VERTICAL VENTING
(See Figures 19, 19A and 20)
Vent the heater vertically in a system in accordance with local codes and local
codes. Double-wall vent connector is recommended; however single-wall pipe is
allowed in some circumstances. Consult your local code official for detailed
information. Do not use a draft hood with this heater.
To connect a double wall metal gas vent to the heater, order the appropriate
Metal Flue Collar from the chart below:
1. See Table 6 to determine allowable vent sizes for your heater.
NOTICE: Table 6 is for installations in which the total lateral vent length (that is, the horizontal distance from
the flue collar to the main vertical portion of the vent) is less than half the total vent height (the vertical
distance from the flue collar to the vent termination) and which have three or less elbows in the system. For
vent lengths gr
eater than 16 m (52.5 ft), only one elbow is allowed. See Table 6a below for details.
