Masonry
Chimneys
This furnace
can be vented into an existing
masonry
chimney.
This
furnace
must not be vented
into a chimney
servicing
a solid
fuel
burning
appliance.
Before
venting
furnace
into
a chimney,
the
chimney
MUST
be
checked
for
deterioration
and
repaired,
if
necessary.
The chimney
must be properly
lined and sized per local
or national
codes.
If furnace
is vented
into a common
chimney,
the chimney
must be
of sufficient
area to accommodate
the total flue products
of all
appliances
vented
into chimney.
The following
requirements
are provided
for a safe venting
system:
1. Be sure that chimney
flue is clear of any dirt or debris.
2. Be sure that chimney
is not servicing
an open fireplace.
3. Never reduce pipe size below the outlet size of furnace.
4. All pipe should
be supported
using
proper
clamps
and/or
straps. These supports
should be at least every 4 ft. (1.2 M)
5. All horizontal
runs of pipe should have at least 1/4 in. (6.35
mm) per ft of upward
slope.
6. All runs of pipe should be as short as possible
with as few
turns as possible.
7. Seams should be tightly joined
and checked
for leaks.
8. The flue pipe
must not extend
into chimney
but be flush
with inside wall.
9. The chimney
must
extend 3 ft. (.91 M) above highest
point
where
it passes through
the roof of a building
and at least 2
ft. (.6 M) higher
than any portion
of a building
within
a
horizontal
distance
of 10 ft. (3 M). It shall also be extended
at least 5 ft. (1.5 M) above
highest
connected
equipment
flue collar.
