FLUEING
Once the flue is assembled and penetrating the wall, install the Horizontal Terminal and secure the
17.
termination to the flue using the sheet metal screws provided.
Note: If the flue terminal position is more than 1800 mm above a safe working surface, then suitable
equipment will be required to enable safe access to fit the flue terminal.
Alternatively, the flue terminal may be fitted to the flue
assembly prior to the assembly penetrating the wall.
18. Make a final adjustment to the Adjustable Straight
Length, if required, to ensure the end of the outer skin of
the flue terminal extends a minimum of 75 mm from the
face of the external wall.

Firmly tighten the compression band on the
Adjustable Straight Length to prevent the pipe from
extending or compressing its length over time.
Apply an adequate bead of sealant around the flue assembly and exterior wall of the building, using a
19.
general purpose silicone sealant suitable for outdoor application.
Failure to properly seal the flue penetration through the wall will result in long term damage due to
weather conditions.
20. Apply an adequate bead of sealant on the rear face of a Trim Ring, using a general purpose silicone
sealant suitable for outdoor application.

Fit the Trim Ring over the flue terminal and press against the wall.
Apply an adequate bead of sealant around the flue assembly and interior wall of the building and on the
21.
rear face of the Trim Ring, using a general purpose silicone sealant suitable for indoor application.
Press the Trim Ring against the wall.
Install a Condensate Trap (PN 295139) to
22.
the condensate drain spigot on the water
heater flue outlet if the flue has a change
of direction from horizontal to vertical or if
there is a long vertical rise directly from
the water heater.

Install a condensate drain line to the
Condensate Trap.
