2. Refit to the terminal, ensuring that the clips (1 & 2) are engaged and
secure.
3. Loosen screws (3) and rotate the entire outlet assembly to redirect
the plume. Tighten screws (3) to secure in the required position.
The flue terminal outlet has built-in stops to limit rotation
for horizontal flues to allow condensate to run back into
the boiler for safe disposal. Do not attempt to force
beyond the limit stops.
