1.10 WATER CIRCULATION SYSTEM

IMPORTANT:

A minimum length of 1 metre of copper

pipe MUST be tted to both ow and return connections from

the boiler before connection to any plastic piping.

The central heating system should be in accordance with

BS6798 and, in addition, for smallbore and microbore systems,

BS5449.

Water treatment is covered later in these instructions.

Refer to Section

1.17

1.11 BOILER CONTROLS

System controls should be installed to ensure the boiler has

no demand when there is no requirement from the system, in

compliance with Building Regulations.

Heating systems utilising full thermostatic radiator valve control

of temperature in individual rooms should also be tted with a

room thermostat controlling the temperature in a space served

by radiators not tted 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 tted with an automatic bypass

valve to ensure a ow of water should all valves be in the

closed position.

1.12 ELECTRICALSUPPLY

WARNING: This appliance must be earthed

Wiring external to the appliance MUST be in accordance with

the current I.E.E. (BS7671) Wiring Regulations and any local

regulations which apply.

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.

1.13 CONDENSATE DRAIN

The condensate drain provided must be connected to the

drainage point on site. All condensate drainage pipework and

ttings must be made of plastic.

IMPORTANT: The condensate drain pipework should

be installed in accordance with BS6798.

The drain outlet on the boiler is sized for standard 21.5 mm

overow pipe. It is a universal tting to allow use of di󰀨erent

brands of pipework.

Refer to Section

2.15

1.8 AIR SUPPLY

It is not necessary to have an air vent in the room or internal

space where the boiler is installed.

1.9 GAS SUPPLY

Consult the local gas supplier to establish an adequate supply

of gas. Do not use existing service pipes without consulting the

local gas supplier.

The gas supply must be governed with a meter.

A gas meter can only be connected by the local gas supplier or

by a Gas Safe Registered Engineer.

An existing meter should be checked, preferably by the gas

supplier, to ensure that the meter is adequate to deal with the

required gas supply rate.

It is the responsibility of the Gas Installer to size the gas

installation pipework in accordance with BS6891.

Whilst the principle of the 1:1 gas valve ensures the Logic

range is able to deliver it is full output at inlet pressures as low

as 14 mb, other gas appliances in the property may not be as

tolerant. When operating pressures are found to be below the

minimum meter outlet of 19 mb these should be checked to

ensure this is adequate for correct and safe operation.

Allowing for the acceptable pressure loss of 1mb across the

installation pipework, it can be assumed that a minimum

permitted operating pressure of 18mb will be delivered to the

inlet of the appliance.

(Reference BS6400-1 Clause 6.2 Pressure Absorption).

The external gas cock could further reduce the operating

pressure when measured at its test point. The pressure drop

is relative to the heat input to the boiler (kW), refer to graph

below.

IMPORTANT:

Ensure all gas valve connections are

gas tight with a gas soundness check up to the gas control

valve.

Installation pipes must be tted in accordance with BS6891.

The complete installation MUST be tested for gas tightness

and purged as described, for the majority of installations the

appropriate standard is IGEM/UP/1B [23], but alternatively

IGEM/UP/1 [21] or IGEM/UP/1A [22], as appropriate, can be

utilized.
