IV. FLUE CONNECTION
WARNING: The flue pipe diameter must not be less than the recommended diameter for the outlet
of the appliance, stated below. Avoid using bends greater than 45 degrees to the vertical.
WARNING: All joints in the flue system must be effectively sealed. Check the appliance for
soundness of seals between castings and main components prior to use.
The stove must be connected to the chimney using 125mm (5”) diameter flue pipe and is supplied ready
for top or rear flue connection. It is recommended that this connects to 150mm (6”) flue pipe as soon as
possible to prevent blockages occurring. This must travel at least 600mm vertically before any change of
direction. It is important that connector pipe is made from 24-gauge steel or cast iron and is more than
455mm (18”) away from any combustible wall or ceiling. Please follow the manufacturer’s instructions for
passing through walls and ceilings.
The stove is designed to connect to a flue system such as masonry or pre-manufactured lined pipe system
that meets Building Regulations. If you intend to use existing masonry chimney it is important to check
for cracks in the liner. If the masonry flue is not to specification the flue should be lined with a Class 1
stainless steel liner.
Any existing stainless steel liner should be carefully checked for buckling, warping or cracks prior to
installing your stove. It is also necessary to clean your liner and chimney using a qualified, HETAS
†
approved chimney sweep.
Check the flue is functioning correctly and ensure all products of combustion are vented to the
atmosphere through the chimney terminal.
Do not use single wall chimney connector pipe as a chimney on any stove. Connect your stove to an
approved flue system serving only one appliance.
All pipe joints and the connection to the heater collar must be firmly secured.
External flues must be insulated to prevent heat loss.
