PRODUCT DESIGN
CIRCULATING AIR AND FILTERS
DUCTWORK - AIR FLOW
Duct systems and register sizes must be properly designed
for the C.F.M. and external static pressure rating of the fur-
nace. Ductwork should be designed in accordance with the
recommended methods of "Air Conditioning Contractors of
America" manual D.
A duct system should be installed in accordance with Stan-
dards of the National Board of Fire Underwriters for the In-
stallation of Air Conditioning, Warm Air Heating and Venti-
lating Systems, Pamphlets No. 90A and 90B.
A return air filter is not supplied with the furnace. The in-
staller must supply a means of filtering all of the return air.
Filter(s) shall comply with UL900 or CAN/ULC-S111 Stan-
dards. If the furnace is installed without filters, the warranty
will be voided.
The following two charts show the bottom and side return
filter sizes available for each size furnace. Larger sizes are
also acceptable.
