Fixed Speed high Efficiency Blower Kits on Gas Furnace Applications
This addendum is a supplement to the unit Installation Instruction concerning twinning of the furnaces.
A furnace equipped with the Fixed Speed High Efficiency Blower Kit is capable of being twinned to another furnace
of the same model, provided that the other furnace is also equipped with the Fixed Speed High Efficiency Blower.
The thermostat wires and the 1/4 inch quick-connect terminals marked “TWIN” on the control boards must be con-
nected together for twinning. The fuses must remain installed on each board. Twinned furnaces must be properly
grounded according to local codes.
