objects on the heater.
6. This heater needs fresh, outside air ventila-
tion to run properly. This heater has an Oxy-
genDepletionSensing(ODS)safetyshutoff
system. The ODS shuts down the heater if
not enough fresh air is available. See Air for
Combustion and Ventilation, page 5.
7. Keep all air openings in front and bottom
of heater clear and free of debris. This will
insure enough air for proper combustion.
Surface of heater becomes very
hot when running heater. Keep
children and adults away from
hot surface to avoid burns or
clothing ignition. Heater will
remain hot for a time after shut-
down. Allow surface to cool
before touching.
8. If heater shuts off, do not relight until you
provide fresh, outside air. If heater keeps
shutting off, have it serviced.

AIR FOR COMBUSTION AND VENTILATION
Unusually Tight Construction
WARNING: This heater shall

National Fuel Gas Code, ANSI
Z223.1/NFPA54,theInternational
Fuel Gas Code, or applicable lo-
cal codes. Read the following in-
structionstoinsureproperfresh
airforthisandotherfuel-burning
appliances in your home.
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined as
construction where:
a. walls and ceilings exposed to the out-
side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6x10-11 kg per pa-sec-m2) or
less with openings gasketed or sealed
and
b. weather stripping has been added on
openable windows and doors and
Today’s homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out and the warm air in. Dur-
ing heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.
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,youmustprovideadditionalfreshair.
See Ventilation Air From Outdoors, page 7.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow For Heater Location.
Exhaust fans, heaters, clothes dryers and fuel
burning appliances draw air from the house to
operate. You must provide adequate fresh air
Confined Space and Unconfined Space
The National Fuel Gas Code ANSI Z223.1/
NFPA54 defines a confined space as a space
for these appliances. This will insure proper whose volume is less than 50 cubic feet per
1,000 Btu per hour (4.8 m3 per kw) of the ag-

vENTILATION
The following are excerpts from National Fuel
Gas Code. ANSI Z223.1/NFPA 54, 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
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 un-
confined space.
* Adjoining rooms are communicating only if
there are doorless passageways or ventilation
grills between them.
The information on pages 5 through 7 will
help you classify your space and provide
adequate ventilation.

THERMOSTAT CONTROL
CAUTION: Label all wires
prior to disconnection when
servicingcontrols.Wiringerrors
cancauseimproperanddanger-
ous operation.
OPERATION
The thermostatic control used on these
models differs from standard thermostats.
Standard thermostats simply turn on and off
the burner. The thermostat used on this heater
senses the room temperature. At times the
room may exceed the set temperature. If so,
the burner will shut off. The burner will cycle
back on when room temperature drops below
the set temperature. The control knob can be
set to any comfort level between 1 and 5. All
plaques will turn off and on.
CAUTION:Donotplugpower
cord into electrical outlet until
installation is complete.
Extension Cord
Use extension cord if needed. The cord must
have a three-prong, grounding plug and a
three-hole receptacle. Make sure cord is in
good shape. It must be heavy enough to carry
the current needed. An undersized cord will
cause a drop in line voltage. This will result in
loss of power and overheating. Use a No. 16
AWG cord for lengths less than 50 feet.
Note: The thermostat sensing bulb mea-
sures the temperature of air near the heater
cabinet. This may not always agree with
room temperature (depending on housing
construction, installation location, room size,
open air temperatures, etc.) Frequent use of
your heater will let you determine your own
comfort levels.
MANUAL LIGHTING
PROCEDURE
1. Remove front panel (see Figure 7, page 9).
CAUTION: Verify proper op-
eration after servicing.
Operating Blower
2. Follow steps 1 through 5 under Lighting
Instructions, page 14.
The blower is connected to a thermostat.
When unit heats up, the blower will operate.
Afew minutes after unit cycles off or is turned
off, blower will shut off. Blower will cycle on
and off in this manner. Note: If you have a
heater with a thermostat, the heater and
blower will not turn off and on at exactly the
same time. Blower cycle times will vary with
heat setting selected.
3. With control knob pressed in, strike match.
Hold match to pilot until pilot lights.
4. Keep control knob pressed in for 30 sec-
onds after lighting pilot. After 30 seconds,
release control knob. Now follow step 9
