1. BRIEF DESCRIPTION
1.1 HI-SPEC J25 is an open-flued, fan assisted downflow, ducted warm air heater, which may be supplied with SYSTEM E-T or
Basic control. A HIJAN 6 or SUPERJAN 6 circulator is available as an option. A pilot burner incorporating an Atmospheric
Sensing Device (ASD) is fitted which responds to the presence of flue gases and shuts down the appliance.
1.2 The Air heater output can be adjusted between 5.6kW (20.0MJ/h, 19,000Btu/h) and 7.3kW (26.4MJ/h, 25,000Btu/h). “Summer
air circulation” of unheated air is available by manual selection (see User’s Instructions). HIJAN 6 output is 3.81kW (13.7MJ/
h, 13,000Btu/h), whilst SUPERJAN 6 output is 6.0kW (21.6MJ/h, 20,470Btu/h).
