Venting; Approved Venting - Heat & Glo Foundation Series Installation And Operating Manual

CAUTION: Consult the local and national installation codes to assure adequate combustion and ventilation air is available.
NOTE: Flame height and appearance will vary depending upon venting configuration and type of fuel used. Venting
requirements apply to both Natural and Propane gas.
STOP: MAINTAIN ALL CLEARANCES AS STATED IN THIS INSTALLATION MANUAL.

*Amperage listed is the maximum required for the appliance with all options.

Refer to the vent systems manufacturer's installation manual for complete installation instructions.
Installation must conform with the venting requirements and restrictions as outlined in this manual.
SEE CHART ABOVE FOR SIZE diameter B-Type Venting that must be used. UL/CSA approved B-Vent only.
DO NOT decrease the vent size.
Vent runs are approved for up to 110 feet with quantity of eleven 90 degree elbows.

Vent runs may also contain a downward component. The downward
component may be a maximum of 6 feet plus the distance to the center line
of the elbow. See Figure 8A.1.
This will be about 87" for 8" diameter pipe and 92" for 10" diameter pipe.
Due to natural buoyancy of flue gas products, venting downward increases
restriction.
Every inch of vertical drop counts as triple inches subtracted off the total
vent run.
Example: a maximum drop of 92" means the total allowed vent run is de-
creased by 276" (23')
Once a downward component has been utilized, the vent cannot go
upwards again, Moisture may get trapped in the vent pipe.
Important: Be sure to do your own calculations based on the center
line dimension given from the pipe manufacture you are using for
your installation.
