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 occasion-

ally 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.

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 aftermar-

ket* 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 at-

tached to the rear panel. This appliance is not

convertible for use with other gases.

Vermont Castings Jefferson Vent Free Gas Heater

First, determine which classification defines the in-

tended installation space.

Vent Free Features

The JUVS Gas Heater is an unvented gas appliance

Unusually Tight Construction

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.

You must provide additional fresh air if the space falls

into this classification. Unusually Tight Construction is

defined as construction wherein:

a. Walls and ceilings exposed to the outside atmo-

sphere have a continuous water vapor barrier with a

rating of one perm or less, with openings gasketed or

sealed, and

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.

b. weather stripping has been added on openable

windows and doors and

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.

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.

If your home does not meet the above criteria, follow

the procedure below.

Fresh Air Requirements for Combustion

and Ventilation

Determine If You Have a Confined or

Unconfined Space

WA R N I N G

This heater must have fresh air for proper opera-

tion. If it does not, poor fuel combustion could

result. Read the following instructions to ensure

proper fresh air supply for this and other fuel-

burning appliances in your home.

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 confined

space as a space whose volume is less than 50 cubic

feet per 1,000 BTU per hour input rating (4.8m³per Kw)

of the aggregate (total) input rating of all appliances

installed in that space and an unconfined space as a

space whose volume is not less than 50 cubic feet per

1,000 BTU per hour (4.8m³per 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.

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.

1. Determine the volume of space (length x width x

height). Include adjoining rooms connected by doorless

passageways or ventilating grilles.

Provide for Adequate Ventilation

Any space within a home can be classified in these

categories:

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)

1) Unusually tight construction

2) Confined space

3) Unconfined space

2. Divide the volume of space by 50 cubic feet. The

A. Open or provide at least two ventilating grilles to an

result is the maximum BTU/hour the space can support.

adjoining unconfined space. (Fig. 3)

Example: 3840 cubic feet divided by 50 = 76.8 or

76,800 BTU/hour.

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.)

3. Add the BTU/hour ratings of all fuel-burning appli-

ances installed in the same space, including the

following:

Gas Water Heater

Gas Fireplace Logs

Vented Gas Heater*

Gas Furnace

Vent-free Gas Heater

Other Gas Appliances*

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.

*Do not include Direct-vent appliances as these use

outdoor air for combustion and vent to the outdoors.

Example:

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.

Gas Range

4. Compare the maximum BTU/hour rating the space

can support with the total BTU/hour used by the appli-

ances.

WA R N I N G

This heater shall not be installed in a confined

space unless provisions are made for adequate

combustion and ventilation air.

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 appli-

ances. The space is considered to be Confined Space.

WA R N I N G

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.

Additional air must be provided to meet the require-

ments of the vent-free heater.

For the first fire, allow the stove to operate continuously

for six hours without using the fan. During the first fire, it

is not unusual to smell some odor associated with new

logs, paint and metal being heated. Odors should

dissipate within a few hours or so, however, you can

open a window to provide plenty of fresh air to alleviate

this condition.

Flame Characteristics

Pilot and Burner Inspection

It is important to periodically perform a visual check of

the pilot and burner flames. Compare them to the

illustration below. (Fig. 22, 23) If the flame patterns

appear abnormal contact a qualified service provider for

service and adjustment.

Each time you light your heater, check that the pilot

flame and burner flame pattern are as shown in Figures

22 and 23. If flame patterns are incorrect, turn the

heater off. See Troubleshooting, page 15.

Follow regular maintenance procedures as described

Maintenance

The following procedures will help ensure that your

stove continues to perform safely and efficiently.

Firebox Cleaning and Inspection

Screen Hooks

Cleanliness is critical to correct operation of the heater.

The log set, burner, valve controls and air circulation

areas must all be kept free of dust and unobstructed by

debris. Inspect these areas before each use and clean

whenever accumulation is evident. Follow the simple

procedure outlined below.

Frequent cleaning may be necessary in living

environments subject to excessive carpet lint or pet

hair. For example, if you live with a dog that sheds

continuously, you will need to inspect the burner area

frequently and clean it as often as the accumulation

requires. In extreme conditions, it may be necessary to

clean the burner and log set monthly or bi-weekly.

This appliance should be inspected and thor-

oughly cleaned annually by a qualified gas techni-

cian.

ST208b

Fig. 30 Remove screen.

Care of Cast Iron

Cleaning Procedure

An occasional dusting with a dry rag will help keep the

painted surfaces looking new.

1. Turn the burner OFF and let the heater cool com-

pletely before cleaning.

Porcelain enamel surfaces shoul be cleaned with a soft

damp cloth. Do not use abrasive cleaning agents. If

necessary, use only a cleaning agent formulated

specifically for use on porcelain enamel surfaces.

2. Remove the safety screen. (Fig. 30)

3. Carefully inspect the log set for damage. Contact

your local dealer if any damage is evident. DO NOT

OPERATE THE HEATER WITH A DAMAGED LOG

SET.

4. Use a soft-bristled brush vacuum attachment to

sweep dust or debris from the log set, pilot and

burner. Use care as the log set is fragile. Replace

log set according to instructions on pages 11 - 12.

WARNING

Turn the burner Pilot OFF before applying

paint. NEVER paint pilot or around pilot area.

WARNING

5. Replace the screen and Front Plate. DO NOT

OPERATE THE HEATER WITH THE SAFETY

SCREEN REMOVED.

Dust and debris accumulation can result in poor

performance. Inspect the valve compartment,

burner parts and log set frequently and clean

these parts monthly or as often as accumulation

warrants.
