Special Precautions for LP Gas
Under the same environmental conditions, liquid propane
(LP) gas is more dense or heavier than air and will more
readily collect or pool in enclosed areas if adequate
ventilation is not provided. It is not recommended to
install LP gas heaters in enclosed areas such as pits.
Locate heaters a safe distance from LP gas cylinders and
fi lling equipment. Consult the National Fuel Gas Code
(NFPA
®
54/ANSI
®
Z223.1, latest edition), the Liquefi ed
Petroleum Gas Code (NFPA 58, latest edition), the
Natural Gas and Propane Installation Code in Canada
(CAN/CSA B149.1, latest edition), and any other local
codes and fi re protection authorities about specifi c
installation restrictions in your area.
For ALL installations the combustion air openings
requirements and NFPA54 / ANSI Z223.1 MUST be
followed for safe and proper operation.
