1. Disconnect power supply before wiring to prevent
electrical shock or heater damage.
2. To avoid dangerous accumulation of fuel gas, turn
off gas supply at the heater service valve before
starting installation, and perform gas leak test after
completion of installation.
1. Read all safety precautions and follow L. B. White
recommendations when installing this heater.
during the installation or relocating of heater, you
suspect that a part is damaged or defective, call a
qualified service agency for repair or replacement.
2. Make sure the heater is properly positioned before
use. Observe and obey all minimum safe distances of
the heater to the nearest combustible materials.
Minimum safe distances are given on the heater
nameplate and on page 4 of this manual.
3. The heater is approved for indoor use only.
4. The heater shall be installed so that it is not directly
exposed to water spray, rain, and dripping water.
5. Certified construction heaters include a gas hose and
single-stage regulator. The single-stage regulator is to
be used only in applications where temporary use of
the heater is required. Contact the L.B. White Co. or
your fuel gas supplier if you have questions.
6. For permanent heater installations, two-stage gas
regulation is required.
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 vent
limiting device may be mounted indoors without
venting to outdoors.
7.
Insure that all accessories that ship within the heater
have been removed from inside of heater and
installed.
This pertains to air diverters, hose,
regulators, etc.
8. Make certain that a sediment trap is installed near 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 fire or explosion
causing loss of products, building or even life.
properly installed sediment trap will keep foreign
materials from entering the gas valve and protect the
safe functioning of that important safety component.
9. 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.

10. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:
Fire a a nd E E xplosion H H azard
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,
If
personal injury or loss of life.
-- 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.
11. A qualified service agency must check for proper
operating gas pressure upon installation of the heater.
12. Light according to instructions on heater or within
A
owner's manual.
13. It is extremely important to use the proper size and
type of gas supply line to assure proper functioning of
the heater. Contact your fuel gas supplier for proper
line sizing and installation.
