1.1 Important technical warnings and guidelines
For FAULT CODES see Ch. 16 on page 82
T
he EHS Domestic Hot Water systems will, for a long period, com fortably m eet your requir ement of hot water of
the right temperature at th e right hour, prov ided that a few impor tant condit ions have b een fulf illed regardi ng the
installation.
Please follow all instr uctions and recomm endations presente d in this manual b y EHS, especia lly the ones concerning the next important topics:
- Water quality (also see § 8.1 on page 32)
A first necessar y condition is the qual ity of the water t o be heated in the D HW water heater. Thr ee values
matter: hardness, total amount of dissolved solids and acidity. If water quality does NOT meet the requirements
the system may be seriously damaged in time!
♦ Hardness should not exceed 205 PPM CaCO
3
(11,5°dH)
♦ TDS (Total Dissolved Solids) should not exceed 450 PPM
♦ Hardness and TDS together may not exceed 450 PPM
♦ pH value should be between 6,5 and 7,5, measured cold
The actual values can be retrieved at your local water supplier.
I
f water quality doesn’t meet the abovem entioned requir ements, a water tr eatment installat ion should be in-
stalled to improve water quality to the required levels, if possible.
- Water flow velocity and pump
Always use the suppl ied pump f or this heater, th e software a nd param eters are specially set f or this t ype of
pump. All specifications and settings in this manual also refer to this specific pump.
The maximum water flow velocity must be lower as 1 m/sec when using copper pipes.
- Cascading.
We advise NOT to casc ade heaters and/or tanks because d ifferent pum ps and pipe diam eters are needed,
please use the CD heater instead.
Should for any reason cascading still be needed, please contact your supplier. Connect all water heaters and
tanks according to the scheme below (Tichelmann system).
Following the instructions and recommendations given in the referred paragraphs will highly improve the functioning and considerably lengthen the life time of your DHW system.
The applied pump must be controlled b y t he Consul+ water he ater c ontrol o nl y. If, for any reason, an
external pump control is applied with out written appr oval of EHS, t hen the com plete warrant y on the
Consul+ water heater and all delivered parts will become invalid.
E93.0901EN.A Manual Consul+

Warnings and guidelines (continuation)
Furthermore, for all EHS appliances the next instructions and recommendations apply:
! Never use aluminum or aluminum containing flue gas outlet
! Always fill the siphon before commissioning the water heater
! Always set the gas valves during commissioning the water heater, for the first time and after maintenance
and/or installation changes
! Never change the parameters P4AD, P4AA and P5BI
! Never place a valve between the safety valve and the water heater
! In a log, keep track of all situations regarding the appliance:
what, when, by whom, what actions and/or changes, what communication has been performed
EHS is not liable for any damage caused by inaccurately following these mounting instructions.
Only EHS parts may be used when carrying out any repair or service works.
D
o not use chlorine based products for brazing.
W
hen commissioning the water heater, the running of the water heater pump must be checked before leaving the installation.
By pressing the service button during a couple of seconds the water heater can be fired independently from
the thermostat circ uit. Firing the wat er heater without water flow (but f illed with water) will cause a bo iling
noise.
T
he flow and return temperature are checked continuously. The temperature difference may not exceed the
programmed value belonging to the actual power mode. If it does, the water heater will go in a lock-out.
The applied DHW pump must be contro lled only by t he CONSUL+ water heater control. If , for
any reason, an externa l pump control is app lied without written a pproval of EHS, the complete
warranty on the CONSUL+ water heater and all supplied parts will become invalid.
Mi
nimum water pressure 1 bar.
F
uel used should have Sulphur rates that comply with the next values: a maximum annual peak over a short
period of 150 mg/m
3
and an annual average of 30 mg/m3 maximum.
C
ombustion air must be free of contents of chlorine, ammonia, alkali agents. The air near a swimming pool,
a washing machine or a laundry is containing these contents.
T
he water heater is us ed i n c ombination with a hot wat er tank without any other h eat ex chang er; the water
heater should be equ ipped with a safety relief va lve. In s om e cases, also the tank should be equ ipp ed wit h
a T&P relief valve. Always apply all applicable installation standards and regulations.
The connection for a remote DHW Stat is based on an OpenTherm bus system or an on/off timer.
For correct connections of the thermostat see page 36.
At first installation, the built-in automatic air vent should be open.
L
EGIONNAIRES’ DISEASE
An anti-Legionella function is present in the software but is default turned OFF.
See § 8.3 on page 32 and for the programming options § 11.2.2 on page 72.
P
ROPANE GAS
If propane gas is to be used for this water heater, fan speed must be reduced by altering parameter P4BD. See § 11.1.3 at page 76.

