vulcan powerhouse central heating - cutting out
hey all,
we have a vulcan powerhouse 80 central heating unit, model: 9047.
the problem,
turn it on in the morning and it runs perfect for the first 2-3 hours then the flame cuts out and the fan keeps going, will not turn off unless you cut the power i.e. pull the plug.
while fan is going, turn the thermostat off and on again after about 10 mins and the flame comes on and you have heat but it blows cold again after 15odd mins, you do the same thing again turn thermostat off and on with 10 mins in between and again heat for 15 mins and so on.
any help is appreciated.
