Cleaning Instructions; Maintenance Instructions - L.B. White 346JX Owner's Manual And Instructions

This heater contains electrical and mechanical components in the gas management, safety and airflow systems.
Such components may become inoperative or fail due to dust, dirt, wear, aging, or the corrosive atmosphere of an
animal confinement building.
Periodic cleaning and inspection as well as proper maintenance are essential to avoid serious injury or property
damage.
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 use, 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.
Additionally, 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.
c. Observe and obey the Warning within these
Cleaning Instructions. This same Warning is also
supplied on the heater.
1. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines. Also, at this time
have your gas supplier clean out the sediment trap of
any debris that may have accumulated.

3. Regulators can wear out and function improperly.
Have your gas supplier check the date codes on all
regulators installed and check delivery pressures to
the appliance to make sure that the regulator is
reliable.
4. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the
appliance.
