Frequently Asked Questions

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 open-
ings. 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. You may wash the
glass when the stove has cooled down. We recommend you always leave the airwash half open.
My grate has already burned out, why is this?
1) Burning large amounts of soley anthracite coal on a continuous basis the grate will burn out much quicker compared to using the
recommended fuel. We recommend you a mixture of fuels such as turf, briquettes smokeless coal and wood.
2) Not cleaning the grate after every fire will result in the grate buring out prematurely.
How often should I clean my chimney?
1) The chimney and the connecting flue pipe must be swept at least once a year. Ensure you remove any deposits from the oscillating
grates, the firebox surfaces and the flue collar. We recommend you clean your chimney twice a year.
