3 GENERAL BOILER INFORMATION
3.1 General
The Intergas Compact HRE SB wall mounted, gas fired boiler is a closed appliance.
The appliance is intended to transfer heat to the water circuit in a CH system and when
an indirectly heated domestic hot water (DHW) storage cylinder is installed, apply heat
to the DHW installation.
The air supply and combustion gas flue connection is as standard prepared for a
concentric 60/100 horizontal flue system. The appliance can be connected to a wall
mounting jig and expansion vessel. The appliance can also be connected without the
wall mounting jig using the robo kit.
The Intergas Compact HRE SB wall mounted gas fired boiler carries the CE rating and
IP44 electrical protection.
The appliance is supplied as standard for natural gas (G20). For usage of propane gas
(G31) the boiler can be modifed by changing the gas injector. A gas conversion kit can
be ordered at Intergas Heating Ltd.
NOTE
Modification of the boiler can only be done by a qualified
competent person.
3.2 Boiler controller
An electronic control unit, consisting of a boiler controller and separate ignition module
which is placed on the gas valve, provides direct burner ignition and flame supervision
along with continuous modulation of the burner’s gas supply.
3.3 Parameter list
All boiler adjustments are accessible through the parameter list in the software.
3.4 Heat transfer
Heat transfer to the boiler’s heating circuit is obtained via a primary, gas to water heat
exchanger within a hermetically sealed combustion chamber. A modulated speed fan
blows the gas/air mixture into the combustion chamber and expels the products of
combustion to outside air via an associated flue system.
3.5 Central heating system/automatic by-pass
An integral pump located in the boilers hydraulic circuit circulates water through the
heat exchanger to the central heating circuit. In the event of reduced or interrupted
water circulation in the central heating circuit, an automatic system by-pass should be
fitted as far away from the boiler as possible.
Note
It is no longer permissible to utilize a non-thermostatic controlled radiator as a by-pass.
3.6 Room temperature control
Room temperature can be controlled by the use of an external room thermostat and
thermostatic radiator valves.
Note
Connection of the room thermostat is dependant on the operating voltage of the
thermostat.
3.7 Integrated clock
The boiler incorporates an integrated clock, which allows the setting of central heating
periods (See the User Instructions, ‘Operation and display read-out’ for details) and the
boiler’s control panel incorporates an LED display, which indicates the state of
operation and fault defect codes.
Note
For S and Y plans set integral clock to C-ON and fit an external timer/programmer.
Intergas Heating Ltd 12
4 OPERATION
4.1 General
The Intergas Compact HRE SB wall mounted, gas fired system boiler is a modulating
high efficiency boiler. This means that the power is adjusted in line with the desired heat
requirement.
The appliance is equipped with an electronic boiler controller which, each time heat is
requested from the heating supply, starts the fan, opens the gas valve, ignites the
burner and continuously monitors and controls the flame, depending on the requested
output.
4.2 Central heating mode
When a heating demand is requested (power is on, the timer and thermostat are calling for
heat) the integral pump is energised and the boiler will fire automatically. The hot water is
now circulated around the central heating system. When the end of the central heating
demand is reached (the thermostat reaches temperature or the time clock reaches the end of
its set period) the burner will shut down while the pump remains functioning during a preset
period of time to dissipate any excess heat from within the boiler’s heat-exchanger. After that
the boiler will revert to stand-by, waiting to respond to the next heating demand.
4.3 Operating modes
A code on the service display of the operating panel indicates the appliance’s operating
mode.
-
Off
The appliance is out of operation but is supplied with electrical power. No response
occurs to calls for DHW or CH. The appliance frost protection is active. This means that
the pump operates and the exchanger is heated up if the temperature of the water
present in it falls too far.
If the frost protection is actuated, code
7
is displayed (heating the exchanger).
In this operating mode the pressure in the CH installation (in Bar) can also be read on
the temperature display.
Waiting mode
The LED at the button is lit and possibly one of the LEDs for the DHW comfort
function. The appliance is ready to respond to a request for CH of DHW.
0
Pump overrun of CH
After the end of CH operation the pump continues to run. The running time is factory set at
the value in accordance with § 10.3. This setting can be changed.
In addition, the pump runs automatically for 10 seconds once every 24 hours in order to
prevent seizing. This automatic switching on of the pump occurs at the time of the last call for
heat. To change the time, the room thermostat setting should be increased briefly at the
desired time.
1
Boiler shutdown when required temperature reached
The boiler controller can temporarily shut down the request for heat. The burner is then
stopped. Shutdown occurs because the requested temperature has been reached.
When the temperature has fallen sufficiently and the anti cycle time has passed the
shutdown is cancelled.
2
Self-test
The connected sensors are checked regularly by the boiler controller. During the check
the boiler controller does not perform any other tasks.
3
Ventilation
When the appliance is started the fan is first brought to starting speed. When the
starting speed has been reached the burner is lit. Code 3 is also visible when post-
ventilation is taking place after the burner has stopped.
