NOTES:
1. The asterisk (*) denotes parts that are
included with the Mighty Venter kit.
2. To calculate the equivalent vent pipe
length, add the straight pipe plus 10 feet
(3.0m) for every 90° elbow and 5 feet
(1.5m) for every 45° elbow.
3. In order to use 100-foot (30.5m)
equivalent length of vent pipe with the
model 1670 boiler, consult factory. A
14 inch (356mm) vent pipe may be used.
4. To be used for single boiler installation
only.
5. Note that the Mighty Venter diameters
shown are for both the inlet and the
outlet of the Mighty Venter.
6. The vent pipe reducer kit includes item
D. And one of: Item E, Item G, Item H.
(As shown: varies per model.)
7. Reference Item “L” is used only with the
500 boiler. It is included with the
20069301 Mighty Venter kit.
8. The vent system must be adequately
supported to prevent sagging. But in no
case shall the supports be less than
every three feet (0.9m).
9. The venting system must be sloped
upward not less than ¼ inch per foot
from the furnace to the vent terminal. The
vent system must be installed to prevent
collection of condensate.
10. Side wall vent hood location: Read all
installation/operation information
concerning vent hood location before
installing.
