CTC EcoFlex is equipped with a large ash bin to make maintenance easier. Sweeping is usually carried out from CTC EcoFlex wood pellet boiler the top. -
Page 6: Safety Regulations
General Information The way CTC EcoFlex is designed makes it very simple to install. The small dimensions mean that it can be installed in boiler rooms, which are often very small. Most pipe fittings are on the top of the boiler. Electrical installation is to a terminal block behind the control panel. -

CTC EcoFlex... - Page 31 Summer basement heating Background heating in basements/recreation room/bathrooms is often required in the summer months, to avoid damp air. Your EcoFlex can provide this by you setting a “minimum permitted primary flow temperature” to a suitable temperature (15–65°C). See the Installer/Settings/Setting heating/ Min Primfl.
- Page 32 End user information Load monitor EcoFlex has a load monitor. If the system is fitted with a current sensor, the house’s main fuses are then continuously monitored to ensure they are not overloaded. If overloading occurs, an electrical step on the electric cartridge heater is disconnected.

Page 42: Connection To Chimney
15 kW is it in exceptional cases possible to use stainless steel chimney of 90 mm diametet. To less cross section area of the chimney results in insufficient draught in the boiler which may lead to operation disturbances. Recommended chimney draught is 0,1 - 2,5 mBar. CTC EcoFlex... - Page 43 The pellet tube outlet can alternatively be moved up into the hood by the connection of a 1.5 metres feed auger. The feeding time for external feed auger is on the CTC EcoFlex factory pre-set to 30 seconds. By the connection of a feed auger from other manufacturers, the feeding time might need some adjustment.
