General Installation Instructions
WARNING
Burn 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 qualifi ed service
technician. Force or attempted repair may result in
fi re 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
qualifi ed 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 may be used installed indoors or
outdoors. When the heater is installed outdoors,
use only the ductwork supplied in the outdoor
mounting kit.
4. For heaters intended for outdoor installation, the
heater is to be installed at least 18 inches above
the ground or to a height that would prevent snow
blockage of heater's air inlet.
5. 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 specifi ed on the dataplate at all times.
Contact your gas supplier, or the L.B. White Co.,
Inc. if you have any questions.
6. The heater's gas regulator (with pressure relief
valve) should be installed outside of building. Any
Guardian LP or Natural Gas Heater
regulators inside the buildings must be properly
vented to the outside. Local, state and national
codes always apply to regulator installation.
7. All gas pressure regulators must be installed in
strict accordance with the manufacturer's safety
instructions. These instructions accompany each
regulator.
8. Ensure that all accessories that ship with the
heater have been installed. This pertains to air
diverters, hose, regulators, etc.
9. Make certain that a sediment trap is installed at
the gas inlet to prevent foreign materials (pipe
compound, pipe chips and scale) from entering
the gas valve. Debris blown into the gas valave
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, 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.
10. 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.
11. Check all connections for gas leaks. Gas leak
testing is performed as follows:
-- Check all pipe connections, hose connections,
fi ttings and adapters upstream of the gas control
with approved gas leak detectors.
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 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.
