-- Regulators mounted outside must be protected
from adverse weather conditions.
-- Regulators with pressure relief valves should be
installed outside the building.
-- Regulators 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 Liquifi ed Petroleum Gas.
8. Always use pipe joint compound that is resistant to
liquefi ed petroleum gas and natural gas.
9. Check all connections for gas leaks using ap-
proved gas leak detectors. Gas leak testing is
performed as follows:
WARNING
Fire and Explosion Hazard
■ Do not use open fl ame (matches, torches,
candles, etc.) in checking for gas leaks.
■ Use only approved leak detectors.
■ Failure to follow this warning can lead to fi res
or explosions.
■ Fires or explosions can lead to property
damage, injury or death.
-- Check all pipe connections, hose connections,
fi ttings 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 pre-
vent injury caused from hidden leaks that could
cause fl ashback.
-- With the main burner in operation, check all con-
nections, hose connections, fi ttings and joints as
well as the gas control valve inlet and outlet.
-- If a leak is detected, check the components
involved for cleanliness in the thread areas and
proper application of pipe compound before
Sentry Tube Heaters
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 identifi ed and repaired
before proceeding.
10. 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 into
the gas valve may cause that valve to malfunction
resulting in a serious gas leak that could result in a
possible fi re or explosion causing loss of products,
building or even life. A properly installed sediment trap
will keep foreign materials from entering the gas valve
and protect the safe functioning of that important
safety component.
11. Any heater connected to a piping system must
have an accessible, approved manual shut off valve
installed within six feet (6 ft.) of the heater it serves.
12. Install the proper size of 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.
13. Light according to instructions on heater or within
Owner's Manual.
14. 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.
15. The corrosive atmosphere present in animal confi ne-
ment buildings can cause component failure or
heater malfunction. The heater should be periodically
inspected and cleaned in accordance with the Mainte-
nance 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.
16. 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.
