Optional Equiptment
11DIKL Draft Inducer Kit w/ Limit Swich
This optional kit allows your furnace to be thermostati-
cally controlled and gives the option to change the on/off
times of the distribution blower(s).
UFB908 Universal Filter Box
When installing ANY warm air furnace, proper installation
is the key and required for getting the most efficiency and
longest life out of your unit. Failure to install your furnace
as outlined from the manufacturer, often will result in in-
adequate heating and problems associated with drafting.
U. S. Stove Co. offers the UFB908, a universal filter box
that mounts to the rear of the unit that your return air duct
work will attach to. It uses a standard 16 x 20 x 1 filter
(NOT INCLUDED) to reduce the amount of dust particles
from being transfered thru you duct work system.
11DIKL
DR-6 Barometric Damper Regulator
In the unlikely event that your furnace "overfires" (a con-
dition evidenced by elbows, stove pipes, and connectors
glowing red in appearance or otherwise discoloring),
then your installation is subject to excessive draft cre-
ated by either a chimney too tall or too great in diameter
in conjunction with its height, or some other factor of an
indeterminate cause. In this event, you should install a
barometric draft regulator. Such installation will preclude
any over-firing and/or any hazardous consequences of
potential overfiring.
Barometric draft regulators are generally available where
you purchased your stove or may be ordered directly
from United States Stove Company at a nominal charge.
