*only permitted if veranda, porch, deck or balcony is fully open on a minimum of 2 sides beneath the floor, or meets Note 2.
NOTE 1: On private property where termination is less than 2.1 M above a sidewalk, driveway, deck, porch, veranda or balcony, use of a listed cap shield is suggested. (See vents components page)
NOTE 2: Termination in an alcove space (spaces open only on one side and with an overhang) are permitted with the dimensions specified for vinyl or
Figure 25 Vent Termination Minimum Clearances
NOTE 3: Local codes or regulations may require different clearances.
NOTE 4: Termination caps may be hot. Consider their proximity to doors or other traffic areas.
NOTE 5: Location of the vent termination must not interfere with access to the electrical service.
NOTE: Vent system termination is permitted in porch areas with two or more sides open. You must follow all side walls, over- hang and ground clearances as stated in the instructions.
Heat & Glo assumes no responsibility for the improper perfor- mance of the appliance when the venting system does not meet these requirements.
CAUTION: IF EXTERIOR WALLS ARE FINISHED WITH VINYL SIDING, IT IS SUGGESTED THAT A VINYL PROTECTOR KIT BE INSTALLED.
