ATTENTION:
LIQUEFIED PETROLEUM
(LP) PROPANE
Liquefied Petroleum (LP) propane gas is heavier than air;
therefore, it is imperative that your boiler is not installed in a
pit or similar location that will permit heavier than air gas to
collect.
Local Codes may require appliances fueled with LP gas be
provided with an alarm or an approved means of removing
unburned gases from the room. Check your local codes for this
requirement.
