VERTICAL VENTING
(See
Figures 12 and 14
)
Vent the heater vertically in a system in accordance with AS/NZS 5601.1 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 lenghts greater than 16 m (52.5 ft), only one elbow is allowed. Please see Table 6a below for details.
