1. Read all safety precautions and follow L.B. White recom-
mendations 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 minimum safe dis-
tances 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 either indoors or outdoors. 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.
Refer to instructions provided in the optional L.B. White
outdoor mounting and ducting kit - part number 500-23579.
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.,
LLC. if you have any questions.
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 vent limiting device
may be mounted indoors without venting to outdoors.
6. All gas pressure regulators must be installed in strict ac-
cordance with the manufacturer's safety instructions. These
instructions accompany each regulator.
7. Insure that all accessories that ship within the heater have
been removed from inside of heater and installed. This
pertains to air diver ters, hose, regulators, etc.
8. Make certain 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 malfunc-
tion resulting in a serious gas leak that could result in a
possible fire or explosion causing loss of products, building
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 it serves.
10. Check all connections for gas leaks using approved gas
leak detectors. Gas leak testing is performed as follows:
Therma Grow™ Greenhouse Heaters
Fire and Explosion Hazard
n Do not use open flame (matches, torches, candles,
etc.) in checking for gas leaks.
n Use only approved leak detectors.
n Failure to follow this warning can lead to fires or
explosions.
n Fires or explosions can lead to property damage,
personal injury or loss of life.
-- Check all pipe connections, hose connections, fittings
and adapters upstream of the gas control with ap-
proved gas leak detectors.
-- In the event a gas leak is detected, check the compo-
nents involved for cleanliness and proper application of
pipe compound before further tightening.
-- Fur thermore 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 connec-
tions, 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 applica-
tion 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
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.
14. This heater can be configured for use with either
L.P. gas vapor withdrawal or natural gas. Consult
the dataplate for the gas configuration of the specific
heater. Do not use the heater in an L.P. gas liquid
withdrawal system or application. If you are in doubt,
contact the L.B. White Co., LLC.
