L.B. White Sentinel Radiant Tube AT150 40' Center Mount - Manual (Page 10)

7. Position the gas hose to prevent any contact with the
tubes, heat relectors, and burner box.
8. Ensure that all accessories that ship with the heater
have been removed from shipping containers and
installed. This pertains to gas hose, regulators,
supports, hangers, etc.
9. This heater requires a regulated gas supply to its gas
inlet :
-- The regulator must be the proper design for the
application.
-- The regulator must control the inlet pressure to
the heater within the range specified on the
dataplate.
-- Regulators mounted outside must be protected
from adverse weather conditions.
-- Regulators with pressure relief valves should be
installed outside the building.
-- Regulator installed inside should be vented
outside.
-- Local state and national codes apply to regulator
installation. Refer to NFPA 54, National Fuel Gas
Code, and NFPA 58, Standard for Storage and
Handling of Liquified Petroleum Gas.
10. Always use pipe joint compound that is resistant to
liquefied petroleum gas and natural gas.
11. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:
-- Check all pipe connections, hose connections,
fittings 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
application of pipe compound before further
tightening.
-- Tighten the gas connections as necessary 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
connections, 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 application of pipe compound before
further tightening.
-- 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.
12. Install a sediment trap at the gas valve inlet to
prevent foreign materials (pipe compound, pipe chips
and scale) from entering the gas valve. Debris blown
i n to t h e g a s va l ve m ay c a u s e t h a t va l ve to
malfunction resulting in a serious gas leak that could
result in a possible fire or explosion causing loss of
products, building or even life. A properly installed
sediment trap will keep foreign materials from
e n te r i n g t h e g a s va l ve a n d p rote c t t h e s a fe
functioning of that important safety component.
13. Any heater connected to a piping system must have
an accessible, approved manual shut of f valve
installed within six feet (6 ft.) of the heater it serves.
14. Install the proper gas supply line to assure proper
functioning of the heaters. Consult your fuel gas
supplier, or the L.B. White Co., Inc. for proper line
sizing and installation.
15. Light according to instructions on heater or within
Owner’s Manual.
16. The heater is designed for L.P. vapor withdrawal or
natural gas only. Do not use this heater in a propane
liquid withdrawal system. Do not permit propane in
liquid form to enter the heater at any time.
17. T h e c o r ro s i ve a t m o s p h e r e p r e s e n t i n a n i m a l
confinement buildings can cause component failure
or heater malfunction. The heater should be
periodically inspected and cleaned in accordance
with the Maintenance and Cleaning Instructions in
this manual. Make sure that livestock is protected by
a back up alarm system that limits high and low
temperatures and also activates appropriate alarms.
18. Take time to understand how to operate and maintain
the heater using the owner’s manual. Make sure you
know how to shut off the gas supply to the building
and to the heater. Contact your gas supplier if you
have any questions.
19. Any defects found in performing any of the service
procedures must be eliminated and defective parts
replaced immediately. Retest the heater before
placing it back into service.
20. Do not exceed input rating stamped on the dataplate
of the heater. Do not exceed the burner manifold
pressure stated on the dataplate. Do not use an
orifice size different than specified for the specific
input rating of this heater, fuel type configuration and
altitude.
