A lot of those units called for 12" WC on natural gas.  I have had to change the fittings and the hose size on the enrichment solenoids to get more gas flow while cranking on systems where I could get 12" WC on the gas supply.

My MIL is circling the drain and when she goes I'm going to get a nice water cooled unit.  I've been planning her demise since I met her.  Tried spraying her with water but she didn't melt.  I have 2# gas going to my 22kW (regulated down to 7").  I couldn't find the QT08045 on the internet, what size is it?  I've got my cold black heart set on the RG022.  I just splurged for solar and powerwalls so I have no money left.
