1.
Have your authorized gas supplier check all gas
piping annually for leaks or restrictions in
the
gas
lines.
Also at this time have your gas supplier
perform the following scope of service
program
recommended by the L.B. White
Company.
a.
Review all heater markings priors to use.
Markings constitute information relating to
warnings, start-up, shut-down instructions,
etc.
Any damaged markings should be
replaced
immediately. Contact the L.B. White
Company
for replacement.
b.
Check the regulators
delivery pressures to
the
appliance to make sure the regulator
is
reliable. Regulator vents should be
inspected
for blockage.
A blocked vent will
cause excess
pressure at the appliance.
1. Before cleaning, shut off all gas supply valves and
disconnect electrical supply.
2. The heater should have dirt or dust removed
periodically:
a. After each flock or between building re-population,
give the heater a general cleaning using
compressed air or a soft brush on its interior and
exterior. At this time, dust off the motor case to
prevent the motor from over-heating and shutting
the heater down.
b. At least once a year, give the heater a thorough
cleaning. At this time, remove the fan and motor
assembly and brush or blow off the fan wheel,
giving attention to the individual fan blades. Make
sure the burner air inlet venturi ports and the
“throat” of the casting are free of dust
accumulation and the area between the heat
chamber top and inside case is also free of dust.
Additionally, the igniter and flame sensor
assembly should be removed and cleaned in
accordance to the service instructions within this
Owner’s Manual.
c. If washing with water, observe and obey the
Warning within these Cleaning Instructions. This
same Warning is also supplied on the heater.
WARNING
This heater may be washed only on the external case
assembly provided:
A.
The heater is disconnected from the electrical
supply.
B. All access panels are securely closed.
C. Water spray nozzle shall not discharge within 1.83 m
of the heater.
D. The water pressure does not exceed 3.1 BAR for 10
seconds on each side of heater.
E.
The heater is not reconnected to electrical supply for
a minimum of 1 hour or until the heater is thoroughly
dry.
Improper cleaning of the heater can cause severe
personal injury or property damage due to water and/or
cleaning solution:
1. In electrical components, connections and wires
causing electrical shock or component failure.
2. On gas control components causing corrosion which
can result in gas leaks and fire or explosion from the
leak.
Clean internal components of the heater with a soft, dry
brush or cloth, or compressed air.
