Whoich bit are you refering to? None of it looks like mold. It's chimney creosote.

You’re right it is absurd to open your window when you’re trying to heat your room. That’s why ventless fireplaces are silly. No contractor worth their salt should be installing them. They’re banned in California for good reason. It’s functionally identical to trying to heat your home with your stove.

You’re not “adding to” but directly contradicting my statement. That is completely fine and I’m not stranger to criticism but you should probably do some more reading on the subject:

(1) Modern gas fireplaces in the US are more likely to be ventless than vented.

(2) ventless fireplaces do not require an open window when in use. That’s absurd. Imagine opening your living room window because it’s 15 degrees out and you want to warm the living room while you watch a movie on the couch with your family or because you want an ambience on Christmas Day.

It’s all based off of efficiency which results in cleaner burning and less fumes.

To add to this: modern gas fireplaces are usually not ventless. This both sucks oxygen out of the room and expels CO. This is why ventless fireplaces and stoves require you to have an open window when it’s on. Modern gas fireplaces are usually DV (direct vent) which means they take in air from outside and vent gasses back outside. They will still heat your room, just not too efficiently.

Valid question I thought.

You can, but that makes no sense.. Why? Efficiency, money, time, amount of work. And in fact, if you ask 'Can I', it make much less sense in any attempts. No offense, but getting professional to suit your fireplace to work on gas or cooperate gas and wood (ashes in nozzles.. Yuck) will be !such more expensive than gettinfg professional installation with gas fireplace cost.

And in case of anything.. I know it's DIY subreddit, but some things are just too dangerous to mess around with them without enough knowledge..

To add to this:

Modern gas fireplaces are typically ventless and directly dump heat into your home. That will result in you heating your living room and sweating some people out but it’s not really a heat source to heat your home (like the above comment stated).

Your traditional fireplace should have a vent leading out of the home through either a chimney or metal pipe. Turning this into a gas burning fireplace would work but all of your heat is going to vent straight out of your home. (Again, just reiterating that it would be an even less effective heat source than a ventless, gas fireplace already is.)

Look for a professional

Either gas or wood, not both And yes, you can.

Just in case you meant using gas as heating source, that is not going to happen. Burning gas is used to heat water in boilers not heating up rooms directly, it's not effective.

Rude

Sometimes it’s better not to DIY.

The colors shouldn’t matter as long as each speaker is consistent.

If it sounds like the breakdown of “Life In The Fast Lane”, or if it sounds very thin when you sit in certain locations in the room, then one or more of your speakers is likely wired out of phase.

You can avoid brush strokes with a roller. They make mini rollers for small applications like this.

Fill with wood filler, let dry, sand down, apply paint with a brush, then go over that with a dry mini roller to eliminate brush strokes.

Or you could just paint it white and call it done. Maybe she'll notice. Maybe she won't care.

Scrap away any loose paint. Fill with wood filler, not plaster. Sand the filler, then paint using even pressure to avoid brush strokes. Avoid overloading the brush with paint for the same reason. Sand, using a fine grit sandpaper in between the coats of paint, and allow to dry. It should be perfect.

5.1 is five speakers and a subwoofer

The label says ps28. Looks like it's the back of the sub which the speakers connect to, and there's a separate DVD player. It does use an RCA to banana plug connectors, which could be hacked together from an RCA cable, speaker wire and banana clips.

How can someone not know that rcas are two lines?

Each speaker has 2 wires going to it, without exception. The rca jack is 2 wires in one plug, the center pin and the outer circular part.

If you cut that RCA cable and connect each of those wires to one of those bananas, that will work.

5.1 = 5 regular speakers = 10 wires total

If you don't have spare RCA cables lying around, you can get RCA connectors and solder/screw the speaker wires into them. See this and this.

It may not even be worth the money you'd spend on cables.

You do not want ventilation and that is not nearly enough spray foam to meet code in CO.

Wow, a lot of bad information here. You cant really go to school for home building so information gets passed down...

You want your thermal barrier and air barrier on the same surface. Previously that was the attic floor, now it is the attic ceiling.

The heat from the whole house is rising up through the vents, and that is pulling cold air in down at the low points.

You want to seal the vents. It might not be a bad idea to install a fan to the outside up there that can be sealed or a bathroom exhaust fan. Your house sounds unlikely to become too airtight, but if it did the answer is controllable mechanical ventilation.

I have a new house with a 200 amp box. By code it seems every room outlets, lights etc have separate breakers. It fills the whole box. It's stupid in my opinion. I also hate arc fault breakers too.
