Air for combustion must effectively be taken
from outside. Typically, combustion air will be
drawn from a ventilated roof space.
A ventilated loft space complying with section F
of the Building Regulations 1995 (See Approved
Document L2) will be adequate but other options
are possible. If further information is required or
if there is any doubt regarding the adequacy of
combustion air supply, Gledhill Technical Dept.
should be consulted. Combustion air must not
be drawn from within the building.
The appliance location itself should have been
chosen to comply with the relevant requirements
A-CLASS
of the GulfStream Design Installation and
Servicing Instructions.
The concentric flue pipe used in the appliance
cupboard means that the flue can be safely
touched or clothes/towels etc. can be stored
next to the flue and can pass into the roof space
close to combustible material without any extra
protection/insulation being required.
The single flue pipes within the roof space
will become warm and any flammable material
should not be stored adjacent to or on the flue
pipes.
The ridge terminal must not be closer than
25mm to any combustible material, see diagram
opposite.
If a single flue pipe is run through a timber
wall or a cupboard, or via a roof space with
wooden rafters ensure a 25mm gap is left
around the flue pipe, or provide suitable
insulation. Recommendations on protection of
combustible material are given in BS5440 : Part
2 : Clause 20.
