VENT TERMINATION CLEARANCES
The final position of your fireplace depends on the location of the vent termination in relation to the clearances that must be observed as shown in Figure 5 on page 6.
The vent system serves as the “chimney” as well as the combustion air supply (air intake). The horizontal run must have a rise of 1/4" (.6 cm) for every12"(30.48cm)ofhorizontalruntowardsthe termination.Themaximumhorizontalrundepends ontheverticalrisefromthefireplaceadaptercollar to the vent termination (see table below).
