1.1
The Johnson & Starley JANSTAR is a all mounted, room sealed, fan assisted, down flow warm air heater with SYSTEM
E-T control. It is designed for use with a concentric air inlet/flue, which enables combustion air to be admitted to the
burner, whilst combustion products are discharged to the outside, via a concentric terminal.
1.2
The air heater output varies automatically between 8.0 kW (27,300Btu/h) and 2.0 kW (6,800 Btu/h) for horizontal flued
installations, and 8.5 kW (29000Btu/h) and 2.8 kW (9600Btu/h) for vertical flued installations.
1.3
The appliance is supplied assembled for left hand return air entry. For conversion to right hand return entry, refer to
Section 4. If return air is via the top of the fan chamber, a side blanking plate (Pt No W800-0133000) is required. An
adaptor kit is available which permits the appliance to be converted to an upflow model. The appliance may be base duct
mounted. The JANSTAR is also provided with the facility for connection to a remote time control (not supplied), with
volt-free contacts (i.e. The switching supply is provided by JANSTAR), to enable selection of operating times.
1.4
A mesh filter, for air return duct mounting, is supplied as standard. However, a Cleanflow electronic filter is offered as an
alternative option.

ZZ757/9 5.1.2 The return air system should be constructed of fire-resistant material. It is extremely important that the correct size of return air grilles and ducting is used. The return air duct size should be NOT LESS THAN 225mm x 200mm (9in x 8in). - Page 4 ZZ757/9 6.2.9 The flue/air duct spigot on the appliance is female. For horizontal flued appliances, the flue/air duct should be constructed that such that condensate cannot leak from the joints. Therefore, on vertical runs, all female ends should face away from the appliance, and on horizontal runs should face towards the appliance, as depicted in Fig.
- Page 5 ZZ757/9 CONDENSATE 6.3.1 When firing at low rate, the unit will produce condensate which must be drained away. A JDT1 kit, which externally drains the condensate away from the flue terminal is available for horizontal flued applications. Vertical flued applications require the fitment of an in-line condensate trap within 0.5 m of the unit, in the first vertical flue run, and before any bends in the flue run.
- Page 6 ZZ757/9 7.6.1 If the burner fails to light (amber ‘LOCKOUT’ illuminated): Reinstate the ignition sequence by allowing 10 seconds to elapse, and then press and release the ‘RESET’ button. 7.6.2 If the burner ignites but then extinguishes: An automatic purging sequence will take place, which lasts for approximately 30 seconds.

ZZ757/9 10.4 GENERAL INFORMATION: 10.4.1 This appliance is fitted with an automatic sequence control which also provides a spark ignition and flame detection facility. If the ignition/detection electrode fails to detect the presence of a flame during normal operating conditions, it will cause the multifunctional control to close. The control will then make one attempt at re-ignition by repeating the pre-purge/ignition cycle and then lock out (indicated by the amber light). - Page 12 ZZ757/9 AIR CIRCULATION FAN CONTINUES TO RUN OR CYCLES BURNER NOT OPERATING WHEN BURNER IS NOT ON Check that the time control is on and Thermista-stat is calling for heat. Check mains electrical supply. Check that Thermista-stat is not set to ‘Summer Airflow’. Disconnect Thermista-stat at terminals 3 &...
