1. Connect Y-terminal in furnace as shown for proper blower operation.
2. Some thermostats require a "C" terminal connection as shown.
3. If any of the original wire, as supplied, must be replaced, use
same type or equivalent wire.
When an existing furnace is removed or replaced in a venting
system, the venting system may not be properly sized to vent the
attached appliances. An improperly sized Category I venting
system could cause the formation of condensate in the furnace and
vent, leakage of condensate and combustion products, and spillage
of combustion products into the living space, etc.
