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. This heater can be configured for use with either L.P.
vapor withdrawal or natural gas. Consult the
dataplate, located on the blower outlet side of the
case assembly, 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 PSI.
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 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.
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.
17. Do not exceed the input rating stamped on the
dataplate of the heater. Do not exceed the burner
manifold pressure stated on the dataplate. Do not
use an orifice size different than specified for the
specific input rating of this heater, fuel type
configuration and altitude.
