Alpha Top Easy-Flue
Appendix 3 - Extending the Top Easy-Flue 500
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.
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. 11.
c.
Remove the Duct B assembly from Duct A by pulling in the direction of the arrows. See Fig. 12.
Fig. 11
d.
Fit a 750 flue extension (Part No. 1000320) to Ducts A and D using the clamps and seal supplied, as shown in Fig. 13.
Connect any additional extension in the same way.
Note: Ensure that the end of the outer duct with the two holes is connected to Duct A.
Fig. 12
e.
Continue to add flue extensions until the assembly is within 200 mm of the outside wall, ensuring that the overall
maximum length with Duct B fitted, will not be more than that given in Appendix 2.
Note: To gain the correct length, only cut the flue extension ducts (ensure that the cuts are square, free from burrs
and the ducts are not distorted). Do Not cut the Easy-Flue ducts.
