HOW SPEEDFIT WORKS

Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless steel teeth to grip the pipe and an ‘O’ ring to provide a permanent leak proof seal.

Use of the

Superseal Pipe Insert ensures a double ‘O’ ring seal.

An ‘O’ ring at the head of the insert and the shape of the stem, provide a secondary seal against the bore of the fitting. A combination of this and the main ‘O’ ring ensure a good connection.

The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the chance of leaks if a side load is applied.

The head of the insert has been designed for ease of insertion.

The additional benefit of Twist and Lock Fittings is that a twist of a screwcap locks the pipe in position and gives increased compression on the ‘O’ ring for even greater security.

MAKING A GOOD CONNECTION

PREPARE THE PIPE

Fittings and pipe should be kept clean bagged and undamaged before use.

Pipe Cutter

JG TS

Speedfit

Barrier Pipe

Ensure the pipe is free of score marks. Cut the pipe square.

When using Speedfit Barrier Pipe cut along an insertion mark. We recommend the use of JG Pipe

Cutters.

To prevent damage to the ‘O’ ring remove all burrs and sharp edges.

When connecting Speedfit Pipe use a Superseal Pipe Insert. A twisting motion will aid insertion.

The insert should only be used with Speedfit Pipe.

NEW TWIST AND LOCK FITTINGS

Gap between Cap and Flange

Pipe mark indicates full insertion

The fitting should be in the ‘unlocked’ position, this is shown with a small gap between the screwcap and the body flange.

Push the pipe fully into the fitting, up to the pipe stop. If the Speedfit Pipe has been cut correctly the insertion mark on the pipe will be level with the collet head. The ‘O’ ring on the Superseal Pipe Insert provides a secondary seal against the bore of the fitting.

A good connection has been made.

If you are not using collet clips, ensure that the screwcaps are in the locked position.

Pull to check it is secure. It is good practice to test the system prior to leaving the site or before use. Our recommended test procedure is shown in our Technical Checklist.

ADDED BENEFIT TWIST AND LOCK

Twist the screwcap until it touches the body flange.

This increases the ‘O’ ring seal around the pipe and locks the pipe into position.

STANDARD SPEEDFIT FITTINGS

Push pipe up to stop

Secondary Seal

Pipe mark indicates full insertion.

Standard Speedfit connections are made in the same way as Twist and Lock.

Push Pipe up to Pipe Stop. If the Speedfit Pipe has been cut correctly the insertion mark on the pipe will be level with the collet head.

Pull to check connection is secure and test the system. Our recommended test procedure is shown in our Technical Checklist on page 29.

TO DISCONNECT

Ensure that the system is depressurised.

The screwcap on Twist and Lock Fittings will need to be turned back to the unlocked position.

Push the collet square against the face of the fitting by using fingers or with the help of our collet release tool.

With the collet held in position the pipe can be removed.

The fitting can be used again without the need for replacement parts.

WHAT

NOT

TO DO

Don’t use hacksaws to cut the pipe or leave burrs on the end of the pipe.

✗

Don’t use damaged or scored pipe.

✗

Fitting may be gripped but not sealed if pipe is not fully inserted.

✗

Don’t forget to push the pipe fully into the fitting, past both the collet (gripper) and the ‘O’ ring.

Do not insert fingers into the fitting as the stainless steel teeth may cause injury.

Remember to pressure test the completed installation according to the recommendations in our Technical Checklist.

07

PIPE STOP DISTANCES

Stops are located at the following distances from the end of the fitting: size 10mm 15mm 22mm 28mm stop distance 20mm 30mm 35mm 44mm

COLLET COVERS

Use a collet cover or collet clip to provide added security against pipe disconnection, e.g. the fitting coming into contact with rigid surfaces and behind dry-lining walls.

Collet covers for use with standard Speedfit fittings, are available in white or in red or blue to allow colour coding of pipes.

Collet cover

STOP END

Stop end

The unique feature of the

Speedfit Concept, the ability to disconnect the fitting should you want to, means the Speedfit Stop End not only provides a permanent leakproof seal, but can be readily removed to allow work to restart or to allow an extension to a system.

Thus, the fitting is especially useful to allow water to be turned back on, overnight for instance, or if a job has to be interrupted for another reason.

Stop ends are also useful when pressure testing a system before appliances are connected.

STEM ELBOW

Designed to simplify pipe connection in restricted spaces. The Speedfit

Stem Elbow provides an instant swivel fitting so pipe can be orientated in any direction.

A special 10mm version gives a neat connection from concealed plumbing to a radiator

.

COLLET CLIPS

Collet clip

SERVICE VALVE

Collet clips are available in grey and white for use with standard fittings to prevent accidental pipe disconnection.

Red or blue collet clips provide colour coding of pipe on twist and lock fittings.

They are not designed to prevent accidental release and should be fitted when the fitting is in the locked position.

RELEASE AID

The action of pressure in a system could increase the grip of the collet. The release aid allows a firmer grip on the collet whilst removing the pipe.

