Installation
This furnace is manufactured with 2” CPVC vent & intake
couplings. Use transition cement to connect PVC or ABS
pipe to these fittings. For furnaces requiring installation
of 3” pipe, the transition from 2” to 3” should be made as
close to the furnace as possible, and only when the piping
is sloped enough to prevent condensation from collecting.
This furnace must not be connected to Type B, BW, or
L vent or vent connector, and must not be vented into
masonry chimney. A masonry chimney may be used as
a chase or passage way for approved venting materials
providing the masonry chimney is not also being used to
vent products of combustion. Never common vent this
appliance with another appliance. Never use a vent which
is used by a solid fuel appliance.
Piping may run vertically or horizontally and must be
adequately supported to prevent strain on joints, sagging,
separation, and detachment from the furnace. Horizontal
runs of piping must be supported every three to five
feet. Condensation within the furnace secondary heat
exchanger and in the vent pipe is a normal occurrence.
Vent pipe must be installed to maintain a minimum 1/4 inch
per foot downward slope toward the furnace to return
condensate to the furnace’s drain system. Condensation
may also occur in the intake pipe. This commonly takes
place during the summer months when humid air enters
an intake pipe that runs through a cool basement or other
conditioned space. Refer to intake pipe options for using
the RF000142 kit and managing condensation.
WARNING
To avoid bodily injury, fire or explosion, solvent cements
must be kept away from all ignition sources (i.e. sparks,
open flames, and excessive heat) as they are combustible
liquids. Avoid breathing cement vapors or contact with skin
and/or eyes.
