AIR DIVERTER
INSTALLATION INSTRUCTIONS
12. Ensure 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.
13. This heater can be configured for use with either L.P.
gas vapor withdrawal or natural gas. Consult the
dataplate, located on interior of the burner end or
motor end door, for the gas configuration of the
specific heater. 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.
14. 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.
15. Take time to understand how to operate and maintain
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.
16. 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.

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. See Fig. 1.
2. The air diverters may require hand forming prior to
installation. Make 90 degree bends utilizing the
perforations provided. Diverters should have the
shape as shown in Fig. 1.
3. The air diverter’s tabs on each half will “pop” into the
blower outlet between the inside of the case assembly
and the blower housing outlet. If the notched tabs do
not “pop” into the blower outlet, loosen (do not
remove) the blower outlet screws. Doing this provides
a gap into which you can insert the tabs. Retighten
the screws after installation.