Release aid

The Speedfit range of brass chromium plated service valves can be used on both hot and cold water services and central heating. Push fit connections mean much reduced installation time, especially in confined spaces.

The valves, in 10 to 22mm, have a 1/4 turn open/close mechanism operated by a screwdriver slot or a lever.

Tap connector patterns have a u n i o n n u t t o c o n n e c t direct to a tap or floatvalve.

Lever operated valves are supplied with both a blue and a red indice.

The ability of Speedfit products t o t w i s t w h i l s t i n s i t u allows the screwdriver slot operating valve to be turned out of sight, helping to avoid unauthorised tampering.

Mechanism twists out of sight

TAP CONNECTORS

Speedfit manufacturer a wide range of connectors including conventional straight and bent tap connectors.

The range also offers a special and unique Tap Connector that only requires a simple hand tightening to connect up a terminal tap, mixer or float valve. An integral seal within the fitting avoids the need for further sealant. The connectors are useful when replacing existing brassware or in other confined spaces.

Coupling up to a supply is easy. The pipe is simply pushed home into the Speedfit connection and is instantly secured, without the need for specialist tools.

FLEXI HOSES

SPEEDFIT MANIFOLD

Speedfit have introduced an innovative 22mm x 10mm 4 way manifold. Departing from the usual manifold design, this new product has 4 in-line 10mm outlets, offering a neater envelope size and therefore a much smaller installation space.

Other benefits include better flow characteristics and a more even distribution of hot water.

The 22mm and 10mm Speedfit push-fit connections make for a fast and easy installation, even in confined spaces.

Whilst designed as a heating product, the manifold can also be used in a mains pressure hot or cold domestic plumbing system, to feed bathroom or kitchen taps and mixers. This allows for a more efficient installation as every terminal fitting has its own dedicated supply.

APPLIANCE TAP

The Speedfit range includes an Appliance Tap for the permanent connection of washing machines and dishwashers, thus enabling complete water isolation to the appliance.

Manufactured to a quality you would expect from Speedfit, our range of Flexi Hoses has 40 different patterns.

Available in lengths from 150mm to 1,000mm, ends are either push fit to union nut or push fit to push fit, including hoses with an integral service valve operated by a 1/4 turn screwdriver slot.

Apart from being aesthetically pleasing the new white hoses offer more flexibility and a larger through bore for better flow characteristics.

A simple push fit connection of the supply pipe and a plastic thread on the outlet to marry well with the plastic thread on the hose means the Speedfit Appliance Tap is very easy to install. The large round handle is easy to grip and turn.

SUPERSEAL PIPE INSERT

The Superseal Pipe Insert has been developed to be used with Speedfit Barrier Pipe and Speedfit Fittings to provide an extra line of defence when installing a Speedfit Push

Fit System.

The insert has it’s own ‘O’ ring which, with a stem sliding within the inside of the pipe, gives a secondary seal against the inside of the fitting.

More specialist patterns have been designed to help the installation of monobloc mixers to a 15mm supply.

Sold in pairs, each hose in the pair has a different spanner location to ease connection of the threaded end into the monobloc’s inlets.

The hoses are suitable for cold water up to 10 Bar and hot water (65˚C max) up to 6 Bar and approved by WRAS.

The Speedfit Connection, when made with the insert, has a number of design features.

Sliding the stem of the insert into the pipe gives greater compression of the main ‘O’ ring on the pipe and greater rigidity of the length of pipe within the fitting, reducing the chance of leaks if a side load is applied.

A connection is easier to make because the head of the insert has been designed for ease of insertion.

Superseal Inserts are listed on page 14.

SYSTEM CONNECTIONS

CONNECTION TO COMPRESSION FITTING

Many but not all compression fittings are suitable for use with plastic fittings and pipe. Users should therefore check for compatibility. Compression fittings with short tube stop depth or brass olives should not be used with plastic fittings or pipe.

When using compression fittings with Speedfit Pipe, a

Standard Pipe Insert (prefix TSM) must be used to withstand the compressive pressure of the olive. The olive must be located within the the length of the pipe insert and the pipe fully inserted into the fitting. The connection should not need more than 2 full turns after the olive has gripped the pipe. JG Speedfit recommend the use of soft copper olives.

Ensure nut and olive are in place before inserting pipe insert.

Compression fitting Standard Pipe insert

Olive Speedfit Pipe

CONNECTION TO IMPERIAL PIPE AND FITTINGS

The Speedfit Range includes couplers to connect

Speedfit Pipe to 1/2” to 1” BSP and BSPT. See page 12.

Fittings to connect imperial pipe to metric pipe are shown on page 10.

CONNECTION TO CHROME-PLATED COPPER PIPE

Speedfit fittings can be connected onto chromium plated copper pipe if the chromium plating is completely removed to the full depth of the fitting. To ensure maximum grip, the fitting of a collet clip is recommended.

It is not possible to connect Speedfit fittings to Stainless

Steel Pipe.

