INSTALLATION INSTRUCTIONS

Inspect the fireplace according to the safety information and fireplace requirements

and have it cleaned and/or upgraded as necessary.

2.

If the installation of the unit renders the existing damper control inaccessible, it will

be necessary to either secure the damper wide open or remove it entirely. An inaccessible
damper which may fall shut later could cause smoke to enter the room. This would be a
nuisance as well as a potential health hazard.

3.

POSITIVE CONNECTOR INSTALLATION:

NOTE: A positive flue connector may provide acceptable performance, however, we
recommend the use of a chimney liner to ensure satisfactory performance. Slip
connectors for continuous liners should be installed similarly.

A.

Referring to the table and Figure 5, pick a location for the positive connector plate.
It will be easiest to install the plate so that the hole for the flue is somewhere in
between the extreme positions, and to use the adjustability of the faceplate to take
up any inaccuracies in the fit. Alternatively, the plate itself can be moved up and
back by using a 6" (152mm) extension directly on the flue.

If you are securing the connector with a screw, the hole in the flue collar and the
connector pipe should be drilled prior to final installation.

Cut the plate to size and/or bend the edges over so that it will fit the cavity. The
plate can then be secured to the throat of the fireplace using steel or masonry
fasteners depending on the material. Locate the plate and drill through it into the
backing material. Install the fasteners.

Install the flat self-adhesive gasket around the inside of the 6" diameter (152mm)
hole in the plate. Put the handle through the two holes in the throat connector (see
Figure 4). Install the female end of the throat connector up through the hole in the
plate so that it is held in position by friction, ready to be pulled down later.

Positively seal any leaks between the plate and the brickwork. Any leaks will draw
air into the fire, which will affect performance.
