Installation Pack No 503

MF20 MI-FLEX accessories is a family of installation fitting that have been perfectly designed for use with MI-FLEX 316 and 904 flexible flue liners. When fitted in conjunction together It will make a full system chimney.

General Application

Use this pack when you DO NOT want to remove the existing chimney pot.

These items are to be used in conjunction with MI-FLEX multi fuel flexible flue liner. Building Regulations Document J requires that a flexible flue liner can only be installed completely enclosed inside a masonry chimney. A non masonry enclosure such as timber or plasterboard boxing in is not acceptable. All items are suitable for use on appliances up to 600°C (T600 designation). Suitable for use on Wood <20% moisture, Smokeless coal, Gas and oil.

Installation kits

Installation kits are a complete package designed to give you all you need to install a flue liner in a specific scenario.

Maintenance

The chimney system must be designed to allow for easy provision for sweeping and maintenance. Sweeping must be carried out by competent person. On solid fuel applications a list of HETAS registered sweeps can be found at www.hetas.co.uk. under no circumstances should chemical cleaners or mild steel tools be used to sweep stainless steel chimneys. Cleaning and inspection of the chimney system should be carried out at least once a year, along with maintenance of the appliance, but it is recommended that chimneys serving solid fuel appliances be swept at least twice a year, at the end of the heating season to remove any deposits, which may have built up during the season, and at the start of the next heating season to check for any blockages or deposits. ie. birds nests.

1m Vit Smooth

Application

Suitable for gas, oil and solid fuel appliances with temperatures up to 600°.

VIT-Smooth pipe should only be used as a connecting pipe between your appliance and Flue Liner / Chimney Stack / Twin Wall Flue System.

VIT-Smooth pipe should NOT be used to pass through ceilings or combustible walls.

Construction

VIT-Smooth is a single skin connecting flue system manufactured in zero carbon steel with Powder vitreous enamel coating in a matt black finish.

Suitable for gas, oil and solid fuel appliances with temperatures up to 600°.

Installation

You should not install a piece of VIT-Smooth 125mm within 375mm from combustible material, e.g. wood, plaster boards, etc.

When installing make sure VIT-Smooth is installed the correct way up – the smaller diameter should always be pointing downward. This is because all the condensates will stay within the flue system and not pass to the outside of the VIT-Smooth.

VIT-Smooth is a friction fit joint so dose not require sealing of the joints, For extra security if desired each joint could be coated with a jointing compound (fire cement or high temperature silicone sealant).This makes sure that no condensate can escape and spoil the appearance of the pipe.

VIT-Smooth has been designed to be cut, but care must be taken to cover any exposed steel with high tempter paint as this will rust over time.

When installing appropriate PPE should be worn at all times.

Maintenance

You should make provision for inspecting and cleaning the chimney. This is particularly important on solid fuel applications. You can achieve this by installing a VIT-Smooth with an access doors at changes of direction.

It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.

316L Mi-FLEX

A double skinned flexible flue liner suitable for relining within a masonry chimney. Flue liner is suitable for use with burning gas, oil, coal, coke, cured dry logs, cured dry peat.

Construction

The flue liner has a smooth inner liner made from 316L grade stainless steel and is 0.105mm thick. The flue liner has a convoluted outer skin made from 316L stainless steel and is 0.105mm thick. The Flue Liner is constructed from a single strip of steel which is bent at 180 degrees and then the seam is folded in four planes to give a Omega-Lock seal.

Approval

Flue Liner is approved and listed by HETAS it is also CE approved

Installation – Check List

1 – Make sure the liner will go down the chimney (this can be done by pulling down a small section of the diameter liner you will be using).

2 – Sweep your chimney.

3 – Check you pot is in good condition, if you are NOT using a suspended cowl then remove the pot from the stack.

Installation

Flue Liner should always be fitted from the top.

Make sure the arrows are pointing upwards (gas flow).

Secure a piece of string (at least the same length as the Flue Liner to the Nose Cone.

Now attach the Nose Cone onto the end of the Flue Liner, again making sure the arrows on the Flue Liner are pointing away from the Nose Cone in a upward direction so when the liner is installed the arrows will be pointing to the top of the chimney

Pull the liner down the chimney using the string and at the same time have someone at the top of the chimney feeding the Flue Liner down, once the Flue Liner is fitted remove the Nose Cone.

Maintenance

It is recommended that chimneys serving solid fuel appliances be swept and maintained as frequently as necessary but at least once a year.

Register Plate (F)

Use to seal off the base of the chimney (This Register Plate can be cut on site to fit the base size of your chimney stack). The Register Plate will support vermiculite and stop any debris from within the chimney stack coming down the chimney and hitting your stove.

Construction

The Register Plate and the Supporting Brackets are made from 1.5mm thick galvanised steel. The Register Plate can be sprayed to match the colour of your stove pipe. This Register Plate has a special adaptor suitable for installations which use either 125mm or 150mm diameter flue pipes.

Installation

The four supporting brackets should be cut to the length and width of the base of your chimney stack. Drill a number of holes in the brackets. Now screw them into the brickwork. Cut the Register Plate to the correct size, taking care that the pipe hole lies vertically above the Black Stove Pipe. Drop the Register Plate onto the supporting brackets. Now seal any gaps between the brickwork and the brackets / plate using Fire Cement or High Temperature Sealant. For 150mm diameter installations simply remove the centre cover ring by unscrewing the two retaining screws.