Collet clip

CONNECTION TO MAINS SUPPLY

In modern properties, water enters a building usually in blue MDPE (medium density polyethylene) pipe. In order to comply with Water Regulation Schedule 2.10, the internal plumbing system should be connected via a

Speedfit Stop Valve (Part Nos. 15STV and 22STV) in conjunction with a PE-Copper Coupler from the Speedfit range of Underground Fittings.

Speedfit Pipe with Superseal Pipe Insert

Stop valve

Copper pipe

PE copper coupler

MDPE pipe with

Pipe Insert

Connection of Speedfit pipe to supply pipe of other materials should be via a stop tap with a 15mm or

22mm compression outlet.

CONNECTION TO RING MAINS

Water-replenishing ring mains are typically used in hotels and hospitals. They are maintained at a constant high temperature to supply hot water to distribution pipes to wards or hotel rooms which may be some way from the heat source.

These systems are very different from more conventional domestic hot water and central heating systems.

Speedfit Products cannot be used on ring main systems.

The exception would be those systems designed for domestic situations which have an intermittent temperature of less than a maximum of 65ºC. This is in accordance with BS7291 Parts 1 and 3 Class S.

CONNECTION TO BOILERS

Speedfit pipe should never be connected directly to a boiler.

Although most modern boilers have a high limit thermostat, residual heat can be conducted by the heat exchanger. Therefore, Speedfit recommend a minimum of

1 metre from the boiler casing should be run in copper pipe unless otherwise stated in the boiler manufacturers installation literature.

A gravity primary circuit operating on an uncontrolled cooking range or solid fuel boiler should be run entirely in copper and the heating circuit run in copper for the first metre.

Refer to BS 5955: Part 8 for further clarification.

All appliances should have safety devices to make sure they cannot operate above the working temperature and pressure range set out in our Technical Checklist on page

29. If safety devices are not incorporated within the appliance then external controls will be needed.

Water meters (and other devices) can contain check valves that prevent the expansion of heated water back down the main supply from a combi boiler. If plastic pipe is to be used, a suitable expansion vessel must be fitted.

This is especially important to consider if a water meter is fitted retrospectively. Speedfit do not recommend the use of plastic pipe on the main supply between a water meter and a combi boiler if an expansion vessel is not fitted.

Speedfit Products should not be fitted to a sealed system oil boiler, back fired boiler or other uncontrolled heat source.

Please also see Drop-Pipe Systems on page 17 and

System Commissioning and Flushing on page 21.

CONNECTING TO OTHER PLUMBING FIXTURES

As shown in the Product Range List, the Speedfit range of fittings includes valves, taps, adaptors and connectors for the plumbing of all typical domestic appliances and fittings.

CONNECTION TO CYLINDER & WATER HEATERS

Speedfit can be used on sealed and open vented heating systems, where boilers are either heating a hot water storage cylinder or instantaneous hot water such as a combination boiler. The temperature and pressure limits of the system must not exceed the maximum values stated under the heading ‘Working Temperatures and Pressures’.

When using a traditional copper vented cylinder Speedfit pipe and fittings can be installed with direct connections to the cylinder.

16

17

CONNECTION TO CYLINDER & WATER

HEATERS CONTINUED

Unvented pressurised cylinders can be installed using

Speedfit Pipe and Fittings. However, insertion depths on compression joints that form part of the cylinder must be checked prior to installation and the use of standard pipe inserts (Prefix TSM) is recommended.

In accordance with current U.K. Building Regulations

(Part G), discharge pipes from temperature and/or pressure relief valves must be run in metal pipework.

Speedfit connections to combined Cylinder/Boiler units and Thermal Storage Units must be made outside the casing unless otherwise stated in manufacturers installation literature.

DROP-PIPE SYSTEMS

Care should be taken when designing and installing a central heating system where radiators are supplied by pipe work which drops from an upper floor.

With this kind of system it is possible to trap air in the upper floor pipe work. When the boiler is fired the increase in pressure within the pipe caused by expanding air could cause the pipe to burst.

It is therefore essential that the system be designed so that any air can be removed from the system either automatically or manually by installing automatic or manual air vents at the highest points of the system.

DISCHARGE PIPES

Speedfit pipe should not be used to provide the discharge from unvented cylinders, unvented water heaters and sealed systems via the temperature relief and pressure relief values.

CONNECTION TO COPPER PIPE

The minimum distance to make a solder connection on copper pipe inserted into a Speedfit Fitting is 450mm

(18 inches). Ensure that any residual flux solder is not allowed to come in contact with the fitting. That same measurement is the safe distance to use a freezer kit to

Speedfit Pipe.

CONNECTING TO COLD WATER STORAGE TANK

To install the Speedfit Tank Connector, unscrew the nut and push the body of the fitting through the tank hole with the washer on the inside of the tank.

Hand tighten the nut onto the body. Push the pipe into the connector.

Note: Hand tightening the nut onto the body is all that is required. Further mechanical tightening will damage the fitting.

