Clearance Requirements
Minimum Clearances to
Combustible Materials
Maintain clearance, (empty space), between combustible materials and the heater as specified below for
the appropriate firebox shell being installed.
The JUVS must be installed on rigid flooring. If the
appliance is installed on any combustible surface other
than wood flooring, such as carpet or tile, a metal or
wood panel must be installed to extend the full length
and width of the unit.
WARNING
• Do not install this heater in a bathroom or
bedroom.
C
• Installation of this heater must conform with
Local Codes or in the absence of Local
Codes, with the National Fuel Gas Code,
ANSI Z223.1.
• This heater creates warm air currents. These
currents move heat to wall surfaces next to
the heater. Installing the heater next to vinyl
or cloth wall coverings or operating the
heater where impurities in the air such as
tobacco smoke exist, may discolor walls.
• Do not use a blower insert, heat exchanger
insert or other accessory not approved with
this heater.
The installation of your Vermont Castings stove must
conform with local codes, or in the absence of local
codes, with the National Fuel Gas Code ANSI
Z223.1 - latest edition. (EXCEPTION: Do not derate
this appliance for altitude up to 4,500 feet (1,370m).
Maintain the manifold pressure at 3.5” w.c. for
Natural Gas and 11.0” w.c. for LP Gas.
This appliance may be installed in an aftermarket* manufactured (mobile) home, where not
prohibited by state or local codes.
This appliance is to be used only with the type of
gas specified on the rating plate which is attached to the rear panel. This appliance is not
convertible for use with other gases.
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration from elevations up to
4,500 feet (1,370m) above sea level.
Nuisance outages may occur at altitudes above
4,500 feet (1,370m) if dirt, dust, lint and/or cobwebs are allowed to accumulate on burner and/or
ODS pilot. Monthly inspection and cleaning is
recommended for altitudes above 4,500 feet
(1,370m)
For elevations above 4,500 feet (1,370m), installations must be in accordance with the current
ANSI Z223.1 and/or local codes having jurisdiction.
WARNING: Improper installation, adjustment, alteration, service or maintenance can
cause injury or property damage. Refer to
this manual for correct installation and
operational procedures. For assistance or
additional information consult a qualified
installer, service agency, or the gas supplier.
Odor During Operation
Neither natural gas nor propane gas give off an odor
when burned. The nature of a vent free combustion
system, however, is such that odors may occasionally be produced during heater operation when
impurities exist in the immediate area. Cleaning
solutions, paint, solvents, cigarette smoke, candles,
adhesives, new carpet or textiles, etc., all can create
fumes. These fumes may mix with combustion air
and can create odor. Such odors will disappear over
time, however the condition can be alleviated by
opening a window or otherwise providing additional
ventilation to the area.
*Aftermarket: Completion of sale, not for purpose of resale, from
the manufacturer.

Vent Free Features
The JUVS Gas Heater is an unvented gas appliance
tested and listed to the ANSI standard Z21.11.2a.2001.
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.
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 requirements. 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
on Page 7.
If your home does not meet the above criteria, follow
the procedure below.
and
Unusually Tight Construction
and
is
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)
