■ Reducing the number of bends will ensure that the
warm air exiting the heater flows freely, thereby pre-
venting overheating. If there are excessive bends,
the high limit switches may open.
4. Heaters used in the vicinity of combustible
tarpaulins, canvas, plastics, wind barriers, or similar
coverings shall be located at least 10 ft./3.05 meters
from the coverings. The coverings shall be securely
fastened to prevent ignition or upsetting of the
heater due to wind action on the covering or other
material.
5. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed
as follows:
-- Check all pipe connections, hose connections, fit-
tings and adapters upstream of the gas control with
approved gas leak detectors.
-- In the event a gas leak is detected, check the
components involved for cleanliness and proper ap-
plication of pipe compound before further tightening.
-- Furthermore, tighten the gas connections as neces-
sary to stop the leak.
-- After all connections are checked and any leaks are
stopped, turn on the main burner.
-- Stand clear while the main burner ignites to prevent
injury caused from hidden leaks that could cause
flashback.
-- With the main burner in operation, check all connec-
tions, hose connections, fittings and joints as well
as the gas control valve inlet and outlet connections
with approved gas leak detectors.
-- If a leak is detected, check the components involved
for cleanliness in the thread areas and proper ap-
plication of pipe compound before further tightening.
WARNING
Fire and Explosion Hazard
■ Do not use open flame (matches, torches,
candles, etc.) in checking for gas leaks.
■ Use only approved leak detectors.
■ Failure to follow this warning can lead to fires
or explosions.
■ Fires or explosions can lead to property dam-
age, personal injury or loss of life.
-- Tighten the gas connection as necessary to stop
the leak.
-- If necessary, replace the parts or components
involved if the leak cannot be stopped.
-- Ensure all gas leaks have been identified and
repaired before proceeding.
6.
A qualified service agency must check for proper
operating gas pressure upon installation of the
heater.
7.
Light according to instructions on heater or within
owner’s manual.
8.
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 specified on
the dataplate at all times.
• The regulator supplied with the Premier 350DF
2.0 heater is suitable for use with propane gas
and natural gas.
• Contact your gas supplier, or the L.B. White Co.,
LLC. if you have any questions.
6.
The heater must be installed so as not to interfere
with or obstruct normal exits, emergency exits, doors
and walkways.
7.
Railing, fencing or suitable substitute materials
must be used to keep the heating equipment from
any people using and visiting the structure.
8.
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.
9.
The ground and surrounding terrain must be
cleared of any combustible vegetation and other
combustible materials when the heater is utilized
outside.
10.
Eventually, like all electrical/mechanical
devices, the thermostat can fail. Thermostat failure
may result in an underheating condition. The
thermostat should be tested to make sure it turns.
