General Installation Instructions
1. Read all safety precautions and follow L. B. White
recommendations when installing this heater. If
during the installation or relocating of the heater,
you suspect that a part is damaged or defec-
tive, call a qualifi ed service agency for repair or
replacement.
2. Position the heater properly before use in ac-
cordance with requirements for combustible clear-
ances, ground clearance, tilt angle, and to protect
the heater from livestock. Refer to Fig. 2 as well as
the specifi cation table on page 4 in this manual, for
information on installation and clearances.
3. Position the gas hose outside of the hot zone
directly above the heater to avoid any contact with
the hot surface of the heater's canopy. Refer to
Fig. 2.
4. Insure that all accessories that you have ordered
for the heater have been removed from inside of
heater's shipping container and installed. This
pertains to gas hose, fi lters,etc.
5. The heater's gas regulator (with pressure relief
valve) should be installed outside of building. Any
regulators inside the buildings must be properly
vented to the outside. Local, state and national
codes always apply to regulator installation. Natu-
ral gas regulators with a vent limiting device may
be mounted indoors without venting to outdoors.
6. Any regulator mounted outside the building be
protected against the weather, particularly ice
formation. Ice formation can lead to overpressur-
ization of the regulator and subsequent gas leaks.
See codes covering proper protection.
7. Always use pipe joint compound that is resistant to
liquefi ed petroleum gas natural gas.
8. Check all connections for gas leaks using ap-
proved gas leak detectors. Gas leak testing is
performed as follows:
WARNING
Fire, Burn, 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 dam-
age, personal injury or death.
I-40 Manual and Spark Ignition
-- 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.
-- Further 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 fl ashback.
-- With the main burner in operation, check all hose
connections, fi ttings 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 identifi ed and
repaired before proceeding.
9. A qualifi ed service agency must check for proper
operating gas pressures upon installation of the
heaters.
10. Use the proper gas supply line to assure
proper functioning of the heaters. Typically, 3/4
in. ID black iron pipe is used to supply gas to
the inlet of the zone control panel with 1/2 in.
ID black iron pipe used to convey the gas to
the heaters. However, always consult your fuel
gas supplier, or the L. B. White Co., Inc. for
proper line sizing and installation.
