CONNECTOR RISE:
Connector rise is the length of the pipe connecting the top of the
draft hood to the system breeching above. The diameter of this
pipe varies depending upon BTU input, chimney height and the
length of the connector. Fig.4 (Dim. “B”) shows the location of this
pipe in a typical application. Table 3 depicts the proper diameter
(Dim. ”C”) of the connector rise depending upon its total length
(top of the draft hoods to the breeching above).

HORIZONTAL BREECHING
CONNECTOR LENGTH:
The maximum length of the horizontal breeching connector length
between the chimney and the closest boiler shall not be longer
than one foot per inch of horizontal breeching connector diameter,
i.e. if the horizontal breeching connector is 16” D., the maxi-
mum length from the chimney to the first boiler would be 16
X 1 FT. or 16 feet. The minimum length shall be one foot regard-
less of the horizontal breeching connector diameter. See figure 4.
