Hi guys. I'm in the process of installing a hydrogen co2 generator. I got the natural gas one. How are you guys patching into the natural gas at your location. I was thinking of splitting off the line going to my water heater. It's about 2 feet from where my co2 gen is going to be located. Any input or photos would be appreciated. Also, if you could let me know where you got your parts to do this...

Hi rr14,
WOOT, you got one!!
If you dont mind, could you tell me a little about the way they shipped it and packaged it up, is it a discreet package?
Did you get the mini icecap or iceboxes as well?
Im sorry i cant help with install,

o.k. ya little wankers this stuff is easy peasy.I ran fourty feet with multiple 90 elbows,nipples,couplers,and gas shut off valve.
1 crap you need no if ands or butts :1 either two pipe wrenches or 1 pipe wrench 1 vise grip.
2 tfe doping compound make sure has teflon
3 all water heaters run off 1/2 inch pipe so you will need if your are running from,water heater 1 measure in inches from cap section of t fitting where you want to run your new line from.allow for door to close over pipe so route pipe to bottom of door on inside if possible if not try to plan route with door being able to open close.if you do not have a t fitting with a cap for a new access line you need to figure out where you want to run your new line from existing nat gas line.1 turn off gas remove with pipe wrenches remove a length of existing nat gas line between a coupler or elbow fitting (elbow being an L shaped fitting) replace elbow with 1/2 inch T fitting to allow a new gas line.
4 plan your route keeping at least within 2 inches next to wall for safety reasons.Is it a straight run out ?do you need multiple elbows and smaller lengths to route out bottom of water heater door?
5 brass gas shuttof valve should be run before low pressure gas fitting that your nat gas generator comes with so end of pipe run shut off add a coupler run another section of pipe to low pressure gas fitting.
6 clean threads of pipe thouroughly apply tfe dope compound completely around threads ( no bare spots dopey) hand tighten .
7 move out from the beginning of your new line with appropriate sized elbows(corners) appropriate sized nipple (for right distnce between elbows to maint 2 inch distance close to wall.
8 after hand tightening your first run from new line take pipe wrenches in a V pattern around pipe and tighten at least one full revolution.your pipes and elbow don't line up after tightening one full turn keep tightening untill your pipes and elbows are lined up wher you want go o.k.
9 o.k. your oute is done you have putin gas shuttof valve and are ready to put in low pressure gas regulator cover threads of ipe with tfe as before hand tighten untill unable to tighten further and applying pipe wrenches i aforementioned v formation tighten one full turn.
10 thread low pressure gas line onto fitting from pipe and run to gas generator.
11 saftey check all connections with a mix of 25 percent dish soap 75 percent water.pour over all unions and check for leaks if so tighten with pipe wrench.
12 biggest thing shuttoff gas,apply tfe to all threads,tighten appropriately.and you should have no problems.
anything bigger than 1/2 pipe and p.m me and ILL get back to you

all of your nat gass appliances have a safety shut off a brass valve with red twist nob when parallel with pop its on if you have a square peg turn counterclockwise untill shut off.now you should check the pilot light of your waterheater,stove,furnace,run dryer if nothing warms up after 5-10 minutes gas is off.allow a minute or two for pilot light to die if so your good to go and you can open up line after shuttoff valve.if pilot light is still on gas is still present check valve if something is defective you need to find your main gas
shutoff turn off and replace defective gas valve down line.
after you have done everything correctly in my aforementioned post and gas
is turned on make sure to relight any pilot lights you have shutoff from your work.
also all threadings should hand tighten after cleaned easily DO NOT FORCE!
go back do you need a nipple ?a coupler? an elbow against a nipple against an elbow? to route your run?
anything below 3/4 need only have threads of pipe applied with tfe pipe dope,anything above needs to have threads on pipe and couplers doped completely! no bare spots!
also 1/2 inch pipe is suffecient for low pressure gas fittings for gas pressure drop.be aware if you run 3/8 nat gas pipe to a larger nat gas generator you might have insuffecient gas volume c.f.?i forget gas measurements,but their are gas ratings usage for your device ,that you need to calculate if you are using a larger generators it's the gas ratings are similar in theory to voltage drop,and proper sized wiring.most not all water heaters need 1/2 inch gas pipe because of amount of gas used,same with dryer 1/2.
a furnace might need 1/2 3/4 inch meausre pipe diameter.
1. one final safety note and I m done when your main gasline comes into your house it has a first stage pressure regulator.probably somewhere after your main gas shut off. I dunno exactly. rule of thumb don't run a new line before any prexisting aplliance as it may be before 1 st stage pressure regulator.other than that plan it so wife kids roomates are gone so they don't
interupt your work with complaints,perhaps interfering with your train of thought safety.

The HydroGEN Natural Gas is shipped with NO HOSE at all.
It has to be "hard plumbed" to the gas line.
Black Iron Pipe is what I used.
That would be my suggestion to you as well.
Remember to start at the beginning and work your way forward to the unit, as all the fittings have to be threaded together.
Good Luck

NO!unsafe the flexible hose at the back of your appliance is not meant to carry gas before a shuttoff valve.they also are thin walled have tendacy to deteriate over time of if moved.
use only black or galvanized pipe meants for carrying nat gas.now flexible hose if it's rated for propane it's safe to carry nat gas generally,but you need to have appropriate fittings to connect to nat gas gen,and only after you have installed low pressure gas fitting that needs to be attached to your nat gas source
ipe the one I have is for 1/2 inch nat gas pipe,after installing gas shuttoff valve:then another length of pipe (always dope threads)and you attach your low pressure regulater,which has connection for low pressure gas hose to generator.

Yes, you should be able to use a fitting like this in order to connect to your black pipe.
In fact, you HAVE to, because if you wanted to use iron pipe ALL the way to the connection, you would end up having to twist the co2 genny in the air in order to thread the final connection, or use a union joint below it.
Sorry if I wasnt more clear.
I actually have NOT installed mine yet; been on the to-do list for over a month :-(
I have no chiller for this application, I am using a VERY large water tank that is on my property as my recirc rez.
Hope it Helps

I would ABSOLUTELY put a shut off valve BEFORE the final 12 inches which is what this pipe would be used for.
I would physically mount the unit, so that it doesnt move and cause any stress to your new gas lines.
The HydroGEN NG unit comes with a regulator for itself.

yes after a shuttoff valve and if you are not going to be moving co2 generator then this will be ok I would Use the steel braided flexible hose much stronger,and safer than the thin walled typical gas dryer/range hose used.NO!unsafe the flexible hose at the back of your appliance is not meant to carry gas before a shuttoff valve.they also are thin walled have tendacy to deteriate over time of if moved.
