Gas pipe manifold pipe size is 3/4 " , should be 1/2 "

II just received this range and IT IS suppose to have a 1/2 " gas pipe for the manifold for the cooktop. The pipe is 3/4 " and I can not fit the 3/4 " fittings in the back without relocating the cooling fan on the range ?

    My range came with a 3/4" gas line for the cooktop. The manual states it is
    1/2" . It even comes with a plastic bag taped to the gas line with a 1/2"
    90 degree street elbow inside with instructions that say to use it on the pipe ?
    there is very limited access on the back of this range and it is impossible to use any 3/4" fittings on this range with out removing one of the cooling fans. I do not believe I would be able to reinstall the fan after the fittings would be installed.I can not get a answer from anyone about why it does not have a 1/2" pipe like the manual states. For the money I paid for this range I feel I should not have to relocate cooling fans to hook up a gas line. Does anyone else have this problem or is my range the only one like this?

The manual says the pipe of the internal gas line is 1/2 and the external line 3/4 flex gas line :
Use 3/4" flex line to connect between the gas supply and the appliance manifold
pipe, which exits the upper rear of the appliance on 30” and 36” ranges. The appliance manifold pipe connection is 1/2" NPT. Use caution to avoid crimping the 3/4" flex line when making bends.
Suggested length of flex line is 48";gas pipe manifold pipe size is 3/4

Use 3/4" flex line to connect between the gas
supply and the appliance manifold pipe.

i did download an installation manual, didnt have your model but checked a few and seemed to be the same. asking that you install the supplied pressure regulator, perhaps you didnt install that and thats where the pipe sizing diff is.

Hi, I guess you question is how to use these pipes.
You can use manifold pipe adapters/ fittings which can connect pipes of two different sizes.
I can look for one if you can tell me about the pipe. what brand is it? did you get it along with the Cooktop ?

Thanks, :)

Hello,

You can buy gas pipe adjuster from 1/2 to 3/4..however you can buy 1/2 gas pipe in any vendor of the range.

gas pipe adjuster is the solution.

Raptor 660 backfires and pops


Hi mate most common setting on almost all carbs would be 1.5 to 2.5 turns out. if runs better with less turns out than this range, then you need smaller pilot jet, or if needs more turns out then 2.5 you need bigger pilot jet. The glowing red header pipe is normal every yamaha I know will do this especially if left to idle for more than a minute... Regarding issue of popping this nearly always due to lean pilot circuit. first step clean pilot jet and or up size your pilot jet 2 or 3 sizes. just to clarify the turns out procedure make sure you are counting a full 360 degree turn out as 1 turn. I have seen in the past guys adjusting this air/fuel mixer and counting 180 degrees as 1 turn out needless to say it don't work... cheers mate hope it helps

What does a F12 error indicate on a Noritz system


F12 occurs on a multi-system or quick connect. It means one of the units on the system suffered a flame loss. More specifically, it means the flame rod stopped detecting flame on the burner. The most typical causes are as follows:

1) insufficient BTUS (low gas pressure)
2) leaking heat exchanger
3) clog in the manifold, burner, or heat exchanger
4) stuck flue damper or improperly sized venting
5) dirty flame rod
6) damaged circuit board or gas valve

6 burner propane fed will not allow all burners to produce a usable flame for cooking,grill is not hot enough


I need more information, but I suspect you may not have a large enough regulator on your propane line. The only way to know for sure is to attach a gauge called a manometer onto the manifold that feeds the gas burners. There is a 1/8 inch pipe fitting on the manifold for this purpose. It should read 10 inches of water column. You need a capacity to run about 300,000 BTUs when everything is on at the same time. This requires a large capacity regulator. Also the line from the regulator to the range should be at least 3/4 inch pipe.

I am purchasing a home with a kenmore elite gas range model # 790.3670--the seller doesn't seem to know if the oven is electric or gas. What is standard?


Electric or gas would be standard. If this is a stove like in the picture you provided, and is gas on top ... it is probably gas inside. You could always look to see if it has a burner or a calrod. See if there is a setting for Pilot or Igniter. Electric ovens don't need a pilot nor an igiter.

Of course, you could turn it on ... or pull it away from the wall to see what the connection is ... gas pipe or, if electric is involved, a very heavy electric cord - probably 50 amp 220 volts. If it has a small cord plugged into a standard wall outlet ... definitely gas fired. You say the top is gas so there will be a flex pipe for the gas ...

I searched Sears - they claim there is no such model.

Your agent should be able to tell by looking.
