FOR L.P. (LIQUEFIED PETROLEUM) GAS, CORRECT THE TOTAL BTU/HR. BY MULTIPLYING IT BY 0.6.
THE ANSWER IS THE EQUIVALENT BTU ON THE ABOVE CHART.
IMPORTANT: The installation must conform with local codes or, in the absence of local codes:
G with the latest edition of the "National Fuel Gas Code," ANSI Z223.1/NFPA 54 in the U.S.A.,
with CSA-B149.1 or Natural Gas and Propane Installation Code in Canada,
G
and Australian Gas Association/Australian L.P. Gas Association requirements in Australia.
