So I have my 25pvdc up and running. Seems to work fine after going through it though I have only run it for 3 hours due to the warm weather. As I hit the "ON" button and wait for the ignitor (i do actually have one) to do it's thing.... I was wondering..... Doesn't the ignitor waste electricity? Can I just unlplug it and manually light it, therebye saving some electricity? and oh yea, What the heck do the 3 buttons on the bottom do? Should I adjust them? How will I know if I should?
