INSTALLATION

WATER CONNECTIONS

effective circulation can occur around the primary circuit to carry heat away and thus stop boiling.

Heating systems

The size of the heating system which can be run, will depend on the output rating of the appliance. It will be necessary to work out heat loss calculations for the system proposed in order to establish the kW/hr rating. An appliance that will meet this figure can then be chosen; (for boiler outputs please refer to the brochure).

The constructional requirements of installing and connecting the appliance also need to be taken into account when selecting. Design and calculations for individual heating systems should be carried out by a qualified heating engineer. In many cases your supplier will be able to offer advice and assistance.

Direct Systems

Stainless steel boilers, either factory fitted or retro-fitted as add-in boilers enable connection to direct systems to be made without the need to change the cylinder or to fit an expansion tank.

This applies to domestic water supply only and should not be done when in an area with soft water.

If radiators are used then an indirect system must be utilised.

To connect the cylinder use 28mm copper pipes. Ensure that the pipes rise continuously to the cylinder.

Ensure that the runs are not too long, i.e. 20ft maximum each for flow and return. Install the cylinder above the level of the fire, and as close to it as possible. (the higher the cylinder the faster the circulation). Ensure that no valves are present in the circulating pipes.

Indirect Systems - The Domestic Hot Water Circuit

In addition to providing hot water the primary circuit is essential in providing a "heat leak" to absorb excessive heat produced in the event of the circulation pump shutting down.

Heat is produced in varying quantities while the fire is alight and care must be taken to ensure that

The output of any radiator installed as a "heat leak" should not be less than 10% of the rated output of the appliance. The radiator should not be fitted with a control valve.

The cylinder must be of the indirect type with a minimum capacity of 110 litres, conforming to BS 1566 part 1.

Primary flow and return pipes should be 28mm diameter. The cylinder should be installed at a higher level than the appliance, and as close to it as possible (the higher the cylinder the faster the circulation). The flow and return pipes should not be longer than 20ft each. Pipe runs should rise continually from the boiler to the cylinder.

A radiator of approximately 25 sq.ft. should be connected into the primary circuit, if installed in the bathroom it provides a means of drying towels in the summer.

Safety Vent Circuit

This circuit consists of a cold feed pipe, expansion pipe, and expansion tank. The possibility that water may boil can never be completely ruled out, and it is therefore vital to ensure that cold water can be supplied to the boiler and steam vented from it at all times.

The expansion tank should have a capacity of at least 7 % of the system's water capacity. The cold water feed pipe should be at least 22mm diameter.

There must not be any shut off valves in the circuit. Pipes should be run to avoid air locks. A safety relief valve should be fitted to the expansion pipe close to the boiler.

It is often possible, and is good practice, to utilise the primary flow and return as part of the safety circuit. The ball valve should have a copper ball. The overflow pipe from the expansion tank should be 28mm diameter copper. Pipes in unheated

spaces must be lagged.

Stratford Tf, Stratford Ti specifications

Aarrow Fires is renowned for its innovative and high-quality heating solutions, particularly the Stratford Ti and Stratford Tf models. These contemporary wood-burning stoves combine advanced technology with aesthetic appeal, making them excellent choices for both functionality and style in any home.

The Stratford Ti model is distinguished by its sleek design and robust construction. It features a large glass window that provides an unobstructed view of the burning flames, creating a warm and inviting atmosphere. One of the standout characteristics of the Stratford Ti is its efficiency. With an impressive efficiency rating, this stove ensures that more heat is generated from every log used, which means less frequent reloading and better fuel economy. The air wash system helps to keep the glass clean, maximizing the visual experience and reducing maintenance.

The Stratford Tf, on the other hand, is an equally impressive model with unique features that cater to diverse heating needs. It is designed with a wider firebox, allowing for larger logs and longer burn times. This characteristic makes it ideal for those who prefer a more extended heating experience without the need for constant refueling. The Stratford Tf also incorporates Aarrow's primary and secondary air controls, which provide users with greater control over the burn rate and heat output.

Both models employ cutting-edge technologies, including a sophisticated combustion system. This system ensures that fuel is consumed efficiently, resulting in fewer emissions and enhanced environmental performance. The stoves meet stringent eco-friendly standards, making them a sustainable choice for modern homes.

In terms of aesthetics, the Stratford Ti and Tf models excel with a variety of finishes and options, including traditional and contemporary styles. Whether placed in a rustic cabin or a modern apartment, these stoves complement any interior decor.

Safety is another priority for Aarrow Fires, as both stoves are designed with robust features to ensure safe operation. Built-in heat shields and proper airflow designs help minimize the risk of overheating and ensure that the surrounding areas remain cool to the touch.

In summary, the Aarrow Fires Stratford Ti and Tf models represent the best in wood-burning stove technology. With their impressive efficiency, stunning design, and user-friendly features, these stoves are perfect for anyone seeking a reliable heating solution that adds value and warmth to their living space.
