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. For durability, safety and resistance to corrosion, we recommend you use a flex venting made
from aluminium. Only use flexible venting that is approved for fireplace applications. Flex vent runs must comply with the same limitations as the rigid vent
chart shown here. Flexible vent runs greater than 8’ total are not recommended. Mixed vent runs of both Flexible and rigid venting are allowed providing all
the proper connectors are utilized. See your vent providers’ catalogue for flex to rigid or rigid to flex adaptor numbers.
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.
