Instructions for installation and servicing ecoMAX4
1 Introduction
1.1 Introduction
Note:
This boiler must be installed and serviced by a
competent person in accordance with the Gas
Safety (Installation and Use) Regulations 1998.
In the UK ‘CORGI’ registered installers under
take the work to a safe and satisfactory stan-
dard.
ecoMAX 800 range
The ecoMAX 800 range is a fully automatic, wall moun-
ted, room sealed condensing (high efficiency) combinati-
on boiler for central heating and domestic hot water.
Domestic hot water is supplied directly from the boiler,
without requiring a copper cylinder, cold water tank,
feed and expansion tank and associated pipework.
Domestic hot water has priority over central heating.
The ecoMAX 800 range consists of models with outputs
for domestic hot water of 23 kW, 28 kW and 35 kW. All
versions are available in natural gas. The 28 kW version
version is also available in LPG.
ecoMAX combination boilers incorporate a warmstart
facility that keeps the domestic hot water heat exchan-
ger hot, providing an instantaneous delivery of domestic
hot water. The temperature in the domestic hot water
heat exchanger is limited by the boiler control system
and it is not necessary to install a scale reducer on the
cold mains to the boiler. However, in exceptionally hard
water areas to prevent scale formation in the property
hot water system pipework, a scale reducer may be fit-
ted. The heating system can be filled using the built–in
filling loop contained within the boiler.
ecoMAX 600 range
The ecoMAX 600 range is a fully automatic, wall moun-
ted, room sealed condensing (high efficiency) system
boiler for central heating and domestic hot water (where
a separate indirect hot water storage cylinder is also
incorporated in the system). The ecoMAX 600 range
consists of models with outputs of 13, 18, 22 and 35 kW.
All ecoMAX 600 range boilers are available in Natural
Gas. The 22 kW version is also available in LPG.
1.2 General Notes
The boilers have been designed for use with a sealed
central heating system, and come fully tested and
assembled with a built in circulating pump, expansion
vessel and diverter valve (ecoMAX 800). The boilers are
easily sited on any internal wall and can be installed with
either a horizontal or vertical RSF (room sealed fan assi-
sted) flue.
The boilers use a standard flue system (100 mm outside
diameter) which allows flue lengths up to 8m (ecoMAX
828/2, 613/2, 618/2 and 622/2) 7m (ecoMAX 824/2) and
4 m (ecoMAX 635, 835). Flue extensions and additional
bends and elbows are available for the flue system to
increase the siting flexibility. If desired, an inhibitor may
be used in the system. Guidance on the use of inhibitors
is contained in these instructions.
All boilers have a built in diagnostic system which indica-
tes the operational status of the boiler. This feature pro-
vides key information to aid commissioning and fault fin-
ding. The data badge is fitted to the underside of the
boiler. See text of General Requirements for installation
requirements or notes.
1.3 EC designation
ecoMAX boilers carry the ‘CE’ Mark. This demonstrates
that the boilers fulfil the essential requirements of the
Gas Appliance Directive (90/396/EEC) and the Gas
Appliance (Safety) Regulations 1992.
The ‘CE’ Mark also demonstrates that the boilers comply
with the requirements of the Electromagnetic
Compatibility Directive (89/336/EEC), the Low Voltage
Directive (72/23/EEC), the Boiler Efficiency Directive
(92/42/EEC) and the Boiler (Efficiency) Regulations 1993.
Vaillant Ltd. support the Benchmark initiative.
Within the information pack, you will find a
Benchmark Log Book. It is very important that
this is completed correctly at the time of instal-
lation, commissioning and handover to the user.
