The SFUTS version is pre-wired and pre-plumbed and is simple to install. See page 5 for a

description of this.

Follow the layouts carefully, the pumped solid fuel pipe-set is assembled and supplied packed

with SFUTS. It should be attached to the store. If this is not possible it should be less than one

metre from the store. Full fitting instructions are supplied with this pipe set.

Gravity flow is important in case of power cuts etc. Gravity flow is normally achieved by putting

the thermal store level or higher than the stove. If this can't be achieved a wood burner with a

quench pipe must be installed in case of overheat.

Set the boiler thermostat to 75°C. Set the solid fuel thermostat to 80°C. This will help

increase the energy stored in the unit and reduce reliance on fossil fuel. Solar thermal can

also operate at 80°C. Boilers must have over-temperature protection and must be able to

supply temperatures of at least 75°C. A zone value and by-pass may be necessary for boilers

with pump over run if the store temperature is reduced by more than 3°C.

In high risk installations (care homes, nurseries etc.) care should be taken to reduce central

heating temperatures with a blending valve. Underfloor heating should be routed through a

control manifold. Nuisance gravity circulation should be minimised using either zone valves

or anti-gravity valves.

In order to comply with Part L Building Regulations it is necessary to insulate any hot water

(primary and secondary) pipework within one metre of the cylinder. Guidance is given in the

Table 5 (Page 20) of the 2013 Domestic Heating Compliance guide. Insulation values for the

most popular pipe sizes are reproduced below.

Pipe outside diameter

Note:All joints must be tested as they can loosen in transit.

HOT WATER

If hardness exceeds 200ppm, use a treatment to soften water.

Scale build-up can happen rapidly and reduce flow and efficiency.

Always flush after commissioning but DO NOT USE heavily chlorinated solutions unless you are

prepared to thoroughly flush the whole heating system after heat up and cool down.

If flow is poor check incoming water supply and make sure all valves etc. are fully open.

If temperature is poor check that the store has reached 75°C and that the blending valve is set

at the appropriate temperature.

Use inhibitor in heating systems. Remember to include the store volume when dosing.
