Models HEP, HEPL and HEPL2 venting systems are primarily intended to be installed in fire resistive, non combustible surroundings or in unenclosed installation. They are not intended for use in one or two-family dwellings. (CAUTION: Do not enclose this venting system in chase or passageway made of wood or other combustible material.)
Where the venting system extends through any zone of a building outside the area in which the heating appliance connected to it is located, it shall be provided with an enclosure having a fire resistance rating equal to or greater than the fire rating of the floor, wall or roof assemblies through which it passes.
Models HEP, HEPL and HEPL2 venting systems may penetrate a combustible roof or wall using the Ventilated Roof Flashing assembly. For wall penetrations, the use of the Wall Firestop assembly is required. This is the only part intended for use with combustible construction. All other parts, such as Anchor Plate and Wall Support, Wall Guide and Floor Guide are for attachment to non-combustible construction.
Where, according to local code, no chase enclosure is necessary, models HEP, HEPL and HEPL2 may be placed adjacent to or on each pipe section and in the individual listing; see "CLEARANCES". Contact local building or fire officials about restrictions and installation inspection in your area.
