have your gas supplier clean out the sediment trap of
any debris that may have accumulated.

insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the
appliance.

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.

components within the heater for corrosion, frayed or
cut insulation, tight connections, etc. Repair or
replace as necessary.

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, and troubleshooting markings.
