A “spillage” test must be made before the
installed unit is left with the customer.  Follow
the procedure below:

1) Start all exhaust fans in the home and then

close all doors and windows in the room.

2) Light the unit and set controls to maximum.

Turn fan off.

3) After five minutes, test that there is a “pull”

on the flue by placing a smoke match,
cigarette or similar device which gives off
smoke, in front of the spill tube. To ensure
a valid test, place a scrap piece of sheet
metal (or other non-combustible material)
between the spill tube and the upper lou-
ver, this will prevent the natural convection
of the unit from interfering with the test. See
diagrams below.

The smoke should be drawn into the spill tube,
if it does not, leave the unit for a further five
minutes and retest as above. If the smoke is still
not drawn into the spill tube, turn the unit off and
check for the cause of the lack of draft. If
necessary, seek expert advice.

For wind turbulent sites, a wind cap may
remedy the problem.
