Page 6: Unit Description
The modulating, gas wall-mounted automatic heaters The burner can be operated with gases of the second of the GPC series has been developed for the heating family (natural gas - group H and L) and with gases of industrial and commercial spaces. - Page 7 Fans Air/gas premix The switching on of the fans is time-controlled The units are equipped with a burner with complete by the control board, whereby the timing begins air/gas premix. with the switching-on of the main burner. This mixing process takes place in the fan of the burner motor.
- Page 8 REMKO GPC series Cycle of operation The units from the GPC range are fully-automatic hot If the flame cannot be ignited then 4 further ignition air heaters, which are equipped with an electronic attempts take place. With the fifth ignition attempt, device with self-testing and with a microprocessor the GPC board triggers a fault lock-out.
- Page 9 Intrinsic safety The increase in efficiency with minimum output is achieved through the use of a modern air/gas mixture technology and the simultaneous flow rate regulation of combustion air and gas. This technology increases the safety of the unit, because the gas valve feeds the fuel depending on the amount of air in accordance with its factory settings.
