LP and Natural gas have an odorant added to aid in detecting a gas leak. Some people 

may not physically be able to smell or recognize this odorant. If you are unsure or 

unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, 

such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or 

camouflage a gas leak.

DANGER!

LIqUEFIED PETROLEUM (LP    PROPANE OR BUTANE) 

AND NATURAL GAS MODELS

  Water heaters utilizing LP gas are 

different from natural gas models. A 

natural gas water heater will not function 

safely on LP gas and vice versa. 

  No attempt should ever be made to 

convert the water heater from natural 

gas to LP gas. To avoid possible 

equipment damage, personal injury or 

fire, do not connect the water heater to a 

fuel type not in accordance with the unit 

data plate. LP for LP units. Natural gas 

for natural gas units. These units are not 

certified for any other fuel type.

  LP appliances should not be installed 

below grade (for example, in a basement) 

if such installation is prohibited by 

federal, state and/or local laws, rules, 

regulations or customs.

  LP gas must be used with great caution. 

It is heavier than air and will collect first 

in lower areas making it hard to detect at 

nose level.

  Before attempting to light the water 

heater, make sure to look and smell for 

gas leaks. Use a soapy solution to check 

all gas fittings and connections. Bubbling 

at a connection indicates a leak that must 

be corrected. When smelling to detect a 

gas leak, be sure to sniff near the floor 

also.

  Gas detectors are recommended in LP 

& natural gas applications and their 

installation should be in accordance 

with the detector manufacturer’s 

recommendations and/or local laws, 

rules, regulations or customs.

  It is recommended that more than one 

method, such as soapy solution, gas 

detectors, etc., be used to detect leaks in 

gas applications.

!

DANGER: If a gas leak is present or 

suspected:

 

 Do  not 

attempt to find the cause 

yourself.

  

Do  not

 try to light any appliance.

  

Do  not

 touch any electrical switch.

  

Do  not

 use any phone in your building.

  Leave the house immediately and make 

sure your family and pets leave also.

  Leave the doors open for ventilation 

and contact the gas supplier, a qualified 

service agency or the fire department.

  Stay away from the house (or building) 

until the service call has been made, the 

leak is corrected and a qualified agency 

has determined the area to be safe.