1.2 Safety valve
B
etween the water heat er and the safety val ve, DO NOT appl y a closing valve or any other form of narrowing,
because this might disturb the correct functioning of the safety valve.
There is no Safety relief valve or other safety relevant component shipped with the heater. It’s up to the judgement
of the installer/system-designer and applicable standard(s) to subscribe and mount a right safety valve
The CONSUL+ water heater and tank should be installed by a skilled installer according to all applicable standards
and regulations for tap water installations . Use the nex t scheme as guideli ne. When multiple water heaters and
tanks are applied, every combination should be equipped with its own safety valve.
A) Service pipe inlet
B) Hot water supply circulation
C) Circulation return
1) Pressure relief valve (m andatory in case ser vice water pressure is too high)
2) Inlet combination with valve
(mandatory)
3)
Apply filter if necessary
(recommended)
4)
A suitable safety valve
must be mounted near the
water heater (mandatory)
This safety valve may
never be isolated f rom the
w
ater heater by means of a
ball valve
5) Remote tank sensor (necessary) → mounting
hereof: see § 9.2.1 on page

INSTALLATION OF THE CONSUL+
5.1 General notes
At every side of the water heat er at least 50 mm of clearance s hould be applied to walls or wall units, 350 mm
above the top side of the water heater and 250 mm from the bottom of the water heater.
The installation area/room must have the following provisions:
• 230 V - 50 Hz power source socket with earth connection.
• Open connection to the sewer system for draining condensing water
• Gas connection.
Note:
The wall used f or mounting the water h eat er must be able to ho ld th e w eig ht of th e water heater. If th is is no t the
case it is recommended to mount the water heater on a (cascade) frame.
Other considerations related to the water heater location:
• The ventilation of the plant room m ust meet all applicable standards and regulat ions, regardless of the
selected supply of fresh air to the water heater location.
• Both the air supply and the flue gas tubes must be connected to the outside wall and/or the outside roof.
• The installation area must be dry and frost-free.
• The water heater has a built-in fan that will generate noise, depending on the total heat demand. The water
heater location shou ld minimize a ny disturbanc e this m ight cause. Pref erabl y it is suggested to m ount the
water heater on a brick wall.
• There must be sufficient lighting available in the plant room to work safely on the water heater.
• Remind the positioning of electrical components in relation to the temperature sensitivity.
• Make sure there is an open connection with the sewer to drain the condensate. This connection should be
lower than the condensate drain level of the water heater.
The water heater must be positioned and instal led by a certified inst aller in accordanc e with all applicable st andards and regulations . Com m issionin g of the water he ater must be done by a skilled serv ice/comm iss ioning engineer, trained for this type of water heater.
Open connection to the sewer.

5.2 Mounting the water heater and tank
5.2.1 WATER HEATER MOUNTING
Before mounting and installing the water hea ter the following connections should be considered:
• Flue gas system and the flue gas pipe connections
• Air supply system and connections
• ‘Cold in’ and ‘hot out’ pipe connection
• Condensate and pressure relief valve drainage
• Power supply (preferably the power connection is positioned above the water heater)
• Gas connection.
All lines/piping m ust be mounted free of te ns io n. T he weight of all the inst a llati on c omponents should be
supported separately from the water heater so there will be no standing force on the connections.
This might influence the mounting position of the water heater.
Determine the position of the flow and return pipes by using the included sus pension bracket or a suspe nsion
frame (when supplied).
While marking the holes, ensure that the sus pension brack et or frame is perpendicular and the water heater
does not lean for ward. If necessary, adjust the pos iti on with the adjus ting bolts at t he lower rear s ide of the back
panel (see drawing). When the adjusting bolts aren’t sufficient, fill the gap behind the bolts to get the water heater
in position. The exact water heater position lies between the water heater hanging level and hanging slightly backwards.
The water heater should not lean forward in the mounted position.
Lock the suspension bracket with the security cover before making any other connections to the water heater. This
security cover will prevent the water heater from falling off the bracket. Don't use excessive force during the mounting of the water heater connections.
Suspension detail
5.2.2
TANK POSITIONING
The tank must be placed* on a stable floor, but not too far from the water heater(s).
* NB! This floor must be able to hold the weight of the water filled tank(s).
3. Lock water heater with locking
plate and two bolts
1. Attach mounting bracket to wall
with inclined side facing upwards
2. Suspend water heater with suspension bracket on mounting
bracket

