Frequently Asked Questions (FAQ’s)
Why are my air inlets puffing smoke?
Combustion gases can build up in the firebox
and ignite as small explosions, causing smoke
to puff out of the air inlets and other openings.
This occurs if the air controls are shut soon
after adding new fuel to a very hot fire. Stop by
opening the air controls to increase combustion
air and burning rate.
What is a flue draught?
The chimney has two main functions:
1)
To safely remove the smoke, gases and
fumes from the house.
2)
To provide a sufficient amount of draught
(suction) in the appliance ensuring the fire keeps
burning.
Draught is caused by the rising hot air in the
chimney when the appliance is lit.
Symptoms of poor performance related to
flue draught include:
• Excessive fuel consumption (high flue
draught).
• Poor burning control and/or overheating (high
flue draught).
• Wind noise from air controls (high flue
draught).
• Difficulty getting a fire going and keeping it
burning well (low flue draught).
• Low heat output (low flue draught).
• Smoke entering room when doors are
opened (low flue draught).
• The construction, position, size and height of
the chimney all affect the performance of the
flue draught.
• Other factors effecting the flue draught
include nearby trees or buildings causing
turbulence.
• We suggest installing a chimney cowl or anti-
downdraught cowl if you are experiencing
issues with draught in your chimney.
• Please note issues with flue draught is out
of the control of Henley Stoves and does not
warrant a service call.
• We recommend you contact a chimney
specialist if the addition of a cowl does not
resolve a flue draught issue.
Why is there no heat from my stove?
1)
If your stove is installed in an alcove, you
need to cap off the area directly above the
stove by installing a 3mm mild steel plinth with
insulation to prevent the heat from escaping.
2)
If the fire continues to consume large amounts
of fuel you may need to check the baffle plate is
fitted correctly and also if there is too much of a
draw up the chimney.
3)
A simple test would be to open the door of
the stove when it is not lighting and listen to see
if you can hear wind in the chimney. If so this
means you will need to install a damper in the
flue to prevent the up draught. We recommend
you contact a piping specialist and install an anti-
up draught cowl.
I’m finding it very hard to light a fire in my
stove? Why is this?
1)
In some houses there may not be sufficient
ventilation in the room for the fire to light
effectively. You may need an additional air vent
in the room to use the stove efficiently.
There is smoke coming out of the stove when
I light it, why is this?
1)
To ensure maximum efficiency and to prevent
the stove from smoking, the pipe at the back to
the stove must be max 150mm before the 45
degree bend in the pipe, otherwise the smoke
will not be able to escape up the chimney.
2)
Stoves that are installed in flat roof houses
or extensions may have this issue due to the
structure of the building.
It may also be because the chimney of your
house is lower than the highest point of your
roof which causes the wind to funnel down the
chimney.
We recommend you install a rotary cowl to
resolve the issue. We recommend you get your
stove installed by a professional.
Why is the glass on the door of my stove
dirty?
1)
Simply open the airwash and pull the lever to
the open position and open the primary.
The airwash is normally located above the door
of the stove.
The glass will become visibly clean.
Please note the glass with become visibilly dirty
when the fire stops.
