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 injury 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 fi re or
explosion from the leak.
Clean all components of the heater with pressurized air,
a dry brush, or a dry cloth.

Maintenance Instructions

BEFORE EACH USE:
■ Check the area surrounding the heater to ensure it is
clear and free of combustible materials, gasoline, and
other fl ammable vapors and liquids.
■ At the installation, ensure the fl ow of combustion and
ventilation air is not obstructed.
■ Have your gas supplier check all gas connections for
leaks or restrictions in gas lines.
■ Inspect the regulator vent to make sure the regulator
vent is not blocked. Debris, insects, insect nests,
snow, or ice on a regulator can block vents and cause
excess pressure at the heater.
■ 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.
■ Review all heater markings (i.e. wiring diagram, warn-
ings, 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
