ATTENTION -- CRITICAL POINTS TO REMEMBER!

Propane gas and natural gas have a distinctive odor.

Learn to recognize these odors.  (Reference “Fuel Gas

Odor” and “Odor Fading” sections above.

If you have not been properly trained in repair and service

of propane gas and natural gas fueled heaters, then do

not attempt to light heater, perform service or repairs, or

make any adjustments to the heater on propane gas or

natural gas fuel system.

Even if you are not properly trained in the service and

repair of the heater, ALWAYS be consciously aware of the

odors of propane gas and natural gas.

A periodic “sniff test” around the heater or at the

heater’s joints; i.e. hose, connections, etc., is a good

safety practice under any conditions.  If you smell even a

small amount of gas, CONTACT YOUR FUEL GAS

SUPPLIER IMMEDIATELY.  DO NOT WAIT!

THAT’S  YYOUR  S

SIGNAL  TTO  G

GO  IINTO  IIMMEDIATE  AACTION!

Do not take any action that could ignite the fuel gas.  Do

not operate any electrical switches.  Do not pull any

power supply or extension cords.  Do not light matches

or any other source of flame.  Do not use your telephone.

Get everyone out of the building and away from the area

immediately.

Close all propane gas tank or cylinder fuel supply valves,

or the main fuel supply valve located at the meter if you

use natural gas.

Propane gas is heavier than air and may settle in low

areas.  When you have reason to suspect a propane

leak, keep out of all low areas.  

Natural gas is lighter than air and can collect around

rafters or ceilings.

Use your neighbor’s phone and call your fuel gas 

supplier and your fire department.  Do not re-enter the

building or area.

Stay out of the building and away from the area until

declared safe by the firefighters and your fuel gas 

supplier.

FINALLY,  let the fuel gas service person and the

firefighters check for escaped gas.  Have them air out

the building and area before you return.  Properly trained

service people must repair the leak, check for further

leakages, and then relight the appliance for you.

WARNING

Do not use this heater for heating human living quarters.

Do not use in unventilated areas.

The flow of combustion and ventilation air must not be

obstructed.

Proper ventilation air must be provided to support the

combustion air requirements of the heater being used.

Refer to the specification section of the heater’s Owner’s

Manual, heater dataplate, or contact the L.B. White 

Company to determine combustion air ventilation

requirements of the heater.

Lack of proper ventilation air will lead to improper

combustion.

Improper combustion can lead to carbon monoxide

poisoning in humans leading to serious injury or death.

Symptoms of carbon monoxide poisoning can include

headaches, dizziness and difficulty in breathing.

Symptoms of improper combustion affecting livestock

can be disease, lower feed conversion, or death.

Learn to recognize the odor of propane gas and natural

gas.  Local propane gas dealers and your local natural

gas supplier (utility) will be more than happy to give you

a “scratch and sniff” pamphlet.  Use it to become

familiar with the fuel gas odor.  

Smoking can decrease your ability to smell.  Being

around an odor for a period of time can affect your

sensitivity to that particular odor.  Odors present in

animal confinement buildings can mask fuel gas odor.

circumstances.

If there is an underground leak, the movement of gas

through the soil can filter the odorant.  

Propane gas odor may differ in intensity at different

levels.  Since propane gas is heavier than air, there may

be more odor at lower levels.

Always  bbe  ssensitive  tto  tthe  sslightest  ggas  oodor. If you

continue to detect any gas odor, no matter how small,

treat it as a serious leak.  Immediately go into action as

discussed previously.
