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.

The standing pilot incorporates an Oxygen Depletion
System (ODS/pilot) designed to shut off the appliance if
enough fresh air is not available.
Fresh Air Requirements for Combustion
and Ventilation
WARNING
This heater must have fresh air for proper operation. If not, poor fuel combustion could result. Read
the following instructions to insure proper fresh
air for this and other fuel-burning 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 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.
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 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.
20007068
7
UVS27 Vent-Free Gas Heater
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 sup-
port.
Example:
3840 divided by 50 = 76.8 or 76,800 BTU/Hr.
3. Add the BTU/Hr ratings of all fuel-burning appliances
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 appliances, the space is considered to be Confined space.
Additional air must be provided to meet the requirements of the Unvented heater.
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 3.
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.
W A R N I N G
This heater shall not be installed in a confined
space or unusually tight construction unless
provisions are made for adequate combustion
and ventilation air.
W A R N I N G
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.
