pocono 90k burner

i have a pocono 90k unit in my basement.....when i was cleaning it this summer i noticed cracks in the burner plate that run parallel with the sides of the stoves, from hole to hole. Is this normal, or should i replace it? Thanks!

If just hairline cracks in the metal and don't go all the way thru, that shouldn't cause any problems. its just combustion air coming up thru. The grates are usually pretty thick.

Can you email me a pic , leisurelinestoves@gmail.com . Thanks ,Dave
