This Owner’s Manual includes accessories commonly
used on this heater. These accessories must be
ordered seperately.
When calling for technical service assistance, or for
other specic information, always have model
number, conguration number and serial number
available. This information is contained on the
dataplate.
This manual will instruct you in the operation and care
of your unit. Have your installer review this manual
with you so that you fully understand the heater and
how it functions.
Contact your local L.B. White distributor or the
L.B. White Co., Inc. for assistance, or if you have
any questions about the use of the equipment or its
application.
The L.B. White Co., Inc. has a policy of continuous
product improvement. It reserves the right to change
specications and design without notice.
The heater is equipped with a burner assembly. The
assembly includes an electronic igniter, solenoid
valves, and burner head with orice. When the heater
is turned ON, the igniter will spark, with gas delivered
through the solenoids to the burner orice. Ignition
will occur.
The burner will heat the heat exchanger. After
a predetermined time frame has passed, a fan
controller will start the main blower motor, and blow
cool air over the heat exchanger. The cool air will be
preheated by passing over the heat exchanger, with
warm, dry air delivered the area to be heated.
Combustion by- products created during the heating
process will be transferred up a vent stack directly to
the outside, thereby providing only clean, dry air to
the heated area.
When the heater is turned OFF, the burner motor is
de-energized turning off the fuel pump. The solenoid
valves will close cutting off fuel to the burner nozzle.
The fan controller will continue to run the main blower
motor for a predetermined period of time to allow the
heat exchanger to cool down. After this time frame
has elapsed, the fan controller will disconnect power
to the fan motor, thereby shutting the fan motor down
completely.

General Installation Instructions
INSTALLATION INSTRUCTIONS
WARNING
Fire and Explosion Hazard
■ Before using this heater, please read this USER’S
MANUAL very carefully. This USER’S MANUAL

how to operate the heater in a safe and efcient
manner.
■ Never leave the heater unattended while burning!
1. Read all safety precautions and follow L. B. White
recommendations when installing this heater.
If during installation or relocating of heater, you
suspect that a part is damaged or defective, call a
qualied service agency for repair or replacement
2. Using a level, make sure the heater is level and
properly positioned before use. Observe and
obey minimum safe distances of the heater to the
nearest combustible materials. Safe distances are
given on page 4 of this manual.
3. This heater may be installed either indoors or
outdoors. For indoor installations, the heater must
be vented to the outside. See installation of inside
structure section of this manual.
4. Heaters used in the vicinity of combustible
tarpaulins, canvas, plastic, wind barriers, or similar
coverings shall be located at least 10 feet/3.05
meters from the coverings. The coverings shall be
securely fastened to prevent ignition or upsetting
of the heater due to wind action on the covering or
other material.
5. Extension cord wire size requirements
• Up to 50ft., use 12 AWG
• Beyond 50ft., use 10 AWG
6. Light according to instructions on heater or within
owner’s manual.
7. The heater must be installed so as not to interfere
with or obstruct normal exits, emergency exits,
doors and walkways.
8. Railing, fencing or suitable substitute materials
must be used to keep the heating equipment from
any people using and visiting the structure.
9. The heater shall be located so that rain, ice, or snow
drainage from the structure does not affect equip-
ment operation. If the heater is mounted outside,
it must be mounted above any pooled or standing
water. If the unit is to be located on the ground, a
surrounding trench is recommended to drain any
rain, ice or snow away from the unit.
10. The ground and surrounding terrain must be
cleared of any combustible vegetation and other
combustible materials when the heater is utilized
outside.
11. Eventually, like all electrical/mechanical devices,
the thermostat can fail. Thermostat failure may re-
sult in an under-heating condition. The thermo-stat
should be tested to make sure it turns the heater
on and off within a temperature differential of ±3°F
(±1.5 °C).
12. Any defects found in performing any of the service
or maintenance procedures must be eliminated and
defective parts replaced immediately. The heater
must be retested by properly qualified service
personnel before placing the heater back into use.
13. Take time to understand how to operate and main-
tain the heater by using this Owner’s Manual.
14. Extension cord wire size requirements
• Up to 50 ft., use 12 AWG
• Beyond 50 ft., use 10 AWG
