**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 non-vinyl siding and soffits. 1. There must be 91.4 cm minimum between termination caps. 2. All mechanical air intakes within 3.0 M of a termination cap must be a minimum of 91.4 cm below the termination cap. 3. All gravity air intakes within 91.4 cm of a termination cap must be a minimum of 30.5 cm below the termination cap.

Figure 37 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.
