Appliance Introduction

The F30E and F35 E boilers are wall mounted modulating boilers with electronic ignition providing central heating and hot water. The F30E SB boiler is wall mounted modulating boiler with electronic ignition providing central heating only.

The boiler is of the II as distributed in the United Kingdom, or Butane (G30), Propane (G31) with the appropriate conversion kit.

The boiler has a fan assisted balanced flue which both discharges the products of combustion to and draws the combustion air from the outside of the room. The central heating and domestic hot water (F30E/F35E only) temperatures are user adjustable. Domestic hot water demand (F30E/F35E only) always has priority over heating demand. The boiler is designed for use as part of a sealed water central heating system with fully pumped circulation. The pump, expansion vessel and associated safety devices are all fitted within the boiler. The boiler can be installed against either an external wall or on an adjacent inside wall, that is, the flue system will pass directly

The installation of the boiler must comply with the requirements of the current issue of BS6798, in Ireland, refer also to the current edition of I.S.813"Domestic Gas Installations".

In GB it is necessary to comply with the Water Supply (Water Fittings) Regulations 1999 (for Scotland, the Water Byelaws 2000, Scotland).

To comply with the Water Regulations your attention is drawn to: The Water Regulations guide published by the Water Regulation Advisory Service (WRAS) which gives full details of the requirements.

In IE the requirements given in the current edition of I.S.813 "Domestic Gas Installations" and the current Building Regulations must be followed.

• The Themaclassic F is for use with sealed central heating systems.

• Heating surfaces may consist of radiators, convectors or fan assisted convectors.

• The safety valve is an integral part of the boiler and it cannot be adjusted.

• The circulation pump is integral with the boiler.

• Pipe sectional areas shall be determined in accordance with normal practices, using the output/pressure curve (diagram 3.1). The distribution system shall be calculated in accordance with the output requirements of the actual system, not the maximum output of the boiler. However, provision shall be made to ensure sufficient flow so that the temperature difference between the flow and return pipes be less than or equal to 20°C. The minimum flow rate is shown in table 1.

Diagram 3.1

• The system can be fitted with a lockable control valve if necessary in the main flow or return pipes shown as valve 'A'

in diagram 3.2.

• The piping system shall be routed so as to avoid any air pockets and facilitate permanent venting of the installation. Bleed fittings must be provided at every high point of the system and on all radiators.

• The total volume of water permitted for the heating system depends, amongst other things, on the static head in the cold condition. The expansion vessel on the boiler is pressurised at

0.5 bar and allows a maximum system volume of 156 litres for an average temperature of 75°C and a maximum service pressure of 3 bar. This pressure setting can be modified at commissioning stage if the static head differs. An additional expansion vessel can be fitted to the system if required, see

diagram 3.2.

Guidance on vessel sizing is also given in a current issue of a BS5449 and BS7074 Part 1, for IE refer to the current edition of I.S.813 "Domestic Gas Installations".

• Provision shall be made for a drain valve at the lowest point of the system.

• Where thermostatic radiator valves are fitted, not all radiators must be fitted with this type of valve, and in particular, where a room thermostat is installed.

• In the case of an existing installation, it is ESSENTIAL that the system is thoroughly flushed prior to installing the new boiler, using a proprietary product from Fernox or Sentinel.

4 Domestic Hot Water System Design. F30E and F35E Only

General - All domestic hot water circuits, connections, fittings

must be in accordance with the relevant standards and water supply regulations.

For GB: Guidance G17 to G24 and recommendation R17 to R24 of the Water Regulation Guide.

For IE: The current edition of I.S.813 "Domestic Gas Installations".

• Copper tubing or plastic Hep hot water system. Unnecessary pressure losses should be avoided.

• Provision shall be made for a drain valve at the lowest points of the system.

0 may be used for the domestic

• The flow restrictor, supplied in the document envelope, must be fitted as diagram 7.1, limiting the flow through the boiler to a maximum of 12 litres/min for F 30 E and 14 litres/min for F 35 E.

• The boiler will operate with a minimum supply pressure of 0.5 bar, at a reduced flow rate.

Best operating performance will be obtained from a supply pressure of 1 bar or greater.

4.1 Hard Water Areas

In areas where the water is 'hard', more than 200mg/litre, it is recommended that a proprietary scale reducer is fitted in the cold water supply to the boiler.

6 Boiler Location, Flue and Ventilation

6.1 Boiler Location

The recommended clearances are shown in diagram 6.1. Note: The boiler must be mounted on a flat wall which is

sufficiently robust to take its weight when full. If in doubt, expert advice should be obtained.

The minimum acceptable spacings from the terminal to obstructions and ventilation openings are shown in diagram

6.2. For Ireland the minimum distances for the flue terminal positionning must be those detailed in I.S.813 "Domestic Gas Installations".

The boiler must be installed so that the terminal is exposed to the external air.

6.2 Terminal guard, see diagram 6.3.

A terminal guard is required if persons could come into contact with the terminal or the terminal could be subject to damage.

If a terminal guard is required, it must be positioned to provide a minimum of 50mm clearance from any part of the terminal and to be central over the terminal.

A suitable terminal guard type K3 can be supplied by:

8 Boiler Preparation and System Connections

8.1 Cutting the flue hole

• Remove the wall template, follow the instructions given on the wall template.

• Position the wall template, taking due regard of the minimum clearances for the selected flue application, see diagram 8.1.

• Horizontal Rear hole cutting

• Mark position of Rear flue outlet hole from template, then remove template, before cutting, for use, later. The core drill used should be 115 mm diameter.

• Top Outlet Side / Rear hole cutting

• Mark the centre line for the hole on the wall. Extend the horizontal centre line to the side wall if required and mark the vertical centre line of the hole as shown in diagram 8.1.

• Making allowance for the slope of the flue, cut hole in wall, preferably using a core drill. For installations with internal and external access use a 105mm diameter core drill. For installations with only internal access use a 125mm diameter core drill.

IMPORTANT NOTE: When cutting the flue hole and when extending the flue centre line to a side wall, remember that the flue system must have a fall of about 35mm per metre of flue downward towards the terminal. There MUST never be a downward incline towards the boiler.

Note: If the appliance is not to be fitted for some time, cover the hole in the wall.

145

8.2 Rear Flue - Internal Installation Only

Refer to "Horizontal Rear Flue" instructions, section 10 and prepare the flue system. Insert the flue system into the hole such that it will not interfere with the appliance when lifting into position.

8.3 Fixing jig, refer to diagram 7.1

• IMPORTANT NOTE: Ensure that the hanging bracket is fitted to a flat and true wall area for correct alignment with the boiler.

Side Flue - Check the horizontal centre line and reposition the template if necessary.

Rear Flue - Reposition the wall template over the hole in wall.

• Mark the securing position holes.

• Check that the hanging bracket is level.

• Drill, plug and secure the bracket to the wall, using suitable screws (not supplied) for the wall type and capable of supporting the total weight of the appliance (refer to wall template for fixing points).

8.4 Water connection

IMPORTANT NOTE: Do not subject the isolating valves to heat

from blowlamp, when making connection.
