All right, so what we have going on today, um we went to uh it's just a backup source of heat, pretty much uh instead of but we have uh where's the central uh gas heating is our primary source of heat, but we just wanted to have secondary Sources and something that didn't require electricity, um gas is the only thing.

That's requires um raw natural gas or you can go propane either one, but this is one that we've already installed, and this is for our primary living space.

So uh they have three sizes, and this is actually made by ashley stove company, which is owned by usdo.

This is not sponsored video or anything like that.

It's just something that a project that we did thought we'd share it and how it turned out for us like.

I said it uses no electricity um.

So that's that's the big advantage that we went for uh and also, unlike the traditional uh freestanding stoves uh for for gas or what have you um or even uh, if you're, if you're doing a wood, stove or whatnot you have to have, you know basically a Chimney pipe of something to um, to vent upward um through your ceiling or or to do a into an exterior chimney, or what have you this doesn't require that the big advantage of the direct vent is it actually just goes straight through your wall, and it actually Uses outside air for combustion air.

The way it is it's a seal chamber, um, there's no exchange of of combustion gas into the house whatsoever, unlike um, say an unvented heater, uh or invented fireplace um, something like that.

This does vent outside and it actually uses outside air, so you're, not even using your inside air for combustion in a case like that everybody air that goes outside have to be drawn in from from outside to replace it, which will be drawn in cold air.

In the winter time, in this case, it doesn't do that it actually has a a basically a a pipe within a pipe.

So it draws in air the cool air from outside for the combustion air from the outside pipe, and it goes through the uh through the bottom.

Through the combustion chamber, you have a fuel rail across on the inside uh for your burner and then the hot air.

Naturally, rises on its own and goes outside through the inside pipe, and it just goes right out of your wall uh, and it was really not too bad to install we're going to show you how today, because we like this one so much we're actually going to Add a smaller unit in our master suite area to be able to have that backup source.

Just looking on some of the online reviews on this, i know there was a big concern from different people where they're questioning whether this had a fan.

No, it doesn't have a fan and that's actually a big advantage in it and that it does not require electricity.

That's that's the big thing about it.

That's what made us want to um to install this.

To begin with is that it doesn't require electricity um.

Does it need a fan? No it? Actually, it does not um.

It naturally circulates on its own because it obviously can't see, but what it's doing is - and you see some vents in the front here, but actually there's vents in the top that the heat is just like.

This is just the jacket that you're seeing um and then the heater obviously is encased inside uh, where the combustion chamber is, and so what it's doing is it's drawing cool air in the bottom and it's heating, the hot, the hot air, naturally rises out the top.

So it's going up across your ceiling, basically dispersing into the room throughout your house uh and, like i say with that that hot air is rising, it's pulling in cooler, air.

The coolest air is on the floor, so it's pulling that in um and it's just naturally circulating in the in the room, um and in fact um.

It was.

It was really surprising to me, like even even the bedrooms uh the doors you know for the for out of this main room um as long as you let the doors open, it actually heats them surprisingly.

Well also, now for a bedroom.

Obviously you know you might want to shut the door at night or what have you um, so you're not going to circulate that way.

That would that would be a problem, but um as long as as long as the doors are open, it does actually circulate into the other rooms.

It was actually surprising to me in fact, that it did that so well and you do notice like if i just walk from from this room and actually right now.

This is on this is what's heating today and it's about 30 degrees outside and it's very comfortable in here in the whole room.

It's not like it's just warm here and then cooler on the other side of the room.

Now it's actually um an even temperature, so so our house is 2 000 square feet of living space that we're actually eating.

Now, if right now, if you were to go into one of the bedrooms, it might be a couple of degree less.

You might notice a little just a little bit of change when you go into the rooms, because it's not quite circulating fully to that effect.

But now this heater is actually the largest one of the three choices that you have in this.

It is the dv ag 30 n, the n at the end, just means for natural gas um.

So you just have the natural gas option or the propane option.

So as far as these model numbers there's one misleading thing about it that i don't understand why the company did it but um, like i say you, this is the the 30 n we're going to install today up the 11 and uh and they're all dva g.

Whatever that is, but the 11 does stand for 11 000 btu input.

This one, however, was a 30 n.

It does not mean 30 000 btu input.

Strangely, it actually is 25 000 btu input just thought.

I'd make that a note, because a little bit misleading, don't know why the company did it? What about the thermostat? Is it just? Does it just stay on full flame until you turn it off or you know, do you just regulate the the gas up and down um what it does um coming in and i'll show you so you you just have like uh a setting um for you know.

