VENTING
INSTALLING A RESTRICTOR
Some vent configurations may require a restrictor plate be installed. The restrictor for this fireplace is installed on the inside top of
the fireplace and is to be slid open or closed. Loosen the screws on either side and slide the restrictor as desired. Do not modify the
restrictor(s). Please use the graph above to determine if you will need to use a restrictor.
CONFIGURATION
35
mm
Loosen these two Phillips head
screws to slide the restrictor on/off.
BEWARE OF ELBOWS
Elbows create resistance to the movement of air through your venting configuration and they must be included when determining
your minimum and maximum vent lengths.
There must be a minimum vertical rise of 20” (508
mm)
before any elbow.
Elbows are called either ‘vertical’ or ‘horizontal’ depending on their mounted position. The two types of elbows are:
TYPE N
- 45° or 90° elbows which transition from vertical to horizontal and vice versa. This can be called an
upright
elbow.
TYPE Q
- 45° or 90° elbows which transition from horizontal to horizontal. This can be called an
flat
elbow.
No more than four 90° elbows OR eight 45° elbows OR a combination totaling no more than 360° ‘elbow degrees’ are allowed. For
example, a combination of two 90° elbows and two 45° elbows is allowed (90° + 90° + 45°+ 45° equals 270°) but a combination of
three 90° elbows and three 45° elbows is not allowed (the total equals 405°.)
APPLYING THE RESULTS
The first (3) N elbows do not need to be included in venting calculations. For an elbow-degree count greater than 270°, the
following applies:
•
for either
Type N
elbow you must add 40” (1m) to your
THS
•
for a 90°
Type Q
elbow you must add 80” (2
m)
to your
THS
•
for
each
45°
Type Q
elbow you must add 40” (1
m)
to your
THS
Once you have found your total vertical section (
TVS
) and your total horizontal section (
THS
) plot the intersection of these two
numbers on the appropriate chart, below.
The intersecting block will have one of three entries;
0
,
35
, or
X
:
If your
TVS
and
THS
intersect at a block with an “0” the configuration is possible without a restrictor.
If your
TVS
and
THS
intersect at a block with an “35” the configuration is possible and a 35 mm restrictor must be used.
If your
TVS
and
THS
intersect at a block with an “X” the configuration is not possible.
For venting configurations that intersect at an “X” a power vent option may be available.
