use the brood heater in an L.P. gas liquid 
withdrawal system or application.  If you are 
in doubt, contact the L. B. White Co., Inc.

17.  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.

18.  Take time to understand how to operate 

and maintain the brood 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 brood heater.  Contact 
your fuel gas supplier if you have any ques-
tions.

19.  Any defects found in performing any of the 

service or maintenance procedures must 
be eliminated and defective parts replaced 
immediately.  The brood heater must be
