3.7 Hydraulic specifications
Depending on the flow, the following diagrams represent: :
For example : Gas 110 Eco 65 with UPS 25-70 130 pump:
- the manometric heights of the heating
- loss of load in the boiler.
manometric height available at 2.61 m3/h = 4.6 mCE - 1.6 mCE = 3
mCE (i.e. 3 mbar)
For a fixed flow, the manometric height available at the boiler outlet
is obtained by taking the difference between the manometric height
of the circulator pump and the loss of load in the boiler.
2.61 m3/h corresponds to a load of 61 kW and a ∆t of 20 K

the boiler will burn at maximum power. The letter G will now appear
on the display.
• "l"-key and q-symbol:
- (symbol) not illuminated: DHW under normal control
- red (symbol) on: DHW off (manual override)
By pressing the [+] and [-]-keys simultaneously, the boiler will return
to operating mode. Following a manual override the boiler will return
to normal (auto control) if no keys are used within a 15 minute period
• [+]-key and u-symbol:
- green (symbol) on: continuous pump operation
- (symbol) not illuminated: pump under boiler control
• Forced mode ‘low’ (H>>)
By pressing the "r" and [-]-key simultaneously in operating mode, the
boiler will burn at minimum power. The letter H will now appear on
the display. By pressing the [+] and [-]- keys simultaneously, the boiler
will return to operating mode. Following a manual override the boiler
will return to normal (auto control) if no keys are used within a 15
minute period.
• [-]-key and n-symbol:
- green (symbol) on: HTG on (manual override)
4.1.4
Display of values with more than two digits
The display has only two digits available therefore values over this
are displayed as follows:
- negative values will be indicated by a dot behind the last digit e.g.
= -10
- values from 00 to 99 will be indicated without any punctuation
marks
- values from 100 to 199 will be indicated by a dot between both
digits e.g. = 100, = 110, & = 199.
- values from 200 to 299 will be indicated by a dot behind every digit
e.g. = for 200, = 210, = 299.

5 Installation
5.1 Statutory terms and conditions of installation and maintenance
The complete installation must comply with the current editions of
relevant British Standards and codes of practice, including the latest
local and national regulations for this type of equipment.
All gas appliances must, by law, be installed by a competent qualified
engineer holding the relevant qualifictions and certificates (for
example ACS and IEE regulations.)
IMPORTANT:
The Broag-Remeha 110 is a CE certified appliance and must not
therefore be modified or installed in any way contrary to these
"Installation and Maintenance Instructions". These manufacturer's
instructions must NOT be taken as overriding statutory obligations.
Failure to install this appliance correctly could result in an unsafe
condition which can lead to prosecution. It is your own interest and
that of safety to ensure that the law is complied with.

5.2 Important comments on the treatment of the heating circuit
Water treatment
„
-
Use untreated tap water only to fill the central heating system.
The pH value of the system water must be between 6 and 9.
Chloride content <20 mg/l
Conductivity <500 µS/cm at 25 °C
In case inhibitors are being used, please follow the instructions
given.
If used correctly water treatment can improve the boilers efficiency
and increase the anticipitated life expectancy of the boiler. For further
information a special document "Remeha water quality regulations"
is available from Broag. The regulations mentioned in this document
must be followed.
As most systems contain a variety of metals, it is considered good
practice to provide some form of water treatment in order to prevent
or reduce the following:
-
metallic corrosion
formation of scale and sludge
microbiological contamination
chemical changes in the untreated system water.
All scale deposists, however small, will reduce
efficiency
of the boiler and should be prevented.
the
New systems should be flushed thoroughly to BS 7593 (1992) to
remove all traces of flux, debris, grease and metal swarf generated
during installation. Care to be taken with old systems to ensure any
black metallic iron oxide sludge and other corrosive residues are
removed, again by power flushing, ensuring that the system is
drained completely from all low points.
Please ensure that the new boiler plant is not in circuit when the
flushing takes place, especially if cleansing chemicals are used
to assist the process.
It is important to check the inhibitor concentration after installation,
system modifications, filling the system and every service in
accordance with these instructions.
For the correct dosage and the suitability of inhibitors for use with our
boilers and for further information on water treatment or system
cleaning we advise direct contact with either of the following

