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 level and properly positioned

before use. Observe and obey all minimum safe

distances of the heater to the nearest combustible

materials. Safe distances are given on the heater

dataplate and on page 4 of this manual.

3. This heater may be installed either indoors or

outdoors. For outdoor installations, only the following

air distribution devices may be used:

-- 18 in. Dia. x 12 ft. Duct: Part # 22841

-- End Diffuser: Part # 23054

4. The heater’s gas pressure regulator (with pressure

relief valve) must be protected from adverse weather

conditions (rain, ice, snow) as well as from building

materials (tar, concrete, plaster, etc.) which can affect

safe operation and could result in property damage or

injury.

5. Heaters used in the vicinity of combustible tarpaulins,

canvas, plastics, wind barriers, or similar coverings

shall be located at least 10 feet from the coverings.

The coverings shall be securely fastened to prevent

ignition or upsetting of the heater due to wind action

on the covering or other material.

6. 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.

-- 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.

7. A qualified service agency must check for proper

operating gas pressure upon installation of the

heater.

8. Light according to instructions on heater or within

owner's manual.

9. Make sure the heater has the proper gas regulator 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.

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.

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 normal hand

pressure the gas control valve should be replaced by

a qualified service technician. Force or attempted
