1.1
HI-SPEC J50 is an open-flued, fan assisted downflow, ducted warm air heater, which may be supplied with MODAIRFLOW
control and in combination with an ELJAN 6 water circulator. A non-MODAIRFLOW version is available as an option.
A Spillage Monitoring Device (TTB) is fitted which senses the temperature in the draught diverter, and shuts down the
appliance when this temperature rises due to the presence of flue gases.

“Summer air circulation” of unheated air is available by manual selection (see User’s Instructions). ELJAN 6 output is 3.32kW
