14. This heater can be configured for use with either L.P.
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.
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 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.
2. 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.
