1. The area surrounding the heater shall be kept clear
and free from combustible materials, gasoline, and
other flammable vapors and liquids.

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.
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.

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
