8. Remove the yellow low-speed wire from the blower motor (this should be the

selected low-speed in the furnace wiring box), and connect it to one side of the

normally closed contacts (relay spade #4).

9. Connect the yellow wire (item 5) to the low-speed connection on the blower

motor, and the other end of the wire on to the other side of the normally closed

contacts (relay spade #5).

10. Turn ON POWER to the oil furnace and wood furnace. Check relay operation.

2.7 DUCT CONNECTION (Fig S101-5, Fig S101-1)

See figure S101-12 for Approved Furnace Ductwork Configurations.

See figure S101-13 for Prohibited Furnace Ductwork Configurations.

Minimum cross-sectional area of ductwork from furnace should be approximately 180

sq. in. with equal or larger size for return air.

The furnace must not be installed as a gravity system as the controls are not designed

for this type of operation.

The dimensions and locations of permissible openings in casings for ducts, blower, or

emergency air are clearly identified on the furnace or on specific templates enclosed in

the firebox.

DO NOT use duct elbows having an inside radius of less than 6 in (155mm). Use only

16 x 20 in. duct “S” type interconnection for this furnace.

Make or enlarge the openings in the wood furnace casing exactly as identified for add-

on connection and on the appropriate side, trim the furnace insulation flush with cut

opening. Fasten edges of insulation securely with metal straps or bend tabs of duct

starting collar over insulation edge to hold it in place.

Make all duct connections for the “S” type interconnection (See Fig S101-5).

CAUTION: The DB-101-ADD is NOT certified for installations using a divider in the

plenum of the oil furnace.

An ADD-ON unit must only be connected to a furnace, duct system and

chimney, which are in good operating condition.

DO NOT relocate any of the safety controls in the original furnace

installation.

Operate the oil-fired unit periodically to ensure that it will operate

satisfactorily when needed.

DO NOT connect to duct work so that a reverse flow is possible.
