Example:
A 10' section of rigid pipe and a 90° elbow may be used in conjunc-
tion with a 3 ft. flex section (PFL-3) will, when extended in a chase,
allow for a maximum horizontal run of twelve and one-half feet from
the centre of the fireplace to outside wall and a minimum of 7'6" when
retracted in opposite direction.
(See
Figure 16.
)
Long Vent Runs:
For longer or more complex vent runs, vertical lift is required. First
ensure that the planned run is acceptable using the Vent Graph. Plan
out the required components using the chart above. You may be able
to use fewer components using the chart,

rigid and flex venting.

RHS101 Heat Shield for short horizontal installation.
Install by sliding over the vent pipe where it connects to the
termination.
"D" flex sections and "E" solid sections may be used in conjunction
with one another to obtain different possible horizontal length instal-
lations.
NotE:
Flex section must not exceed maximum horizontal
length of 3 feet, and for this application the top clearance is to the
ceiling.
Installation

. Vertical venting with 1 offset (1 offset= two 90° bends).
Minimum
clearance to combustible construction around the
vent pipe is 1"
on all sides must be maintained, except on hori-
zontal venting where the
top
of the pipe must have a clearance of
at least 2".
2. offset Vertical Installations
A maximum oftwo offsets
(each offset has two 90° bends)
may be
made if the length of the offsets does not exceed 25% of the vertical
vent height, when measured center to center of piping.
Example:
Typical vent installation.
30' vertical vent
2 - 2' offsets required
25% of 30' = 7-1/2' max. offset allowed
This venting configuration meets requirements.

Maximum vent height is 30 feet above fireplace.
Note: Flame characteristics will change if the maximum vent
height is used.
