9 - Position termination ends so they are free from any
obstructions and above the level of snow accumulaĆ
tion (where applicable). Termination ends must be a
minimum of 12 inches (305 mm) above grade level.
Do not point into window wells, stairwells, alcoves,
courtyard areas or other recessed areas. Do not
position termination ends directly below roof eaves
or above a walkway. Since the G32V is a certified diĆ
rect vent, Category IV gas furnace, the location of
the termination is limited by local building codes. In
the absence of local codes, refer to the current NaĆ
tional Fuel Gas Code ANSI Z223-1 in USA, and curĆ
rent standard CAN/CGA-B149.1 of the Natural Gas
Installation Instructions in Canada for details. The
termination should be at least 12 inches (305 mm)
from any opening through which flue products could
enter the building.
When horizontally vented, minimum clearance for
termination from electric meters, gas meters, regulaĆ
tors and relief equipment is 4 feet (1.2 m) for US
installations. Refer to the current CAN/CGA-B149.1
for installations in Canada or with authorities having
local jurisdiction.
