2.1 General

The Intergas Kombi Kompakt HRE wall mounted, gas fired boiler is a closed appliance. The appliance is intended to deliver heat to the water in a CH system and the DHW installation.

The air supply and combustion gas flue can be connected to the appliance by means of two separate pipes. A concentric connection can be supplied if requested. The appliance has been inspected in combination with the Intergas combi duct, but it can also be connected to combi ducts that comply with the universal requirements for combi ducts and which carry a Gaskeur(Dutch gas certification).

Depending on preference, the appliance may be connected to a mounting bracket, a frame with top connection and various connection sets. These are supplied separately.

The Intergas Kombi Kompakt HRE 24/18 wall mounted gas fired boiler carries the CE EP 20 rating and the Gaskeur (Dutch gas certification) labels HR, SV, NZ and CW Class 3.

This means that the appliance is suitable for supplying at least 6 litres of water per minute at 60C (this corresponds with 10 litres per minute at 40C) or filling a bath with 100 litres of water of average 40C within 12 minutes.

At the on and eco settings the appliance complies with the Gaskeur (Dutch gas certification) CW requirements.

It is possible to use the appliance solely for hot water or solely for heating. The unused system does not have to be connected. (See section 6.3)

The appliance is supplied as standard for natural gas (G25). On request an appliance can be supplied for propane (G31).

2.2 Operation

The Intergas Kombi Kompakt HRE wall mounted, gas fired boiler is a modulating high efficiency boiler. This means that the power is adjusted in line with the desired heat requirement.

The aluminium heat exchanger comprises two separate copper circuits.

As a result of the separately constructed circuits for CH and DHW the heating and hot water supply can operate independently of each other. The hot water supply takes priority over the heating. The two systems cannot operate simultaneously.

The appliance is equipped with an electronic burner manager which, each time heat is requested from the heating or the hot water supply, start the fan, opens the gas valve, ignites the burner and continuously monitors and controls the flame, depending on the requested output.

2.3 Operating modes

A code on the service display of the operating panel indicates the appliances 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 exchanger).

In this operating mode the pressure in the CH installation (in Bar) can also be read on the temperature display.

Waiting modeThe 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 Running on of CH

After the end of CH operation the pump continues to run. The running on time is factory set at he value in accordance with section 6.3 , page:36. 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 het time of the last call for heat. To change the time, the room thermostat setting should be increased briefly at the desired time.

1 Desired temperature reachedThe burner manager can temporarily block the request for heat. The burner is then stopped. Blocking occurs because the requested temperature has been reached. When the temperature has fallen sufficiently the blocking is cancelled.

2 Self-test

The connected sensors are checked regularly by the burner manager. During the check the manager does not perform any other tasks.

3 VentilationWhen 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 burner manager goes into fault mode. (See section 7.2.1).

5 CH operationAn of/off thermostat, an OpenTherm thermostat, an external sensor or a combination of the latter can be connected to the burner manager. (See section 9.1)

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 burner manager 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 burner manager. For the latter two, however, the maximum is the temperature set on the display.

The CH operation the requested CH supply temperature is indicated on the operating panel.

The CH supply temperature can be set between 30C and 90C. (See section 6.1).

The actual CH supply temperature can be read by pressing the service button during CH operation.

When the DHW comfort function is switched on (See code 7 ) any OpenTherm request for heat of less than 40C is ingored.

The resistance R may be removed if the room thermostat does not need anticipation current. (See section 9.1)

6 DHW operation

The hot water supply takes priority over the heating. If the flow switch detects a need for more than 2 l/min of DHW, any demand for CH will be interrupted. After the fan has reached speed (code 3 ) and ignition has taken place (code 4 ) the manager goes to DHW mode (code 6 ).

During DHW operation the fan speed, and hence the power of the appliance, are controlled by the burner manager so that the DHW water temperature reaches the DHW temperature setting.

The water temperature can be set between 40C and 65C (See section 6.1) and is displayed on the operating panel during DHW operation.

The actual DHW temperature can be read by pressing the service button during DHW operation.

7 Pre heating exchanger

To enable fast delivery of domestic hot water the burner manager is equipped with a so-callde DHW comfort function. This function maintains the temperature of the heat exchanger to an adjustable temperature (See section 6.1.). The DHW comfort function has the following settings:

On: ( LED on) The appliances DHW comfort function is switched on continuously. The appliance always delivers hot water immediately.

