VENTING
The GABO Gas Stove has been tested and listed for installation with 4” X 6 5/8” Simpson DuraVent GS
®
,
AmeriVent Direct

and Selkirk DT

direct venting components. For specific installation requirements, fol-
low the installation instructions included by the venting manufacturer with the venting system components
you have chosen. The total vent length may not exceed 36 feet, including vertical rise and horizontal run.
The vent lengths are measured from the stove, not the floor. The minimum vertical vent rise when using a
vertical vent termination is 10 feet. The minimum vertical rise required when using a horizontal vent termi-
nation is 2 feet. The maximum allowed horizontal vent run is 12 feet when the venting includes at least 5
feet of vertical rise. The maximum allowed horizontal vent run for vertical rises of less than 5 feet is shown
in the venting charts. No more than three elbows may be used in any installation. The venting charts are
set up for installations that use no elbows or that include the use of one elbow. For the second or third el-
bows that are included in the installation, add 4 feet to the actual horizontal run for each elbow to determine
the equivalent horizontal run for the installation.
The venting charts allow a simple way to determine the recommended initial settings for both the air inlet
restrictor and the exhaust baffle. These settings have been determined by extensive testing and will be a
good starting point while setting up the stove. Small adjustments from these settings may be needed to ac-
count for specific installation variables. Please see the instructions on pages 19 & 20
for information on
how to adjust the restrictors.
The numbers (1-7) designate the position of the air inlet restrictor. The higher the number, the greater the
restriction. There is a position indicator line on the adjuster handle. When ½ or ¾ is added to the number
designation, this indicates that the position is halfway or three-quarters between adjacent numbers. Use the
long lines which represent the halfway position between the numbers as a guide. The letters (A-F) indicate
the position of the exhaust baffle. The higher the letter, the greater the restriction. Use the top edge of the
adjuster handle as the position indicator. When +,
⅛
, ¼,
⅜
, ½,
⅝
,
¾ or
⅞
is added to the letter designation,
this indicates that the position is fractionally between adjacent letters. For example, E
⅞
is halfway be-
tween E ¾ and F. Use the lines between the letters as a guide. F
⅛
is the first line past F. If F + corre-
sponds to your recommended settings, this is halfway between F and F
⅛
. Note: Although some of the rec-
ommended settings represent only small incremental differences on the setting indicators, the change in the
actual air inlet restrictor or exhaust baffle position is significant.
To use the charts, determine the horizontal run length and vertical rise length (in feet) for your installation.
If more than one elbow is used, add 4 feet to the actual horizontal run length for each additional elbow to
calculate the equivalent horizontal run for the chart. Note: Remember that a maximum of three elbows is
allowed. Select the venting chart for the fuel type (Natural Gas or Propane (LP) Gas) and find the box on
the chart that corresponds to the vertical rise and actual horizontal run (or equivalent horizontal run, if two
or three elbows are used) and read the settings for the inlet air restrictor (1-7) and exhaust baffle (A-F
⅛
).
Examples are shown page 9. Use these as a guide for your particular installation.
Note: The GABO is shipped from the factory with inlet air restrictor and exhaust baffle set for 2 feet of
vertical rise and 1 foot of horizontal run and for natural gas.
The GABO is shipped with a Simpson DuraVent GS
®
starter section that is specifically designed for the
GABO. Regardless of the venting brand you chose, you must use the DuraVent starter section that was
provided with your stove. All of the venting brands listed for use with the GABO are compatible with the
provided starter section. For venting system installation details, refer to the instructions provided with the
venting system you have chosen. Each brand has specific installation requirements that must be followed to
insure a safe and functional venting system for your GABO.
