INSTALLATION INSTRUCTIONS FOR MASONRY APPLICATION
WARNING: Before starting the installation, the masonry chimney must
be inspected by a qualified chimney 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.
5. The clearances to combustible for these fireplace connectors are 2”
on the side and bottom and 16” at the top.
6. The connector parts are not necessary if the connection between the
insulated length and the stainless steel liner is done within the masonry
chimney.
Installation:
The chimney must be relined with a stainless steel liner model Tubinox
®
*
or Projet
®
SS
*
of the same diameter as the outlet of the fireplace. If a
stainless steel liner is used, see note below**.
For connection at a 30º angle, a special connector (BISUMA30
*
) must be
used to connect the liner to the insulated chimney.
* IMPORTANT NOTE - The use of a 45º connector (BISUMA
*
) is ap-
proved for use in Canada ONLY. Installations in the USA must use the
30º connector (BISUMA30
*
).
**
Alternate brand rigid stainless liner or stainless flex may be substituted but
must be listed to UL-1777 for US application and ULC-S635 for existing
masonry or ULC-S640M for new masonry applications in Canada. The steel
rigid or flex liner must be rated at 2100º F (1100º C).
Follow these steps:
1. Position the fireplace in its location. Temporarily install the ASHT+
*
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 30º.
3. Increase the size of the hole until a 30º Tubinox
*
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 30º 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. The next steps must be done in the following order:
See typical installation illustrated below.
A. Select the ASHT+
*
length that will fit between the elbow and the liner
so that it will slide at least 2” over the liner section (You may need to
cut the liner for a better fit).
B. Take that section and the BISUMA30
*
cover and slide it over the liner.
Make sure you have enough opening to be able to install the ASHT+
*
elbow without difficulty.
C. Install the 30º elbow on the fireplace.
D. Slide the length section back down on the elbow and twist lock the
two together.
E. Pull the cover down over the length and install the insulation pad over
the liner; be careful to cover the liner completely.
F. Slide back the cover over the insulation and fix it in place using the 3
metal screws supplied.
