plumbers strap is required for every 4-foot interval
between elbows to support the load
(Figure 54)
.
Attach the upper elbow to bring the chimney back
to vertical. See
TABLE 2
and
Figure 55
for offset
combinations – 2 offsets (4 elbows) maximum.

Attach the Flashing to the top of the chase
cover, sealing with a non-hardening waterproof
sealant. Secure in place with screws or rivets

Termination:
NFPA 211, “Standard for
Chimneys, Fireplaces, Vents, and Solid Fuel-
Burning Appliances,” states that chimneys shall
extend at least three feet above the highest point
where it passes through the roof of a building,
and at least two feet higher than any portion of a
building within ten feet
(Figure 60)
.
If the horizontal distance from the chimney edge to
the peak of the roof is greater than 10', a chimney
height reference point is established on the roof
surface 10' horizontally from the chimney edge.
The top of the chimney (point where exhaust
gases exit) must be at least 2' above this reference
point. In all cases, the chimney must terminate a
minimum of 3' above the highest point of the roof
opening.
(Figure 60)
The 10-foot rule is necessary in the interest of
safety and does not ensure smoke free operation.
Trees, building, adjoining rooflines, adverse wind
conditions, etc., may require a taller chimney
should a smoking problem exist.
