CHIMNEY INSTALLATION
3
Each double wall chimney section consists of an inner and outer flue
pipe. The two sections of chimney pipe are not attached to each
other, and therefore must be installed individually. As the flue sec‐
tions are assembled, the inner flue section will slip to the inside of
the section below. The outer section of pipe will slide over the
hemmed edge of the section below.
When installed properly, the chimney sections will “snap” into place,
securely locking the two pieces together. If the chimney is pulled up‐
ward it will not separate from the pipe below if it is properly locked.
Check both the inner and outer sections of chimney when assem‐
bling the flue. Screws are not necessary to keep the chimney sections
together.
10) STARTER ELBOW (INNER)
– Begin the chimney installation by
inserting the hemmed edge of the inner starter elbow
inside
the
collar of the Anchor Plate. The inner chimney pipe slips into the
inside of the Anchor Plate collar so that any soot buildup will fall
into the firebox.
Align the inner Starter Elbow so that it points directly back away
from the Firebox face. Secure the inner Starter Elbow to the An‐
chor Plate collar by using four #12 x

” self drilling hex head
screws.
11) STARTER COLLAR
– The Starter Collar is used to support the
outer chimney section, while the Anchor Plate collar supports the
inner chimney. Attach the legs of the Starter Collar to the Anchor
Plate with the supplied #12 x

CHIMNEY OFFSET
An offset and return elbow set is re‐
quired for installation. Each elbow
set will contain an offset (or starter)
elbow, and a return elbow. The re‐
turn elbow, which will be used last
(step 12), has straps attached to it
that are attached to the walls in or‐
der to support the chimney.
