blue ox co2 burner

i was given a blue ox co2 burner with 8 burners and only 5 work. Anyone know where the cheapest place to get replacement burners is . Also ive ordered a matador controller but for now, what would b the easiest way to test co2 levels in the room.

is there a downside to only running the 5 burners rather then the 8 its a small room and it runs like 3 min an hr for 1500 ppm, i went and got a co2 injection test kit and im wondering if i even need the matador controller.

Yea if the other 3 burners aren't lighting then they might be putting raw propane out into your room. They might be just plugged. I would check that first before I replaced them.
Send an email to the company. http://www.blu-ox.com They can tell you forsure if you can replace burners, or give you an idea of how to clean them.
