adding a condensate pump.

CHAC Member Posts: 1
I have an existing Weil Mclain EGH-85 steam boiler connected to a 2 pipe system with F&T traps. I will be replacing an air handler in the boiler room  and adding a steam preheat coil to the HVAC system. the  new preheatcoil has a BTU capacity of 184MBH with a condensate load of 191 lbs per hr.  the issue is the return from the steam preheat coil will be below the water line in the boiler. A condensate pump will be required correct?  Will it be ok to have a condensate pump only from this coil and still have  gravity returns with F&T traps for all the other returns lines? can this greatly increase my chances of flooding the boiler when the pumps runs ? would I have less of a problem if i drained all returns in to larger condensate  pump?

Thanks in advance
