OR
Downdraft
If you believe that there may be a
downdraft outside of the building,
it may be a good idea to remove
your fan assembly prior to
installation and set the fan gate to
‘0’ to prevent urine odor in the
bathroom. (This is specific to the
electric
models.
)
Install a 12volt fan in vent pipe.
(EXCEL NE) Wood stoves or
furnaces installed in a tightly
sealed room with the toilet may
draw air down the vent pipe.
Downdraft is dependent on
wind direction as well as
natural obstructions etc.
Install the vent so that it goes
above the highest peak of the
roof.
Occasional
Urine Odor
Outside
1) Vent stack not
installed above the
highest peak of the
roof.
2). If vent stack is
installed above
roof line, natural
obstructions, such
as tall trees, being
located in a valley
or close to a hill
may be causing
downdraft.
1) Check that the vent is installed
above the highest peak of the roof.
If not, extend the vent pipe. Guy
wires may be necessary.
2) Add lime to the evaporation
chamber – Contact Sun-Mar for
specific instructions. You will have
to rake more often if you do this.
3) SUN-MAR has a filter box
available (electric units only) which
will filter the ammonia out of the
vented air in a downdraft situation.
Call Sun-Mar for details.
Follow instructions on page 7
& 8.
