Installation and Servicing

Section 1 - General

1.1 INTRODUCTION

The Logic Combi2range of boilers are wall mounted,

condensing, combination gas boilers.

Features:

• High e󰀩ciency

• Full sequence

• Automatic spark ignition

• Low water content

• Fanned ue

The boiler is supplied fully assembled with DHW plate heat

exchanger, diverter valve, circulating pump, pressure gauge,

PRV and CH expansion vessel.

Variable CH and DHW temperature controls are tted on the

user control and the boiler features a DHW preheat facility.

The boiler includes as standard:

- Automatic bypass

- Boiler frost protection

- Daily pump and diverter valve exercise.

The boiler casing is of white painted mild steel with a white

polymer front panel.

The boiler temperature controls are visibly located in the

control panel on the front of the boiler.

The heat exchanger is manufactured from cast aluminium.

The boiler is suitable for connection to fully pumped,

sealed heating systems ONLY. Adequate arrangements for

completely draining the system by provision of drain cocks

MUST be provided in the installation pipework.

Pipework from the boiler is routed downwards.

A PRV grommet is tted to the boiler which requires the

correct tting and securing of a clip (supplied) to ensure safe

discharge of the PRV should this occur.

Data Plate

The boiler model and serial number can be located on the

bottom of the boiler casing, shown in Section 1.13 - Water &

Gas Connection Diagram.

Refer to Section

1.13

1.2 OPERATION

With no demand for CH, the boiler res only when DHW is

drawn o󰀨, or periodically for a few seconds without any DHW

draw-o󰀨, in order to maintain the DHW plate heat exchanger

in a heated condition. This only occurs if the “PREHEAT”

button is pressed and the display reads “PREHEAT ON or

PREHEAT TIMED”.

When there is a demand for CH, the heating system is

supplied at the selected temperature of between 30oC and

80oC, until DHW is drawn o󰀨. The full output from the boiler is

then directed via the diverter valve to the plate heat exchanger

to supply a nominal DHW draw-o󰀨 of

24 9.9 l/min at 35ºC temperature rise.

30 12.4 l/min at 35ºC temperature rise.

35 14.5 l/min at 35ºC temperature rise.

The DHW draw o󰀨 rate specied above is the nominal that

the boiler ow regulator will give. Due to system variations

and seasonal temperature uctuations DHW ow rates/

temperature rise will vary, requiring adjustment at the draw o󰀨

tap.

At low DHW draw-o󰀨 rates the maximum temperature may

exceed 65ºC.

The boiler features a comprehensive diagnostic system which

gives detailed information on the boiler status when operating,

and performance of key components to aid commissioning

and fault nding.

1.3 SAFE HANDLING

This boiler may require 2 or more operatives to move it to its

installation site, remove it from its packaging base and during

movement into its installation location. Manoeuvring the boiler

may include the use of a sack truck and involve lifting, pushing

and pulling.

Caution should be exercised during these operations.

Operatives should be knowledgeable in handling techniques

when performing these tasks and the following precautions

should be considered:

• Grip the boiler at the base.

• Be physically capable.

• Use personal protective equipment as appropriate, e.g.

gloves, safety footwear.

During all manoeuvres and handling actions, every attempt

should be made to ensure the following unless unavoidable

and/or the weight is light.

• Keep back straight.

• Avoid twisting at the waist.

• Avoid upper body/top heavy bending.

• Always grip with the palm of the hand.

• Use designated hand holds.

• Keep load as close to the body as possible.

• Always use assistance if required.

Installation and Servicing

Section 1 - General

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.

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,

BS EN 12828:2012+A1:2014.

Water treatment is covered later in these instructions.

Refer to Section

1.18

1.11 BOILER CONTROLS

Install CH controls to ensure the boiler has no demand when

there is no requirement from the system.

Heating systems with TRVs in individual rooms must include a

thermostat to control the temperature in rooms without TRVs.

At least 10% of the minimum boiler heat output should be

achieved using a room thermostat. A bypass circuit with an

automatic bypass valve must be tted to systems with TRVs or

two-port valves on all the radiators to ensure water ow.

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

Compartment Installations

A boiler installed in a compartment does not require ventilation.

However, A boiler installed in a compartment must provide

adequate clearances for servicing. The compartment should

also be tted with a suitable label in accordance with current

standards.

Refer to Section

1.14

1.8 AIR SUPPLY

t 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.
