My girlfriend and I just bought our first house and it uses a Olsen forced thaw out air furnace. It hasn't be unsed since last winter. The bubble valve is set to instigate and it uses a sparker system for starting. When I flip the power switch to on then move the thermostate to purely over the room temperatue mark . All I hear is a clicking reverberation. I don't wan to blow up the place so after only 20 second I turned the thermostate back bad. What should I do?
Answers:    you have to table lamp the pilot light first which is lit by the sparker system but to be honest if you enjoy never done it before you are better past its sell-by date to have a professional come surrounded by and light it so you do not blow the total house up
If you have a spark igniter afterwards you don't have a pilot pale. When it turns on you will hear some noise and the newer ones enjoy an internal evacuation fan which runs for almost a minute before the gas turns on and ignite.
