the event that sufficient fresh air becomes
unavailable for continued safe operation.
Unpack the Stove
Remove the stove assembly from the shipping carton
and inspect it for loose or damaged parts. Do not install
this appliance if any parts are loose or if there is any
visual or suspected damage resulting from shipping or
handling. Report damage to your dealer/distributor
immediately. The log set is packaged in the box
shipped inside the firebox.
To remove the packaged log set from the firebox:
• Lift the stove front up and then swing the bottom out
and away to disengage it from the stove body. (Fig. 3)
Cut the wire tie securing the screen.
• Remove the screen frame. (Fig. 4)
• Remove box and set aside.
Contact your dealer if the burner is loose or damaged in
any way.

Installation Requirements
Fresh Air Requirements for
Combustion and Ventilation
WARNING
This heater must have fresh air for proper operation. If it does not, poor fuel combustion could
result. Read the following instructions to ensure
proper fresh air supply for this and other fuelburning appliances in your home.
Modern construction standards have resulted in homes
that are highly energy-efficient and that allow little heat
loss. Your home needs to breathe, however, and all
fuel-burning appliances need fresh air to function
properly and safely. Exhaust fans, clothes dryers,
fireplaces and other fuel burning appliances use the air
inside the building. If the available fresh air supply is
insufficient to meet the demands of these appliances,
problems can result.
The JUVS heater has specific fresh air require-
ments. You must determine that these requirements will
be met within the space where the appliance will be
installed. The following information will help you insure
adequate fresh air is available for the heater to function
properly.
Provide for Adequate Ventilation
Any space within a home can be classified in these
categories:
1) Unusually tight construction
2) Confined space
3) Unconfined space
First, determine which classification defines the intended installation space.
Unusually Tight Construction
You must provide additional fresh air if the space falls
into this classification.
defined as construction wherein:
a. Walls and ceilings exposed to the outside atmosphere have a continuous water vapor barrier with a
rating of one perm or less, with openings gasketed or
sealed,
b. weather stripping has been added on openable
windows and doors
c. caulking or sealants are applied to areas such as
joints around windows and door frames, between sole
plates and floors, between wall and ceiling joints,
between wall panels, at penetrations for plumbing,
electrical and gas lines and at all other openings.
If your home meets all of the above criteria, you must
provide additional fresh air for the appliance as detailed
and
Unusually Tight Construction
and
is
on Page 7.
If your home does not meet the above criteria, follow
the procedure below.
Determine If You Have a Confined or
Unconfined Space
Use the following formula to determine if you have a
confined or unconfined space.
Space
is defined as the room in which you will
install the heater, plus any adjoining rooms with
doorless passageways or ventilation grilles between the
rooms.
The National Fuel Gas Code defines a
space
as a space whose volume is less than 50 cubic
feet per 1,000 BTU per hour input rating (4.8m3 per Kw)
of the aggregate (total) input rating of all appliances
installed in that space and an
space whose volume is not less than 50 cubic feet per
1,000 BTU per hour (4.8m3 per 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.
1. Determine the volume of space (length x width x
height). Include adjoining rooms connected by doorless
passageways or ventilating grilles.
Example: A room that is 18’ x 12’ x 8’ has a volume of
1728 cubic feet. An adjoining open kitchen that is 10’ x
12’ x 8’ has a volume of 960 cubic feet. An adjoining
open dining room is 12’ x 12’ x 8’ with a volume of 1152
cubic feet. The total volume is 3840 feet. (1728 + 960 +
1152)
2. Divide the volume of space by 50 cubic feet. The
result is the maximum BTU/hour the space can support.
Example: 3840 cubic feet divided by 50 = 76.8 or
76,800 BTU/hour.
3. Add the BTU/hour ratings of all fuel-burning appliances installed in the same space, including the
following:
Gas Water Heater Gas Furnace
Gas Fireplace Logs Vent-free Gas Heater
Vented Gas Heater* Other Gas Appliances*
*Do not include Direct-vent appliances as these use
outdoor air for combustion and vent to the outdoors.
Example:
Gas Range 55,000 BTU/hour
Vent-free Logset +25,000 BTU/hour
Total 80,000 BTU/hour
unconfined space
confined
as a
66
Vermont Castings Jefferson Vent Free Gas Heater
4. Compare the maximum BTU/hour rating the space
can support with the total BTU/hour used by the appliances.
Example:
76,800 BTU/hour the space can support
80,000 BTU/hour used by appliances
In this example, the maximum BTU/hour that the space
can support is less than the total used by the appliances. The space is considered to be
Confined Space.
Additional air must be provided to meet the requirements of the vent-free heater.
A confined space may be ventilated in two ways:
A. Open or provide at least two ventilating grilles to an
adjoining unconfined space. (Fig. 2)
Each of the two grilles must provide an opening of at
least 50 square inches, with all opening dimensions
being at least 3”. One grille must be within 12” of the
ceiling; the other within 12” of the floor. (If the total
exceeds 100,000 BTU/hour, additional grilles will be
needed.)
B. Vent the room directly to the outdoors. (Provide one
square inch of opening for each 4,000 BTU/hour)
For further information on ventilation guidelines and
sizing specifications, follow the National Fuel Gas
Code/NFPA 54/ANSI Z223.1, Section 5.3.
If the total BTU/hour used by the appliances is less
than the maximum BTU/hr the space can support, the
room meets the
Unconfined Space
criteria and no
further ventilation is needed.
WARNING
This heater shall not be installed in a confined
space unless provisions are made for adequate
combustion and ventilation air.
WARNING
If the area in which the heater may be operated is
smaller than that defined as an unconfined space,
provide adequate combustion and ventilation air by
one of the methods described in the National Fuel
Gas Code, ANSI Z223.1, 1992 Section 5.3.