CONNECTION TO PUMPS AND VALVES

Speedfit pipe should be connected to circulating pumps, motorised valves in accordance with the section in this book headed, “Connecting Plastic Pipe To Compression

Fittings”. If Speedfit pipe is not mounted on a supporting structure, the pipe must be clipped close to the components’ connections to ensure adequate support and to assist in the reduction of vibration.

For heavier equipment, ensure that appropriate metal brackets provide full and independent support of the components and that it does not rely solely on the pipework for support.

WATER HEATERS

Speedfit recommend that mains supply pipework to unvented water heaters (up to 15ltr capacity), be run in metal pipes.

UNVENTED PRESSURISED CYLINDERS

Unvented Pressurised Cylinders can be installed using

Speedfit pipe and fittings. However if the safety parameters of the cylinder exceed those of the pipe and fittings it is possible to fit a pressure reduction valve on the out going hot supply pipe. This will not interfere with any other cylinder safety devices demanded by regulations as they are all fitted in the incoming side of the cylinder. Run a short length of copper pipe from the cylinder connection (about 150mm - 300mm) then fit a

Honeywell DO5F pressure reduction valve. This will protect the pipe and fittings from excessive pressure in the event of boiler / cylinder malfunction. The factory fitted temperature / pressure relief valve on the cylinder will discharge below 100˚C therefore protecting the pipe from excessive temperature.

PREVENTING BACK FLOW

The Speedfit range includes a Double Check Valve

(Part No 15DCV) to enable installers to comply with Water

Regulation Schedule 2.15, thus preventing contamination o f w a t e r a r i s i n g f r o m back siphonage, backflow or cross connection.

RADIATOR CONNECTIONS

The most common way of running pipework to a radiator is to run both flow and return pipes central to the radiator position.

The pipes exit a single gang box (fitted with rubber grommets) located at the mid height of the finished radiator position. This also provides a fixed point for other trades to work to and reduces the risk of damage to the pipework.

Once the plasterboard is installed the pipes are passed through the Speedfit Radiator Outlet Plate to exit plasterboard without the need of unsightly holes.

Metal reducing sets which convert radiator valves from

15mm to 10mm are not suitable for use with Speedfit

Fittings or Pipe as they can cause damage to the plastic.

ELECTRICAL CONTINUITY

The plumbing or heating system installer should have these aspects checked to ensure compliance with current

IEE regulations. If in doubt please contact the Speedfit

Technical Advisory Service or your local Electricity Authority.

ELECTRICAL CONTINUITY CONT’D

IEE Guidance Note 7 provides useful guidance on the design of electrical installations where there is increased risk of electric shock. It recognises that the requirement for supplementry bonding may be relaxed where metal taps and plastic pipes supply other bathroom fittings.

Similarly a metal bath or radiator not connected to an extraneous-conductive-part is not required to be connected to the local supplementry conductors.

INSTALLING PIPEWORK

SPEEDFIT BARRIER PIPE

Speedfit Barrier Pipe is manufactured to BS 7291 Parts 1,

2 and 3 Class S and is Kitemarked.

It is made up of 5 layers, the centre of which is a blue coloured oxygen barrier which prevents the ingress of air into the system, thereby reducing the effect of corrosion on metal components.

2. Metal window frames are not required to be supplementary bonded unless they are electrically connected to the metallic structure of the bonding.

3. Metal baths supplied by metal pipes do not require supplementary bonding if all the pipes are bonded and there is no other connection of the bath to earth.

4. All bonding connections must be accessible and labelled

“Safety Electrical Connection - Do Not Remove”.

Because of it’s low thermal conductivity, when carrying hot water, Speedfit Pipe is cooler and therefore safer to touch. Relatively low heat loss through radiation means that a system retains it’s heat longer and delivers hot water more quickly and with less wastage than a metal system.

PIPE BENDING

Gentle bends can be made with pipe clips on either side of the curve, positioned to maintain the bend radius.

Tighter bends can be achieved by using the cold forming bends shown on page 15.

Internal Bending Springs are available in 10mm to 22mm sizes, see page 15.

It is also possible to bend Speedfit Pipe using a standard pipe bender. The pipe should not be heated with a blowlamp or hot air gun.

Minimum bend radii for Speedfit pipe are as follows:

-

100mm 175mm 225mm 300mm

For bends of radii smaller than those shown, standard elbow fittings are recommended.

PIPE SUPPORT AND CLIPPING

There are two types of pipe clip in the Speedfit range.

Firstly, a nail clip is used for fixing to timber when running concealed pipe work i.e.

underfloor or in a roof space . This clip takes less time to fit and is compact which allows pipework to be fixed close together when space is at a premium.

The second type uses a screw and therefore takes a little longer to fix. When pipes are required to cross over, it is possible to add a spacer to the clip. This will give room between the pipe and the wall to allow the pipes to cross over. If pipework needs to be insulated, using the spacer will give room for the lagging to be applied.

Pipe clips should not be fitted any closer than 60mm from the end of the fitting to allow for expansion. Pipes should always be adequately supported to prevent undue stress or side load on the fittings.

