Commissioning
The gas pressures of the appliance
are factory preset for direct flue
installations and will normally not
require adjustment.
For all Arriva flueing EXCEPT direct
flueing, the appliance must be
down rated as per the instructions
on the commissioning sheet. The
commissioning sheet is located in a
plastic pouch behind the removable
access panel on the right edge of
the combustion chamber glass
panel.
Follow the commissioning
instructions to complete the gas
pressure adjustments, and ensure
correct operation of the appliance.
Setting the air guide vanes
The air guide vanes allow the
installer to set and adjust the
horizontal air flow distribution of
the appliance. These are not to
be confused with the horizontal
louvres that determine the
direction of the vertical flow—
these are fixed and cannot be
adjusted.
The air guide vanes can be adjusted
by carefully bending to the left or
right using a screwdriver.
-
Do not adjust the vanes more
than five times as this may
cause the metal to fracture and/
or break
-
Do not attempt to adjust the
air flow direction while the
appliance is operating or still
hot as this could result in a burn
injury
