The heaters are designed to be installed as room sealed
appliances. The flue and air intake are run as separate
pipes to the special concentric wall or roof terminal. The
wire mesh inside the fresh air adapter on the heater must
be removed prior to installation. See Page 51, Figure 31.

11.3 Flue Installation
The fan outlet may discharge vertically or horizontally.
Connection should be made using 100 mm minimum
diameter Aluminium or Stainless Steel flue material to
National Standard and must be adapted to insert into the
100 mm flue adapter. Both fresh air supply and flue duct
shall not exceed 10,000 mm. HE15 and HE20 flue must
be insulated if longer than 5,000 mm. HE25 flue must be
insulated if longer than 8,000 mm. For each 90° bend,
subtract 1,000 mm from the maximum flue length. The

In order to locate fans that are not IP54 protected away
from the wet environment, a 100 mm diameter extension
tube between the heat exchanger end and fan must be
installed. This length must be subtracted from the
maximum flue length.

11.4 Ventilation Requirements
Detailed recommendations for air supply are given in the
relevant National Standards. There must be an adequate
supply of air for both combustion and general ventilation.
Air vents should have negligible resistance. Do not locate
air vents where they can be easily blocked or flooded, or
adjacent to any flues or extraction systems carrying
flammable vapour.
