@#$@#$@ stupid furnace installation people....

The pipe on the front slope may look better than the non-matching shingles that they will use to repair the hole in the roof.

The shingles (I have 2 packs) are from the original installation of two years ago. The photo shows the old roof.

Looks like you got the shingles covered. In the photo they looked faded from sun and weather. So, I thought matching might be an issue.

That's what I was thinking too. I thought the new high efficiency furnaces could vent directly through a wall, unless some local code prevents this?

they can. I had a 95% furnace installed in my basement and they vented out the side wall (I have a walkout basement)

Having a new, high efficiency furnace installed to take advantage of the tax credit (expires tomorrow). The guys needed to run two pvc pipes for ventilation and asked about the roof. I have the main roof and two peak, side roofs. I said if they could not put in in the back of the main roof, or if that was too hard, they could to the side roof and keep it close to the house. I told the supervisor that I do not want to see the pipes from the front. I just go out and they put the mother fucking pipe right through the front of the main roof. I even lent them a ladder and set it up on the side roof where it was to be installed. They climbed up the ladder to the side roof and then climbed from there to the main front roof.

Already called the supervisor and he is calling them. He knew exactly where I wanted the pipe(s).

FUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
😡😡😡
I will not pay them until this is corrected.

Sorry, but I need someone to rant to and ATOT is my choice!!!

LOL!

Did you spec the furnace for out put & total vent length of run (including turns, most pipe type single 90° turn reduce the length of run by 5' and so on)?

2 pipes for ventilations?
Don't you mean 1 pipe for intake and 1 pipe for exhaust?
And, the spacing between the 2 pipes must be at least 6'~10' pending design and local jurisdiction.

Plus the pipes must be a certain height over the roof line pending slope and local jurisdiction.

PS. What engineer would over look the above steps 😉

Not all furnace are direct vent.

Direct venting furnace design allows penetration though wall. Vent must be a certain distant from combustible intakes, other vents opening, windows & doors, therefore venting the furnace through the wall may not be possible.

This was an existing replacement. The original was a 68% (when new) efficient furnace. The new furnace is 95% efficient and uses two PVC pipes - one for ventilation (just a slightly warm vapor) and one for fresh air intake.

Don't you mean 86%, because sub 70% efficient furnace was pretty much phased out in the 60s. Unless you are really lucky to have one that lasts for so long.

There is a drop down ceiling in the garage over the closet (flush with the top of the door trim). They would have had to go through the door to get to the garage ceiling. It was a poorly designed closet but I guess they didn't think about the type of ventilation needed for newer installations. Oh, and I could not simply use the old gas ventilation pipe as the water heater still uses it.

The two choices that we discussed were to go into the attic above the garage, pipe up to the main attic (2nd story) and out the back roof. The other was across the garage and out the small side roof.

They took it up into the garage attic and straight out the main roof.

Regardless, they will be back on Monday to remove the pipe, plug the hole, re-shingle the area of roof where the flange is and then re-pipe over to the side of the garage to the side roof next to outside wall.

Distant from where it supposed to go to the closes window or door?

Is that a gas meter I sees?
How far is the gas regulator from the venting supposedly go?

Distant of furnace vent to the propose chimney top?

I have the manual and it clearly states 68% efficiency. It is 20 years old (actually, it's 19 years and 9 months).

LOL, I'm not a heating/cooling engineer. I didn't spec. any of it out, that's what I paid the heating/cooling guys to do. It's up to them to get it right as it has to pass inspection from the city when they get done or they get to do it all over again. I'm fine with it if they want to run them up through the back of the main roof and have better spacing and height on them. They just didn't want to run them up that high and into the main attic space.

Also, if you read, I stated in a later post that the 2 pipes were for ventilation and fresh air intake! 😛

I might be wrong. Because, Canada specially BC & I think California have pretty stringent AFUE rating.
