Installation and Servicing

Section 1 - General

1.1

INTRODUCTION

The

Logic Heat

range of boilers are wall mounted, full

sequence, automatic spark ignition, low water content, fanned

flue, high efficiency, condensing, heating only gas boilers.
Due to the high efficiency of the boiler a plume of water vapour

will form at the terminal during operation.

A variable temperature control is fitted on the user control.
The boiler includes as standard:

Boiler frost protection

Notes

. The appliance must be wired with a permanent live

supply, or the boiler frost protection will not operate.
The boiler warranty will be invalid if these requirements are not

complied with.

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

front panel.
The boiler temperature control is visibly located in the control

panel on the front of the boiler.
The heat exchanger is manufactured from cast aluminium.
Note that these boilers cannot be used on systems which

include gravity circulation.
The boiler is suitable for connection to fully pumped open

vented or sealed water systems. 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 upwards.

A rear flue outlet kit (55/80) is available which provides a

compact installation.

Data Plate

The boiler model and serial number can be located on the

bottom of the boiler casing, shown in Section 1.16 - Water &

Gas Connection Diagram.

1.2

OPERATION

When there is a demand, the heating system is supplied at the

selected temperature of between 30

C and 80

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 finding.

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.

SAFETY

Current Gas Safety (installation and use) regulations or

rules in force:

The appliance is suitable only for installation in GB and should

be installed in accordance with the rules in force.
In GB, the installation must be carried out by a Gas Safe

Registered Engineer. It must be carried out in accordance with

the relevant requirements of the:

• Gas Safety (Installation and Use) Regulations
• Appropriate Building Regulations, either The Building

Regulations, The Building Regulations (Scotland), Building

Regulations (Northern Ireland).

• Water Fittings Regulations or Water byelaws in Scotland.
• Current I.E.E. Wiring Regulations.

Where no specific instructions are given, reference should be

made to the relevant British Standard Code of Practice.

The Boiler has been tested and certified to;

BSEN 15502-1, BSEN 15502-2, BSEN 15502-2-1, BSEN

60335-1, BSEN 60335-2-102, BSEN 55014-1 and BSEN

55014-2 for use with Natural Gas & Propane.
