STEP 5 FIREBACK & SECONDARY AIR TUBE INSTALLATION CONTINUED
Lay 24” screen, supplied with materials, on the
top rib as pictured (FIG. 11). Press the screen
into the cement so the extension of the “T” fits
between the top ribs of the Back Plate and the
Fireback. Add more cement to make a tight
seal. You may use a putty knife to smooth the
cement along the top of the Secondary Air Tube.
Run the end of a broom handle or a 1/2” x 1” x
36” piece of wood into the secondary air
channel to smooth the layer of cement and clear
the channel.
Set the Upper Fireback in place, making sure all
the tabs overlap those on the Lower Fireback
(FIG. 12). You do not need to cement between
the upper and lower fireback.
Tap the lower right corner of the Upper
Fireback to persuade it into the channel on the
Baffle.
If the firebacks are separated, grind down the
interlocking tabs so the Upper Fireback sits
down completely on the top of the Lower
Fireback.
Set the Smokeshelf in place on the Back Plate
and along the Upper Fireback. The cutout
corner of the Smokeshelf should be placed in
the back right corner, where the Right Baffle
meets the Back Plate (FIG. 13). Do not use
cement.
Install the damper so that the Right Damper
Pin is in the hole in the Baffle (FIG. 13).
