Incinerator Flue Clearing Kit

Smart Sweep Mini - Incinerator Flue Clearing Kit

The Smart Sweep Mini utilizes a rotating head fitted with nylon flails to break up any deposits on the flue wall. The flail head is advanced up the flue pipe with sections of flexible POM rod and is rotated with the use of a cordless power drill (not included in the kit). The speed of rotation determines the force applied by the flails.

However, because the flails are made from nylon, the flue is not damaged during use even when a high speed is selected.

What you will get with this kit

5 x 1.00 metre POM rods There are five rods supplied with this kit – providing sufficient assembly to remove removes deposits of soot and fly ash. All rods are very strong and flexible, made from 10mm diameter solid POM.

1 Drill Adaptor The Drill Adaptor should be used in a conventional drill chuck. Drills should be set without hammer action.

1 Flail Head with 8 Flails The Flail Head is designed to remove loose soot particles and fly ash from the walls of the flue.

1 Bristle Head The bristle head is connected to the rods using an identical coupling system as the rods themselves, does not require rotation and is simply pushed using the hand grip.

1 Hand Grip Designed to be used with the bristle head when cleaning both horizontal and vertical sections of the incinerator toilet.

Once the flail head has been used to clear most of any debris or ash build up, it can be replaced with the bristle head for final cleaning if necessary. The bristle head is connected to the rods using an identical coupling system as the rods themselves as shown in the illustrations. It does not require rotation and is simply pushed using the hand grip. It can be used with as many rods as are necessary to brush the entire vertical flue or, normally, just with one rod to clean the horizontal section of flue connected to the incinerator toilet.

When maintenance requires the horizontal flue to be cleaned, it is normal practice to disconnect the incinerator toilet and move it away from the flue and combustion air pipes. Given such access, the bristle head can be used to clean the flue.

Connection of the rods is achieved using special plastic male and female couplings. Unlike some conventional sweeping rods, the Smart Sweep Mini couplings do not rely on screw threads to make the connection and so can be rotated in either a clockwise or anti-clockwise direction. The couplings contain flat sections to transmit rotational torque and spring clips to prevent them from separating. When required, the couplings can be separated by pressing in the spring clip button and pulling the couplings apart. The connection details of the male and female couplings are replicated in the operating heads and the adaptor for the cordless power drill.

Changing the flails

If Flails need to be replaced, the grub screw in the top of the dome is loosened. The existing flails can be withdrawn. Two new sets of 300mm long flails are inserted from each direction and cross over in the middle of the head so that about 130mm projects from each quarter of the head surface. Once the flails are correctly located and with the steel disc correctly located, the grub screw is fully tightened. As the grub screw is secured it applies pressure onto the steel disc and ensures that the two lower sections of the flail head are forced apart by the captured flails and locks them in position.

Connecting the rods, heads or drill adaptor

Connecting the rods, heads or drill adaptor
To connect two rods, align the flat sections and the button of the two halves, depress the Spring Clip Button and push the sections together until the button snaps out indicating a secure joint.

Separating the rods, heads or drill adaptor
To separate the connectors, firmly depress the button and the two halves can be parted. The Flail Head and the Plunger Head are both designed to be "snapped" onto the Male end of a Rod and the Drill Adaptor snaps into the female end of a rod.
