Thermostat Requirements
DM96SE and DC96SE model furnaces require a single
stage heating thermostat for operation. It is recommended
that a high quality thermostat with a "C" terminal is used to
operate the furnace.
GAS SUPPLY AND PIPING
The furnace rating plate includes the approved furnace gas
input rating and gas types. The furnace must be equipped
to operate on the type of gas applied. This includes any
conversion kits required for alternate fuels and/or high
altitude.
CAUTION
To prevent unreliable operation or equipment damage, the
inlet gas supply pressure must be as specified on the unit
rating plate with all other household gas fired appliances
operating.
Inlet gas supply pressures must be maintained within the
ranges specified below. The supply pressure must be
constant and available with all other household gas fired
appliances operating. The minimum gas supply pressure
must be maintained to prevent unreliable ignition. The
maximum must not be exceeded to prevent unit overfiring.
