VENTING ENVELOPE
MIRAGE 18 / 30 CO-AXIAL VENTING CHART
NO VENTING OPTION
Note: The vent must
not exceed a total
length of 28 feet.
Any combination of
rise and run may be
used but must be
constrained to the
boundaries of this
chart. A Maximum of
three (3) 90° elbows
may be used. Only
one (1) 90° elbow or
combination of other
elbows equaling 90°
can be used without
reducing horizontal
run. For each addi-
tional 90° elbow, or
an equal combi-
nation of elbows,
reduce horizontal
vent run by 2 feet.
Ensure vent pipe is
properly supported.
Co-axial Venting
The Mirage 30 can be vented using co-axial components, or co-linear components for venting
through an existing fireplace and chimney. Maximum and minimum venting lengths can be found
on the venting charts - co-axial (Figure 4) & co-linear (Figure 5).
