I'm installing a brand new minimax 100 heater. I have everything hooked up the way that I believe it's supposed to be, but I must be doing something wrong. Here's the problem... The pilot will light when in the "Pilot" position and when the knob is pushed down. When I start to let the knob come up to turn the knob to "on", the gas stops feeding through and the pilot burns out. I have kept the knob pressed down for plenty of time, so this isn't the issue. What could I have wrong? Is it the wiring that's mixed up? If so, can someone help me understand how the hard wiring works for this heater?
