responses appreciated for the following problem-
according to the schematic for the flexiflue in the installation manaul (WHICH APPEARS TO BE WRONG!), relay 1 holds the pilot light on through the thermocouple and theroelectric valve and relay 2 (puled in) when no pressure drop is sensed. when water is drawn, relay 2 should drop out and the pressure switch should change contacts holding relay 1 in.
the problem i'm having, is the pilot wont stay lit when water isnt being drawn due to relay 2 not pulling in. the fan speed will change to high, the pressure switch activates, but according to the drawing (WHICH IS STILL WRONG....) i'm not getting the 130v across relay 2 that i need to pull it in.
has anyone had this problem before, or has anyone got a CORRECT schematic diagram to assist in correct fault finding!
incidentally, if hot water is drawn, relay 1 pulls in (due to the pressure switch changing contacts and relay 2 is already in its de-energised state) and the pilot light can be lit and the water heats up. soon as the taps shut off, water flow swich closes, shuts fan to slow, pressure switch changes, relay 2 dont do owt, so relay 1 drops out and pilot goes out.
technical talking point if nowt else, tho its damned annoying.
cheers,
nrg
