Special set up conditions required for condensing air heaters are specified below. The reference conditions for the combustion air apply, with a relative humidity of 50 %. Unless otherwise stated, the appliance is fitted with the minimum flue length as stated by the manufacturer. The temperature of both the air to be heated and the combustion air at the inlet of the appliance shall be maintained at (20 ± 5) °C. 6.2 Draining of condensate The appliance is operated continuously for 4 h in a condensing mode at nominal heat input. During and after this running condition, it is checked if the requirements of 4.4 and 5.2 are fulfilled. 6.3 Soundness of the condensate-carrying parts After the test according to 6.2 it is checked whether the requirement of 5.3 is met. 6.4 Composition of the condensate If required according to 5.4, during the last period of the test according to 6.2, a sufficient quantity of condensate is collected in a suitable (e.g. glass) vessel from the outlet of the appliance, whether or not it is fitted with a neutralization system.

The collected condensate is analyzed for the concentrations of the constituents specified by the manufacturer. It is checked whether the requirement of 5.4 is met. SIST EN 1196:2012

EN 1196:2011 (E) 8 6.5 Condensate neutralization system If the air heater is fitted with a condensate neutralization system, during the last period of the test according to 6.2, a sufficient quantity of condensate is collected in a suitable (e.g. glass) vessel from the outlet of the appliance.

This may be the condensate collected according to 6.4. The pH value of this condensate is measured and it is checked that the requirement of 5.5 is met. 6.6 Condensate discharge system 6.6.1 Capacity The sizing of the condensate draining system or the capacity of a pump is checked by the introduction of the following equivalent rates of water into the draining system:  for natural gas: 2 l/h water per m3/h of natural gas;  for propane: 3 l/h water per m3/h of propane;  for butane: 4 l/h water per m3/h of butane. The minimum volume of water used for this test is 2 l.

If the condensate drain is a combined drain for the combustion circuit and the flue, then the volumes stated above are increased by a factor of 2. NOTE The volumes above take into account the possibility of the penetration of rain or snow into the flue system as designed by some manufacturers. It is checked if the requirement of 5.6.1 is met. 6.6.2 Behaviour in the event of blockage or pump failure The appliance is operated continuously in a condensing mode at nominal heat input. With the condensate drain blocked or with a pump for the discharge of condensate put out of operation, it is checked if the requirement of 5.6.2 is met. In order to accelerate the test, water may be added to the condensation circuit. 6.6.3 Soundness of the combustion circuit The appliance is installed with the maximum flue length specified by the manufacturer, and operated with the maximum pressure in the combustion chamber.

The appliance is supplied with one of the corresponding reference gases for the appliance category. After reaching thermal equilibrium, the appliance overheat cut-off device or air temperature limiter is rendered inoperative and the air delivery fan is put out of action.

The temperature of the combustion products is measured until the appliance is switched off by the device for limiting the combustion products temperature. It is checked that the requirement of 5.7 is met. SIST EN 1196:2012

EN 1196:2011 (E) 9 6.8 Efficiency 6.8.1 General The appliance is installed according to the manufacturer's instructions.

The air heater is supplied with one of the corresponding reference gases for the appliance category. The efficiency (on net calorific value), i, expressed as a percentage, of the appliance is determined at each heat input specified by the manufacturer, using the indirect method based on the following equation: 100)(21−++−=iiiHSqqHη

(1) where Hi

is the net calorific value in megajoules per cubic metre (MJ/m3) at 15 °C, 1 013,25 mbar, dry; S is the condensing correction (MJ/m3 gas); this factor S is determined according to the procedure given in Annex A; q1 is the heat of the dry products of combustion divided by the heat input based on the net calorific value in per cent (%); q2 is the heat of the water vapour contained in the products of combustion divided by the heat input based on the net calorific value in per cent (%). 6.8.2 Efficiency at nominal heat input The appliance is operated at nominal heat input. The flow rate of the air to be heated is controlled so as to be equal to the minimum stated by the manufacturer. Under these conditions it is checked if the requirement of 5.7 is met. 6.8.3 Efficiency at minimum heat input The appliance is operated at minimum heat input.