Eco: ( LED on) The appliances DHW comfort function is self learning. The appliance will adapt to the patttern of use of the hot water tap. As a result, the temperature of the heat exchanger will not be maintained during the night or in the case of lengthy absence.

Off: (Both LEDs off) The temperature of the heat exchanger is not maintained, as a result of which the delivery of hot tapwater takes a little time. If there is no need for fast delivery of hot tapwater, the DHW comfort function can be switched off.

In the case of the on an eco settings the apppliance meets the Gaskeur(Dutch gas certification) central heating requirements.

2.4 PC Interface

The burner manager is equipped with an interface for a PC, which can be connected by means of a special cable and associated software. This facility allows the behaviour of the burner manager , the appliance and the heating installation to be monitored over a longer period.

2.5 Test programs

The burner manager 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.

2.5.1 Frost protection

To prevent freezing of the appliance it is equipped with appliance frost protection. If the heat exchanger temperature falls to low, the burner swiches on and the pump runs until the heat exchanger temperature is sufficient. When the appliance frost protection is actuated code 7 is displayed (pre heating exchanger).

If the installation (or a part of it) can freeze, 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 section 9.1.)

NoteIf the appliance is out of operation ( - on the service display) the appliance frost protection is active. However, a request for heat from an (external) frost thermostat will not be responded to.

10 Warranty provisions

With due regard for the conditions indicated below Intergas Heating BV guarantees to the registered installer the soundness of the materials used, as well as the effective operation of its Central Heating products, when used for the purpose for which they are supplied. As the case arises we should be given the opportunity where necessary to ascertain in situ the soundness of the warranty claim.

The warranty comprises:

The warranty is limited to re-supplying free of charge the parts that entirely in our judgement display material or manufacturing faults during the warranty period, which are not the result of normal wear etc. Such parts should be sent to us carriage paid with an indication of the defect and after replacement will become our property.

190. The warranty period on parts is 2 years, calculated from the date of installation. However, the following parts are excluded from warranty: ignition and ionisation pin, glass fuse, thermocouple and air bleed

191. The warranty period on the sealing of the appliance heat exchanger is 15 years provided, however, that, if in our view locally unavoidable leakages occur as a result of corrosion, we supply solely this boiler component on the basis of reimbursement of old for new calculated from the date of installation at the time of replacement: the first 5 years free, the 6th year 10%, the 7th year 20%, and so on up to the 14th year 90% of the current price of the boiler part to be replaced.

192. The warranty ceases to apply if it is determined that the defects, damage or excessive wear are attributable to improper use or injudicious handling or inexpert repair, adjustment, installation or maintenance, by unauthorised installers or to exposure to substances containing aggressive chemicals (including hair lacquer) and other harmful substances.

193. The warranty also ceases to apply if pipes and couplings have been used in the installation which can cause oxygen diffusion or if the defect is the result of boiler scale deposits (harmful to the appliance and the installation).Surface damage and transport damage are not covered by the warranty. The right to warranty lapses if it cannot be demonstrated that, following commissioning, the central heating boiler or central heating stove has been subjected to a service at least once a year by an installer authorised for that purpose by or on behalf of the gas company. The installation and operating instructions that we issue for the appliances and stoves concerned should be fully adhered to.

194. The manufacturers liability under the agreement is expressly limited to fulfilment of the warranty obligations described in this article. Any claim for compensation with the exception of those relating to non-fulfilment of the warranty obligations is excluded. With due regard for the mandatory legal provisions regarding liability and product liability, no rights may ever be derived with regard to any consequential loss, purely final loss or any loss whatsoever arising from defects in materials supplied or work undertaken by the manufacturer. Furthermore all offers of and agreements regarding products to be supplied and/or services to be provided by us are subject to the general conditions of delivery for the metal and electrical engineering industry, filed by the Dutch Vereniging F.M.E.-C.W.M. on 18 October 1998 with the registry of the district court of The Hague (number 119/1998). A copy of these conditions will be sent free of charge on request. Other conditions are expressly rejected.

195. The warranty is applicable solely if the appendix to the warranty certificate has been signed by the purchaser and returned to us within 8 days following installation. By signing the warranty card the purchaser declares that he/she is in agreement with the sound condition of that which has been delivered.

196. If the installers business ceases operations before expiry of the warranty period, the user may have recourse to our warranty obligations to the installer.

Use as intended.

The appliance, as described in this documentation, is intended for heating rooms via a central heating installation and/or for supplying hot water. Any other use lies outside the intended use of the appliance. No liability can be accepted for loss or damage arising from incorrect use.