FLUE GAS AND AIR SUPPLY SYSTEM
6.1 General
The water heater has a pos itive pr ess ur e f lue system. The available c ombined pressure dro p for the air inlet and
flue gas outlet s ystem, for a single water heater type Consul+3 5, is 100 Pa and for a Consul+55 its 120 Pa
maximum.
It’s not allow ed to use an overpressure s ystem f or a mult iple water heater installation, alwa ys contact the m anufacturer for advice.
Notice:
• Install the horizonta l flue components with an angle of 3° downwards in the direction of the water heater
(roughly equal to five centimeters for every linear m eter). When not installed according ly, it may result i n
condensate building-up in the flue gas tube, eventually causing component failure.
• When using a wall terminal , there is th e possibl e risk of ice b uildin g-up on s urroundi ng parts/s tructures , be-
cause the condensate will freeze. This risk should be considered during the design phase of the DHW installation.
Note:
Because the flue gases can have a relatively low temper ature, the water heater needs to hav e a high eff iciency
approved stainless steel or plastic f lue system. These m aterials should be us able f or the applied pressure in the
flue gas system, be condensate proof and have a temperature class of T120.
Before installing, read the installation manual(s) of the supplier of the flue gas and air supply parts
included with the parts. Manuals for parts supplied by ECO can be found at:

6.3 C63 certified
In general, water heater s are certified with their own flue gas material. For t ype B23, C13, C33, C43, C53, C83
systems, only use flue gas and air supply parts approved according §4.2 and §4.3.
If a water heater is C63 certified, no specific type flue gas material has been certified in combination with the water
heater. In this case the flue gas and air suppl y parts should com ply with the appl icable European standards
(EN14989).
So, for type C63 systems flue gas and air supply parts from other suppliers can be used. It must be able to handle
the condensate form ing (W) and transport, o verpressure (P1) and m ust have a minimum temperature class of
T120. Also, it must meet the requirements in the following chapters "air supply" and "flue terminal".

Co nsult the f lue g as sup plier f or detai led information and engine ering. See also the c ascade manual for these multiple water heater installations.
More information about these common flue gas systems can be found at the cascade-installation manual. You can
find the cascade manual at the website: http://www.ecohs.nl/products/ambassador-/documentation/
6.4 Air supply
When an air suppl y duct is connect ed from the ou tside of the bui lding to the water heater, the water heater will
operate as a room-independent water heater (closed water heater). The air supply duct can be made of:
• PVC / PP
• Thin-walled aluminium
• Stainless steel
6.4.1 C
OMBUSTION AIR QUALITY
Combustion air must be f ree of contaminants. For ex ample: chlorine, amm onia and/or alkali a gents, dust, sand
and pollen. Notice that inst alling a water heater near a swimm ing pool, a washing m achine, laundr y or chem ical
plants does expose combustion air to these contaminants.
6.4.2 A
IR SUPPLY THROUGH HUMID AREAS
When the supply duct will be p laced in a water he ater room with moist air ( for exam ple: gree nhouses) , a doubl e
walled supply duct or an ins ulated duct mus t be used to prevent the pos sible condensat ion at the outside of the
duct. It is not possib le to insulate the internal air pipes of the water heater and therefore co ndensation at the
internal air canals must be prevented.
When roof mounted, the air supply duct needs to be protected against rain, so no water will be entering the water
heater.
No water is allowed to enter the water heater through the air inlet canal at any time.
E93.0901EN.A Manual Consul+
26
6.5 Heights abov e the roof.
Height A
This is the height of the air inlet. A rain hood should prevent
rainwater entering the air supply system.
When the inlet and outlet are mounted on a flat roof, the inlet
should be at least 60 cm above the roof surface and at least 30 cm
above the maximum snow level.
Example 1:
When the maximum s now level on the roof surfac e is 45 cm then
the air inlet shoul d be at 45+30=75 cm . 75 cm is more than the
minimum 60 so the height will be 75 cm.
Example 2:
When the maximum s now level on the roof surfac e is 15 cm then
the air inlet should be at 15+30=45 cm. 45 cm is less than the minimum 60 cm so the height will be 60 cm.
Height difference B
This is the height difference between the flue outlet and the
air inlet.
The flue gas outlet should be at l east 70 cm above the air inlet. It
is advised to be equipped with a conical outlet.
A single flue outlet should be situated at least 100 cm above
the roof surface.
Distance C
The horizontal distance between the flue gas pipe and air inlet
pipe at roof level.
This distance should be at least 70 cm.
