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.

Provide For Adequate Ventilation
Any space within a home can be classified in the
following categories:
1) Unusually Tight Construction
2) Confined Space
3) Unconfined Space
First, determine which classification defines the
intended space.
Unusually Tight Construction
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
atmosphere have a continuous water vapor retarder
with a rating of one perm 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 three criteria above, you
must provide supplemental fresh air for the appliance
from outside the home as detailed on page 7, B.
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 confined space
as a space whose volume is less than 50 cubic feet per
1,000 BTU per hour, (4.8 m3 per kw), of the aggregate
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, (4.8
m3 per kw), of the aggregate input rating of all appli-
ances 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.
Vent Free Features
The UVS27, Model Nos. 3030 thru 3033, is an
unvented gas heating appliance tested and listed to
the ANSI standard Z21.11.2a-2001. This appliance is
specifically configured to burn either Natural Gas or
Propane fuel, as indicated on the metal rating plate
attached to the rear shroud. The UVS27 is not fuel
convertible.
The firebox is shipped fully assembled and ready for
installation with either the Stardance (SUV) or the
Pinnacle (PUV) shell assemblies.
The firebox assembly is composed of the NG or LP
Burner, a base plalte, firebox and screen. The log set,
burner tube, gas valve and pilot comprise the Burner
assembly. (Fig. 1)
The UVS27M is equipped with an SIT control for
manual use only.
The UVS27R is equipped with a Honeywell control
valve that allows thermostatic control, on/off switch or a
remote switch (not supplied).
Both models incorporate variable regulators that allow
you to adjust burner heat output between HIGH,
(28,000 BTU), and LOW, (19,500 BTU). See the
Operation Section for details.
The standing pilot incorporates an Oxygen Depletion
System (ODS/pilot) designed to shut off the appliance if
enough fresh air is not available.
Thisheatermusthavefreshairforproperoperation.
Ifnot, poor fuel combustion could result. Read the
followinginstructionstoinsureproperfreshairfor
this and other fuel-burning appliances in your
home.
Fresh Air Requirements for Combustion
and Ventilation
WARNING
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 within it require fresh air in
order to function properly and safely. Exhaust fans,
clothes dryers, fireplaces, and other fuel burning
appliances all use the air inside the building. If the
available fresh air is insufficient to meet the demands
of these appliances, problems can result.
The UVS27R/M Unvented heater has specific fresh air
requirements. You must determine that these fresh
air requirements will be met within the space where
the appliance will be installed. The following informa-
tion will help you insure that adequate fresh air is
available for the heater to function properly.

8
Vermont Castings UVS27 Vent-Free Gas Heater
20005004
Example:
A room that is 18' x 12' x 8' has a volume of 1728
cubic feet, ( length x width x height). 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 space
volume is 3840 cubic feet. (1728 + 960 + 1152).
2. Divide the volume of space by 50 cubic feet. The
result is the maximum BTU/Hr that the space can
support.
Example:
3840 divided by 50 = 76.8 or 76,800 BTU/Hr.
3. Add the BTU/Hr ratings of all fuel-burning appli-
ances installed in the same space, including the
following:
Gas Water Heater Gas Furnace
Gas Fireplace Logs Unvented Gas Heater
Vented Gas Heater* Other Gas Appliances*
* Do not include Direct Vent appliances as these
utilize outside air for combustion and vent to the
outdoors.
Example:
Gas Range 55,000 BTU/Hr
Unvented Heater +33,000 BTU/Hr
Total 88,000 BTU/Hr
4. Compare the maximum BTU/Hr rating the space can
support with the total BTU/Hr used by the appliances.
Example:
76,800 BTU/Hr - max. the space can support
88,000 BTU/Hr - total used by appliances
In this example, the maximum BTU/Hr that the space
can support is less than the total used by the appli-
ances, the space is considered to be Confined space .
Additional air must be provided to meet the require-
ments of the Unvented heater.
WARNING
This heater shall not be installed in a confined
space or unusually tight construction 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
spaceof if the building is of unusually tight
constructins, provide adequate combustion and
ventilation air by one of the methods described
in the National Fuel Gas Code, ANSI Z223.1,
NFPA 54, Section 5.3 or applicable codes.
A confined space may be ventilated in two ways:
A) Open up or provide at least two ventilating grilles
to an adjoining unconfined space. Use any of the
options illustrated in Figure 8.
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 located within 12"
of the ceiling; the other within 12" of the floor. (If the
total exceeds 100,000 BTU/Hr, additional grilles will be
required.)
B) Vent the room directly to the outdoors. (Provide
one square inch of opening for each 4,000 BTU/hr.
If the total BTU/Hr used by the appliances is less than
the maximum BTU/Hr the space is able to support, the
room meets the Unconfined space
criteria and no
further ventilation is required.
For further information on ventilation guidelines and
sizing specifications follow the National Fuel Gas Code
NFPA 54/ANSI Z223.1 Section 5.3.

The following procedures will help ensure that your
heater continues to perform safely and efficiently.
Firebox Cleaning and Inspection
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 environ-
ments 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 thoroughly
cleaned annually by a qualified gas technician.
Cleaning Procedure
1. Turn the burner OFF and let the heater cool com-
pletely before cleaning.
2. Lift the Front plate up and then swing the bottom
out to disengage it from the heater shell. (Fig. 25,
Page 15)
3. Remove the screen by lifting up and away from the
unit. Or, if so equipped, remove the glass panel by
rotating the two cams toward the front of the firebox.
Lift the panel up and off of the firebox frame. (Fig.
34)
4. Carefully inspect the log set for damage. Contact
your local dealer if any damage is evident. DO NOT
OPERATE THE HEATER WITH A DAMAGED OR
LOOSE LOG SET.
Use a soft-bristled brush vacuum cleaner attach-
ment to remove dust or debris from the log set, pilot
and burner. Use care as the log set is fragile.
5. Inspect the catalytic combustor at the top of the
firebox. Replace the combustor if any damage or
deterioration is evident.
6. Replace the screen or glass panel and the front
plate. DO NOT OPERATE THE HEATER WITH
THE SCREEN / GLASS PANEL OR FRONT
PLATE REMOVED.
Maintenance
WARNING
Turn the burner Pilot OFF before applying
paint. NEVER paint pilot or around pilot area.
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.
WARNING
Glass Replacement
If so equipped, do not operate this appliance with the
glass panel cracked, broken, or removed. Replace
damaged glass only with an approved ceramic glass
panel. Follow the Cleaning Procedure instructions
regarding parts removal.
Care of Cast Iron
An occasional dusting with a dry rag will help keep the
painted surfaces looking new. Use high-temperature
stove paints, available through your local dealer, to
touch-up areas as needed. Clean areas to be painted
with a wire brush and be sure to cover the log set,
burner and valve assembly. Apply the paint sparingly;
two light coats of paint will give better results than a
single heavy coat.
Porcelain enamel surfaces should be cleaned with
a soft, damp cloth. Do not use abrasive cleaning
agents. If necessary, use only a cleaning agent formu-
lated specifically for use on porcelain enamel surfaces.
