Horizontal Co-Linear Vent Kit (Masonry Fireplaces Only)
APPLICATION
This instruction applies to the DuraVent DirectVent Pro termination system and is intended as a supplement to the applicable DirectVent Pro instructions.
This termination and venting system and the gas appliance were tested and listed by an accredited test agency.
Kit # 46DVA-HCL33 includes:
1 Horizontal Termination Cap
2 x 10' (3 m) long x 3" (76 mm) round liners and hardware.
The 948-128 Mil-Pac sealant must be purchased seperately.
The intake and the exhaust are 3" (76 mm).
INSTALL INFORMATION
The flue damper must be fully blocked open or removed if safe to do so for installation of the unit. The smoke shelves, shields, and baffles may be
removed if attached by mechanical fasteners. Ensure the fireplace and chimney are clean and in good working order, and that all chimney cleanouts are
tight-fitting and not permitting air into the chimney. Install a sealed vent cap and metal flashing at the top of the masonry chimney to prevent leaks and
air movement within the cavity. A vent restrictor is not required when terminating horizontally, as shown below.
This appliance is only certified for use with NG when terminating horizontally (LP is not permitted). Make the hole on the outer portion of the masonry
fireplace by boring it or removing bricks. Ensure that the masonry structure is safe and brick can be removed without damage to the chimney prior to
proceeding. Minimum and maximum vent heights are noted below.
