General Installation Instructions
WARNING
Fire or explosion hazard.
Can cause property damage, severe injury or death.
1. Disconnect the power supply before wiring to
prevent electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas, turn
off gas supply at the appliance service valve before
starting installation, and perform gas leak test after
completion of installation.
3. Do not force the gas control knob. Use only your
hand to turn the gas control knob. Never use any
tools. If the knob will not operate by hand, the
control should be replaced by a qualified service
technician. Force or attempted repair may result in
fire or explosion.
1. Read all safety precautions and follow L. B. White
recommendations when installing this heater. If
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 and is hung level. Observe and obey all mini-
mum 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 must have the proper gas regulator
installed for the application. A regulator must be
connected to the gas supply so that gas pressure
at the inlet to the gas valve is regulated within
the range specified on the dataplate at all times.
Contact your gas supplier, or the L.B. White Co.,
Inc. if you have any questions.
5. The unit's gas regulator (with pressure relief valve)
should be installed outside of building. Any regula-
tors inside buildings must be properly vented to the
outside. Local, state and national codes always ap-
ply to regulator installation. Natural gas regulators
with vent limiting device may be mounted indoors
without venting to outdoors.
6. All gas pressure regulators must be installed in
strict accordance with the manufacturer's safety
instructions. The instructions accompany each
regulator.

7. Ensure 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. Ensure that a sediment trap is installed 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
fire or explosion causing loss of products, build-
ing 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.
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.
10. Check all connections for gas leaks using ap-
proved 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.
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 dam-
age, personal injury or loss of life.
-- 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.
