AND COMBUSTION AIR
This furnace must be connected to a plastic venting system
adequate to remove flue gases to the outside atmosphere.
It must be vented in accordance with these instructions and
local building codes.
The furnaces covered by this manual are design-certified
as Category IV appliances. Category IV appliances operate
with a positive vent static pressure and with a flue gas
temperature that will produce significant condensate in the
vent. The vent system for this furnace must be installed so
as to prevent leakage of flue gases into the building. This
furnace may be installed using either direct venting or non-
direct venting.


          WARNING: Do not connect this furnace to a vent         Figure 2. Vent Connection to Furnace.

     See Figure 2. As shipped, furnace is setup for venting
     through the left side.         Right side venting is
     accomplished by rotating flue outlet fitting and adding a
     street elbow to the drain fitting. Street elbow and
     instructions are supplied in the furnace parts package.
