2. INSTALLATION INFORMATION
a.
Use the template (supplied with the boiler) to mark the flue position and cut a 130 mm diameter hole for the flue (use
a 127 mm core drill). This size of hole provides sufficient room for the flue to be fitted to the top of the boiler.
Note: If a 110 mm hole is cut for the flue, it is difficult to locate the flue onto the boiler flue adaptor, disconnect the duct
from the bend by removing the fixing screw. After installation ensure the duct is re-assembled onto the bend correctly.
Mount the boiler on the wall as described in the boiler Installation and Servicing instructions.
b.
Fit the flue terminal (supplied with the boiler) to the enlarged end of Duct 'B'. Secure with two screws supplied with
the terminal as shown in Fig. 3.
c.
Extend the telescopic flue to its full length. From the inside, pass the assembly through the wall. Seat the flue bend
onto the boiler flue adaptor.
d.
From outside, push the terminal in towards the wall until the screws securing the terminal are in line with the outside wall.
See Fig. 4.
Note: If there is no access to the outside wall, refer to Appendix 1.
e.
Carefully remove the flue assembly from the wall. Seal and secure the joint between the ducts with the sealing tape
supplied.
f.
Position the rubber seal over the 90° bend as shown in Fig. 5.
g.
Fit the inside flue sealing collar over the flue, see Fig. 5. From the inside, pass the flue assembly through the wall.
h.
Secure the 90° bend to the boiler using the clamp and rubber seal. Ensure that the seal covers the bend and adaptor
joint. See Fig. 6.
i.
Make good the inside and outside walls with the flue collars. See Fig. 6.
Note: The second flue collar is supplied with the boiler.
