4.
Carefully remove the template inserted as the middle pages of this installation instructions booklet.
Cut along the middle of the
bold
circle marked “Cut Line”.
5.
Align the top of the circular template with the mark on the wall.
It may be convenient to tape the template to the wall.
6.
Mark the pilot hole through the centre of the template and scribe around the template onto the wall.
The scribed circle should be 150 mm in diameter.
Remove but
DO NOT DISCARD
the template.
7.
Drill a pilot hole using a 6.5 mm diameter or smaller drill bit.
The drill bit must be long enough to penetrate completely through the outer skin of the external wall.
Note:
Ensure the drill remains level and straight during this step.
8.
Align the centre of the template with the pilot hole on the outside wall surface and scribe around the
template onto the wall.
The scribed circle should be 150 mm in diameter.
Remove the template.
9.
Drill or cut the flue termination hole through the wall using a cutting tool suitable for the wall construction.
Note:
The Trim Ring (PN 295125) will cover a 150mm diameter hole.
10.
Starting from the 90° Bend 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.
11.
Secure each flue component using the sheet metal
screws provided.
12.
Support horizontal sections at a distance no greater than
2 m using a Wall Bracket (PN 295129).
13.
A horizontal run of flue connecting directly to a Horizontal Flue Terminal must have a downward gradient
to the flue terminal.
Use Male to Male and Female to Female Adapters to reverse the direction of flue insertion where
three or more sections of flue are used in a horizontal flue run and the flue drains toward the flue
terminal. Refer to the
diagram
on page 31.
This provides for proper draining of condensate without pooling at the flue component joins.
14.
A horizontal run of flue between two bends, where the bend closest to the flue terminal is
orientated
upward
, must have a gradient upward in the direction of the flue terminal.
Note:
A Condensate Trap and condensate drain line must be installed if the flue has a gradient upward
in the direction of the flue terminal. Refer to step 22.
15.
The Adjustable Straight Length (PN 295127) may be required if a special length is required between
offsets or changes in direction of the flue or to ensure the outer skin of the Horizontal Flue Terminal
extends a minimum of 75 mm from the face of the external wall.
The Adjustable Straight Length can be adjusted from 560 mm to 890 mm by pulling on its end to
increase its length or pushing on its end to decrease its length.
16.
Fit a Trim Ring over the last section of flue prior to penetrating the wall.
