Ussc - Ashley 24AF Owner's Manual

Your furnace is designed to be added on to existing duct
work and operate either with or without another heat source
such as a gas furnace. The following diagrams illustrate
acceptable ways of ducting your furnace.
Clearance to Combustible Materials
Your Furnace has been tested to determine the SAFE clear-
ances to combustible material. The clearances are printed
on the label located on the back of the furnace. The chart
on this page also states these minimum clearances. Make
sure you follow these when choosing your furnace loca-
tion.
Any hot air plenum connection to a furnace must be con-
structed of metal.
NOTE: INSTALL ONLY ON A NON-COMBUSTIBLE FLOOR.
