INSTALLATION INSTRUCTIONS FOR

MASONRY APPLICATIONS

WARNING
Before starting the installation,
the masonry chimney must be
inspected by a qualified chimney
sweep.
The following requirements must be met:
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 the
BISPMA30 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.
For connection at a 30º angle, a special con-
nector (BISPMA30) must be used to connect
the liner to the insulated chimney.
* IMPORTANT NOTE - The use of a 45º connec-
tor (BISPMA) is approved for use in Canada
ONLY. Installations in the USA must use the
30º connector (BISPMA30).
See Figure 31 for typical installation.
Follow these steps:
1- Position the fireplace in its location. Tem-
porarily 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 45° or 30°.

Note: 45° offsets allowed in Canada only.
3- Increase the size of the hole until a 45º
or 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 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- The next steps must be done in the fol-
lowing order :

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 45° or 30° elbow on the fire-
place.
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.
