Guardian LP or Natural Gas Heater

Maintenance Instructions

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.
2. The heater's surrounding area
shall be kept clear and free from
combustible materials, gasoline,
and other flammable vapors and
liquids.
3. Regulators can wear out and function improp-
erly. 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.
5. Review all heater markings (ie. warnings,
start-up/shutdown, electrical wiring, diagrams,
etc.) for legibility. Ensure that none are cut,
torn, or otherwise damaged. Any damaged
markings must be replaced immediately by
contacting L.B. White Co., Inc. Markings are
available at no cost.
6. Before each use, inspect gas hoses for
nicks,cuts, or corroded fittings. Replace
the complete gas hose assembly if
defects are found.
7. Inspect the heater's electrical connections and
wiring. Replace any terminals that are cor-
roded and any wires that are cut or nicked.
