" Well, let's meet Steve Bottazzi, a plumber."

" Hi Bob."

" I thought you'd be working up there cutting that vent pipe through. What's happened?"

" Well, we're positioning the vent because in this house here, we have two fronts for the house. We have a lakeside and we have a street side."

" And the pipe that comes through the roof isn't the prettiest thing."

" Right. So we're just trying to position it so it's not seen, trying to keep it out of sight."

" Under the- the edge of the"

" cheek wall"

" The cheek wall, good. Now how do you actually cut it through?"

" I'll take you inside and I'll show you."

" Okay."

" Alright Steve, so you're 24 inches off the cheek wall, but why are you gonna cut an oval."

" Because in order to put a round pipe through a pitch roof to have it come out straight, you've gotta cut an oval hole."

" There you go. Now let's go up on the roof and see how we make a weather tight."

" Okay, get that pipe out of the way Steve."

" Hi Larry."

" Hi Bob."

" Now what's that thing in your hand?"

" It's a roof shoe. It's designed to keep a piece of flashing that goes around the roof vent, so that water can't go down the pipe or enter the roof somehow."

" How do you install it?"

" Well, I've loosened up the nails in this roof shingles around the area of the pipe so that we can- we can locate it properly. Now what I'm gonna do is slide it up underneath and over the bottom force and Steve is gonna stick the pipe through and work it through slowly."

" So that rubber gasket makes it weather tight. You don't need any roofing cement?"

" No."

" And then you- you just put around with roofing nails?"

" So roofing nails at the top underneath- beneath the paper here."

" Right in to the plywood?"

" Right in to the plywood."

" [unk] hold it."

" Let's go right there. There we go."

" Okay."

" What about down here?"

" No. You don't put nails down here because the water, when it sheds up the roof, it's gonna hit the bottom in this metal and then back on to the roof and down and off."

" Right. That's all there is to it? You just put your"

" Basically I just have to replace the shingles around here and it's done."

" Great. Okay. Now why don't we go down to the basement and find out from Steve how he [unk] this plastic to the old cast iron. Anytime you're remodeling an older house, chances are you've got to deal with cast iron and plumbing pieces that wanna be connected to plastic pieces and how do you it, Steve?"

" Well we take a, it's called amana."

" Amana. This plastic joint piece is called amana."

" Right. And why do we need that thing?"

" It's a PVC amana but it changes from cast iron to PVC. "

" How'd you get it naturally?"

" We put oakum and lead."

" Okay. We just saw the lead."

" This is the oakum which has been around for centuries, and it's nothing more than jute, right?"

" Right. That's it."

" How do you fit it in?"

" Well we take it and we pack it. We put enough oakum in here that's why you've got about half an inch room for lead."

" So you're gonna wind around about three or four times?"

" Yes. Depending on the fitting, some it takes more"

" Alright, so now you have to fill it up with melted or molten lead, how will you keep the lead from dripping out in a horizontal situation like this?"

" We have what's called a joint runner."

" A joint runner."

" A joint runner which goes over the manoff or"

" Now this is a temporary thing, right?"

" Right, it comes off after it's been poured."

" Yes."

" You take the joint runner over the manoff."

" Clamp it shut."

" Make sure it's nice and tight."

" And what, that'll keep the lead from running out and you can pour it in through the top?"

" Through the top, exactly."

" Wonderful."

" So we take that, we take a little piece of oakum. Hold down here."

" Now let's talk about the fun part when you get to melt the lead, you've already got, oh this is, wait a minute"

" Yes, I've got some leftover from another joint I had done."

" I see and they're hard and dried up again."

" Yes."

" So how do you gonna melt it?"

" Well, I'm gonna take the torch and we'll just melt the whole thing. It will take a few minutes because the lead is still cold."

" Alright, it will only stay melted for a little while so here we go and you pour it right in up the top."

" Oh no as soon as it gets to the top and starts pouring out"

" There you go."

" and it's full."

" It's full."

" Now, how long do we have to wait before it's done."

" Well, it will take, let it cool like a half an hour because right now we've soften the [unk] plastic"

" Sure."

