Buderus G115

hi on the g115 model 28 the d.o.e Heating capacity is 98,000 btu.

my load is about 53,000. but next year I want to add indirect water heater and in 2 years a small addition on the house. if I have my contractor remove the baffle plates and put a smaller nozzle on the burner. will that bring me to around 78,000 btu.

and next year when I add my hot water heater I can have them put back in to bring it back up to 98,000 I just don't want to short cycle the burner this year.

thanks
