OFFSET CHART CHIMNEY INSTALLATION
It may be necessary to offset the chimney in order to clear a joist or an obstacle. The three (3) charts below will assist you in selecting
the proper combination of elbow angle and chimney length(s) that will provide the necessary degree of offset within an available height.
1. Select the column with the proper
chimney diameter of your system.
2. Determine the distance of the off-
set required by dropping a plumb line
for an accurate measurement. The
offset is measured at the chimney
centre line as per the "A" Offset
measurement in the diagram below.
3. On the chart, find the predeter-
mined distance (under the "A" col-
umn) required for the 15
o
elbow. For
greater offset, use the 30
o
or 45
o
offset charts.
4. After finding the offset, look at the
“B” (height) measurement in the chart
to find the specified height. The
appropiate "chimney lengths" re-
quired in between elbows is found in
the left hand side column on the
chart.
NOTE:
•
UltraTemp chimney can be
offsetted using 15
o
, 30
o
or 45
o
elbows.
Combining offsets for a greater angle is
not permitted.
•
One pair of (two) 15
o
, 30
o
or
45
o
elbows may be used per interior
installation.
•
Never install an elbow in a joist
area. Chimney sections must pass
vertically through framed joist areas.
•
Each elbow support will sup-
port 30 feet of chimney.
•
An intermediate support must
be used at 4 feet intervals in conjunction
with an elbow support.
•
The maximum length of
chimney allowed between elbows is
16 feet.
All measurements in inches.
Construction tole one inch.
