POINTS TO CONSIDER WHEN VENTING OIL FIRED EQUIPMENT
a. A draft regulator of approved size is recommended. b. Appliance flue connector run to the chimney must have an upward pitch of at least 1/4” per foot of length. c. Chimney flue must extend at least 3 feet above the highest point at which the chimney comes in contact with the roof, and not less than 2 feet above the highest roof surface or obstruction within 10 feet horizontally of the chimney. d. Draft at the breaching should be -0.03 to -0.04 “WC e. Draft “over fire” should be -0.01 to -0.02”WC f. New, high efficiency, oil fired equipment may operate with lower flue gas temperatures causing condensation in the flue. The condensation will mix with the sulphur in the flue gases and create sulphuric acid. The acid will attack the mortar joints in tile lined and brick chimneys, causing corrosion, deterioration, and possible chimney collapse. In instances where condensation, or poor flue condition is detected, a stainless steel liner kit should be installed. Stainless steel chimney liners are shown in the Vent- ing section of this Catalog.
