15. Стр. 15 Burners are controlled by the spark

    electrode, flame sensing electrode, gas valve СУ! and combustion air fan B6. The spark electrode, flame sensing electrode and gas valve СУ! are directly controlled by ignition control A3. Ignition control A3 and combustion air fan B6 are controlled by heating demand from the thermostat or control…

16. Стр. 16 А "Fenwall" electronic direct spark

    ignition with flame rectification sensing is used on all GSIG6E units. The "Fenwall" control is illustrated in figure 10. The 4 wire harness, plugged directly into the jack at the lower corner of the control, is used to connect the control to the unit. Each of the four jack terminals are identified…

    open to de-energise the ignition circuit and terminals 1-2 close to energise the fan. The limit is factory preset to “erip" at 65.5°C 3°C (150°F — 69Е) on a temperature rise and reset at 43°C 4°C (110°F 7°F) on a temperature fall. This is a safety shut-down function of the unit. Primary (lower)…

20. Стр. 20 If flame is not sensed after first trial

    for ignition, controller A3 repeats steps 6 through 10 up to two more times before locking out delay relay K25 waits 60 seconds. If the control locks out, it can be reset by breaking and remaking thermostat demand. 11. After 60 seconds delay, relay K25 normally open contacts close. 24 VAC power is…
