SHALL NOT BE CONNECTED INTO ANY PORTION OF A MECHANICAL DRAFT
SYSTEM OPERATING UNDER A POSITIVE PRESSURE.
INSPECT CHIMNEY to make certain it is constructed according to the latest revision of
the NFPA 211. Local regulations may differ from this code and should be checked. Where
there is a conflict, the local code will prevail.
The Starfire 3 must be installed into a chimney which has a masonry or metallic chimney
liner.
An unlined chimney will have leaks that will cause poor chimney performance (NO
DRAFT), and could result in a positive pressure in the combustion chamber.
Horizontal portions of the venting system should not exceed 10 feet in length. Horizontal
lengths over 10 ft. will have a negative effect on the chimney performance.
The chimney should extend at least 2' above any portion of the building within 10'. See
figure 9 below. It should produce a -.02 inch W.C. draft in the combustion chamber. See
chart, below, for recommended chimney or vent sizes.
Inadequate draft will cause improper combustion, resulting in dirty flue ways and high
fuel bills.
CONNECT FLUE PIPE same size as boiler outlet to chimney, sloping upward continuously
toward the chimney approximately 1/4" per foot. Bolt or screw joints together to avoid sag.
If an oil fired water heater is vented into the same flue as the boiler, provide a separate
hole into the chimney whenever possible. When this isn't possible, use a "Y" connection in
the flue pipe, using a separate draft regulator for each unit. When a chimney will not provide
adequate draft to handle the input from the water heater and boiler simultaneously, wire the
units so that only one will operate at a time, favoring the water heater.
