Furnace with dual use inducer motor

A method for heating an enclosure comprising the steps of:

• providing a furnace adapted to heat the enclosure, said furnace having a two speed inducer motor with a common terminal, a low speed terminal and a high speed terminal;
• venting combustion byproducts from the furnace through a vent pipe in one of two orientations, a first orientation in which said vent pipe is substantially vertical and a second orientation in which said vent pipe is substantially horizontal;
• providing electrical power to said common terminal and only to said low speed terminal at all times when said vent pipe is in said first orientation and to said common terminal and only to said high speed terminal at all times when said vent pipe is in said second orientation such that the inducer motor operates at all times at one speed, with the other speed not being used.
