C5 Installing the External Vertical Powerflue (EVP)
The EVP is designed to have the box containing the fan and electricals
mounted externally for installations.
The EVP installation must be weather proof and conform to all local
council standards including powered flue roof termination rules.
The cowl surround should be fixed in place as shown.
Depending on the kit purchased, mount the EVP kit to the top of a
chimney flashing plate or penetrate the roof with an optional flue liner
accessory and fit the EVP kit over the flue liner; sealing the penetration
with a decktite or similar flashing. Ensure the terminal is vertical and
rigidly mounted and the flexi flue attached below is fixed to the
terminal spigots using the supplied hose clamps and is held in place by
drilling 3 holes and screwing 3 self tapping screws evenly around each
hose band clamp (as shown in the picture below).
