This boiler shall not be connected to any portion of a mechanical
draft system operating under positive pressure.
1.The vent pipe must slope upward from the boiler not less then 1/4 inch for every 1 foot to the vent terminal.
2.Horizontal portions of the venting system shall be supported rigidly every 5 feet and at the elbows. No portion of the vent pipe should have any dips or sags.
3.This boiler series is classified as a Category 1 and the vent installation shall be in accordance with chapter 7 and 10 of the National Fuel Gas Code noted above or applicable provisions of the local building codes.
4.Inspect chimney to make certain it is constructed according to NFPA 211. The vent or vent collector shall be Type B or metal pipe having resistance to heat and corrosion not less than that of galvanized sheet steel or aluminum not less than 0.016 inch thick (No. 28 Ga).
5.Connect flue pipe from draft hood to chimney. Bolt or screw joints together to avoid sags. Flue pipe should not extend beyond inside wall of chimney. Do not install manual damper in flue pipe or reduce size of flue outlet except as provided by the latest revision of ANSIZ223.1. Protect combustible ceiling and walls near flue pip with fireproof insulation. Where two or more appliances vent into a common flue, the area of the common flue must be at least equal to the area of the largest flue plus 50 percent of the area of each additional flue.
