Question about Procom MN100HPA Heater
I have a 3-plaque propane heater similar to the 5-plaque MN100HPA. Don't remember the mfgr, may be Procom. Manual heat control. First plaque lights fine. ~50% of the time the other plaques won't light properly. When valve is advanced to light 2nd and 3rd plaques, I get a big Whoosh! and the flame only flutters at the top of the plaque, while the unit releases a lot of raw propane. Takes many retries to get proper ignition and uniform heat. Doesn't seem to have excess pressure, and works fine after proper ignition with any number of plaques burning.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

You may want to try Master Parts, they may have the plaques. The problem with replacing the plaques is that they can be expenise to replace. Sometimes its the same price just to replace the total unit.

I had this problem. From using the center brick most of the time, lots
of dust bunnies build up in the gas chimney behind the brick.
Tie 2 pipe cleaners together with a small perpendicular circle at the top and carefully remove the dust bit by bit by twirling the cleaner.
The brick should fire like new if it is carefully cleaned out.

It sounds like a delayed ignition- and YES!-- that could be dangerous if something flammable was nearby, and no one was around to make sure the fire did not start something int he room on fire!
Trouble shooting delayed ignition:
Does this heater use a glowing ignitor to ight?
Or a standing pilot?
Or a spark?
I suspect that whatever is supposed to light the gas burner, is not in the path of the first gas release, (when the gas valve Opens) and so it takes a bit for the gas to build up, and finally get around to the source of ignition-- and then WHOOSH!!-- all that extra gas ignites!
Can you see the ignitor as it goes thru its first firing cycle-- what do you notice about the ignitor?
Something to consider:
What prevents it from filing the room with gas, before it ignites!
Sounds mighty dangerous to me!
Let us know what happens, and what you find-