The flexibility of Speedfit pipe gives it the ability to be threaded through concealed or inaccessible spaces without disruption to surrounding structures, making major savings in installation time.

Pipework can be “cabled” through drilled holes in joists and rafters. Therefore, pipework can be installed after floorboards have been laid, working below the floor before the ceiling is installed.

This makes site work far safer as the installer does not have to balance on open joists with the risk of dropping tools or equipment on other people below.

Joist Speedfit pipe

Clips

This will also eliminate the risk of damage by floorboard nails. There is no need for dry runs since pipe can be cut and connections made in-situ.

Rigid pipe, such as copper, can only be fed under floor in short lengths. However, Speedfit pipe, being flexible, can run from one fitting to another without having to install a connector in between.

Speedfit needs no jointing materials, eliminating the risk of fire from the use of a blowlamp, solder and flux

.

TRADITIONAL JOISTS

Instructions on the drilling of joists is given in the Building

Regulations Approved Document A, and summarised as follows:

1. Holes should be no greater than 0.25 of the depth of the joist.

2. Holes should be drilled at the neutral axis.

3. Holes should not be less than 3 diameters (centre to centre) apart.

4. Holes should be located between 0.25 and 0.4 times the span from the support.

Min 3 x hole dia.

D

Max. dia. of holes = 0.25D

TIMBER I BEAM JOISTS

Several types of joists are available and Speedfit recommends that specific manufacturers details are consulted.

However, the following can be used for general guidance.

• Holes may be located vertically anywhere in the web, but leave 3mm web at the top and/or bottom of hole.

Do not cut into joist flanges when cutting the web.

• If more than one hole is to be cut in the web, the distance between the edges of the holes must be at least 2x diameter of the largest hole.

• Generally joists are manufactured with 38mm perforated knockouts in the web at approximately

300mm centres along the length of the joist.

CROSS WEB JOISTS

Unlike I beam joists, pipe can be cabled anywhere within the open Web as no drilling is required. However, the top and bottom flanges must not be notched. Avoid damaging the outside diameter of the pipe as you cable through the metal cross web members

.

TIMBER FRAMED CONSTRUCTION

Speedfit is well suited for timber frame construction.

Ensure that the structural integrity is not compromised when installing the pipework.

If the pipe passes through an external wall, care must be taken not to damage the vapour barrier and should be installed on the inside of the thermal insulation layer.

If this is not possible, the use of conduit should be specified at the design stage.

STEEL FRAMED CONSTRUCTION

Speedfit is well suited for steel frame construction and care should be taken when installing the pipework.

All runs should be installed through preformed holes in the structure and protected by a rubber or plastic grommet.

Where clipping of pipework is restricted, cable ties may be used to secure the pipe.

As with all installations, make sure that any pipework passing through walls and floors does not affect the fire resistant properties of the structure.

DRY LINED WALLS

Speedfit pipework can be easily cabled through studwork and within wall systems as well as behind “dot and dab” plasterboard installations. Speedfit 10mm Barrier Pipe is most commonly used to feed radiators.

If incorporating fittings in this way, collet covers or collet clips must be used with the

Standard range of fittings.

WET PLASTER

To prevent surface damage to the plaster caused by expansion and contraction of Speedfit pipes, it is important to ensure that all Speedfit pipework is channelled into the wall and protected with appropriate sleeving. Alternatively, the pipework can be surface mounted and boxed in if required for aesthetic appearance.

LAYING OF PIPE IN CONCRETE AND MASONRY

Speedfit pipe and fittings can be laid in concrete and masonry providing they are installed in conduit pipe with access boxes for the fittings. As stated in Water

Regulation Schedule 2.7 and BS 8000 : Part 15, fittings and pipe should be removable for possible replacement.

Insulation is also recommended to protect against heat loss and the effects of frost.

Speedfit Conduit Pipe is supplied in either 15mm or 22mm in coil lengths of 25m or 50m. The flexible convoluted pipe has an outside diameter of 24mm and 30mm.

EXPOSED PIPEWORK

On long exposed runs of pipework, the expansion of

Speedfit pipe when warm (1% on length between 20 to

82°C) can cause it to sag between clip fixings. When this is undesirable, pipework can be boxed in or replaced with rigid copper pipe. Speedfit pipe and fittings are stabilised to withstand limited exposure to ultra-violet radiation in sunlight but are not designed for permanent direct exposure. Under such conditions painting or lagging is required. Pipe and fittings should also be lagged to prevent frost damage.

CHEMICAL EFFECTS

Only water or oil based paints should be used. Do not allow Speedfit fittings to come into contact with cellulose based paints, paint thinners or strippers, solder flux or acid based descalents or aggressive cleaning products. If there is a risk of any chemical treatments coming into contact with Speedfit, please contact the Technical Advisory

Service first to check compatibility.

FLUXES AND SPEEDFIT

JG Speedfit does not recommend that fluxes of any type come into contact with our pipe and fittings. However, if fluxes are to be used in an environment where Speedfit is installed then we recommend installers use non-acidic and zinc chloride free fluxes such as Fernox Flux.

