Braemar Fault Code 08
Fault: PS condensate closed at start
Potential Cause (Technical Use Only: Potential remedy):
Faulty condensate pressure switch – contacts stuck closed. Check pressure switch – replace if required.
Condensate blocking suction hose to HX drain pan. Check suction hose – clear condensate blockage if required.
Condensate pressure switch suction hose squashed. Check suction hose – re‐route if required.
Fault Code 11
Fault: Flame signal lost due to permanent or intermittent fault with flame sense lead or electrode.Incorrect test point pressure.Incorrect gas supply pressure to heater.
Potential Cause (Technical Use Only: Potential remedy):
If there is no obvious reason for the thermistor temperature being > 60oC when starting, such as a power supply interruption, check the following:
Check flame sense lead is connected securely at ICS.
Check flame sense lead is not damaged or shorted – replace if required.
Check flame sense gap – should be 4‐ 6mm from flame sense electrode to burner face.
Check flame sense electrode is clean – clean with steel wool or replace if required.
Check pressure at outlet pressure test point on gas valve – compare with value specified on data label.
Check supply pressure at inlet pressure tapping on gas valve with heater on max and all other gas appliances running. -NG – minimum 1.13 kPa. -Propane – minimum 2.75 kPa.
Check gas meter regulator outlet pressure and fitting line size and length. |