So it actually is turning the flame up some when you, when you turn that up, but it in fact has a built-in thermostat.

So it's it's it's.

It's got a uh, a sensor on the bottom, where the air is coming in the bottom, and it's so it's attacked in the room air temperature before it heats it.

Basically, as it's drawing that room air in and it'll, actually once it reaches that set point which is not on a degree scale, it's just on the one two three four five um uh so like right now, um it's 30 degrees outside i've got it at about A three and it's keeping keeping it really uh comfortable in here, but you can always make that adjustment uh.

However, if it reaches whatever that temperature is that it's satisfied, it actually will turn the burner off.

So we decided, like i said, we're going to put one in the the master suite area of the house for the next one um and that's what we're going to start installing today and we're going to we're going to film all this we're going to walk you Through it, we're going to show you how to do it, it's really not that bad, but the first time i did this one just going by the directions it kind of it tells you how to do it, but then, like most directions, it kind of leaves a Lot of questions that are unanswered, we're gon na we're gon na address that all right, the one we're going to do today is the dbag 11.

This is the smallest one that they do.

This is 11 000 btu input, that's not necessarily the output, but that's the gas you're putting in because some of your heat is going to waste outside.

Obviously um you, never you don't you're not going to get 100 um, but you get you get close to it.

All right to show you the size difference, there's substantial size difference.

This is kind of like daddy.

This is kind of like baby, and then i don't have the 17 one um, the the metal guy, that's probably more like mom right, but we're gon na put baby in today, but the installation is exactly the same all right.

So what else is in the box? Here's the heater itself, obviously, but there's um parts to it.

So in other words, the heater itself has already comes pre-assembled.

That's great! I'M going to show you what else comes in the box.

So here you have a it's kind of like a a bracket thing.

So you you basically you're gon na you're gon na fold this down and it's gon na.

This is what's gon na go inside your wall.

Actually, that is just basically like a heat shield, because your combustion, air and flue gas is going to go through the the center kind of a vest going through your wall.

So this encases and protects kind of that heat.

It uh the the what heat does go outside um uh through your flue gas as going outside um this.

This boxes it in between uh between your wall studs.

This guy is is what the heater is going to mount to and it's going to mount to the wall, so this guy is going to he's going to screw on to the back side of that heater mount.

So that's going to go and this is going to go in the wall.

This is going to go flat against the wall and the heater is going to mount to these two top brackets and those two bottom brackets.

That's what's actually going to hold for the wall and then you're going to screw this into the studs of the wall.

So that's actually just going to be on the back side of the heater there.

Of course you have your mounting hardware kit, uh.

Just all your screws and stuff, this is what you're actually gon na see outside the only thing outside your wall is.

Is this part right here um - and this is what's gon na - go inside the wall that connects to the back side of the heater, and this is what i was talking about now they have.

They have styrofoam, like you know in here, ignore that, but this the black one on the inside is going to be what your, what your your combustion deaths, in other words after it's, went through the fire and has dumping that to the outside is going to go Through this guy and then your your your air intake, bringing the air from outside in to the combustion chamber is going to be on the inside the outside one, so it's actually helping to kind of cool some of that heat.

That's going through your wall anyway, because it's pulling in cool fresh air around the outside of that around you know this one being hot, this one being cool the cool is on the outside, so it's actually helping to take some of that waste heat back in to The chamber to give it back to your house in a sense, and it's also helping to not have so much heat in your wall.

They gave you this uh, basically foil, backed insulation that will go around wrap around this just to shield some of that heat as well just for efficiency and for shielding it out of your your wall, um, and then you also have this plate.

If you need for a combustible wall um, it's not necessarily, i think, on this one.

I didn't end up using this because on the outside, we actually have stucco that this goes out, stucco being non-combustible.

I wasn't too worried about it, but you also have this silicone.

Gasket that goes on the outside as well that you can.

You can seal basically back here where this is.

This guy is going to go against your wall on this back left um, and you can put that that silicone ring around it just to make sure that bugs or air leakage or something can't find its way into your wall, and that's it.

That's it for parts.

So the big, the the big thing is, is uh.

We're gon na we're gon na basically cut a hole in our wall um, it's just a matter of lining it up to the right place, cutting it out and take note of where your electrical outlets are and know that most likely there is a electrical wire running From outlet to outlet to outlet across between them through those wall studs.

So if you you might want to raise this up enough to avoid that.

But that's just for your hole that you're cutting, which is going to be towards the upper side of the heater, so make sure you check out the next video in this series.

It's going to be all about the installation so follow me over there.

I'll give you a link here, follow it over and let's go
