ACCESSORIES

SIDE WALL VENT KIT (0170K00000S)

This side wall only vent kit #0170K00000S is to be used
with 2” - 3” vent systems. This kit is

NOT intended

for

use with single pipe (non-direct vent) installations.
The vent kit must terminate outside the structure and may
be installed with the intake and exhaust pipes located side-
by-side or with one pipe above the other.
See the section in this manual under "Vent Flue and Com-
bustion Air Pipe Terminations" for more information or
consult the Installation Instructions (IO-635).

The vent kit must terminate outside the structure and may
be installed with the intake and exhaust pipes located side-

LPLP03 LOW LP GAS PRESSURE SHUT-OFF KIT

Installation of the LPLP03 kit is recommended on every LP
converted furnace to protect the furnace against low LP
gas supply pressure. Low LP supply pressure can cause poor
combustion and carbon in the heat exchanger. The LPLP03
kit will open the electrical circuit to the gas valve in the
event of low supply pressure. The kit contains a pressure
switch, gas fittings and electrical harness to connect the
switch in series with the gas valve.

LPM-09 LP CONVERSION KIT

This furnace is factory equipped to operate on Natural Gas
but may be field converted to operate on LP gas. To con-
vert a DM97MC or DC97MC furnace to operate on LP gas,
the LPM-09 conversion kit must be used. The LPM-09 kit
contains a modulating gas valve ready for use with LP gas,
as well as a set of 1.25 mm orifices to replace the factory
installed natural gas orifices. Do not attempt to convert a
modulating furnace gas valve. Factory burners are suit-
able for both gases, L.P. and Natural. Burner replacement
is not required when the furnace is converted for use with
L.P. gas.

AFE18-60A DUAL FUEL ACCESSORY

When installing the modulating furnace with a heat pump,
the preferred installation would include a communicating
thermostat. A communicating thermostat provides control
of gas heat and heat pump operation and eliminates the
need for a separate dual fuel control. A legacy dual fuel
thermostat could also be used with 24 volt wiring to con-
trol the gas furnace and heat pump. If a communicating
thermostat or legacy dual fuel thermostat are not used,
the AFE18-60A kit must be added to provide control of the
equipment. This control is mounted indoors near the fur-
nace and provides terminals for thermostat, furnace, and
heat pump wiring. The AFE18-60A may be used with or
without a separate outdoor thermostat.

OT18-60A OUTDOOR THERMOSTAT

For use in a legacy dual fuel installation to lock-out the
heat pump at a selected temperature.

CFSB17, 21, 24 COUNTER FLOW BASE

The CFSB base must be used when installing a DC97MC
furnace in the vertical position on a combustible floor with-
out a coil under the furnace.
