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:

QUALIFICATIONS FOR 

SERVICING AND INSTALLATION:

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

must have been trained in gas-fired heater

ser vicing, repair and also have suf ficient

experience to allow you to troubleshoot, replace

defective parts, and test heaters in order to get

them into a continuing safe and normal operation

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 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. All installations or applications of L. B. White Co.,

Inc.’s radiant heater and associated zone control

panel should meet the requirements of local, state

and national L.P. gas and natural gas, electrical and

safety codes.  Your gas supplier, local licensed

electrician, local fire department and government

agencies can help you determine these requirements.

In the absence of local codes, comply with the

following:

--  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.

3. If at any time you notice something unusual about the

operation of your heater such as gas odor,

overheating, flames other than in the combustion

cone area, etc., evacuate the area immediately and

call your fire department and your gas service

agency.  Get assurances from the fire department

that the area is free of gas before you attempt to

relight the heater.  

4. The components on the heater that call for hand

operation should work with hand pressure only.  If

more force is required, have a qualified gas heater

service agency replace the complete part.  Do not

attempt to repair.

5. This heater is intended for the heating of livestock in

agricultural animal confinement buildings only.  The

heater shall only be mounted inside the animal

confinement building.  It shall not be used for outside

heating applications.

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

anywhere within the heating zone of the heater.

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

heater.  Doing so may cause improper combustion or

damage to the heater components leading to

property damage or animal loss.

8. Do not move, handle, or service the heater while in

operation or connected to fuel supply.

9. The hose assembly providing fuel to the heater must

be inspected on a regular basis.  This should be done

at least once a year, or when the building is cleaned

out.  If it is evident there is excessive abrasion or

wear, or if the hose is cut, it must be replaced prior to

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

installation, before building repopulation and when

relocating.  

11. If the gas flow is interrupted and the burner flame is

extinguished, immediately shut off the gas.  Do not

relight the heater until you are sure that all of the gas

that may have accumulated through the heater has

cleared away.  Do not relight the heater until at least

five minutes have passed.

12. If the heater is to be relocated, make sure that all gas

connections are capped and the gas supply is shut

off.  All connection points must be leak checked after

disconnection and after reconnection.
