Flue Height; Flues; Suitable Material; Connections - Stanley DONARD 60K Installation And Operating Instructions Manual

FLUE HEIGHT

If it is necessary to offset the chimney, the
recommended angle is 60° to the horizontal and the
statutory minimum is 45°C.
Fig. 7
The height of the chimney or flue serving this
appliance should not be less than 4m (13')
measured vertically from the appliance outlet to the
top of the flue terminal, and having a diameter of
150mm (6"). The terminal position should be in
accordance with B.S. 5440 Part 1 and the Building
Regulations.
Note: Never connect to a chimney or flue
system serving another appliance.

FLUES

The chimney and flue pipes intended for use with
this appliance should be mechanically robust,
resistant to internal and external corrosion, non-
combustible, and durable under the conditions to
which they are likely to be subjected.
Flues require a suitable external terminal which
should be designed to permit easy ingress of
combustion products whilst providing protection
against the entry of rain, birds and other foreign
matter into the system. Flue pipes and accessories
such as clips and stays should not be made of
unprotected mild steel or other material which is
likely to corrode.
Where flue piping passes through a closure plate
with a sliding door, ensure that the pipe continues up
and is ultimately connected to the flue liner and well
sealed with fire cement.
Do not connect to a chimney serving another
appliance. Always ensure that the connection is to
a chimney of the same size.

7435.
* Sheet metal conforming to B.S. 715 & B.S. 4076.
* Insulated metal chimneys conforming to B.S.
4543 and B.S. 5440 (a galvanised finish is not

CONNECTIONS

This appliance can either be connected to an
approved masonry chimney or gas flue.
appliance may be connected either direct vertical or
horizontal.
A cast iron 90° bend with cleaning door is provided
with the cooker. A vertical cast iron outlet pipe with
cleaning door is available to order. (See Figs. 5 & 6)
ALL FLUE CONNECTIONS
THOROUGHLY SEALED. Blocked chimneys are
dangerous, keep chimneys and flueways clean; read
the operating instructions.
STANLEY CAST IRON PIPES AND BENDS ARE
HIGHLY RECOMMENDED FOR INTERIOR USE.

NOTE: Maximum horizontal length should not be
more than 300mm (12").

DRAUGHT REQUIREMENTS

While inadequate draught can seriously effect the
efficient operation of the appliance, chimneys over
(5.4m) 18ft. or houses built on high ground can
experience excessive draught. The accepted
draught reading for satisfactory operation is 1.5mm
min. (06." w.g.) 2.5mm max. (0.1" w.g.).

FLUE CLEANING

The flue pipe must be fitted with a cleaning plate,
the flue must be inspected annually and cleaned
when necessary.
