1.3.3 Separated-Combustion Models SDH and SHH
Models SDH and SHH are designed and manufactured in accordance with the ANSI
definition of separated combustion. That definition reads, “Separated Combustion Sys-
tem Appliance: A system consisting of an appliance and a vent cap supplied by the
manufacturer, and (1) combustion air connections between the appliance and the out-
side atmosphere, and (2) flue gas connections between the appliance and vent cap,
of a type(s) specified by the manufacturer but supplied by the installer, constructed so
that, when installed in accordance with the manufacturer’s instructions, air for com-
bustion is obtained from the outside atmosphere and flue gases are discharged to the
outside atmosphere.”
Model SDH and SHH separated-combustion units are designed to separate air for
combustion and flue products from the environment of the building in which the unit is
installed. Separated-combustion appliances are recommended for use in dust laden
and some corrosive fume environments or in buildings with negative pressure (up
to .15” w.c.). As the definition states, all separated-combustion equipment must be
equipped with both combustion air and exhaust piping to the outdoors.
