[VAC] Suburban Furnace replacement?

Title: Suburban Furnace replacement?

I'm need to replace my Suburban model NT32FCA. 
The label on it says "30000 Input BTU per hr"
and also "24000 Bonnet cap BTU per hr". 

What's the current model line's equivalent --
the NT-30SP, the NT-24SP, or what?

Thanks,