The flow rate of the air to be heated is controlled so as to be equal to the minimum stated by the manufacturer. Under these conditions it is checked if the requirement of 5.7 is met. 7 Marking and instructions 7.1 Marking In addition to the marking as required in the associated appliance standard, i.e. EN 778, EN 1020 or EN 1319, the following applies:  on the appliance and also the packaging it shall be clearly stated that it is a condensing appliance and that local regulations may apply with respect to the discharge of condensate as effluent;  type C6 appliances shall carry a firmly attached label indicating limitations of materials suitable for use with the appliance including the maximum operating temperature that the flue shall be capable of withstanding during use. The label shall draw the attention to the installation instructions on this subject, and shall be located near the flue gas outlet. SIST EN 1196:2012

EN 1196:2011 (E) 10 7.2 Installation instructions 7.2.1 General In addition to the instructions as required in the associated appliance standard, i.e. EN 778, EN 1020 or EN 1319, the installation instructions shall contain the following information: a) precise specifications for the flue, combustion air ducts and condensate discharge systems, including the amounts of condensate produced by the appliance and/or its flue system; in particular, attention shall be drawn to the necessity of avoiding horizontal runs in flues and drains; b) a list of appropriate materials suitable for use on flue systems and any temperature limits that apply; c) if appropriate, instructions for dismantling of the heat exchanger in which condensate is formed; d) instructions for the installation of the appliance in situations where a condensate neutralization system is to be installed;

e) reference to the national and/or local regulations that may apply for the discharge of condensate; f) drawing the installer's attention to the possibility of condensate freezing in the condensate drain system and external flue components; g) any special instructions for commissioning and servicing. 7.2.2 User's instructions In addition to the instructions as required in the associated appliance standard, i.e. EN 778, EN 1020 or EN 1319, the user's instructions shall contain a brief description of the operation of the air heater.

SIST EN 1196:2012

EN 1196:2011 (E) 11 Annex A (normative)

Determination of the condensing correction factor (S in the efficiency equation) The correction is based on the condensate collected in kg of condensate per m3 gas used. For dry appliances, S = 0. For condensing appliances, S is calculated with the following equation: S - S + S = SCBA

(A1) where SA

is the heat of condensation recovered by the condensate collected (in MJ/m3 gas) at the reference temperature (15 °C);

= condensate collected (kg/m3 gas) × heat of condensation at 15 °C (2,466 MJ/kg); SB

is the sensible heat in (MJ/m3 gas) between the reference temperature (15 °C) and the flue gas temperature of that water vapour which has been condensed.

NOTE 1 This amount of sensible heat has, therefore, not been lost to the flue and so the sensible heat loss is reduced by the amount, therefore:

SB = condensate collected (kg/m3 gas) × 1,294 × enthalpy (water vapour) × ûT1.

NOTE 2 The figure 1,294 is the ratio of water vapour in m3 per kg of condensate at 15 °C.

This figure may be rounded to 1,3 to take account of vapour losses in the condensate circuit.

NOTE 3 The enthalpy of water vapour is taken as 0,001 42 MJ/(m3·K) SC

is the sensible heat loss of the condensate liquid above the reference value (15 °C) in MJ/m3 gas;

= condensate collected (kg/m3 gas) × specific heat (0,004 18 MJ/kg⋅K) × ûT2.

NOTE 4 ûT2 is the temperature difference between the reference value (15 °C) and the temperature of the condensate at the appliance drain outlet, as compared with ûT1 which is the temperature rise of the combustion products above the reference value. SIST EN 1196:2012

Special set up conditions required for condensing air heaters are specified below. The reference conditions for the combustion air apply, with a relative humidity of 50 %. Unless otherwise stated, the appliance is fitted with the minimum flue length as stated by the manufacturer. The temperature of both the air to be heated and the combustion air at the inlet of the appliance shall be maintained at (20 ± 5) °C. 6.2 Draining of condensate The appliance is operated continuously for 4 h in a condensing mode at nominal heat input. During and after this running condition, it is checked if the requirements of 4.4 and 5.2 are fulfilled. 6.3 Soundness of the condensate-carrying parts After the test according to 6.2 it is checked whether the requirement of 5.3 is met. 6.4 Composition of the condensate If required according to 5.4, during the last period of the test according to 6.2, a sufficient quantity of condensate is collected in a suitable (e.g. glass) vessel from the outlet of the appliance, whether or not it is fitted with a neutralization system.

The collected condensate is analyzed for the concentrations of the constituents specified by the manufacturer. It is checked whether the requirement of 5.4 is met. kSIST FprEN 1196:2011

FprEN 1196:2011 (E) 8 6.5 Condensate neutralization system If the air heater is fitted with a condensate neutralization system, during the last period of the test according to 6.2, a sufficient quantity of condensate is collected in a suitable (e.g. glass) vessel from the outlet of the appliance.

