Installation and Servicing

general

 

2.

  It is important that the position of the terminal allows the free 

passage of air across it at all times.

3.

  Minimum acceptable spacing from the terminal to obstructions 

and ventilation openings are specified in  

Table 4.

4.

  Where the lowest part of the terminal is fitted less than 2m 

(6’6”) above a balcony, above ground or above a flat roof 

to which people have access then the terminal MUST be 

protected by a purpose designed guard.  

  Terminal guards are available from boiler suppliers. (Ask for 

TFC flue guard model no. K6 - round, plastic coated). In case 

of difficulty contact:

  TFC Group. 

Tel. + 44 (0) 01732 351 680 

Tower House, Vale Rise 

Fax. + 44 (0) 01732 354 445 

Tonbridge. Kent TN9 1TB 

www.tfc-group.co.uk

  Ensure that the guard is fitted centrally.

5.

  The flue assembly shall be so placed or shielded as to prevent 

ignition or damage to any part of any building.

6.

  The air inlet/products outlet duct and the terminal of the boiler 

MUST NOT be closer than 25mm (1”) to combustible material. 

Detailed recommendations on the protection of combustible 

material are given in BS. 5440-1:2008.

IMpORTaNT

. It is essential to ensure, in practice, that products 

of combustion discharging from the terminal cannot re-enter the 

building or buildings through any openings into the building such 

as ventilators, windows, doors, or other sources of natural air 

infiltration, such as forced ventilation openings etc.
If products of combustion re-entry is identified or suspected this 

should be immediately investigated and corrected following the 

guidance provided in the current Gas Industry Unsafe Situation 

Procedure.

TERMINaL

The terminal assembly can be adapted to accommodate various 

wall thicknesses. Refer to Frame 1 .

aIR sUppLy

It is NOT necessary to have a purpose-provided air vent in the 

room or internal space in which the boiler is installed. Neither is 

it necessary to ventilate a cupboard or compartment in which the 

boiler is installed, due to the low surface temperatures of the boiler 

casing during operation; therefore the requirements of BS 6798, 

Clause 12, and BS 5440:2 may be disregarded.

WaTER CIRCULaTION sysTEM

IMpORTaNT.

 

A minimum length of 1 metre of copper pipe MUST be fitted to 

both flow and return connections from the boiler before connection 

to any plastic piping.
The central heating system should be in accordance with BS.6798 

and, in addition, for smallbore and microbore systems, BS.5449.

WaTER TREaTMENT - see Frame 5

BOILER CONTROL INTERLOCKs

Central heating systems controls should be installed to ensure 

the boiler is switched off when there is no demand for heating, in 

compliance with Building Regulations.
Heating systems utilising full thermostatic radiator valve control 

of temperature in individual rooms should also be fitted with a 

room thermostat controlling the temperature in a space served by 

radiators not fitted with such a valve.
When thermostatic radiator valves are used, the space heating 

temperature control over a living / dining area or hallway having 

a heating requirement of at least 10% of the minimum boiler heat 

output should be achieved using a room thermostat, whilst other 

rooms are individually controlled by thermostatic radiator valves.  

However, if the system employs thermostatic radiator valves on all 

radiators, or two port valves, then a bypass circuit must be fitted 

with an automatic bypass valve to ensure a flow of water should 

all valves be in the closed position.

ELECTRICaL sUppLy

Warning.

 

This appliance must be earthed. 

Wiring external to the appliance MUST be in accordance with 

the current I.E.E. (BS.7671) Wiring Regulations and any local 

regulations which apply. For IE reference should be made to the 

current ETCI rules for electrical installations.
The mains supply to the boiler and system wiring centre shall 

be through one common fused double pole isolator and for new 

heating systems, and where practical replacement installations, 

the isolator shall be situated adjacent to the appliance.

CONDENsaTE DRaIN  

(Refer to Frames 22, 23 & 40

)

A condensate drain is provided on the boiler. This drain must be 

connected to a drainage point on site. All pipework and fittings in 

the condensate drainage system MUST be made of plastic - 

no 

other materials may be used.

IMpORTaNT.

Any external runs must be in accordance with BS 6798.
The drain outlet on the boiler is sized for standard 21.5mm (3/4”) 

overflow pipe.  It is a universal fitting to allow use of different 

brands of pipework.

* Only one reduction down to 25mm is allowable per installation 

  otherwise BS5440-1 2008 dimensions must be followed.
