Replacing old an old stove/heater with new unit

[Max Denning]

Hey all, just picked up a 3 family in Worcester, Massachusetts with some old appliances. The tenants are currently having issues with their old Caloric combo gas range/heater. It looks very similar to this style oven. Essentially none of the igniters are working on the stove top. I'd rather replace it than find someone willing to work on these things, they just seem like a headache.

My question is, can I just split the two apart by buying a new natural gas oven and putting something like this beside it? Anyone aware of any MA laws against doing something like this? Thanks!