Cold feed and expansion tank height for open
vented systems
We recommend the boiler is installed on a closed (pressurised)
system wherever possible with a minimum operating pressure of 0.8
bar. However, open vented systems can be accomodated as follows:
the cold feed and expansion tank heights for all open vented systems
must comply with the requirements laid down in the Health and
Safety Executive publication (latest edition).
The Gas 110 Eco 115 / 65 series boilers require a minimum static
head of:
- 5 m for Gas 110 Eco 115,
- 3 m for Gas 110 Eco 65.
Suitable chemicals and their use should be discussed with a
specialist water treatment company prior to carrying out any work
(environmental aspects, health aspects). The specification of the
system and manufacturers recommendations must be taken into
account, along with the age and condition of the system.
BETZ DEARNORN Ltd
Sentinal
Foundry Lane
Widnes
Cheshire WA8 8UD
Tel.: 0151 424 5351
Fax.: 0151 420 5447
For operation in open vented systems:
- parameter (flow temperature set-point) must be set to 75 ,
- parameter (boiler modulation start point) must be set to 15,
- parameter (high limit temperature set-point) must be set to 95.
„
Safety valve
A safety valve should be fitted in accordance with the relevant British
Standard.
„
System pump
The boiler must be installed on a fully pumped system.
„
Installing the boiler in existing installations
- Remove sludge from the installation,
- Clean the installation with a universal cleaner to eliminate debris
from the appliance,
- Thoroughly rinse the installation until the water runs clear and
shows no impurities,
- Protect the installation against corrosion and frost with an inhibitor
and an anti-freeze.
The boiler must be used only in closed circuit heating installations. If
you have underfloor heating, the installer must install a safety
thermostat with manual reset to prevent overheating. For an
underfloor heating circuit without system insulation, only oxygen tight
heating pipes must be used. If the plastic pipe manufacturer
recommends a chemical additive, it is necessary to be particularly
careful that there are no contraindications on the aluminum or
aluminum alloy content of components. For floor heating systems
with pipes that are not oxygen tight, the system must be insulated
(heat exchanger). In this case, the floor circuit must be protected
separately (Expansion vessel, Safety valve).
A minimum water level safety device is not necessary. Protection is
ensured by the control unit.
Gas 110 Eco 115 / 65
26/01/2009 - 300014883-001-F
„
Minimum water flow
„
The maximum temperature difference between flow and return, and
the maximum rate of rise of the flow temperature and boiler block
temperature are limited by the boiler modulating controls, as a result,
the boiler is virtually unaffected by low water flow, however for a
continuous supply of heat the boiler requires a minimum flow of 30%
of the nominal flow at the relevant design.
Otherwise, the minimum required flow is:
- 240 l/h for Gas 110 Eco 65,
- 350 l/h for Gas 110 Eco 115.
„
In the event of excessive pump noise
Run-off noise may occur on installations with a direct heating circuit,
fitted with thermostatic valves, under certain conditions of use when
the hydraulic systems are not perfectly balanced.
If this is the case, we recommend fitting a preset differential valve
(200-250 mbar) between the out pipe and the return pipe on the
heating installation.
Location of the installation
Gas 110 Eco 115 / 65 boilers must be installed in a frost-free room.
In order to avoid damage to the boiler, it is necessary to
prevent
the contamination of combustion air by chlorine
and/or fluoride compounds, which are particularly
corrosive. These compounds are present, for example, in
aerosol sprays, paints, solvents, cleaning products,
washing products, detergents, glues, snow clearing salts,
etc.
Therefore:
- Do not suck in air evacuated from premises using such
products: hairdressing salons, dry cleaners, industrial
premises (solvents), premises containing refrigeration
systems (risk of refrigerant leakage), etc.
- Do not stock such products close to the boilers.
If the boiler and/or peripheral equipment are corroded by
such chloride or fluoride compounds, the contractual
guarantee cannot be applied.
The warranty does not apply to damage to the boiler caused by these
instances. If the heating device is installed in residential premises
where people are present all the time, it is necessary to use a
concentric ambient air inlet / combustion gas evacuation installation.
When installing the boiler, it is necessary to comply with degree of
protection IP21.
These actions must be carried out by a qualified engineer
holding
the relevant qualifications and certificates (for
example ACS and IEE regulations).
C001243
Installation must be carried out in accordance with the prevailing
regulations, the codes of practice and the recommendations in these
instructions.
Poor adjustment of the differential valve may cause a
continuous
increase in the return of water to the boiler.
If there are particular requirments for silent running, it is a good idea
to fit a differential pressure regulator (setting 100 -150 mbar).
26/01/2009 - 300014883-001-F
The gas shut off valve should be located on the back of the boiler.
Pipe diameters must be defined in accordance with the current
editions of relevant British Standards and codes of practice, including
the latest local and national regulations for this type of equipment.
To prevent damage caused by overpressure on the gas valve, the
gas supply valve must be closed before carrying out the pressure test
on the gas supply pipe. Decompress before reopening the valve.
In old gas networks, we recommend fitting a gas filter with a large
surface area.
Gas 110 Eco 115 / 65
27
5.3 Water discharge connection
Discharge condensation water directly into the main drain. Given the
degree of acidity (pH 2-5), use only plastic materials to make the
connection. Open the gas valve. Make the connection to the main
drain with a visible flow connection.
The discharge duct must have a minimum gradient of 50 mm/m. The
discharge of condensation water via the gutter is not authorised, given
the risk of frost and the damage to the materials usually used for gutters.
5.4 Room sealed installations
It is unnecessary to provide separate combustion air to the room/
compartment as this is supplied direct to the boiler via the concentric
or eccentric system and the room sealed horizontal or vertical
terminal unit.
For installations where supply and discharge points are in two
different pressure zones (eccentric only), please contact Broag
Technical Dept. for further details and advice.
ZSee chapter 6.1.1
Additional ventilation will be required to the room/compartment in
accordance with the British Standards (compartment ventilation).
NOTE: the boilers can be installed on a flue dilution system, but must
have a total flue break to avoid boiler controls being affected by the
dilution fan pressures. For full details, please contact Broag.
For maximum flue/air inlet length
Comply with British standards BS6644/2005 and BS5440 part 2.
ZSee chapter 6.1.2
5.5 Checking the gas inlet
These actions must be carried out by a qualified engineer.
`
Check the leak tightness of the gas inlet, including the gas
valves.
`
Open all the stop valves on the gas inlet.
`
Empty the gas inlet.
Maximum authorised pressure on the gas valve: 60 mbar. In the
event of higher control pressures, disconnect the boiler from the
gas inlet at the threaded connection to the gas stop valve.
Closing the gas stop valve is not sufficient.

