I'm putting my boiler ring together and I'm wondering about this



Probably a stupid question but I'm assuming I need to close that up?

Use it to control oxygen flow. With more oxy you'll get proper 'blue' flame and higher temps. Mine is fully opened.

See I thought it might be something like that but I haven't a clue really. Thanks.
