VERTICAL FLUE INSTALLATION
Suitable flashing (not supplied) is required to waterproof the roof penetration.
Notes:
Ensure each flue component is fully engaged and the rubber seal on the inner duct is well seated at
each joint.
Each flue component is supplied with screws to connect to the adjacent flue component. The screws are
located in a bag taped to the outside of the flue component.
Refer to diagrams:
“Typical Installation – Vertical Flue”
on page 32, and
“Typical Installation – Vertical Terminal with Vertical and Horizontal Sections”
on page 32.
To install a vertical flue and termination:
1.
Determine the location where the flue will penetrate through the roof.
Note:
Ensure there are no rafters, purlins, pipes or electrical cables located in the roof where the flue is
to penetrate.
2.
Drill or cut the flue termination holes through the roof and ceiling of a suitable size to allow the
installation of the flue, using a cutting tool suitable for the roof construction.
3.
Install a Condensate Trap (PN 295139) to
the condensate drain spigot on the water
heater flue outlet.
Install a condensate drain line to the
Condensate Trap.
Refer to
“Draining the Condensate”
on
page 29 and to
“Condensate Trap and
Condensate Drain Line”
on page 30.
4.
Connect the first flue component to the water
heater flue outlet.
Fit the end of the flue component down
over the water heater flue outlet as far
as it will go.
Ensure there is a minimum 35 mm and maximum 42 mm
overlap, the rubber seal on the inner flue is well seated
and the flue component is fully engaged on the water
heater flue outlet.
Secure the bend to the outlet with the screws provided.
5.
Continuing from the first flue component and working
towards the terminal location, connect all of the other flue
system components.
Ensure each flue component is fully engaged and the
rubber seal on the inner duct is well seated at each joint.
6.
Horizontal flue runs between bends must have a minimum
upward gradient towards the flue terminal of 20 mm per
metre.
Note:
Ensure that the seam of the inner flue in horizontal
runs is towards the top of the installation.
7.
Secure each flue component using the sheet metal screws provided.
