GeneralOperation
Models covered by this manual come with a new 4-wire
communicating PCB. When paired with a compatible
communicatingindoorunitanda CTK0*AA communicating
thermostat,thesemodelscansupport4-wirecommunication
protocolandprovidemoretroubleshootinginformation.These
models are also backward compatible with the non-
communicatingthermostat wiring.
The *CVM96 and *MVM96 furnaces are equipped with an
electronic ignition device used to light the burners and an
induceddraft blower to exhaust combustionproducts.
Aninterlockswitchprevents furnace operation if theblower
door is not in place. Keep the blower access door in place
exceptforinspection and maintenance.
This furnace is also equipped with a self-diagnosing elec-
tronic control module. In the event a furnace component is
notoperating properly, the controlmoduleLED will flashon
and off in a factory-programmed sequence, depending on
theproblemencountered. This light canbe viewedthrough
theobservationwindowin the blower access door.Refer to
theTroubleshootingChartforfurther explanation oftheLED
codesandAbnormal Operation - Integrated Ignition Control
section in the Service Instructions for an explanation of the
possibleproblem.
Theratedheatingcapacityof the furnace should be greater
thanor equal to thetotalheat loss ofthe areatobe heated.
The total heat loss should be calculated by an approved
methodorinaccordance with “ASHRAE Guide” or “Manual
J-LoadCalculations” published by theAirConditioningCon-
tractors of America.

LocationConsiderations
• The furnace should be as centralized as is practical
with respect to the air distribution system.
• Donotinstallthefurnacedirectly on carpeting, tile, or
combustiblematerialotherthanwood flooring.
• When suspending the furnace from rafters or joists,
use 3/8" threaded rod and 2” x 2” x 3/8” angle as
shownintheInstallationand ServiceInstructions.The
length of the rod will depend on the application and
clearancenecessary.
• When installed in a residential garage, the furnace
mustbe positioned so theburnersandignitionsource
are located not less than 18 inches (457 mm) above
the floor and protected from physical damage by ve-
hicles.
