8.6.7 Vertical terminal installation
When the heater is installed as a Type C
1. Confirm that the roof flashing is correct for the type of roof through which the terminal is to be installed. (See Section 8.11)
2. Determine the desired location for the flue terminal, taking into account minimum distances as detailed in Section 8.3.1 and the
relevant British Standards.
3. Taking care to protect the appliance from debris and dust, drill a hole in the desired location. The diameter of the hole should be no
more than 10mm greater than the diameter of the air supply pipe of the terminal.
NOTE: The hole should be drilled from the outside to ensure that no damage is done to the roofing material. Extra care should be
taken to ensure that the hole is drilled vertically.
4. Install the roof flashing and secure as appropriate.
5. Carefully insert the roof terminal through the roof flashing and hole in the roof.
NOTE: When inserting the roof terminal do not support or turn the terminal using the cap.
6. Ensure the terminal is vertical using a spirit level.
7. Fit the support bracket around the terminal and secure using appropriate fixings. Do not tighten the support bracket.
8. Install the remainder of the flue system working progressively away from the Water heater supporting the pipes as necessary.
9. Once the flue system is fully installed, tighten the clamp to secure the terminal in place.
