L.B. White AW250(Smart Box controller) - Manual (Page 9)

12. A qualified service agency must check for proper
operating gas pressure upon installation of the
heater.
13. Light according to instructions on heater or within
owner's manual.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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 ser vice
personnel before placing the heater back into use.
19. Do not exceed 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.
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. 2.
2. The air diverters may require hand forming prior to
installation. Make 90 degree bends utilizing the
performations provided. Diverter should then have
the shape shown in Fig. 2.
3. The air diverter’s tabs on each half will pop into the
b l owe r o u t l e t b e t we e n t h e i n s i d e o f t h e c a s e
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.
