I'm living in Mexico and my landlord just installed a new boiler.
When it's turned on, it makes this huge noise. When you check the burner, you can see this flame below the main burner.
I asked my landlord about it, and he says it's normal, that the loud noise is simply because he turned in burner pressure to all it can be. (I'm not convinced it's normal, but he's stubborn about it)
After he left, I left it like that for a while and then checked the burner again and I see the burner metal glowing red from the underside 'cause of the flame that ignited there. This can't possibly be normal operation, right? So I lowered the main burner pressure (to the minimum) and it still ignites a flame there.
I'm wondering if I'm missing a gas pipe connecting the main burner and the pipe that extends from the control unit… but the few pictures that I've managed to find of similar models of boilers seem not have a pipe there, either.
So for a proper question: what do you suggest I do to fix it? (besides hiring a professional to take care of it for me, as my household is living on just savings right now, I can't afford one and, besides, I'd also like to know 🙂 )
BTW, I've been Googling around and am surprised to see that it's difficult to find the type of boiler that I use. This is the type that you find all throughout Mexico, but all I see in the internet are these rectangular-looking ones.
Here are the pictures for my boiler.

You don't need to do anything, the burner configuration, while a bit crude, is as it is intended. This kind of burner configuration is notoriously loud. I have a small portable camp stove with this configuration that is named "Pocket Rocket" due to it's loud roar when burning.
The pipe you often see that appears to be missing will always have large air inlet holes to meter the mix air. Without this, the mix air is metered by the size of the lower plate's center hole, which is not very accurate, evidenced by the orange in the flame. You will notice burners with more sophisticated mix air metering will burn pure blue.
The glowing red is not unusual either, it's simply a lot of heat in a small area.
