L.B. White I-5 Infraconic - Manual (Page 7)

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 defective, call a
qualified service agency for repair or replacement.
2. Position the heater properly before use in accordance
with requirements for combustible clearances, ground
clearance, tilt angle, and to protect the heater from
livestock. Refer to Fig. 2 as well as the specification
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
canopy surface of the heater. Refer to Fig. 2.
4. Insure that all accessories that ship with heater have
been removed from inside of heater’s shipping
container and installed. This pertains to gas hose,
regulators, 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. Natural 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, par ticularly ice
fo r m a t i o n . I c e fo r m a t i o n c a n l e a d to
overpressurization of the regulator and subsequent
gas leaks. See codes covering proper protection.
7. Always use pipe joint compound that is resistant to
liquefied petroleum gas and natural gas.
8. 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.
-- Furthermore 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.
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 damage,
personal injury or death.

Installation Instructions
GENERAL
14. A qualified service person shall inspect the heater and
its gas train at least on an annual basis. This should
consist of, but is not limited to, the following points of
action:
-- Start-up and shut down of the heaters and zone
control panel to test for proper operation.
-- Leak check of all pipe joints and hose connections.
-- Thorough cleaning of the exterior of the heater, its
combustion cones and filter.
-- Thorough inspection of the heater’s component parts
for corrosion, stripped threads, etc. with subsequent
parts replacement as necessary.
-- Gas pressure checks.
15. Turn off the gas supply when the heater is not in use.
