  1. It all depends on how it was layered where we can't see from a picture. That will determine the answer. This can be a perfectly acceptable installation.
  2. This is a great question and it is not spelled out in the building codes at all. I was, however able to dig something up from New Jersey some time back (I don't know if they still have this language) but essentially they said that the outlet from the trap weir had to be at least 3" in length to be condidered a P trap. I have been using 3" as a decision maker ever since then but it is not in the IRC or IPC. Maybe Darren can dig this back up since he is a Jersey boy
  3. In this case it would be allowable to do this because you are now making the basement part of the thermal envelope. The only catch is that the space must be able to maintain a min. 50 F temp during the heating season and less then an 85 F temp during the cooling season in order to comply with the definition of conditioned space. This is becoming a popular method with contractors because they reported savings approximately 30% in costs vs having to insulate the underfloor and use the expensive 2" duct board.
  4. Good attempt Kevin, thanks anyway. Kevin, what type of construction do you see in your area? Crawlspaces or slab on grade? My area is split between basments and crawlspaces with very few slab on grade homes.
  5. Pulaski County is in zone 3 just as an FYI as far as the I Codes are concerned.
  6. You are doing phase insepctions on single family home in climate zone 5 currently under construction. During the rough electrical, plumbing and mechanical inspection you notice that the builder had the HVAC company install 1" duct board for the feed and return of the gas forced air heating system. On the 1" thick Knauf if marked R4.3. The installation is in an unfinished basement that is 75% below grade. When you question the builder about the R value and the fact that it will need to be R8, he replies to you that he will not be installing insulation in the floor framing. Instead he will be placing a pvc coated R10 blanket insulation on the basement walls from top to bottom and R19 against the rim board instead of placing R30 in the underfloor framing. Is this an acceptacle, code compliant installation to eliminate having to use 2" R8 duct board?
  7. Yeah that was a bad install. However, you should see the overhead from the pole to where they chose on the building. Horrible planning.
  8. And one currently under construction: There are LL's, LB's, TT's, etc for most 2 opening types.
  9. and more from a 2 unit
  10. Here is an LB on a residential new construction.
  11. You will find conduit fittings (mostly LBs) on many residential homes with an overhead service that use PVC to protect against physical damage. Very common.
  12. No riddle, I thought this was common knowledge. An LB is the conduit body that connects the conduit and has a cover on it. The LB conduit body creates a pull point. You took the cover off of it to take a picture. That is the LB.
  13. Not talking about the bushing, I am talking about the LB.
  14. That looks like a painted metal LB to me. Why does the conduit have to be bonded?
  15. I write 90% of the report on site but take it back to the office to finish. I e-mail the finished report to the customer the night of the inspection. They pay me at, or before, the inspection. Invoicing isn't reliable in this business. - Jim Katen, Oregon +1 on that. I do the exact same thing. The inspection agreement gets emailed to them the same day they book so they just show up with a signed agreement and a check or mail it if they are not coming to the inspection which is rare. It is best to meet your clients and bond with them.
  16. I only need a long lighter, a bottle of fish oil and some dimes to use as screwdrivers
  17. Unlike fuel gas in the previous quiz, an oil burning appliance will need two openings (or ducts) to the exterior. But since this is a simple question and I am only asking for the opening sizes we will not worry about ducts. One opening to bring in outdoor air will have to be located within 12" of the top of the enclosure and the other will have to be within 12" of the bottom of the enclosure. Since the openings will be directly communicating with the outdoors we will need 1 square inch per 4,000 BTUs of appliance input rating PER opening. Therefore, with a 60,000 BTU input we would need 15 square inches (net free air) per opening. So if you used metal grills with a 75% opening rating. Each grill would have to be a minimum of 20 square inches.
  18. Wow, we just asked the exact same question on the previous thread using a gas fired furnace and there was no shortage of supplies and a correct answer. What's up with this one?
  19. Les, you have all of the information to answer this question you need. Very basic.
  20. You are inspecting a 20 year old home that is not considered to be unusually tight construction. The family has recently finished the basment and has framed around the utility area creating a separate, nice size utility/mechanical room of 12'x12' with 8' ceilings. The room is sealed from the rest of the basement. All combustion air comes from within the room. In the room is an electric hot water heater and an oil fired hot water boiler for the hot water baseboard. The boiler has a 60,000 BTU input rating and a 52,000 BTU output rating. We now know that there is not enough combustion air available in the room. The boiler needs 3000 cu feet of combustion air and only has 1152. The homeowner has decided to bring in fresh air from the outside for combustion air. What size openings to the exterior are needed to accomplish this? Hint, this is now an oil boiler VS a gas fired boiler so the answer will be different than that of Quiz II. The point being we must pay attention to the type of fuel for several reasons. Good luck.
  21. The NJ HVAC licensing law does not differentiate between fuel oil and fuel gas contractors. My aunt in Navesink, NJ has a oil fired boiler.
  22. Come on energy star, go ahead and let us know the answer. The IRC Jersey version for the mechanical section is the same as the regular IRC for this question so it won't affect your answer. Learn me somthing.
  23. You know what. This has been a pretty good thread so I would like to continue it. If the scenario was exactly the same EXCEPT instead of a gas fired boiler, it was a oil fired boiler. Would the answer be the same? If not, why?
  24. Fraid not, never did. Thank you to all who participated and I hope that we all learned something from this. Jeff
  25. OK time to put this one to bed. Simple question and simple answer. What size opening (singular word btw)? 20 square inches for outdoor combustion air or 1 square inch per 3,000 BTUs. How can this be accomplished? How about installing a grill with a net free area of 20 square inches installed within 12" of the top of the enclosure. Don't read into the question. There are several ways to accomplish this but the question was specific to what size opening as in one opening. Jim K was able to nail it and give other useful and correct information first.
