ROGUES GALLERY

Over the 30 years I have been trading in this industry you come across something that makes you go “well I’ll go to the foot of our stairs”. 
They vary in degrees from very serious to scratching your head in total disbelief. But what they all have in common is that they are dangerous or just detrimental to your property.

We all carry mobile phones now so capturing an image is relatively easier than it was thirty years ago I never carried a camera with me back then so there are more images of the present era than from back then. Here is a varying degree of images and scenarios that we stumbled upon along the way.

If you notice any similarities with your own Fireplace or Chimney perhaps you should take note…

EXAMPLE OF SPILLAGE

The term “Spillage” means the products of combustion are not able to vent the chimney correctly for varying different reasons, they spill out the front of the appliance being used and enter the room.

If this is a solid fuel, wood or coal it’s very obvious you have a “SMOKEY FIRE” with the stains and smell to go with it. A gas appliance would be harder to identify as there would be minimal signs in the room or odour. This could be down to the fact the appliance was installed incorrectly in the first place or lack of maintenance, problems escalate over time. Annual sweeping and servicing with the mandatory tests carried out to ensure the appliances and flue system function correctly would identify any problems with the appliance and flue system. Below is just one scenario example.

SIGNS OF SPILLAGE

The appliance is a Jetmaster open fire. If you look above the Jetmaster on the stone surround you can see where smoke has stained the stone indicating that the appliance is not removing the products of combustion into the flue which is highly dangerous as this will mean “Carbon Monoxide” entering the property. We had to condemn the installation until a solution was found.

There could be a number of reasons for this to occur:

  • Lack of ventilation into the room causing the flue to choke
  • The throat of the flue not being correctly tapered and having flat spots causing the draw in the chimney to slow down
  • A blockage in the chimney itself, soot build up where it has not been maintained, birds nest, mortar from the initial building of the chimney not being removed when it was constructed, affectionally known as “Snotts”
  • An incorrect terminal or blocked terminal A flue has not been constructed to Building Regulation Document J

AFTER INVESTIGATION

Once we removed the appliance and looked up the chimney we found “Snotts” blocking the lower bend, they had been there from day one and were never removed from when the chimney was built partially blocking the flue.
Once they had been removed we smoke tested the draw of the chimney to prove that was the case.

OUTCOME

The customer had lost faith in the old Jetmaster which is only 47% efficient, we ended up installing a Stovax Riva 55 inset stove 84% efficient and controllable on a flexible liner with a new Honed granite back panel.

CHIMNEY & FIREPLACE FAULTS

The “Example of spillage” above is just one of the scenarios we have been faced with. Here is a selection of pictures taken from different locations across the area we cover. The appliances range from Open fires, Wood-burning / Multi-fuel stoves and Gas appliances. What they all have in common is they will cause a chimney to vent incorrectly. This could in some cases lead to problems, including fatalities by carbon monoxide poisoning. Hence it is law to have a Carbon Monoxide alarm installed in the room with every appliance. The problems would be smoke entering back into the room, there would be signs of spillage with soot staining and smoke damage on the fireplace. In some instances of very bad chimneys, there will be signs of this on the wall and ceiling with a creosote / smoky smell in the air and on the furnishings in the room.

If you sat in your chair at home in front of your Open fire, Wood-burning stove, or gas fire and there is any similarity pictures to your own Scenario… Now would be a good time to act.

Birds Nest, Complete blockage
A dented flue in a garage, the appliance was in the sitting room on the other side of the wall
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Birds nest inside of a Flexible liner connected to a floor standing gas boiler, no bird guard installed
Whoever installed the liner to the appliance, installed a liner that was to short for the chimney By about a meter, hence why the birds could build a nest. very bad practice
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar
Looking up a chimney that should have been swept years ago
Wire mesh installed and overlapped in a rain cap, the holes are to small. This will get frequently blocked up
The same rain cap as picture 19 looking at the side elevation
Bricks laid across the throat of the opening for a gas fire partially blocking the flue
Looking down the chimney we found a brick blocking a flue half way down… most bizarre
The brick that was inside the flue from picture 21
Cement partially blocking the flue when the chimney was constructed, it also helped stop the twigs
Looking up at cement snotts in a chimney
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Hornets nest in the top a chimney. I got down the ladder faster than I went up
Once we had disconnected the stove it became obvious why the stove was smoking back into the room
Collapsed Flexible liner in a chimney due to incorrect fuel being used
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the terminal. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the terminal. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the terminal. Lack of maintenance, slumbering or burning wet or unseasoned wood
Creosote / Tar build up inside the flue. Lack of maintenance, slumbering or burning wet or unseasoned wood
Flat spots inside a flue will never funnel the smoke correctly, you should have nothing less than 45 degrees inside a flue or throat leading into the flue
This fireplace spilled products back into the room due to the poor throat leading into the chimney
Looking up at cement snoots in the lower bend of the chimney
Had the right idea but just badly designed
Looking up a chimney at a bird’s nest completely blocking the flue
Cob webs in a flue used for a gas fire
A ventilation cowl installed on a working chimney with wire mesh as a bird guard
Wire mesh pushed inside the top of a brick chimney without a chimney pot, presumably to stop the birds nesting. But can you spot the Jackdaw feather...?
Badly altered chimney, this brake so many rules we ended up installing an electric unit
Looking down inside an old chimney the bricks between the two flues (the feathers) have disintegrated. This will allow fumes to enter the adjacent flue
Looking down the chimney the flue should be the same cross-sectional area as the chimney pot
Looking down the chimney at a rotted out Flexible liner
Cement partially blocking the flue when the chimney was constructed
A flue pipe just pushed up the flue without a liner with rock-wool insulation wedged around it.
An air brick sealed outside with silicon and a water pipe for the outside tap knocked through it. All appliances need air for combustion and for the flue to function correctly.
Bricks blocking the flue, they were holding the chimney pot in place when it was first installed and never chipped back once the chimney pot was set in position.
