IMPORTANT: For L.P. 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:
with the latest edition of the "National Fuel Gas Code," ANSI Z223.1/NFPA 54 in the U.S.A.,
G
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.
