general information
2.4 high effi ciency heating
The NZ3000H-1 is a high effi ciency appliance that may be operated as a standalone system, however, a blower is
recommended to further enhance the effi ciency of the appliance.
The NZ3000H-1 and its optional heat distribution systems cannot be connected to other duct systems. The
NZ3000H-1 must be ducted independently when these installation options are used.
2.4.1 hot air gravity vent system (NZ220)
!
WARNING
• All hot air gravity vents must be insulated.
May be used to distribute heat
to an adjoining room (located
either above, or beside the room
containing the appliance) by way
of vents, eliminating the need of
an additional blower. While this
system may be used in conjunction
with the optional blowers, it could
reduce the fl ow of hot air being
distributed to additional rooms. It
must be experimented with and
the dampers adjusted manually to
suit your requirements. This may
take a few attempts; thereafter
adjustments should no longer be
required as is normally experienced
with your central heating system
registers. No more than two hot air
gravity vents can be installed to an
appliance. Individual vent runs are
not to exceed 10 feet (3m).
