F400 Coaxial Vent Window - NG
• ALL VENTING MUST TERMINATE (END) WITHIN ONE OF THE
SHADED AREAS.
• SET STOVE EXHAUST RESTRICTOR TO THE POSITION THAT
CORRESPONDS TO THE VENT TERMINATION AREA IN THE DIA-
GRAM ABOVE. When termination is exactly on a division line,
use the less restrictive position. For example, if termination is
at 20 ft./10ft., restriction will be set at Position B.
• ALWAYS MAINTAIN THE PROPER CLEARANCES TO
COMBUSTIBLES.
The circled letter designations in the vent diagram correspond
to the Exhaust Restrictor Setting on the stove. First, determine
which vent termination zone is appropriate for your installation
and fuel type, then adjust the restrictor to the corresponding
position as shown in figure 7, page 9.
