The wall bracket is only required for the WR 325 K … when mounted directly to combustible construction. The WR
400 K… T2 may be mounted directly to combustible construction.
** The high altitude ratings listed are Canadian Gas Association high altitude ratings and are only valid in Canada. In the
U.S., the National Fuel Gas Code, ANSI Z223.1/NFPA 54, recommends for high altitude installations above 2,000 feet,
that the input rate be reduced 4% for each 1,000 feet above sea level. – See page 8.
