13. 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.
14. 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.
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.
3. The air diverters require hand forming prior to
installation.
Make 90 degree bends utilizing the
perforations provided. The diverter halves should then
have the shape as shown in Fig. 1.
15. Any defects found in performing any of the service or
maintenance procedures must be eliminated and
defective parts replaced immediately.
must be retested by properly qualified service
personnel before placing the heater back into use.
