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.

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.
