Siting the Ventilator

Survey the property carefully and identify the best site
for the ventilator. Condensation problems, dampness
and mould growth are stimulated by high levels of
humidity, the source of which can be the bath / shower
room, laundry room, kitchen or possibly a damp wall.
Identify an area in the room with an outside wall, which
is clear of obstruction, both inside and out - Check for
water and soil pipes, wiring and other obstructions
before finalizing your installation position.
The external cowl must be positioned a minimum of
500mm away from any gas flue to avoid back flow of
gases.
Indicate the position of the core drill hole on the inside
wall. If possible, mark its position on the outside wall
too. See if they look right.
Remember that the Heat Recovery Ventilator is unique
in that it both extracts stale, damp air and blows in
warmed fresh air. Make sure that steam from your
cooker/hob or appliance is not blown away from the fan.
