    Not happy with this unit.

    4 months ago
    After connecting this unit to propane, the pilot would not light. I removed the front and found the wire to the pilot button was disconnected. After reconnecting it, the pilot lit every time but I could not get the main burner to light and called for tech support. After talking for 10 minutes and trying several things, I was told to send it back to the factory for exchange. I'm still waiting for the new one.
