1. Do not attempt to install, repair, or service this heater

or the gas supply line unless you have continuing

expert training and knowledge of gas heaters.  

Qualifications for service and installation of this

equipment are as follows:

a. To be a qualified gas heater service person, you

must have sufficient training and experience to

handle all aspects of gas-fired heater installation,

service and repair.  This includes the task of

installation, troubleshooting, replacement of

defective parts and testing of the heater.  You must

be able to place the heater into a continuing safe

and normal operating condition.  You must

completely familiarize yourself with each model

heater by reading and complying with the safety

instructions, labels, Owner’s Manual, etc., that is

provided with each heater.

b. To be a qualified gas installation person, you must

have sufficient training and experience to handle

all aspects of installing, repairing and altering gas

lines, including selecting and installing the proper

equipment, and selecting proper pipe and tank size

to be used.  This must be done in accordance with

all local, state and national codes as well as the

manufacturer’s requirements.

2. We cannot anticipate every use which may be made of

our heaters.  Check with your local fire safety authority

if you have questions about applications.

3. All installations and applications of L.B. White heaters

must meet all relevant local, state and national codes.

Included are propane gas, natural gas, electrical, and

safety codes.  Your local fuel gas supplier, a local

licensed electrician, the local fire department or

similar government agencies, or your insurance agent

can help you determine code requirements.

Also refer to:

-- ANSI/NFPA 58, latest edition, Standard for

Storage and Handling of Liquefied Petroleum

Gas and/or:

-- ANSI Z223.1/NFPA 54, National Fuel Gas Code

-- ANSI/NFPA 70, National Electrical Code.

4. Do not move, handle, or service heater while in

operation or connected to a power or fuel supply.

5. For safety, never operate this heater with any of its

safety devices that have been bypassed.  Do not

operate this heater unless all of these features are

fully functioning.

6. Do not operate the heater with case removed.

7. Do not locate fuel gas containers or fuel supply hoses

anywhere near the discharge outlet of the heater.

8. Do not block air intakes or discharge outlets of the

heater.  Doing so may cause improper combustion or

damage to heater components leading to property

damage or animal loss.

9. The hose assembly shall be visually inspected on an

annual basis.  If it is evident there is excessive

abrasion or wear, or if the hose is cut, it must be

replaced prior to the heater being put into operation.

The hose assembly shall be protected from animals,

building materials, and contact with hot surfaces

during use.  The hose assembly shall be that specified

by the manufacturer.  See parts list.

10. Check for gas leaks and proper function upon heater

installation, periodically, and when relocating the

heater, its gas supply, or gas supply line.

11. This heater should be inspected for proper operation

by a qualified service person before building

repopulation, each use, and at least annually.

12. Always turn off the gas supply to the heater when the

heater is not in use.

13. This heater is wired for a three-wire 24 Volt D.C.

electrical system.  There is a positive lead, negative

lead, and a ground lead.  The heater must be properly

connected into a grounded electrical supply using the

ground lead in the power cord.

14. If gas flow is interrupted and flame goes out, do not

relight the heater until you are sure that all gas that

may have accumulated has cleared away.  In any

event, do not relight the heater for at least 5 minutes.

15. In a hanging type installation, rigid pipe or copper

tubing coupled directly to the heater may cause gas

leaks during movement, and therefore must not be

used.  Use only gas hose assemblies that are rated

and approved for propane gas and natural gas in a

hanging type of installation.

16. When hanging the heater, use only approved gas hose

or approved flexible connectors which are rated for use

with propane or natural gas.

17. If your heater utilizes propane vapor, the minimum

propane gas supply cylinder size should be a 100

pound cylinder.  When using a cylinder supply system,

it should be arranged to provide vapor withdrawal from

operating cylinder.

18. When the heater is to be stored indoors, the

connection between the propane gas supply

cylinder(s) and the heater must be disconnected and

the cylinder(s) removed from the heater and stored in

accordance with the Standard for the Storage and

Handling of Liquefied Petroleum Gases, ANSI/NFPA

58.

19. Propane gas supply cylinders have left-handed

threads.  Always use a wrench to make the connection

to remove the P.O.L. fitting.  Do not use a pliers.
