How Chimneysafe works

Overview

The product has dual functionality...

  1. to automatically clean the chimney &
  2. to automatically extinguish a chimney fire should a fire occur.
 
 

Cleaning

The cleaning function of the product can/will only be completed when a normal house fire has been lit. When the thermostat at the top of the chimney feels the heat from this fire the unit starts the cleaning process by injecting water mixed with a specially developed chimney fluid /agent into the flue liner. This fluid reacts with the soot and creosote and turns them into a dust/fine ash. This ash/dust is expelled out of the chimney (along with the smoke) by the normal draw of the chimney. No ash/soot/creosote will enter the home and none of the normal soot smell will either.

At installation the installer will place a small camera into the chimney to see the amount of ash/soot/creosote built up in the same. He will then setup the software on the unit to complete a pre-set number of cleaning processes (2, 4, or 6 cleans depending on the dirtiness of the chimney). He will also assign software settings for each individual chimney based on the heat source for the chimney (i.e. open fires or stove/pot belly), and the number of storeys of the residence or business (i.e. 1, 1.5, 2 or 3). All of these pre-settings are entered into the master control via laptop computer application.

Once setup, the first of the cleans will commence after the install is completed and tested (& once a fire has been lit) and the remaining cleans will occur every 10 hours the fire is lit and burning thereafter.

At the end of these cleans the chimney flue will be fully cleared of soot, tar and creosote. From here the system will continue to monitor all actions in the flue liner and will automatically initiate a cleaning function every 200 hours usage there after.

NB There is nothing for the homeowner to clean up and no smells will enter the house.
 

Stages in the cleaning process

The master unit requests a clean to be completed (this is based on the number of hours a fire has been lit in the chimney)
The solenoid valve opens for a predetermined amount of seconds allowing water to pass through.
The water passes though the chemical solution bottle collecting a preset amount of the same and it then enters a mixing value to mix the water/chemical solution.
Once mixed it is passed on through the pipe and it hits the deflector plate in the chimney cavity. The plate deflects the mixture to all sides of the flue/chimney.
The solution pours down the flue/chimney walls reacting with soot, tar and creosote as it does. It breaks down the same into a fine dust.
This dust is extracted from the chimney by the normal draw of the chimney.
     

Extinguishing a Fire

In the unlikely event of a chimney fire occurring the unit will identify the rise in temperature in the flue liner and complete a full extinguishing process.

This process is essentially the same as the cleaning process but the unit allows the volumes of water and cleaning agent to be used in the process to be much greater than with a normal clean.

Note: This process will not only extinguish the fire but it will also clean the flue liner completely.

It should be noted that this extinguishing process will in fact occur/be triggered before the chimney fire actually ignites; this means that this process will actually stop any damage or cracking of the flue liner. Also, it is extremely unlikely that a fire will occur in the chimney at any stage after the unit has commenced its cleaning cycle on installation; the extinguishing function can be considered as merely a safety backup.

NB There is nothing for the homeowner to clean up and no smells will enter the house.
 

Stages in the Extinguish Process

1 The sensor in the chimney records a temperature of >350 degrees Celsius in the chimney.
2 The master unit requests an extinguish to be completed (based on the fact that chimney fires ignite at over 400 deg Celsius)
The solonide valve opens for a predetermined amount of seconds allowing water to pass through.
4 The water passes though the chemical solution bottle collecting a preset amount of the same and it then enters a mixing value to mix the water/chemical solution.
5 Once mixed it is passed on through the pipe and it hits the deflector plate in the chimney cavity. The plate deflects the mixture to all sides of the flue/chimney.
6 The chimney flue is at such a high temperature that the water/chemical solution turns to steam in the ration of 1:6000.
7 The steam suffocates the “fire” in the flue; stops it igniting and performs a clean on it at the same time.
8 All of the steam and soot/creosote/tar is extracted from the chimney by the normal draw of the chimney.

Safety

The safety function of the unit revolves around the fact that the unit cannot and will not engage in any process unless a fire has been lit. Therefore no water or chemical can enter the chimney unless requested by the unit to do so. It is also completely out of sight or reach of children.

Also the unit contains a memory chip that records all the events that have taken place in the chimney (time and date of clean etc etc).

Installation and settings - How easy is it to use?

The product is designed for convenience for the home/business user. Installation of the same should take a maximum of around 2 hours. The requirements for the install are that the attic space where the unit will be located must have electricity and access to a water source.

There are a number of installation settings contained within the unit; the installer sets these at installation according to what height the chimney is (1, 1.5, 2 or 3 storey) and what heat source is at the base of the chimney (i.e. pot belly/stove or an open fire). It should be noted that the unit is not to be used for gas or oil fire chimney systems; it is purely for use with solid fuel chimney/heating systems.

The units’ settings are set by the installer using software/a laptop application. This is completed by them via a USB cable and means that the unit does not need to be physically opened by the installer.

Servicing - how often do I have to service my unit?

The unit will require an annual service by a qualifier installer. This service will replenish the cleaning fluid bottle, change a backup battery contained in the unit (which ensures that the unit will still function even if there is a power cut) and also run a full diagnostic test on the unit to ensure all is functioning correctly. If at any stage during the year the unit stops functioning for any reason an external buzzer in the unit will indicate that a service callout is required (the alarm is a periodic “beep”; the same as a mains smoke alarm). There is a silencer on the buzzer ensuring that it will not stay alarming during normal sleeping hours. When a homeowner hears the alarm; they request a callout by the installer; for safety we recommend they should not light a fire again until the unit has been serviced.
