i wanted to follow up with a pic. if you are going to drill holes this is about where they should be on a mendota dx model .They should be smaller in diameter than the main burner and in a straight line directly covered by the pilot flame. i marked them in white on your picture whever the center of the pilot flame hits. maybe half way down from the top of the burner. i agree with you that when you buy a supposedly quality unit you shouldn't have to modify it to try to get it to work safely. I feel sorry for the people who don't have mechanical skills. i hope this helps. good luck.Hi!
I started having problems with the exact same unit as the OP (Mendota DVX45). We bought the unit in 2018 (converted to LP) and used it about a half a dozen times that season because it was installed mid-season. Last year it started with the small explosion. Talked to the place we bought it which is about 2 hours away and never got the issue resolved. I blew out around the pilot hood and it seemed to help. This year- I cleaned the unit and it started up fine. I set the pilot light to stay on and tried it about a week later and whoomf- back to the same thing.
I looked at this thread again and I see a difference in the picture in thread #7 and the pilot hood compared to mine. His setup is different to where it appears the pilot flame is directed at the TP, TH and the burner. Mine's directed the two thin wires and a gas log- not the burner. Is this a faulty conversion done at the dealer or is this correct?
Here's a link to a video of what was happening last year. The same thing is happening now but the pilot light is also being extinguished half the time. The unit then locks me out and has to be reset in order to start the pilot light. This doesn't happen every time but it is happening. Here's a link to the video- Mendota. That fireball is loud and freaks me out when lighting it as it sounds like the whole unit is going to explode
The dealer suggested drilling a hole in the burner closer to the pilot light- I'm now thinking this is an incorrect conversion or pilot assembly. Any suggestions?
Does anyone know how to remove this pilot hood? I'd like to get it off to clean it if possible.
