1.3 Flue Terminal and Ducting
The standard horizontal flue system is suitable for
installations up to 1092mm, measured from the centre line of
the boiler outlet to the outside face of the wall. The wall liner
enclosed will accommodate thicknesses of 400mm and can
be cut to a minimum length of 76mm.
One metre flue extension kits are available to extend
horizontal flues to a maximum length of 3078mm.
90° In-line elbow kits and 135° In-line Bend kits are also
available for more flexible siting. Horizontal flues can be set
at 45° angles to the combination boiler, through 360°, to the
miniature terminal on the outside of the building. The siting
positions for horizontal flue terminals are shown in Figs. 6. -
a) & b).
A Concentric Vertical flue system is available which when
used in conjunction with One metre flue extension kits is
suitable flue heights up to 3 metres to terminate through a
roof.
A Twin tube Vertical flue system is also available for flue
heights up to 8025mm when used in conjunction with one
metre twin tube extension kits.
A Pitched Roof Flashing kit and Flat Roof Flashing kit are
available for use with the vertical flue systems.
135° Off-set kits are available for both concentric and twin
tube. The siting of the flue terminal through a roof is shown
in Fig 6. - c).
Only the above flue systems should be used with Puma
combination boilers.
If a horizontal flue is sited less than 2m above a balcony,
above ground, or above a flat roof to which people have
access, a suitable terminal guard must be fitted. This serves
two purposes, to protect the terminal against damage or
interference and to protect passers-by.
MIN. DISTANCE mm
Note: Where a flue terminal is installed less than 1 metre
from a plastic, or painted gutter, or 500mm from painted
300
eaves, an aluminium shield 1 metre long, should be fitted to
75
the underside of the gutter or painted surface. A suitable
200
wall plate should be fitted to the painted wall surface of a
200
mobile home.

IMPORTANT: It is absolutely ESSENTIAL, to ensure that
products of combustion discharging from the terminal cannot
300
re-enter the building, or any other adjacent building, through
600
ventilators, windows, doors, natural air infiltration, or forced
1,200
ventilation/air conditioning. If products of combustion are
1,200
found to be re-entering any building, the appliance MUST be
turned OFF IMMEDIATELY.

1.4 Air Supply

Detailed recommendations for air supply are given in BS
210
5440:2. The following notes are intended for general
230
guidance: It is not necessary to have a purpose provided air
600
1,200
vent in the room or internal space in which the combination
boiler is installed. If the combination boiler is to be installed
(Fig: 6 - a, b & c)
in a cupboard or compartment, permanent air vents are
required (for cooling purposes) in the
cupboard/compartment, at both high and low levels. The air
vents must either communicate with a room/or be direct to
outside air.
