operating gas pressure upon installation of the
heater.
8. Light according to instructions on heater or within
owner's manual.
9. Make sure the heater has the proper gas
regulator for the application. A regulator must be
connected to the gas supply so that gas pressure
at the inlet to the gas valve is regulated within the
range specifi ed on the dataplate at all times.
Premier 350DF heaters: The regulator sup-
plied with the heater is suitable for use with propane
gas or natural gas.
Premier 350 Propane Gas heaters: The
regulator supplied with these heaters is designed for
use specifi cally for the fuel being used.
Contact your gas supplier, or the L.B. White Co., Inc.

13. The heater shall be located so that rain, ice,
or snow drainage from the structure does not
affect equipment operation. If the heater is
mounted outside, it must be mounted above
any pooled or standing water. If the unit is
to be located on the ground, a surrounding
trench is recommended to drain any rain, ice
or snow away from the unit.
14. The ground and surrounding terrain must be
cleared of any combustible vegetation and
other combustible materials when the heater
is utilized outside.
15. Eventually, like all electrical/mechanical
devices, the thermostat can fail. Thermo-
stat failure may result in an underheating
condition. The thermostat should be tested
to make sure it turns the heater on and off
within a temperature differential of ±3°F
(±1.5 °C).
16. Take time to understand how to operate and
maintain the heater by using this Owner's
Manual. Make sure you know how to shut
off the gas supply to the building and also to
the individual heater. Contact your fuel gas
supplier if you have any questions.

service or maintenance procedures must
be eliminated and defective parts replaced
