Figure 23. Allowable Vent Configurations Chart.
ALLOWABLE VENT CONFIGURATIONS:
The vent chart, in Figure 23, illustrates the vent configurations that have been tested and approved for use with this appliance. 45˚ elbows are acceptable for
this installation and may be used instead of 90˚ elbows. You may use two (2) 45˚ elbows for every 90˚ elbow shown in this chart.
This appliance is also approved for use with 5” x 8” flex venting. Only use flexible venting that is approved for this appliance. Flex vent runs must comply with
the same limitations as the rigid vent chart shown here. Flexible vent runs greater than 10’ total are not permitted. When using the flexible vent system, part #
946-601 5” x 8” flex pipe adaptor must be used to adapt from rigid venting to flex venting. This must be attached to the appliance prior to attaching flex venting.
The restrictor settings shown in Figure 23, are recommended. Installation factors such as altitude, prevailing weather conditions such as temperature or
wind, or the number of elbows used may affect your final restrictor settings. Insufficient restriction may cause pilot outages or reduced efficiencies. Too much
restriction may lead to elevated operating temperatures, poor flame appearances, sooting or carbon deposits building up on burner effects or window glass.
Only use the restrictors supplied with this appliance.
