Shut-Down Instructions

For normal shut-down, set the thermostat below room
temperature. When servicing or performing maintenance,
follow steps 1 - 5.
1. Close the fuel supply valve.
2. Allow the heater to burn off any fuel gas remaining in
the gas supply line.

Cleaning Instructions

■
This heater contains electrical and mechanical components in the gas management, and safety systems.
■
Such components may become inoperative or fail due to dust, dirt, wear and aging.
■
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 dir t or dust removed
periodically:
a. Before each use give the heater a general
cleaning using compressed air or a soft brush or
dry rag on its case and internal components. At
this time, dust off the motor case to prevent the
motor from over-heating.
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 blade
assembly. Additionally, make sure the burner air
inlet venturi ports and the casting are free of dust
accumulation.

Maintenance Instructions

1. The area surrounding the heater shall be kept clear
and free from combustible materials, gasoline, and
other flammable vapors and liquids.
2. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines.
3. 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 heater.
4. 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 heater to make sure that the regulator is reliable.

3. Set the thermostat to "Off" or "No Heat".
4. Position selector switch to O (off).
5. Disconnect the heater from its gas and electrical
supplies.
WARNING
Fire, Burn, and Explosion Hazard
Do not use a pressure washer, water, or liquid cleaning
solution on any gas controls. Use of a pressure washer,
water, or liquid cleaning solution on the control
components can cause severe personal injur y or
property damage due to water and/or liquids:
■ In electrical components, and wires causing electrical
shock or equipment failure.
■ On gas control valves causing corrosion which can
result in gas leaks and fire or explosion from the leak.
Clean all components of the heater with pressurized air,
a dry brush, or a dry cloth.
5. Check all wiring, associated terminals, and electrical
components within the heater for corrosion, frayed or
cut insulation, tight connections, etc. Repair or
replace as necessary.
6. Review all heater markings (i.e. wiring diagram,
warnings, start-up, shut-down, troubleshooting, etc.)
at the time of maintenance for legibility. Make sure
none are cut, torn, or otherwise damaged. Any
damaged markings must be replaced immediately by
contacting the L.B. White Co., Inc. Dataplates, start-
up and shut-down instructions and warnings are
available at no cost. A nominal charge will be applied
for wiring diagrams.
