Damper Fitting Instructions
Prior to installing a damper, ensure that it's location will
allow it to spin freely once installed. Ensure that the damper
will be in a convenient location without obstruction from the
top of the stove or cleaning access doors in the fluepipe for
example. During installation, safety goggles / glasses should
be worn at all times.
The following steps should ensure a simple installation :
1. Remove spindle from the main body. This is sometimes
not as easy as it would appear, as the spring needs sufficient
pressure exerted to enable satisfactory working when
installed. A good method is to hold the damper by the main
body with the pointed end of the spindle facing upwards,
then carefully apply pressure downwards onto a scrap piece
of wood or similar. When the main body is lowered down the
shaft, twist the spindle to release the two main parts.
2. When free and decision has been made as to the location
of the damper, a 6.5mm (1/4" approx) hole must be drilled at
opposite parameters of the flue pipe. Drill very carefully as a
snug fit is best. Extreme care should be exercised when
drilling - especially into vitreous enamelled flue pipe. Masking
tape may be applied to limit chipping. If the
pipe has a cleaning access door, the holes must be below the
access door !
3. Once the holes are drilled, the main body of the damper
needs careful sliding into the flue pipe to the location of the
holes. Whilst in situ, slide the centre of the spindle through
the main body of damper, twisting where necessary to refit
in it's original location through the main body.
4. Prior to installing the flue pipe with damper fitted, check
that when the handle is horizontal, the damper also is
(damper closed) and when vertical, that the damper also is
