The Invincible Insert is made up of three main
parts. They are the mounting shell, the wings, and
the stove insert, fig. 1.
A unique feature of this unit is the fact that
the insert can be removed from the fireplace for
service without removing the mounting shell, the
wings or disconnecting the flue pipe.
Please note that the insert extends through the
rear of the mounting shell and this distance needs
to be considered when installing the shell. The
easiest place to see this is before you remove the
unit from the skid, fig.3.
Installing the Mounting Shell
Before installation, remove the damper and
any accessories from the fireplace. It is intended
that a four inch stainless steel flex pipe shall be
connected to the pipe on the rear of the mounting
shell and extend up through the damper opening.
The pipe shall be sealed at the damper opening
with a metal plate or packed with fiberglass.
Install brass trim on wings with hardware
provided. Bolt wings to shell with button head
bolts.
Place flex pipe up through damper opening
and seal around the pipe. The pipe should be able
to slide down over the flue on the shell, and sealed
with high temp silicone.
Place shell with wings attached into the
fireplace. Level the wings in all directions with
the leveling bolts in the base of the shell. After
leveling, tighten the two 1/2" threaded rods up
against the fireplace lintel, fig. 2. Do not over-
tighten.
