Clearance To Combustibles - USSC Ashley 30A 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
clearances 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 mini-
mum clearances. Make sure you follow these when
choosing your furnace location.
Any hot air plenum connection to a furnace must be
constructed of metal.
NOTE: INSTALL ONLY ON A NON-COMBUSTIBLE FLOOR.
