Hello people! I need help as soon as possible because I am about to buy a USED 5000 calorie Martiri stove and when I asked if I had an exit to the outside, he replied: "It comes with both systems, I had it running out" My question is: Are there stoves that bring the possibility of changing the system or does someone modify it? I understand that a stool balanced shot improperly installed or modified can explode and also that they only come with a single system. I await your comments, I have to go see her tomorrow. Regards

Hello There is no such duality, or it is balanced shot (which wears a hat outside to take air for combustion and to expel the fumes) or is without a "catalytic" type outlet (which catalyzes carbon monoxide converting it into dioxide) that does not You can install indoors and much less in a bedroom. Do not risk your life for a few pesos, buy an appliance in an accredited business and have it placed by a competent gasist. Cheers !
