4Plate Heat Exchanger Package
Section 1 - Introduction
This manual contains information for dimensioning & assembly
of a Plate Heat Exchanger Package for the Evomax 2 range of
commercial boilers.
1.1 INTRODUCTION
1.2 GENERAL DESCRIPTION
This package provides the means to install an Evomax 2 boiler
complete with a plate heat exchanger and associated ancillary
items to separate the boiler hydraulically (primary) from an
existing heating / hot water system (secondary).
See appliance manuals for the ue congurations for the range
of appliances using this kit.
150 kW boilers must be ued following the Clean Air Act.
All headers and pipework should be insulated following the
Non-Domestic Building Services Compliance Guide.
Insulation thickness must be calculated according to BS EN
ISO 12241 using standardised assumptions.
This package is intended for system separation only and must
not be used for instantaneous domestic hot water generation.

Section 2 - General Description
2.3 OUTPUT CONTROL
The package can be used with an optional accessory boiler
pump, available separately. The package can also be used
with compatible boilers having an internal boiler pump. Pumps
are designed to be wired to and controlled by the appliance to
allow a controlled pump over run.
2.4 GAS SUPPLY
Evomax 2 30, 40, 80, 60, 100, 120 & 150 boilers are
congured for use with natural gas. The 30P, 40P, 60P,
80P, 100P & 120P boilers are congured for use with LPG /
Propane.
The package requires the gas inlet to be made up to the gas
tap provided, connecting it to the appliance's inlet. Assembly
of the gas supply pipework and connection to the gas supply
must follow all the applicable regulations.
A purge valve with a test point is provided before the boiler
gas tap. This test point nearest the appliance gas inlet is
intended to be used as the appliance inlet pressure test point.
2.5 SAFE HANDLING
Take appropriate measures to ensure safe handling of this
appliance, use multiple operatives and or lifting equipment if
necessary.
Operatives should be knowledgeable in handling techniques
when performing these tasks and the following precautions
should be considered:
• Use appropriate handling points
• Be physically capable
• Use personal protective equipment as appropriate, e.g.
gloves, safety footwear
During all manoeuvres and manual 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
2.1 PLATE HEAT EXCHANGER KIT
OPTIONS
This kit is provided with a plate heat exchanger suitable to
cover a single boiler installation from the range of available
Evomax 2 boilers.
The kit is based on a low height frame and allows hydraulic
separation of the boiler from the secondary system in a
compact envelope.
Consider the modulation range of the appliance and total
heat load requirements when sizing the boiler.
The package and the boiler pumps are intended to operate
with a temperature di󰀨erence of 20 °C across the appliance
to provide a 20 °C temperature di󰀨erence on the secondary
side of the plate.
Typical boiler and system side operating parameters are
85/65 °C and 75/55 °C respectively.

2.2 HYDRAULIC SEPARATION: PLATE
HEAT EXCHANGER
A plate heat exchanger supports hydraulic separation within a
hydronic system allowing two ows to operate independently
with their ow and pressure environments.
The brazed plate heat exchanger used within the package
ensures e󰀨ective heat transfer and optimum e󰀩ciency with low
ow resistance and a compact footprint.
The heat exchanger allows hydraulic separation between the
boiler and a heating circuit, covering duties up to 150 kW.
This enables the modern, high e󰀩ciency condensing boilers
to operate under their optimum conditions, while the adjoining
heating circuit operates to its optimum controlled requirements.
The plate's design is based on standard components and a
modular brazed concept. Each unit is manufactured to the
highest standard and part of the AHRI certied program that
ensures thermal performance under the product specications.
Benets:
• Compact design
• No gaskets
• Easy installed within the plate heat exchanger package
• Low maintenance/ self-cleaning
• All plates are pressure tested during manufacture
CAUTION: Caution should be exercised during these
operations.