" And before we can pack that pack the lead right into the oakum. After 30 minutes Bob, we can take that"

" Yes."

" Let's see what kind of joint we have."

" The lead is hardened up."

" It looks good."

" So that's it?"

" And we pack it so that just in case, we won't have any problem with leaking afterwards."

" Okay, so you have to push it back in still farther."

Direct Vent Fireplaces for Heat and Ambience
Direct Vent Fireplaces for Heat and Ambience

Bob visits a Heat n' Glo showroom where Ross Morrison shows him a variety of direct-vent gas fireplaces. With a sealed glass chamber there is no interplay of of room air�no products of combustion will get into the room and it doesn't use any of the the room's already warm air for combustion. The fireplace inserts come with ceramic fiber logs. When the flames hit the logs they produce a nice glow. The logs are light, unbreakable, and last a lifetime. Ross shows Bob the 6000 TRXI, a premium model that is rated as a furnace. It has a beautiful masonry appearance inside and a pumps out enough BTUs to heat a 1200 - 1500 sq. ft. house. The fireplace also offers the option of turning the flames down or off or opening the climate control damper to cut the heat by one half.

Direct-Vent Fireplace Installation
Direct-Vent Fireplace Installation

Jack Murdock from RMI and Craig Ryans from Vermont Castings of Mississauga, Ontario, demonstrate how simple it is to have gas appliances and heat in a rural location. With a 500 gallon underground or exterior tank, enough fuel is stored on site for most common uses and requires just a few fill ups a year. The stove being installed, a Vermont Castings product, uses a direct vent technology that draws no interior air to aid in combustion. The unit pulls air in from outside through a cylinder pipe and releases exhausts outside as a typical furnace would. Gas appliances and heat function during power failures, although electric fans that circulate the heat will not work without an auxillary power supply. The fireplace installed in the Modular Mountain Retreat project home will provide 30,000 BTUs of heat. A realistic ceramic grate burner and ceramic logs enhance the fireplace�s look.

Multi-Zone HVAC System
Multi-Zone HVAC System

Bob meets with Mark Gallivan from Sears HVAC and Brent Morin from Morin Mechanical Services to review the heating system installation at the modular home project. The high efficiency, state of the art Hydro-Air system uses components of a traditional boiler, humidifiers, variable speed fans, electronic air cleaners and three exterior condensing units. Carrier manufactures many of the heating unit�s components including the boiler. The boiler produces hot water for both a forced air unit and a baseboard radiant heating system. The forced air unit allows for a consistent level of humidity in the house, that traditionally radiant-only units cannot accomplish, plus it receives the efficiency of radiant by employing a baseboard system. This gives the home�s occupants a more comfortable living environment. There are seven zones employed in the home�s heating and cooling system. The cast aluminum heat exchanger in this unit transfers heat three times faster than a traditional heat exchanger. The boiler uses a direct venting system that takes air directly from outside and vents it through a flue located in the center of the intake vent. This means no combustion gases are being mixed with the home�s interior air. The system�s zones can be turned on or off as needed, providing an added level of efficiency if the entire home is not being occupied at a given time.

Installing PVC Pipe
Installing PVC Pipe

Bob Vila shows a Victorian Style house where the rough plumbing is being installed. The house has a half basement with the remainder being just crawlspace. Bob meets Jim Timino the plumbing contractor who is running PVC pipe for the rough plumbing. Jim is installing a 2" waste line from the kitchen that will run to the main waste stack or piping. The main waste piping is 4" PVC and it runs into the sewer system in the backyard. Jim demonstrates how to properly cement or glue PVC fittings with the PVC pipe. They also take a look at the master bedroom suite, which will be magnificent because of its roominess and the extravagant master bathroom. They show the vent piping from the basement to the roof including a future vent that is required by Massachusetts Plumbing Code. The vent pipes allow proper drainage as well as a place for sewer gas to be expelled outside of the home. Bob tours the upstairs children�s bedrooms and overviews the header vent pipe and how it interconnects all the waste pipes in the home.
