3.7 INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION

WARNING: Before starting the installation, the masonry chimney must be inspected
by a qualified sweep.
The following requirements must be respected:
1. The chimney must be absolutely clear of any soot residue or creosote. Check for
cracks, loose or missing bricks that could inhibit correct installation of the liner.
2. The clearance to combustible must be a minimum of 1" between the outside of the
masonry and any wood framing or loose insulation.
3. The chimney must be built in accordance with the current building code.
4. No other appliance can be connected to the same chimney.
Installation:
The chimney must be relined with a stainless steel liner of the same diameter as the
outlet of the fireplace. For connection at 30° or 45° angle, a special connector must be
used to connect the liner to the insulated chimney. Verify availability and installation
instructions for this connector with the chimney manufacturer.
Follow these steps:
1. Position the fireplace in its
location. Temporarily install the
elbow on the top of the fireplace
and, using a level, mark with
an oval the location where the
flue liner will enter the masonry
chimney.
2. In the middle of the oval, drill a
hole in the masonry chimney at
45° or 30°.
3. Increase the size of the hole until
a 45° or 30° liner elbow can be
easily slipped through.
4. Slide the liner down from the top
of the masonry chimney until you
reach the hole level.
5. Slip through the hole a 45° or 30°
liner elbow and connect it to the
liner.
6. Add a small liner section to the liner elbow which will allow the liner to extend at
least 12" (measured at the top of the liner) from the masonry chimney.
7. Seal the opening around the liner with high temperature refractory cement.
8. Then, follow the chimney manufacturer's instructions to connect the extended liner
section to the special chimney connector.
