3- Place the two small 2" x 4 3/8" (51 x 111mm) bricks up into the top front side
spaces below the stainless steel tube.
4- Place the baffle brick retainer up over the back duct and over the stainless steel
tube so that the angled rib is on the top. Move it to the middle under the ceramic
insulation.
5- Angle each of the two rear baffle bricks up to the top right or left and place them so
that they sit crosswise under the ceramic insulation, over the back duct, over the
side bricks, and over the baffle brick retainer. Push them toward the back and
make sure that the insulation over them is flat.
6- In the same way angle each of the two front baffle bricks up to the top front right or
left so that they sit crosswise under the ceramic insulation, over the stainless steel
tube, over the baffle brick retainer, and over the side bricks. Push them toward the
front.
7- Similarly, place the two middle baffle bricks crosswise between the front and rear
baffle bricks. Make sure that the insulation is flat over them. Push them toward the
back so there are no gaps between the bricks.
8- Reach up inside and lift the insulation up slightly while pushing the right, and then
the left, front baffle bricks toward the back.
9- Once all the bricks are in, make sure that the ceramic insulation is flat over and
flush with the front edge of the bricks, and sealed against the firebox wall along the
back and sides. Push all the baffle bricks toward the back and centre - do not allow
the bricks to sit on the angled rib of the baffle brick retainer.
10- Place the included steel insulation weight at the top back centre of the ceramic
insulation. This weight will prevent the insulation from being drawn toward the flue
hole, causing a possible blockage under extreme draft conditions. The metal plate
will be located inside the firebox when the appliance is packaged.
