SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sen-
sor (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 
ignitor. This system requires no matches, or other 
source to light heater, but does require one AA battery 
to operate ignitor. (AA Battery included).
To install or replace battery unscrew the ignitor cap 
(red button), insert battery positive (+) terminal up 
and replace cap.
(AA Battery included)
THERMOSTATIC CONTROL
These heaters have a control valve with a thermostat 
sensing bulb. This results in the greatest heater comfort 
and may result in lower bills.
BLOWER FAN CONTROL SWITCH OPERATION
These heaters also include an electrical blower. The 
blower switch has three positions: MANUAL, OFF and 
AUTO. In AUTO, the blower will turn on and off as the 
heater cycles on and off. On MANUAL, the blower will run 
continuously. To turn blower off, use the OFF position.
LOCAL CODES

FRESH AIR FOR COMBUSTION AND 
VENTILATION
WARNING: This heater shall not be installed in 
a conned 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 Com-
bustion and Ventilation. All spaces in homes fall into 
one of the three following ventilation classications:
1.  Unusually Tight Construction
2.  Unconned Space
3.  Conned Space
This heater must not be installed in a conned space 
or unusually tight construction unless provisions are 
provided for adequate combustion and ventilation air. 
The information on pages 4 through 6 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 Air 
from Outdoors, page 6.
Unusually tight construction is dened as construction 
where:
a. Walls and ceilings exposed to the outside atmo-
sphere have a continuous water vapor retarder with 
a rating of one perm (6 x 10
-11
 kg per pa-sec-m
2
) 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 windows and door frames, 
between wall-ceiling joints, between wall panels, at 
penetrations for plumbing, electrical, and gas lines, 
and at other openings. 
If your home does not meet all of the three criteria 
above, see Deterzmine the Type of Heater Location 
Space, page 5.
Conned Space and Unconned Space
The National Fuel Gas Code, NFPA 54/ ANSI Z223.1 
denes a conned space as a space whose volume is 
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, and an unconned 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 fur-
nished with doors, are considered a part of the uncon-
ned space.
