28. Vent Termination Clearances When planning the installation consider the location of the vent terminal and clearances Some of the most common clearances to keep in mind are shown in Figure 9 Important All vent clearances must be maintained Check your vent termination clearances against Figures 9 and 10 The vent should be placed so that people cannot be burned by accidentally touching the vent surfaces when the stove is operating The vent termination should be located where it cannot be damaged by such things as automobile doors lawn mowers or snowblowers and it should be located away from areas where it could become blocked by snow etc Some considerations are Obstructions or impediments to venting Nearby combustible materials that could come into contact with combustion exhaust gases Other nearby openings within 9 229 mm through which exhaust gas could reenter the building All vegetation within 3 914 mm that may interfere with the draft Other factors that influence where the installation will be sited include the location of outside walls where additional heat may be desired in the home where the family members gather most regularly and perhaps most importantly the distance limitations of the venting IMPORTANT system A Direct Vent Only The horizontal termination must not be recessed into the exterior wall or siding Horizontal vent runs must be level toward the vent termination