4
Ignition
When the fan has reached the starting speed, the burner is ignited by means of
electrical sparks. During ignition the code
4
is visible. If the burner does not ignite, a
new ignition attempt occurs after approximately 15 seconds. If after 4 ignition attempts
the burner is not yet burning, the boiler controller goes into fault mode (See § 11.1 ).
Intergas Heating Ltd
13
5
CH operation
An on/off thermostat, an OpenTherm thermostat, an external sensor or a combination of
the latter can be connected to the boiler controller.
When a request for heat is received from a thermostat, the fan is started (code 3 ),
followed by ignition (code
4
) and CH operating mode (code 5 ).
During CH operation the fan speed and hence the appliance power are controlled by
the boiler controller so that the CH water temperature reaches the desired CH supply
temperature.
If an on/off thermostat is connected, this is the CH supply temperature set on the
display. In the case of an OpenTherm thermostat the desired CH supply temperature is
determined by the thermostat. In the case of an external sensor the desired CH suppply
temperature is determined by the heating line programmed in the boiler controller. For
the latter two, however, the maximum is the temperature set on the display.
During CH operation the requested CH supply temperature is indicated on the operating
panel.
The CH supply temperature can be set between 30°C and 90°C.
4.4 Clock function (heat only)
The boiler is equipped with a digital clock and offers the possibility to program 4 points in time
to switch from CH off or CH on.
During the “clock active” periods the boiler will respond on CH demands from the room
thermostat. During the “clock inactive” periods the boiler will not respond on CH demands.
N.B. The clock function is only applicable when using the boilers as “heat only”. When using the
boiler in combination with an external DHW tank, for example in an S or Y plan wired installation
the clock must be set to C-on.
Additionally the following special modes can be chosen:
1. t-on (temporary on).
The boiler will respond to every CH demand from the room thermostat until the next switch
moment.
2. c-on (continuous on).
The boiler will respond to every CH demand from the room thermostat without any time limit.
3. OFF.
The boiler will not respond to any CH demand from the room thermostat.
NOTE
For setting and adjusting the clock see § 9.3 Setting and adjusting the clock
functions.
4.5 PC Interface
The boiler controller is equipped with an interface for a PC, which can be connected by
means of a special cable and associated Intergas Diagnostic Software (IDS). This
facility allows the behaviour of the boiler controller, the appliance and the heating
installation to be monitored over a longer period.
Intergas Heating Ltd 14
4.6 Test programs
The boiler controller has a facility for placing the appliance in test mode. Activation of a
test program will result in the appliance starting operation at a fixed fan speed, without
the control functions being actuated. The safety functions do remain active. The test
program is ended by pressing the and simultaneously or will end automaticaly
after 10 minutes.

4.7 Frost protection
FROST PROTECTION
To prevent freezing the appliance is equipped with an internal frost
protection. If the heat exchanger temperature falls too low, the burner
switches on and the pump runs until the heat exchanger temperature
is sufficient. When the appliance frost protection is activated the
symbol code
7777
is displayed (pre heating the heat exchanger).
If the installation (or a part of it) is in danger of freezing, an (external)
frost thermostat must be fitted to the return line at the coldest location.
This must be connected in accordance with the wiring diagram
(See § 8.3).
NOTE
If the appliance is out of operation (
-
on the service display) the appliance’s
internal frost protection is still active. However, there will be no response to a
heating demand from an (external) frost thermostat.

Before fitting the boiler ensure that the pipe work that you are installing is connected to
the appropriate connections on the boiler.
It is important to thoroughly flush the water circuits, after isolating the boiler, in order to
remove any fluxes and debris from them. This should be done particularly where boilers
are being fitted to existing radiator circuits (please refer to current Standard Codes of
Practice).
•
BS 7593:2006 for the details to clean DHW and Central heating system.
•
This boiler has been factory set but adjustment may be required to the heating input in
order to match the individual heating demand. This can be done by changing parameter
3 (= max. power CH) or parameter 4 (= max. power domestic water).
•
Please do not use the pressure relief valve as a means of flushing the system.
•
Remember that after hot water draw of a possible delay may occur before the heating
system will fire up.
•
All fluxes, residues and cleaner must be flushed from pipe-work and radiators prior to
commissioning.
•
External expansion vessels are best connected water side downwards to allow correct
draining/cleaning of system and to prolong the life of the vessel diaphragm.
•
Note: an anti-cycle delay time can be set up to a maximum of 15 minutes by adjusting
parameter P as described in § 10.3.
•
If you experience any problems please refer to the installation and commissioning
guidelines within the boiler instruction manual. If necessary, please contact Intergas
Heating Ltd (See § 1.8).
Remember it is a requirement to complete the Benchmark code of practice logbook before
leaving the installation. You are also required to register the boiler through the Gas Safe
registration scheme.