- Type C appliances can only be installed with the systems
mentioned in these technical instructions (particularly concentric
pipes, terminal connection parts).
- As connections of type B23 chimney conduits and type C53
conduits are pressurised, they must be either installed outside or
in a ventilated brick sheath.
Comply with the installation instructions and the information on the
authorised lengths of the flue gas pipes.
ZSee chapter 6.1.2
`
Remove the anti-dust cap.
`
Mount the flue gas pipe or the fresh air/flue gas evacuation
system in compliance with the assembly instructions.
`
Check the seal.
- Static test overpressure: 1000 Pa
- Maximum leak rate: 50 l/hm2 depending on the internal surface of
the flue gas pipe

10 Maintenance
10.1 General
The boiler requires little maintenance if it is correctly set. The boiler
only requires an annual check and cleaning if necessary.
10.2 Inspection
The annual inspection of the boiler can be restricted to the following
operations:
- Measure the combustion and check the operation
- Clean the siphon
- Checking condensates discharge
- Checking the ignition electrode and the ionization sensor
- Set the gap between the ignition electrodes : 3 to 4 mm
- Check the general condition of the flue
- Checking the hydraulic pressure
(minimum 0.3 bar for Gas 110 Eco 65,
minimum 0.5 bar for Gas 110 Eco 115).
Add water to the installation if necessary (Recommended pressure :
1.5 mbar)
- Check the ionization current : 4 to 9 µA.
10.2.1 Checking the combustion in the boiler
This check can be carried out by measuring the CO2/O2 content of
the combusted gas at the measurement point.
Bring the boiler to maximum output up to a water temperature of
around 70°C.

10.4 Maintenance of the air/flue gas drain connection flues
The connection pipes must be checked at least once a year.
- Check the seals.
- Check the condensates evacuation pump in the boiler and on the
pipe if used.
- Replace the leakproof seals and sections of pipe if these no longer
offer a perfect guarantee of leak tightness after being dismantled
during a maintenance operation (only for the visible part of the
flue).
10.5 Temperature sensor
The resistance values at the various temperatures are indicated in
the tables on the next page.
If a faulty sensor is detected, it is possible to check the resistance at
the various temperatures using a meauring device with a
corresponing measurement range (e.g. a multimeter). In order to
obviate incorrect measurements, the sensor must be disconnected
from the connector bar in the boiler distribution panel.
