OWNERS INSTRUCTIONS, DO NOT DESTROY
READ PRIOR TO INSTALLATION AND OPERATION
INSTRUCTIONS MUST REMAIN WITH EQUIPMENT
CAUTION: GREEN OR RESINOUS WOODS MUST NOT BE BURNED IN ANY DOMESTIC WOOD BURNING STOVE
BECAUSE OF THE POTENTIAL HAZARD OF CHIMNEY FIRES.
The Burning of such woods as pine, fir, etc. produces a tar-like substance known as creosote which can coat the
interior of the chimney and Draft Inducer. Stack temperature may become high enough to ignite the deposits and
cause a chimney fire.
Similarly, caution must be exercised when artificial or paper roll logs are burned because of the large volumes of flue
gas and smoke produced. If artificial logs must be used, burn only one or two at a time to determine whether or not
the smoke output exceeds your stove's venting capacity.
The Auto-Draft needs to pull adequate air through the stove to run properly. Make sure your stove has some type of air
shutter door or air intakes to satisfy draft.
The Auto-Draft requires a straight section of single wall stove pipe for installation. You must maintain an 18" clearance
from combustibles to the AD-1 housing. Refer to NFPA #211 for further information.
Allow for a 1 to 2 foot distance between the AD-1 and the stove when mounting. Temperature around the electrical box
and motor must not exceed 104
stove.
NOTE: The fan should run constantly if smoke is coming out of motor cooling hole during stove operation.
Failure to follow these guidelines could result in severe personal injury and equipment damage.
The Auto-Draft may be mounted on horizontal, vertical or inclined vent
pipes. Installation on horizontal vent pipes must be made on the
underside of the pipe to prevent excessive heat build up within the fan
housing. Using the enclosed template, drill (4) 7/32" holes for speed
nuts and cut a rectangular hole for the Auto-Draft, (See Diagram A). Insert
curved edge of the fan housing into the pipe in direction of airflow and
secure to pipe with screws, (See Diagram B).
CAUTION: Allow for a 1 to 2 foot distance between the Auto-Draft and
the stove when mounting. Speed control or motor damage may result
from heat if mounted too close to stove.
