Johnson & Starley ELJAN 4/SE Installation, Commissioning & Servicing Instructions

INSTALLATION, COMMISSIONING & SERVICING INSTRUCTIONS
This appliance is tested and certified by B G Technology for use with natural gas only.
IMPORTANT: These instructions apply to an ELJAN 4/SE that is either already fitted to a Johnson & Starley
HI-SPEC J25SC or SCS25 MkI air heater, or is to be retro-fitted to either of these appliances.
These instructions are to be read in conjunction with the relevant air heater Installation,
Commissioning and Servicing Instructions.
1.
1.1 ELJAN 4/SE is a gas fired circulator which can generate up to 62.5 litres per hour (13.7 gal/h) of hot water when installed
in a Johnson & Starley HI-SPEC J25SC or SCS25 MkI air heater in SE-duct applications. The appliance is suitable for use
in a fully pumped circuit comprising radiators and/or an INDIRECT cylinder. If the intention is to use ELJAN 4/SE with a
direct cylinder, then the local Water Authority should first be consulted. ELJAN 4/SE may be used in a sealed system
application when fitted with an Overheat Cut-off Device (CK1 kit).
1.2 The gas supply to the main burner is controlled by a multifunctional gas control valve. In addition, an electrically
operated solenoid valve is fitted to permit the main burner to be remotely switched on and off. The main burner operates
in conjunction with a permanent pilot burner and a thermoelectric sensing device. Pilot ignition is by means of a Piezo
unit.
