12.4.1 Standard Vertical installation:
Secure the flashing kit to the roof.
Refer to Fig. 18.
Measure the distance from the contact rim on the flashing
kit to the flue support ring on top of the boiler.
This is dimension ‘Y’.
Lay the Terminal Assembly flat and loosely connect the Flue
Tube Adaptor Assembly and the Appliance Adaptor.
Measure the overall length from the contact rim lip to the
base of the adaptor.
This is dimension ‘X’.
Subtract dimension ‘Y’ (actual) from ‘X’ (uncut), add 3mm,
this will give the cutting length ‘Z’.
Take the assembly apart and shorten the inner and outer
tubes by dimension ‘Z’. Remove any burrs.
Fit the Appliance Adaptor to the top of the appliance using
3 screws provided.
Slide the Flue Tube Assembly onto the Appliance Adaptor.
From the roof, slide the Terminal Assembly through the
flashing kit.
From the appliance side, position the terminal clamp bracket
and loosely secure to the roof. Fig. 19.
Locate the base of the Terminal Assembly into the Flue Tube
Adaptor Assembly From the roof, ensure the contact rim of
the flashing kit has slid up inside the outer tube of the Terminal
Assembly.
Secure the Terminal Assembly to the Flue Adaptor Assembly
and Flue Adaptor Assembly to the Appliance Adaptor. Drill
(2mm drill) through the pilot holes and secure using the
screws provided.
Fully secure the Terminal clamp bracket.
Tape around both joints to give an air tight seal.
Make good around the flashing kit.
