Hello all,
Something that needs to be considered when adding a fuel burning heater to a room or house with existing gas appliances is combustion air...you could light your stove and have your water heater go out, cause the stove is sucking up all the available combustion air! Or worse, have the negative pressure pull flame into the house from the gas water heater with serious risk of fire...I kid you not, I have seen it happen!
Happy heating!
Bud
