3.5.
FLUE AND TERMINAL INSTALLATION
3.5.1
Coaxial duct diaphragm
The boiler is supplied with diaphragm to be used in relation
to the maximum horizontal or vertical lenght of the coaxial
duct and without additional elbows. See fig. 9 for positioning.
3.5.2 Installations from inside the room
Wall thickness up to 0.5 m [19 in] only, hole diameter 130
mm [19 in], sufficient to accept the optional wall liner kit.
– As previously detailed, a wall liner 129 mm diameter 500
mm [19 in] long is available as an optional extra for use when
fitting the flue air duct from inside the building, [or where it
is required to seal the hole through a cavity wall]. Cut the
liner to the wall thickness, insert into the hole, and seal with
mortar at inner and outer wall faces. Access to the outside
can be made by inserting one’s hand through the liner.
– Fit the rubber-sealing ring onto the largest diameter of the
plastic terminal as shown in fig. 8. Ensure that it is the cor-
rect way around and spray the outside surface with talcum
powder or soap solution to reduce friction.
– Remove the turret from the flue assembly.
– From inside the building slide the duct assembly into the
wall liner until the sealing ring passes completely through
the wall then pull the air duct back until the ring is pulled up
to the wall surface.
– Proceed to section 3.5.3.
3.5.3 Installations from outside the building only
– Fit the rubber-sealing ring onto the largest diameter of the
plastic terminal as shown in fig. 8. Ensure that it is the cor-
rect way around.