ACOUSTIC

Properly installed, Speedfit pipes are virtually silent in operation and do not resonate; they absorb the acoustic vibrations and pressure waves created by cavitations, water hammer, float operated valve oscillation and other hydraulic effects. The inherent flexibility of Speedfit pipe effectively eliminates these troublesome problems, including those that occur when, due to thermal expansion, metal pipes rub against structural members and where long, straight runs of rigid pipe amplify water borne noise.

20

21

PROTECTION AGAINST RODENTS

When used in locations vulnerable to rodent attack, all plastic pipes and fittings should be adequately protected within sealed ducts.

Speedfit products along with other materials such as electrical cables may be damaged if rodents are present.

If vermin infestation is suspected then a rodent exterminator should take appropriate action

.

BIOLOGICAL

No taste, colour, odour or toxicity is imparted to water by

Speedfit components, nor do they promote microbiological growth.

In accordance with BS7291: Part 1 Clause 6.7, the opacity of both pipes and fittings allows insufficient light to pass for the growth of algae

Tests within the Water Regulations Advisory Scheme, have approved Speedfit pipe and fittings to BS 6920 for water quality.

SYSTEM TESTING

On completion of the plumbing and heating system it is essential that system checking and a hydraulic wet test takes place. Connections to boilers, radiators and sanitary ware should first be capped or plugged.

Testing should be carried out at

2 bar for 10 minutes followed by 10 bar for 10 minutes.

This testing combined with other relevant checks, should reveal most system problems. Any components within the system not designed to take these pressures should be disconnected.

Before carrying out a pressure test ensure all Speedfit pipe and fittings are installed correctly. Speedfit

Barrier Pipe is printed with insertion marks to help ensure full insertion has been achieved.

Remember pressure testing is NOT a substitute for making sure fittings are clean and free of any grit, dirt or swarf and the pipe is correctly inserted (see Making a

Good Connection, on page 06.

SYSTEM COMMISSIONING AND FLUSHING

With existing systems, flushing prior to the use of Speedfit is essential to remove any harmful contamination or chemical residues from elsewhere in the system.

For the installation of central heating systems flushing procedures must be in line with BS7593 code of practice for treatment of water in domestic hot water heating systems.

Flux residues used in the soldering of capillary fittings are very corrosive. Dirt and grit, which can enter the system when Speedfit pipe is being pushed through underfloor or across a roof space, must be removed.

During the commissioning of a heating system, all air must be removed from the system before the boiler is allowed to fire. This will ensure pockets of air do not cause localized overheating within the system as this could have a detrimental affect on the pipework and boiler.

For further advice on chemical flushing agents and inhibitor treatments, the following manufacturers should be contacted: Fernox Manufacturing Ltd., 01799 550811 or Sentinel Betz Dearborn Ltd., 0151 420 9595.

TECHNICAL ADVISORY SERVICE

The JG Speedfit Technical Advisory Service is available to assist and advise on all aspects of using the Speedfit system. The service is available between 8.00am and 4.30pm,

Monday to Friday on Telephone No. 01895 425333 and

Fax No. 01895 425350. Products within this Product Guide are designed for use within UK plumbing and heating installations or in other countries where similar installation requirements apply. For information on products suitable for use in other countries please consult our Technical

Advisory Service.

We take pride in the quality of our products and all complaints are investigated thoroughly. If you have a problem with a

Speedfit Product please return both fitting and pipe to us for investigation. We will need at least 50mm of pipe to ensure an accurate analysis. If there is a suspicion that the pipe is faulty, please provide marking details from the pipe.

COMMON PROBLEMS AND IDENTIFICATION

Problem:

Burst or melted pipe.

Pipe will be distorted showing either a ‘Parrot beak’ look or a long opening with the edges of the pipe melted in a wave shape.

Identification:

A ‘Parrot beak’ will have been formed by the pipe bursting due to the water freezing. If the Pipe has a melted appearance it will have been subject to a temperature in excess of 128 degrees Celsius. This will have been caused by direct contact with a heat source such as a blowtorch or flue pipe or by water or steam within the system rising above safety levels.

Problem:

A fitting or part of a fitting dissolved - the fitting may have blown off the pipe and may have missing component parts.

Identification:

The fitting will have failed because of a chemical attack. The most common attack is from acid based solder flux running down into the fitting during soldering of a nearby copper fitting or flux coming into contact with the fitting in some other way.

Problem:

Weep from fitting.

Identification :

The pipe has not been fully inserted up to the pipe stop or one or both of the ‘O’ rings have been damaged by burrs or sharp edges on the end of pipe. See

‘What Not to Do’ on page 06.

Problem:

The fitting has blown off the pipe. Fitting is missing the collet, the pipe insert is still inside the fitting after the pipe has come out.

Identification:

If this happens on first fix, the most likely reason is that the pipe has not been fully inserted into the fitting, up to the pipe stop, and the system has not been pressure tested.

