My Grandpa gave myself and others an ancient heater

I love my Grandpa so much, and i have no system what I will do when he passes away.

I know that I should not believe about that, however I have trouble not thinking about sad things.

I try to spend as much time with him as possible while he is still here, and he has been quite sick lately, & I can tell that he thinks that he is going to leave us soon. He is trying to provide away a lot of things in his house. He is selling things that he knows his grandkids genuinely won’t want, & he is giving us the money. I know so bad for him, although he is just as jolly as ever. He invited myself and others over the other day, & both of us made the decision to go through a section of his garage, & he asked myself and others if I wanted anything in that section. I saw an ancient heater, & I asked him if it still worked. He was not sure if it worked or not, so both of us tried it out, then the gas furnace did work. I was a little afraid to take it because it was so old, however my Grandpa told myself and others not to worry about it. He said to make sure that I turn the gas furnace off when I sleep & when I leave the house. If I only use it when I am awake & at the house, he said that I should not have any concerns. I hope that he is right because I have regularly been afraid of using space heaters. I know like I am going to catch my condo on fire. I know that it is possible, however if I use the gas furnace the way that my Grandpa suggested, I genuinely won’t have any complications with it.
