less expensive than a complete section of cast iron grate, and the brick

will hold more heat and make your wood last longer as it burns.

SECTION V: HOT AIR HOOK-UP (See Fig. 3)

NOTE: The warm air supply-duct system should be constructed of

materials with a minimum temperature rating of 250 deg. F. Also, the

plenums installed to the furnaces are to be constructed of metal.

NOTE: The hot air supply outlet of this supplementary furnace should not

be connected to the cold-air return inlet of the central furnace, since a

possibility exists that components of the central furnace could overheat in

this situation and cause the central furnace to operate other than as

intended.

Before making the hot air hook-up, you should have your unit positioned

as close to the flue connector as possible and have your flue pipe

installed. If this has not been done, please do so before continuing.

Located on the top, near the front of the unit is an eight-inch opening for

the mounting of the flue collar. When mounting this part, be absolutely

sure it is fastened securely to the opening, as this will be the hot air exit.

Thirty gauge or thicker pipe should be used from here to the hot air trunk

line of your existing hot air system. Using the least possible amount of

pipe will help the heat transfer to your duct system. Cut an eight-inch

diameter hole in the main trunk line of the furnace duct, which is usually

located on the top of the central furnace. Place the 8” (8 inch) pipe from

the wood furnace into the hole (see Figure 3) and seal the connection with

duct tape. Thirty gauge or thicker black pipe should be used for the first

two feet and then thirty gauge or thicker galvanized pipe can be used to

connect to the existing furnace duct. Sheet metal screws should be used

to secure each joint of pipe, and an aluminum heat resistant tape can be

wrapped around each joint to give an airtight seal. See Figure 3 for more

information, including the use of a Backflow Damper. Follow the

manufacturer’s instructions when installing a Backflow Damper.

SECTION VI: BLOWER AND THERMOSTAT INSTALLATION

A. Blower Installation

The BM-1376 blower will be mounted to the opening that is located at the

bottom on the rear of the stove. The blower will simply mount to the

opening with the five screws that are installed on the unit.

The heat circulation blower on this furnace requires periodic lubrication; this lubrication should

be performed no less than every three months of normal operation. To properly lubricate the

blower, use an eye dropper or similar dispensing device to drip 5-7 droplets of SAE 20 oil into

the oil

ort on the side of the blower motor.
