Top Tier owners - i need some help

So I bought a Top Tier from the LHBS that went out of business - it was his floor display I think? It is missing a bunch of parts to the burners, but he gave me a bag of stuff for a Natural Gas hook up. I assume i can't use this for propane? Any idea what the difference are?

Also if i want to add items like a Therminator and a Pump - do i need to order pieces to go in the T channel to hook them in the channel from Blichmann?

Last question is the guy gave me the bracket for a March 809 but i ordered a chugger pump - anyone know if i can use the same bracket for a chugger pump?

Thanks

Bracket should fit either pump. You can get the mounting plates from Northern brewer, moore beer, midwest supplies, etc. Google is your friend.

NG to propane requires different orifices. Then are you using high or low pressure propane?
