Wayne HSG200 Manual - page 4
Pitch the horizontal run of the flue pipe upward 1/4 inch
(6.35mm) per foot (.305m) or more. Run directly to the
chimney, fasten joints securely and support horizontal
runs to prevent sagging.
If the flue pipe must be extra long, it’s size should be
increased. The horizontal length of the flue pipe should
not exceed the height of the chimney above the flue
connection.
The draft control should be hood type per Figure 2 or, IF
APPROVED BY LOCAL AUTHORITIES, a single
barometric damper suitable for gas firing per Figure 3.
The draft control should be sized the same as the flue
pipe per Figure 1, and should be located higher than the
highest part on the appliance flue passage. Refer to the
barometric draft regulator manufacturer’s instructions for
complete detail.
NOTICE: Should the flue pass through a partition,
the draft control must be located in the
same room as the heating appliance.
