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 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 unit’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.

5. 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.

6. 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 malfunction 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.  

7. Any heater or appliance connected to a piping system

must have an accessible, approved manual shut off 

valve installed within six feet (6 ft.) of the appliance it

serves.  

8. 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.  

-- 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.

9. A qualified service agency must check for proper

operating gas pressure upon installation of the heater.

WARNING

Fire oor eexplosion hhazard.

Can ccause pproperty ddamage, ssevere iinjury oor ddeath.

1. Disconnect 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.
