Re: water heater installed right?
Not dribbling solder on a pipe! Might want to look over the water heater for fingerprints as well, the cad probably left some on it. I'd also search for any remnants of shiny marks around anything that took a wrench to tighten. |

said by tp0d :Tape is NOT certified by NFGC. There is no tape certified to hold to 400°F, this is why. Reading the NFGC I don't see where it states that the material has to be certified. It appears to be OK if the material is used in accordance with manufacturers recommendations. 3M Hi-Temp Flue Tape is recommended for use at temperatures up to 600 degrees Fahrenheit so it would appear to not be a violation of the National Fuel Gas Code to use such tape on a water heater vent flue. If they used sheet metal screws also then there would seem to be even less of an issue.

"Product Description
1-1/2" x 15' Hi-Temp Silver Flue Tape, Resists Moisture & Temperatures Up To 600 Degrees F, Seals Metal Flue Pipe Joints On Furnaces, Stops Leaks From Hot Air Ducts, Can Be Used Indoors & Outdoors."
said by tp0d :Sheet metal screws or rivets are the only certified method of securely joining flue pipe. Perhaps you should reread the code. Section 12.11.7 gives three methods for fastening vent joints and rivets are not even mentioned. |

If the "plum'mers mate" did that crappy a job on his Union Ticket Practical Test .. he would flunk !! Besides, this is a "paying job" and the installation must be perfect. Demand a "job clean-up"..it's been my experience with craft workers, that they are anal about perfection .. it's also thier ticket to getting $60 to $80 /hour labor rate on a paying job ! |

TpOd is right about the tape not being OK per the NFGC. I found the following on bradfordwhite.com, part of their manual for installing water heaters, so thought the tape is OK.
"WARNING All joints in the vent/air intake piping must be taped with aluminum tape at the completion of the venting system installation to prevent any possible leakage into the room. Make sure all the pipe connections are firmly pressed together so that the gaskets form a tight seal."
The tape doesn't appear to be on a bearing joint, so would lose function only if the adhesive gave out and it peeled away. It's around the vent where it exits the heater (straight up, out of the top) and may just be a topcoat for the main connection. But I want to be sure about that. (Is that clear? I tried sending the photo again. Uploaded a .jpg straight out of the camera, twice, and even changed it to a GIF, but DSL's website kept saying it couldn't find the attachment.)
Hello again, mityfowl. New York City requires a permit only if the combined BTUs of the gas furnace and water heater exceed 350,000. Everyone except one plumber (a large US chain) said I don't need a permit for this water heater, and I think the chain's rep was just trying to get an extra $400 out of me. (I tried to find out the BTU of my furnace, was unable to easily, so just figured it was unlikely to be 290,000. This is a furnace for a single-family frame house, 2500 square feet.)

Saying that the tape is not ok per the NFGC and then stating that the manufacturer instructions require it is contradictory to the NFGC. According to the NFGC 12.11.7 Joints ... shall be fastened... (2) By vent connectors of listed vent material assembled and connected to flue collars or draft hood outlets in accordance with the manufacturer's instructions. |

I think a modern home that size is about a 100,000 btu (forced air). I know mine is.
I do though have a 400,000 btu pool heater. When it starts up it's like a jet plane. |

Leander, TX | Actually it makes a lot of sense -- what the use of investing in a pool if you can't use it 2 months of the year?  |

Dallas, TX | With a little bit of planning a nice turn of the weather I can use the pool from mid April until mid Oct.
Now the reason for it is the spa. 12 months a year and it get hot fast! Plus I got a good deal on that size. |

You need to post these codes mentioned as "NFGC 12.11.7 Joints"! I found no such codes in the NFGC or in any plumbing code in NJ or any other state?
As for the solder drips; I would not except it! They are a sign of a poorly sealed joint! Possibly too hot or not hot enough? A properly sealed joint is clean and smooth!

| You obviously have not read the entire thread. To clarify, NFGC is the National Fuel Gas Code also known as NFPA 54. The code is online for anyone willing to take the effort to look it up. I posted reference to the relevant section and even quoted the relevant part.
Solder drips are a sign of using too much solder and do not indicate a poorly sealed joint. |

I can produce a master plumber with 40 plus years of experience that I work side by side with on some jobs who will elaborate on any code violation!
A poster who has already chimed in as a licensed plumber will also agree with my statements, I'm sure!

| I did post them. Let's see if I can say this so everyone understands. The code which has been repeatedly referenced throughout this entire thread is the National Fuel Gas Code which is also known as NFPA (National Fire Protection Association) 54. NFPA 54 is available for on line viewing on the NFPA site. Here is a link since you can't seem to find it

RISK OF INDOOR AIR POLLUTION AND FIRE. Be sure the exhaust pipe is properly installed and connected.

I have a hard time understanding that you were unable to follow the link I provided, however I will try to simplify it for you.
»www.nfpa.org/freecodes/free_acce···?id=5406
I cannot post a link to the referenced part of the code as the NFPA has the online code set up so it cannot be linked to. If you continue to have problems then I would suggest that you buy NFPA 54 and then you can thumb through a paper document and possibly read it that way. |

1 edit | You already stated that it was stipulated as code in "NFGC 12.11.7 Joints"! You need to post exactly where this is or you are mistaken and need to withdraw such statement.
As for asfgdhg-whatever? Posting what a lesser known hot water heater manufacturer excepts as code is not the standard!
