INSTALLATION INSTRUCTIONS Cont...
VENT RESTRICTORS
All vent installations above 20' (6.1 m) require the use of 60%
restrictor.
The restrictor is installed in the exhaust of the appliance.
Vent Restrictors
Due to the extra flow produced by certain venting configurations vent restrictors must
be placed in the vent to maintain performance. When your installation requires a vent
restrictor you must remove the flue baffle and install the restrictor in the exhaust box as
shown below. The restrictor is fastened in with 2 screws represented by the dotted
line in the figure below. Once the vent restrictor has been installed the flue baffle must
then be re-installed.
Note: The unit must be cooled to room temperature before installing the restrictor.
