Chemical additions are to be avoided and should only be used after ATAG Heating Technology Ltd has approved their corresponding use. Should you wish to achieve the required water quality by using chemical additives, then this is your own responsibility. The warranty on the product delivered by ATAG Heating Technology Ltd expires, if the water quality does not meet ATAG Heating Technology's specifications or the chemical additives have not been approved by ATAG Heating Technology Ltd.
An existing service pipe must NOT be used without prior consultation with the local gas supplier. ATAG supplies boilers suitable for natural gas only. Verify the identification plate on the boiler if the boiler is suitable for the gas kind on site.
If fitting the regulator outside the regulator should be protected against influences of the weather. The (de-) aeration must be positioned downwards (see figure 9.5.3.a). ATAG advices to install measure points on all gas line parts to have the possibility to check for pressure loss. example propane installation figure 9.5.3.a...
Regulations and Scottish Water Byelaws. The ATAG iC boiler is fitted with a stainless steel plate heat exchanger for producing domestic hot water. The boiler does not have a hot water store and in case of a demand for hot water the boiler will heat the domestic water flowing through the plate heat exchanger up to 60°C (adjustable) instantaneous.
