SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensor
(ODS) safety shut off system. The ODS/pilot shuts off the
heater if there is not enough fresh air.
IGNITION SYSTEM / BATTERY INSTALLATION
The heater is equipped with an electronic manual igniter.
This system requires no matches, batteries, or other source
to light heater but does require one AA battery to operate
igniter.
To install or replace battery unscrew the igniter cap (red
button), insert battery positive (+) terminal up and replace
cap. (AA Battery included)
LOCAL CODES
Install and use heater with care.
Installation must conform to local codes or in the absences
of local codes, use the latest edition of National Fuel Gas
Code ANSI Z223.1/NFPA 54.
UNPACKING
1.
Remove heater from carton.
2. Remove all protective packaging applied to heater
for shipment.
3. Check heater for any shipping damage. If heater
is damaged, promptly inform dealer where you
bought heater.
FRESH AIR FOR COMBUSTION AND VENTILATION
WARNING: This heater shall not be installed in a confined
space or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air. Read
the following instructions to insure proper fresh air for this
and other fuel-burning appliances in your home.
ESTABLISHING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code,
NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion
and Ventilation. All spaces in homes fall into one of the
three following ventilation classifications:
1.
Unusually Tight Construction
2. Unconfined Space
3. Confined Space
This heater must not be installed in a confined space
or unusually tight construction unless provisions are
provided for adequate combustion and ventilation air. The
information on pages 4 and 5 will help you classify your
space and provide adequate ventilation.
Unusually Tight Construction
If your home meets all of the three following criteria you
must provide additional fresh air. See Ventilation from
Outdoors, page 5.
Unusually tight construction is defined as construction
where:
a. Walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating
kg per pa-sec-m
-11
of one perm (6 x 10
2
) or less with
Universal Unvented Room Heater
openings gasketed or sealed and
b. Whether stripping has been added on operable
windows and doors, and
c. Caulking or sealants are applied to areas such as joints
around windows and door frames, between wall-
ceiling joints, between wall panels, at penetrations
for plumbing, electrical, and gas lines, and at other
openings.
If you home does not meet all of the three criteria above,
see Determining the Type of Heater Location Space, below.
Confined Space and Unconfined Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1 defines
a confined space as a space whose volume is less than 50
cubic feet per 1,000 Btu per hour (4.8 m
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
m
3
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.
*Adjoining rooms are communication only if there are
odorless passageways or ventilation grills between
them.
DETERMINING THE TYPE OF HEATER LOCATION
SPACE:
Use this method to determine if you have a confined or
unconfined space.
Note: the space includes the room in which you
install heater plus any adjoining rooms with doorless
passageways or ventilation grills between the rooms.
1. Find the volume of the space by multiplying room length
x width x height.
Example: Space size 18ft (length) x 18ft. (width) x 8ft.
(height) = 2592
If additional ventilation to adjoining room is supplied with
grills or openings, add the volume of these rooms to the
total volume of the space.
2. Divide the space volume by 50 cubic feet to determine
the maximum Btu/hr the space can support.
Example: 2592 cu.ft. (volume of space) / 50 cu.ft. =
51.8 or 51,800 (maximum Btu/hr the space
can support)
WARNING: This heater shall not be installed in a
room or space unless the required volume of indoor
combustion air is provided by the method described
in the National Fuel Gas Code, ANSI Z223.1/NFPA
54, the International Fuel Gas Code, or applicable
local codes
3. Add the Btu/hr of all the fuel-burning appliances in the
space such as, Vent–free heater, Gas water heater, Gas
furnace, Vented gas heater, Gas fireplace logs, and
Other gas appliances*
