Z-Vent: What is it?

  • Z-VENT vent pipe is made of AL294c stainless steel which is durable enough to use in hi-efficiency boilers and tankless water heaters. The acidic condensation produced in todays equipment will not corode Z-Vent pipe.
  • Gasketed connections,no need for sealant when joining pipe
  • The only brand that is cutable
  • UL1738 listed for Category I, II,III and IV heating equipment.
  • Used for venting appliances with positive pressure of 8" of water column or less.Tankless water heaters are below this range and can use the Z-Vent for venting.
  • Z-Vent® recommends that an experienced professional who works with venting systems perform the installation.
  • Z-Vent® should not be combined with any other manufacturers brand of vent pipe because the connections are different.
  • Maximum flue temperature for the Z-Vent is 480 degrees F.
  • Limited 15 year warranty
What you see is a byproduct of the way that the Z-Vent pipe is cut as it comes off our tube mill machine at the factory. You will see a brownish film (slag) that usually goes down the inside of the vent length for some distance. This film can be wiped off with your fingers and appears to look like rusting or sooting. You will also notice some minor pitting as you get closer to the end as this is the point of the highest heat concentration during the cutting process. The seals may also pick up some of this “slag” giving them the appearance they are used. You will only see this on the pipe and not any of the fittings because the pipe is fed on a continuous coil of stainless steel where as the fittings use single sheets of stainless steel.
Yes, Z-Vent is the only Brand of AL294c pipe that is cutable. You can use a hacksaw with a carbon steel blade to cut thru the non-gasketed end of the pipe.

* Do not a vice to secure the pipe, another person holding as you cut is the safest way.

*Always wear protective gloves and glasses when cutting the pipe.

* A metal file may be required to file any burs before inserting into the gasketed end.
NO, insulation can not be used to insulate the pipe.( UL 1738 code) If you are in a cold climate area where a greater amount of condensation will be produced,use a Z-Vent condensate drain instead of insulation. The condensate drains are available in 3 types:Vertical in-line, horizontal or in a Vertical Condensate Tee.
NO, sealant,screws or tape should not be used to secure any connections on Z-vent pipe. The hi-temp gasketed end of the pipe is enough for a tight connection. Using screws will cause a leak of deadly carbon monoxide gas. Any type of tape is not suggested,the pipe has the UL listing without using any additional fastners.
Any other type of vent pipe will not have an air tight gasketed connection and will corode in a short period of time. This will cause a deadly carbon monoxide leak and could cause a fire. B-Vent, even though a double wall, has an alunimum inner pipe and galvanized outer shell that will not hold up to the corrossive condensation produced by Tankless water heaters or Hi-efficiency condensing boilers. Your installation manual for your appliance will list the correct UL listing and/or a short description of the required venting.

Z-Vent Installation questions

Several of the Z-Vent items available have Video and audio available in order to assist the professional in the "how-to" of installation
Condensate Drain
Straight Pipe
Adjustable Pipe
Elbows
Terminations
Firestop
Roof termination
Wall Thimble
Appliance adapters
Gas Flex Hose for Tankless Installation
No,the Tankless water heater venting has to have its own separate vent pipe. Common venting with another appliance is against code and you tankless will not perform under that condition.
No, your exhaust pipe has to be vented all the way to the outside of the house or building. Venting to the chimney does not allow the chimney to draft the flue gas, resulting in carbon monoxide gas to stay in the chimney or settle back into the building. However, it is acceptable to vent thru and to the outside of a masonry chimney if no other appliance vents directly into the same flue without a liner. The chimney must meet all national and local building codes and be cleaned of all soot,debris and creosote before installing Z-Vent.
You installation manual should show the requirements as to the exit termination from doors and windows. If not,check your local code for their parameters. A PDF attachment on the bottom of this answer shows a Tankless water heater manufacturers termination requirements. This is only an example and your appliance may be different.If you're in an area where snow may be higher than 12 inches, your above grade termination should also be more than 12 inches.
Under the "Clearance Enclosed" section you will see an 8 inch clearance as the pipe passed thru a wall horizontally. This means that you need 8 inches clearance from all around the pipe, a 19 inch round hole if you are using 3 inch diameter pipe. The best way to minimize that 19 inch hole is to use a Z-Vent Wall Thimble,reducing the hole size to 7 inches when using 3"pipe. ( 8" hole using 4" pipe with a thimble, etc) The Wal Thimble acts like a sleeve that your pipe will pass thru.
If you have ordered from Cinnabar Equipment Co, an installation manual is included in each order. Also, an installation manual is available below under attachments in a .PDF format. As you are looking at the manual,please note the requirement of a condensate drain,clearance to combustibles during installation and requirements above the roof.

No, a chimney liner (no matter the material) is not acceptable for venting a Tankless water heater. A flexible chimney liner is not a UL approved method and again, is unsafe. Many people think that this could be an alternative to the correct rigid Z-Vent pipe, but it is not. Again, we are dealing with a deadly exhaust gas that needs the right material to do the job correctly.

The Termination Hood is the suggested termination because it has the exhaust blowing down and away from the building. It has a built-in Bird Screen like all the other termination options.
The hot flue gas will discolor stucco,melt vinyl and ignite wood siding if the gases are not directed away from the building.
No, the manufacturer does not recommend painting the pipe.
Most Tankless manufacturers only require our Z-Vent AL29-4C single wall stainless steel.However, it's always best to check with your local building inspector because your local code may require doube wall. The clearance to combustibles is the same with either using single or double wall Z-Vent brand of pipe. Please call Cinnabar Equipment for pricing on Z-Vent Double Wall.
No, even though Z-Vent is approved for Tankless water heaters and boilers,it can not be used with different manufacturers pipe.The connections are all different between manufacturers pipe so you would not have a safe venting system.
You can use galvanized clamps or galvanized hanger straps,stainless steel is not required.
The Z-vent intallation manual lists when and where clamps and supports should be used.
The Z-Vent pipe, like any brand of vent pipe, should be inspected at least once a year to ensure the connections are secure, sealed correctly and for any signs of rusting or deterioration. It is not recommended to paint, insulate or coat the pipe with any sealant or chemicals. Z-Vent does have a 15 year limited warranty on their product.Your Z-Vent installation manual states all the terms and conditions along with a warranty registration card.
