HI-SPEC J32P is an open-flued, fan assisted downflow, ducted warm air heater, supplied with conventional control. A
HIJAN 6P circulator is available as an option. HI-SPEC J32RP, which has an integral rear rising duct is also 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.
1.2
The Air heater output is 8.30kW (29.88MJ/h, 28,320Btu/h) . "Summer air circulation" of unheated air is available by
manual selection (see User's Instructions). HIJAN 6P output is 3.56kW (12.8MJ/h, 12,150Btu/h).
