•Natural Draft Vertical Venting System Installation

Natural draft venting uses the natural buoyancy of the heated flue products to create a thermal driving head that expels the exhaust gases from the flue. The negative draft must be within the range of 0.01 to 0.08” negative W.C. to insure proper operation. The vent material must be in accordance with the above instructions for vent materials. Vent material must be listed by a nationally recognized test agency.

The maximum and minimum venting length for Category I appliance shall be determined per the latest edition of the National Fuel Gas Code (U.S.) or B179.1 and .2 Installation Code (Canada).

The diameter of vent flue pipe should be sized according to Part 11 of the latest edition of the National Fuel Gas Code (U.S.) and part 7 and appendix B of the CAN/CGA-B149.1 and .2 installation code (Canada). The minimum flue pipe diameter for conventional negative draft venting using double-wall B type vent is 7” for ADB 500, 8" for the ADB 750, and 9" for the ADB 1000.

NOTICE:

Vent Adapter will have to be used to connect B vent to the unit.

The connection from the appliance vent to the stack must be as direct as possible and shall be the same diameter as, or larger than the vent outlet. The vent must be installed to prevent accumulation of condensate and, where necessary, have means provided for drainage of condensate. The horizontal breaching of a vent must have an upward slope of not less than 1/4 inch per linear foot from the boiler to the vent terminal. The horizontal portions of the vent shall also be supported for the design and weight of the material employed to maintain clearances and to prevent physical damage or separation of joints.

•Natural Draft Vertical Vent Termination

The vent terminal should be vertical and should terminate outside the building at least two (2) feet above the highest point of the roof that is within 10 feet. The vent cap should have a minimum clearance of four (4) feet horizontally from and in no case above or below (unless a four (4) foot horizontal distance is maintained) electric meters, gas meters, regulators and relief equipment. The distance of the vent terminal from adjacent public walkways, adjacent buildings, open windows and building openings must be consistent with the National Fuel Gas Code, or in Canada, the latest edition of CAN/CGA-B149 Instal- lation Code for Gas Burning Appliances and Equipment. Gas vents supported only by flashing and extended above the roof more than five feet should be securely guyed or braced to withstand snow and wind loads.

CAUTION:

Listed vent cap terminal must be used and sized adequately to evacuate the flue products from the boilers.

•Natural Draft Vertical Venting With Common Venting System, Category I Appliance Only (NOT To Be Utilized With Add-on Condensing Heat Exchanger)

Manifolds that connect more than one boiler to a common chimney must be sized to handle the combined load. Consult available guides for proper sizing of the manifold and the chimney. At no time should the area of the vent be less than the area of the largest boiler exhaust outlet.

WARNING:

Vent connectors serving appliances vented by natural draft shall not be connected into any portion of mechanical draft systems operating under a positive pressure.

CAUTION:

Vent connectors for natural draft venting systems must be type “B” vent or better.
