May be used to distribute heat to an
adjoining room (located either above,
or beside the room containing the
appliance) by way of vents, eliminat-
ing the need of an additional blower.
While this system may be used in
conjuction with the optional blow-
ers, 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 adjust-
ments 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).