If the collet (gripping device) is missing everything will blow out. If the collet is there and the pipe support is still inside the connector but the pipe has still blown out, this means that full insertion had not been accomplished.


The Speedfit Underfloor Heating System has been designed to be as quick and easy as possible to install with component parts manufactured to UK and European standards.

Underfloor heating provides the most comfortable even warmth of any heating system. It is economical to run and virtually maintenance free. The principle has been with us since

Roman times but is still the system of choice in some

European countries, accounting for 70% of installations.

The Speedfit System has water being pumped from a boiler to a pump pack, where it is mixed to approximately

50ºC then distributed via a manifold to heating circuits made using Speedfit Barrier Pipe. The pipe is laid in concrete or suspended just below the surface of the floor.

In concrete floors, the pipe is laid on insulation and then covered with a screed on which can be laid almost any type of floor covering.

For timber floors, spreader plates are laid between the joists and the floor decking or on the underside of the floor.

Speedfit Pipe is pushed into the grooves on the plates.

The floor area is typically warmed to between 25ºC and

28ºC, providing an even distribution of heat at only slightly higher than room temperature. The system is controlled by one or more thermostats which signal the Pump Pack when heat is required.

UNDERFLOOR HEATING SYSTEM

An Underfloor Heating System heats mainly by radiation.

Radiant energy is emitted by the floor giving an even distribution of heat. No cold spots, hot ceilings or cold feet.

The overall effectiveness of an UFH heating system can be seen below.

The heat is concentrated where it is most needed for comfort and efficiency.

RADIATOR SYSTEM AND HEAT GRADIENT

By contrast, radiators transfer heat from a relatively small area at a much higher temperature than the space being heated.

The radiator system heats mainly by convection. This results in the floor being the coolest place in the room, with the mass of warm air at ceiling level.

FEATURES & BENEFITS

The Speedfit Underfloor Heating System offers many benefits to the consumer. These include:

Installation

It is simple to install, requiring the minimum of installation effort and little maintenance.

Comfort

The system uses radiant heat, the most comfortable form of heating, to give a good even distribution of warmth over the whole room.

Space

The system in unobtrusive and space saving which means every square metre of floor and wall space can be fully utilised giving freedom of interior design.

Noise

Compared to radiator systems the system is virtually silent running.

Health

Dust is minimised reducing the problem of house dust mites. Reduced numbers of hot surfaces and sharp edges minimise risk of burns or injury.

Economic

Underfloor Heating Systems are designed to operate at lower temperatures than radiator systems, resulting in reduced energy consumption and lower heatloss from the building structure.

Control

The system is easy to control and the small temperature difference between the floor and air means the system is virtually self - regulating.

Environment

Underfloor heating is suitable for use with the most energy efficient and environmentally friendly heating systems including condensing boilers, solar power and heat pumps.

FLOOR FINISHES AND COVERING

The Speedfit Underfloor Heating System is suitable for most floor finishes, including ceramic tiles, carpets, vinyl and laminate.

The thermal resistance of floor covering will have a marked effect on the performance of the heating system.

Advice on the use of floor coverings and their effect on the performance of a system is laid out in the Speedfit

Underfloor Heating Manual.

The control unit has integral ball valves to allow for isolation from the primary heating system, an adjustable blending valve and a 6 metre head circulation pump. An anti-vibration mounting bracket ensures silent operation.

Speedfit push in connections make for a fast connection to pipework.

Speedfit recommend connection to the main central heating flow and return distribution system, but it is also possible to connect to the nearest radiator supply pipe.

A full and detailed installation guide is provided with each unit.

The Speedfit Underfloor Heating Control Unit is suitable for use when:

• The boiler serving the existing heating system has the capacity to take the extra output from 2KW to 3KW

• The boiler is compatible with the additional pump

• The maximum area to be heated is 30 sq metres

The Control Unit is designed to be used with Speedfit

Barrier Pipe. The amount of pipe needed is determined not only by the size and shape of the room but by the resistance of the floor finish to heat transfer.

INSTALLATION IS QUICK AND EASY

SOLID FLOOR INSTALLATIONS

SCREEDS

The screed is an important and integral part of the UFH system, transferring energy from the pipes to the area to be heated. The response of this ‘thermal mass’ will depend on its depth and make up.

The usual depth of screed is 65 - 75mm thick but it is possible depths can be reduced to assist in improving performance.

PIPE LAYOUT IN SOLID FLOOR INSTALLATIONS

The shape of the room and the position of the outside walls and windows will determine the pattern of the pipe layout. The counterflow pattern is recommended although other options are shown below.

Single Serpentine Double Serpentine

Triple Serpentine Counterflow

The floor is cleared of dust and debris and insulation is laid across the area.

TIMBER FLOOR INSTALLATIONS

Spreader plates are available for timber flooring which uses either traditional joists or TJI joists.

Speedfit Pipe is laid in a pre-determined pattern and fixed in position with staples.

Fit the Speedfit Manifold to the wall and connect the

Pump Pack.

Connect the ends of the pipes to the Manifold.

