Ok, imagine it:You're at a party with a bunch of your friends. You're with a lot of people but it's a reasonably quiet party. You're all hanging out in the hot tub, when you hear a disturbing noise from inside the house. Kind of like 'OH YES! YES! OH!' and a lot of moans you know what I mean. So you all go inside, all of you thinking 'wtf?' so the noise leads to the master bedroom with a double-bed inside. Your friends push you forward and decide that you should be the one to open the door. When you eventually open the door, you see two girls 'at it'. What would you do?[the girls are super-hot btw.]
It' a test U need to pass read the book as us answering it will not teach U anything. good luck.
Well if I HAD to guess I would say A. B, C, and D would certainly all merit one, but an outboard motor doesn't present as much of a risk to the vessel and may not require the unit.
It depends on what you have. the main thing it that you have a good tight seal in the flue and that the flue can take the high heat going up it. the gas insert flex tubing won't work because over time it will burn up and you can get a fire in your wall and burn the house down. It would be better if you had it installed by a pro and inspected by the fire department so that your insurance can cover you in case something happened. I know it sounds like a hassle but you should do it right the first time and not learn the hard way. talk to you fire department and ask them, because they are the ones who see this more then anyone. Get it certified to code and teach everyone in the house what to do in case of an emergency. Have your fire extinguisher ready away from the unit so you can get to it and not be in the hot zone. have two or more in your house and garage. They are very nice to have, but they can be very dangerous when people don't know how to handle them, remember, it is a fire going inside your home. ask the fire department for recommendations for a certified installer.
