1.1 INTRODUCTION

These instructions should be read in conjunction with the Installation and Servicing 
Instructions issued by the manufacturers of the heat source e.g. the boiler used.

Any water distribution and central heating installation must comply with the relevant 
recommendations of the current version of the Regulations and British Standards 
listed below:-

Gas Safety Regulations
Building Regulations
I.E.E. Requirements for Electrical Installations
Water Regulations

British Standards
BS6798, BS5449, BS5546, BS5440:1, BS5440:2, CP331:3, BS6700, BS5258, BS7593 and 
BS7671.

A suitably competent person as stated in the Gas Safety Regulations must install the 
BoilerMate and carry out any subsequent maintenance/repairs. In fact, the front panel 
is secured by 2 screws and should only be removed by a competent trades person.  
The manufacturer’s notes must not be taken as overriding statutory obligations.

The BoilerMate A-Class SP is only suitable for use with a sealed primary central heating 
system. 

The BoilerMate A-Class is not covered by section G3 of the current Building Regulations 
and is therefore not notifi able to Building Control.

The BoilerMate A-Class SP is not intended for use by persons (including children) with 
reduced physical, sensory or mental capabilities, or lack of experience or knowledge, 
unless they have been given supervision or instruction concerning use of the appliance 
by a person responsible for their safety.

Children should be supervised to ensure that they do not play with the appliance.

The information in this manual is provided to assist generally in the selection of 
equipment.  The responsibility for the selection and specifi cation of the equipment 
must however remain that of the customer and any Designers or Consultants 
concerned with the design and installation.

Please Note:  We do not therefore accept any responsibility for matters of design, 
selection or specifi cation or for the effectiveness of an installation containing one of 
our products unless we have been specifi cally requested to do so.

All goods are sold subject to our Conditions of Sale and Warranty Terms, which 
are set out at the rear of this manual.

In the interest of continuously improving the BoilerMate range, Gledhill Water Storage 
Ltd reserve the right to modify the product without notice, and in these circumstances 
this document, which is accurate at the time of printing, should be disregarded.  It will 
however be updated as soon as possible after the change has occurred.  

Description

The BoilerMate A-Class SP shown schematically 
on page 4 is designed to provide sealed system 
space heating and mains pressure hot water at 
high fl ow rates when coupled to any remotely 
sited, condensing or non condensing, boiler 
suitable for sealed heating systems, as long 
as they comply with the recommendations 
contained in the rest of this manual.

The BoilerMate A-Class is an indirectly heated 
hot water only thermal store and is supplied 
with the factory fi tted controls and equipment 
shown in Section 1.2 Technical Data.  The 
indirect heat exchanger is highly effi cient and 
designed to provide extremely quick hot water 
recovery as well as back-up space heating 
when using ‘Switch’.

Because the F & E cistern is only used to fi ll 
the thermal store the standard appliance 
is supplied as a manual fill model, i,e, 
without a ballvalve and overflow, which 
makes it particularly suitable for use in 
fl ats/apartments.  A ballvalve and overfl ow 
fi tting can be supplied as an optional extra if 
required to provide an automatic fi ll model.

Because this product does not require a safety 
discharge from a temperature and pressure 
relief valve, any installations will be easy to 
incorporate into the building and will not suffer 
from the problems associated with using PVCu 
soil stacks to take the discharge from unvented 
cylinders.

An important feature of this concept is that 
hot water can be supplied directly from the 
mains at conventional fl ow rates without the 
need for temperature and pressure relief safety 
valves or expansion vessels.  This is achieved 
by passing the mains water through a plate 
heat exchanger.  The outlet temperature of the 
domestic hot water is maintained by a printed 
circuit board (A.C.B.), which controls the speed 
of the pump circulating the primary water from 
the store through the plate heat exchanger.
