Assembly Instructions - 36 C
Step 3: Continue assembly of the second, third and fourth
courses of the firebox side wall and back wall. Apply mortar to
the top of each layer of wall components, set the next course
above into place. Be sure to mortar all vertical joints of the side
wall to back wall connection when setting each component to
its mate.
Look for some mortar to squeeze out along the joints
of all contact surfaces as a sign that the joint is thoroughly
sealed with the approved mortar.
Step 4: When all of the firebox wall components are set, check
the top surface of the firebox for level.
If necessary, adjust the top surface of the box assembly for level
by inserting a shim between the lowest wall component and the
top surface of the base plate.
Any gap created under the wall components during the
Shim leveling process must be filled with mortar to full bearing
against the base plate.
Step 5: Make sure that the firebox assembly has been set level
and square. Adjust as required while the mortar is still wet.
Make a final inspection of all contact joints in the fire
-
box assembly to be sure they are properly sealed. Fill any and
all gaps in the assembly, as necessary, with the approved mortar.
Step 6: Take the Catalytic assembly out of the box and verify all
components are in tact and Yellow EPA hangtag is attached to
the filter. The Catalytic kit should contain a Catalytic
Combustor, 6” diameter flue pipe (24” tall) and two (2) metal
angle support brackets.
Step 7: Insert support brackets so that the largest angled portion
slides into the side wall cavity toard the rear of the firebox. The
smaller angles should be facing upward toward the inside of the
firebox.
Step 8: Center the Catalytic Combustor in the firebox and rest
it on top of the support brackets making sure that the filter is
equally settled on the brackets. The filter should be set toward
the rear of the firebox.
Step 9: Attach the twenty four inch (24”) flue pipe on the appro
-
priate fitting making sure there are no obstructions above it.
Step 10: Set the back smoke dome component across the rear
side walls in a bed of mortar and flush with the back face of the
back wall.
Set the front smoke dome component in mortar across
the front side walls flush with the front of the sidewalls.
Step 11: Position the smoke dome’s sloping sidewalls at each
end of the smoke dome components.
The sloping sidewalls fit in between the front and rear
smoke dome components and also fit into the haunches at the
ends of the front and rear smoke dome components. Mortar all
contact surfaces thoroughly.
