For ECV boiler with Honeywell
intermittent pilot (spark) ignition, the
main burner for mounting the
Q3451A pilot assembly contains one
less group of main burner ports (5). If
theburnersaredisassembledor
replaced for any reason, they must be
reassembled as shown in Figs. 14a,
14b, 14c, 14d. If the Q3451A pilot
assembly is accidentally assembled
into a 6 port burner, it will be
exposed to t he flames from the first
row of ports and will overheat and
become defective. Defective pilot will
prevent boiler from operating, which
could cause property damage from
freezing.
