1.
Optional air diverters can be installed in the heater
outlet to provide direction to the heated air as it exits
the heater. Installation options include installing the
diverters in such a way as to broadly distribute the air
in two 45 degree paths or to focus the air flow in one
45 degree direction.
2.
Locate the air diverter tabs into the blower outlet
between the inside of the case assembly and the
blower housing outlet. If the notched tabs do not
easily position into the blower outlet, loosen the
blower outlet screws. Doing this provides a gap into
which you can insert the tabs. Retighten the screws
after installation.

11.
Light according to instructions on the heater or within
owner’s manual.
12. It is extremely important to use the proper size and
type of gas supply line to assure proper functioning of
the heater. Contact your fuel gas supplier for proper
line sizing and installation.
13. Make sure the heater has the proper gas regulator for
the application. A regulator must be connected to the
gas supply so that gas pressure at the inlet to the gas
valve is regulated within the range specified on the
dataplate at all times. Contact your gas supplier, or
the L. B. White Co., Inc. if you have any questions.
14. This heater is configured for use with either L.P. vapor
withdrawal only. Do not use the heater in an L.P. gas
liquid withdrawal system or application. If you are in
doubt, contact the L. B. White Co., Inc.
15. Eventually, like all electrical/mechanical devices, the
thermostat can fail. Thermostat failure may result in
either an underheating or overheating condition which
may damage critical products and/or cause animal
injury or death. Critical products and/or animals
should be protected by a separate back-up control
system that limits high and low temperatures and also
activates appropriate alarms.
16. Take time to understand how to operate and main-
tain the heater by using this Owner’s Manual. Make
sure you know how to shut off the gas supply to the
building and also to the individual heater. Contact
your fuel gas supplier if you have any questions.
17. 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 ser vice
personnel before placing the heater back into use.
