Drains within the appliance shall have an internal diameter of at least 13 mm.
The main drain for connection to the external drain shall have an internal diameter of at least 18 mm. Condensate drains shall be so designed and arranged that combustion products do not escape via the drains. If the appliance is equipped with a sealed combustion chamber, the condensate formed both in the appliance and in the flue system shall be discharged through one or more condensate drains.
The drains for the flue system may be the same as the drains for the appliance. Condensate formed in the flue system shall drain to a purposely-designed drain. Drains for removal of condensate shall be provided with a means, e.g. a water trap or siphon, to prevent leakage of combustion products or combustion air. If the air heater's condensate outlet is blocked or if a pump for the discharge of condensate fails to operate, the construction shall be such that no hazardous situation can arise when the appliance is operating. 4.5 Condensate neutralization system If the air heater is fitted with a condensate neutralization system, this system shall be designed in such a way that the reagents can be exchanged without dismantling any part of the appliance. SIST EN 1196:2012

5.6.2 Behaviour in the event of blockage or pump failure Blockage of the condensate drain(s) or switching off the pump for the discharge of the condensate shall not lead to concentrations of CO in the combustion products higher than 0,1 %, and spillage of condensate shall not occur before safety shut-down or lock-out occurs. SIST EN 1196:2012

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

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. It is checked that the requirement of 5.6.3 is met. 6.7 Limitation of combustion products temperature The appliance is installed as given in 6.1 and according to the manufacturer's instructions and operated at nominal heat input. 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

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