Spreader plates 390mm x

1,000mm and 390mm x

250mm are designed for use with traditional joists at 400mm centres. They are laid across the joists and fixed in place using a hand stapler. The 15mm

Speedfit Pipe is pushed into the grooves in the plate and the floor decking laid on top.

Insulation can be placed between joists to the underside of the plates either before or after the plates have been laid.

The system is filled and pressure tested.

The screed should be laid whilst the pipe is pressurised.

The underfloor heating system should not be used to dry the concrete screed.

Spreader plates 165mm x

1000mm can be used with either traditional or

TJI joists and with the floor already in place.

They are fixed to the underside of the floor using staples or screws.

The Speedfit Pipe is fixed in to the groove.

When the plates and pipework have been installed, the insulation is placed in the floor void to minimise downward heat loss.

• Concrete and masonry.

Speedfit pipe and fittings can be laid in concrete and masonry providing they are installed in conduit pipe with access boxes for the fittings. This is to enable the pipe to expand and provide accessibility for both pipe and fittings. As stated in Water Regulation Scheme 2.7 and BS

8000 : Part 15, fittings and pipe should be removable for possible replacement.

Insulation is also recommended to protect against heat loss and the effects of frost.

• Electrical continuity.

If Speedfit is used in an existing metal system which may have been used for earthing, electrical continuity should be reinstated.

• Valves and taps.

Plastic 15mm and 22mm valves and taps available from

JG Speedfit Ltd are not suitable for central heating installations.

• High temperatures.

Can withstand 114°C intermittently for short periods.

The Speedfit system should not be used on an uncontrolled heat source.

• Insulation.

Should comply with BS6700 and BS5422, as for copper.

• Collet Covers.

Collet covers provide added security against pipe disconnection, e.g. the fittings coming into contact with rigid surfaces and behind dry-lining walls. They are offered in white as standard and in red or blue to provide colour coding of pipe.

• Minimum bend radii (PEX)

• System testing.

To ensure the pipework and fittings have been installed correctly, whether it be on a new or extended system, it is essential that the system is checked and hydraulically wet tested. Testing should be at 2 bar for 10 minutes and 10 bar for 10 minutes. This testing, combined with other relevant checks, should reveal installation problems and is regarded as good plumbing practice. However, system testing should not be regarded as a substitute for correct installation (see also “Making a Good Connection”).

• System flushing.

As is usual practice for any plumbing installation, flushing of the system prior to the use of Speedfit is recommended to remove any contaminants/ chemical residue from elsewhere in the system.

28mm 800mm 1,000mm

Where pipe is concealed, clipping may only be required where necessary.

• British Gas Service has accepted the John Guest Speedfit fittings as being suitable for open vented and sealed central heating systems and as eligible for acceptance onto its service contracts.

• Vermin.

Speedfit products will need special protection in vermin infested areas.

• Expansion (PEX pipe).

BetzDearborn Limited on 0151 420 9595.

• Maximum Torque figures (BSP & BSPT).

Plastic threads are not generally as strong as brass threads. Customers and end users should be aware of this when choosing products for their applications. Overtightening of plastic threads will cause undue stress and eventual cracking and leakage. The maximum torque figures for BSP and BSPT threads used on Speedfit plumbing products in mating threads conforming to the relevant BS or International thread standards are shown below.

• Paint and Chemicals.

Use only water or oil based paint. Collet covers prevent paint ingress into fittings. DO NOT ALLOW CONTACT WITH oil based jointing compounds, cellulose based paints, paint thinners, paint strippers, solder flux, acid based descalents or aggressive cleaning products.

• Solder Flux.

No fluxes of any types should come into contact with

JG Speedfit Pipe and Fittings. If fluxes are to be used in an environment where Speedfit is installed, then (1) extreme care should be taken to ensure that no such contact takes place and (2) JG recommend installers only use fluxes tested and approved in writing in advance by JG. At the date of this publication, the only such approved flux is Fernox Flux.

• Collet Clips. White and Grey collet clips are used with standard fittings to prevent accidental pipe disconnection. Red or blue clips provide colour coding of pipe. Red and blue clips should not be used to prevent accidental release of pipe.

• Pre-Screed System Testing. To ensure the pipework has been installed correctly and prior to the screed being laid, it is essential that the system is checked and hydraulically wet tested.

Testing should be carried out at 2 bar for 10 minutes and 10 bar for

10 minutes.

This testing, combined with other relevant checks, should reveal installation problems and is regarded as good plumbing practice.

• Pressurisation During Screed Laying & Curing. In accordance with

BS1264-4, the system should be left under pressure at a minimum of 6 bar for the duration of the laying and curing of the screed.

Under NO circumstances should the UFH System be used to quicken the screed drying process.

• System Flushing.

As is usual practice for any plumbing installation, flushing of the system prior to the use of JG Speedfit is recommended to remove any contaminants/chemical residue from elsewhere in the system.

• Vermin.

Speedfit products should not be used in vermin infested areas.

• Frost Protection.

During the installation process it is important that pipe containing water be protected from frost.
