1. Introduction

The Advance unvented water heater is a high quality stainless steel unvented cylinder to provide hot water from a cold mains water supply of between 3 bar and 16 bar.

Reduced performance is available at lower pressures although the units are not suitable for pressures lower than 1.5 bar and a flow rate of less than 20 litres per minute. The indirect heat exchange surfaces are designed to provide a rapid heat up time. The unit comes complete with all the necessary safety equipment to comply with legislation governing the installation of such systems. The Advance solar unvented water heater has been designed for use with all solar panels and for heat pump systems a special range is available.

The unit can be placed anywhere convenient. Since it is connected directly to the mains water supply it is equally efficient on any floor – ground, first or second. Avoid areas that may be subject to frost. Try to keep pipe runs as short as possible for maximum economy, especially hot water discharge pipes running down from the

Advance unit.

Cold Water Valve

The combined cold water valve

(supplied) can be connected anywhere on the cold water mains prior to the unit. It can be located at a point near to where the mains supply enters the premises if this is more convenient.

When installing the cold water valve,

The motorised valve supplied and the thermal cut-out (Hi limit stat) must be fitted to the primary flow

(Use compression fittings only).

Operation of the cut-out and motorised valve; to comply with regulations and to prevent the temperature reaching 100°C the thermal cut-out supplied must be fitted.

Two Port Valve

The two port valve should be wired to the thermostat

(see Fig 8 or 9) depending on required configuration.

Connect the live supply to the thermal cut-out and connect the brown wire of the two port valve to terminal 2 on the thermosta. Earth and Neutral supplies can be connected directly to the valve.

The thermal cut-out is wired in series to the cylinder thermostat. When the thermal cut-out senses an abnormalrise in temperature in the primary flow the electrical supply to the motorised valve will be cut, and the valve will bein the closed position thus cutting off the primary water from the boiler to the indirect coil in the cylinder. If this occurs it must be reset manually.

The orange wire of the two port valve should be connected to the central heating boiler and the cylinder thermostat set to 60°C.

The power supply to the pump station should be connected via the lower valve.

If the thermal cut-out operates check the cylinder stat and or boiler stat.

2.4

Tundish

Tundish

The tundish supplied must be fitted so it is visible to the occupie. The discharge pipe must be 22mm copper pipe. Regulations do not permit more than

3 x 90 - degree bends between the Advance unit and the outflow. Between the temperature & pressure relief valve and the first 90-degree bend there must be a fall of at least 300mm. The fall of the pipework must be continuous and the pipe should terminate in the gully or be bent backwards onto an outside wall, in a place where discharge cannot be injurious to persons.

External Expansion Vessel

This smaller tank is connected to the cold-water inlet side of the vessel. Mount the tank according to separate manufacturers instructions provided with the External Expansion vessel (see Fig 7).

A suitable expansion vessel with a pre-charge pressure of 3.5 bar is supplied with the Advance solar.

If you need to site the Advance unit in the middle of the house your discharge pipe to the tundish can be as far away as 9m, which in most cases is enough to run the final discharge point. After 9m, increase the pipe size to a greater diameter than

22mm and accordingly for subsequent 9m lengths,

(Table 1).

The expansion vessel should be Tee’d off between the pressure relief valve and the cylinder

(see installation diagram) and should always be positioned with the entry point at the bottom

Installation should always be by means of a standard T connector ensuring no other valve is between this and the cylinder. Adjust the pressure to 3.5 bar.

2.4

Tundish (Continued)

Scale

In hard water areas lower water temperatures can result in less scale being deposited.

If a water softener is used it should be capable of flows of approximately. 50 lt/min, this will maintain maximum performance of the Advance unit. If no descaler or softener is used then the heating element(s) will need descaling periodically for maximum efficiency and to prevent damage.

(Fig. 11) Tundish Installation

IMPORTANT: Regular checks should be carried out to ensure that the expansion vessel is correctly pressurised to 3.5 bar at all times.

2.5

Discharge Pipework

G3 Guidance Section 3.5

The discharge pipe (D1) from the vessel up to and including tundish is generally supplied by the manufacturer of the hot the installation should include the discharge pipe(s) (D1) from the safety device(s). In either case the tundish should be vertical, located in the same place as the unvented hot water storage system and be fitted as close as possible to, and lower than, the safety device, with no more than 600mm of pipe between the valve outlet and the tundish

The discharge pipe (D2) should be made of:

a. metal; or

The discharge pipe (D2)

The discharge pipe (D2) from the tundish should:

a. have a vertical section of pipe at least 300mm long below the tundish before any elbows or bends in the pipework (see Fig. 12); and

b. be installed with a continuous fall of at least 1 in 200 thereafter.

b. other material that has been demonstrated to be capable of safely withstanding temperatures of the water discharged and is clearly and permanently marked to identify the product and performance standard

(e.g. as specified in the relevant part of BS 7291-1:2006 Thermostatic pipes and fittings for hot and cold water for domestic purposes and heating installations in buildings,

General Requirements).

2.5

Discharge Pipework (Continued)

Termination of Discharge Pipe Sizing

The discharge pipe (D2) from the undish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge.

Examples of acceptable discharge arrangements are: a. to a trapped gully with the end of the pipe below a fixed grating and above the water seal; b. downward discharges at low level; i.e. up to 100mm above external surfaces such as car parks, hard standings, grassed areas etc. are acceptable providing that a wire cage or similar guard is positioned to prevent contact, whilst maintaining visibility; and, c. discharges at high level: e .g . into a metal hopper and metal downpipe with the end of the discharge pipe clearly visible or onto a roof capable of withstanding high temperature discharges of water and 3m from any plastic guttering system that would collect such discharges .

The discharge would consist of high temperature water and steam roofing felt and non-metallic rainwater goods may be damaged by such. Asphalt, discharges.

.

Worked Example of Discharge Pipe Sizing

The example below is for a G

1/2 temperature relief valve with a discharge pipe (D2) having 4 No elbows and length of 7m from the tundish to the point of discharge. From table 1:

(overleaf)

Maximum resistance allowed for a straight length of 22mm copper discharge pipe (D2) from G

1/2 the resistance for 4 No 22mm elbows at 0. 8m each = 3 .2m, therefore the permitted length equates to 5.8m. This is less than the actual length of 7m

Maximum resistance allowed for a straight length of 28mm pipe (D2) from a G

1 /2

temperature relief valve equates to 18m Subtract the resistance of 4 No

28mm elbows at 1m each = 4m .

Therefore the maximum permitted length equates to 14m As the actual length is 7m a 28mm (D2) copper pipe will be satisfactory.

(Fig. 12) Typical discharge pipe arrangement

IMPORTANT: The discharge will consist of scalding water and steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges.

Safety Checks

Any water coming from either the expansion relief valve or the temperature / pressure relief valve during heat up is indicative of a problem which needs to be identified and rectified. The temperature relief and expansion relief valves should be fully opened, one at a time then both together allowing as much water as possible to flow through the tundish .

Check that your discharge pipework is free from debris and is carrying the water away without spillage over the tundish and release the valves and
