Wood Add-On Furnaces

Wood add-on furnaces are designed to be added to existing oil furnaces as a backup heat source (Figure 13-14). Their construction details are identical to those of a standalone wood furnace.

Caution

Make sure the existing furnace can accept an add-on unit. Not all furnaces can do this.

There are two types of add-on installations: independent and parallel. The parallel installation uses the existing blower in addition to the blower on the wood burning furnace (Figure 13-15).