This may be the condensate collected according to 6.4. The pH value of this condensate is measured and it is checked that the requirement of 5.5 is met. 6.6 Condensate discharge system 6.6.1 Capacity The sizing of the condensate draining system or the capacity of a pump is checked by the introduction of the following equivalent rates of water into the draining system:  for natural gas: 2 l/h water per m3/h of natural gas;  for propane: 3 l/h water per m3/h of propane;  for butane: 4 l/h water per m3/h of butane. The minimum volume of water used for this test is 2 l.

If the condensate drain is a combined drain for the combustion circuit and the flue, then the volumes stated above are increased by a factor of 2. NOTE The volumes above take into account the possibility of the penetration of rain or snow into the flue system as designed by some manufacturers. It is checked if the requirement of 5.6.1 is met. 6.6.2 Behaviour in the event of blockage or pump failure The appliance is operated continuously in a condensing mode at nominal heat input.

With the condensate drain blocked or with a pump for the discharge of condensate put out of operation, it is checked if the requirement of 5.6.2 is met. In order to accelerate the test, water may be added to the condensation circuit. 6.6.3 Soundness of the combustion circuit The appliance is installed with the maximum flue length specified by the manufacturer, and operated with the maximum pressure in the combustion chamber.

The air heater is supplied with one of the corresponding reference gases for the appliance category. The efficiency (on net calorifiv value), i, expressed as a percentage, of the appliance is determined at each heat input specified by the manufacturer, using the indirect method based on the following equation: 100)(21−++−=iiiHSqqHη

11 where Hi

is the net calorific value in megajoules per cubic metre (MJ/m3) at 15 °C, 1 013,25 mbar, dry; S is the condensing correction (MJ/m3 gas); this factor S is determined according to the procedure given in Annex A; q1 is the heat of the dry products of combustion divided by the heat input based on the net calorific value in per cent (%); q2 is the heat of the water vapour contained in the products of combustion divided by the heat input based on the net calorific value in per cent (%). 6.8.2 Efficiency at nominal heat input The appliance is operated at nominal heat input.

The flow rate of the air to be heated is controlled so as to be equal to the minimum stated by the manufacturer. Under these conditions it is checked if the requirement of 5.8 is met. 6.8.3 Efficiency at minimum heat input The appliance is operated at minimum heat input.

The flow rate of the air to be heated is controlled so as to be equal to the minimum stated by the manufacturer. Under these conditions it is checked if the requirement of 5.8 is met. 7 Marking and instructions 7.1 Marking In addition to the marking as required in the associated appliance standard, i.e. EN 778, EN 1020 or EN 1319, the following applies:  on the appliance and also the packaging it shall be clearly stated that it is a condensing appliance and that local regulations may apply with respect to the discharge of condensate as effluent;  type C6 appliances shall carry a firmly attached label indicating limitations of materials suitable for use with the appliance including the maximum operating temperature that the flue shall be capable of withstanding during use. The label shall draw the attention to the installation instructions on this subject, and shall be located near the flue gas outlet. kSIST FprEN 1196:2011

FprEN 1196:2011 (E) 11 Annex A (normative)

Determination of the condensing correction factor (S in the efficiency equation) The correction is based on the condensate collected in kg of condensate per m3 gas used. For dry appliances, S = 0. For condensing appliances, S is calculated with the following equation: S - S + S = SCBA

22 where SA

is the heat of condensation recovered by the condensate collected (in MJ/m3 gas) at the reference temperature (15 °C);

= condensate collected (kg/m3 gas) × heat of condensation at 15 °C (2,466 MJ/kg); SB

is the sensible heat in (MJ/m3 gas) between the reference temperature (15 °C) and the flue gas temperature of that water vapour which has been condensed.

NOTE 1 This amount of sensible heat has, therefore, not been lost to the flue and so the sensible heat loss is reduced by the amount, therefore:

SB = condensate collected (kg/m3 gas) × 1,294 × enthalpy (water vapour) × ûT1.

NOTE 2 The figure 1,294 is the ratio of water vapour in m3 per kg of condensate at 15 °C.

This figure may be rounded to 1,3 to take account of vapour losses in the condensate circuit.

NOTE 3 The enthapy of water vapour is taken as 0,001 42 MJ/(m3·K) SC

is the sensible heat loss of the condensate liquid above the reference value (15 °C) in MJ/m3 gas;

= condensate collected (kg/m3 gas) × specific heat (0,004 18 MJ/kg⋅K) × ûT2.

NOTE 4 ûT2 is the temperature difference between the reference value (15 °C) and the temperature of the condensate at the appliance drain outlet, as compared with ûT1 which is the temperature rise of the combustion products above the reference value. kSIST FprEN 1196:2011
