Condensing tankless water heater venting. Water is an essential part of our lives. It is not just for drinking but cleaning and other stuff is also done by it.
In the middle of winter, bathing with cold water is like asking to be frozen to death. So to overcome this, water heaters were developed.
The latest of them is the tankless ones. But there comes the problem of venting in them. Actually, the tankless heaters that are condensing do not require any type of venting.
But we can do so if we want to. It can be done from the walls or even the roof as you want it to be. Let us see what we are able to do with it.

But it can be great in longing the life of your device as well as giving you better results than before. But there are special rules set by the government for this.
The rules can be different in countries, but the most general ones are the same. Like the heater should be placed really close to the venting.
The distance should be as least as possible. The vent pipe should not be welded together.
Let us discuss more of the rules and steps of installation within them.
Rules set by GOVT

- The vent collar should not be cut.
- For inspection and maintenance, the top of the vent must be easily removable from the heater.
- The vent must not be connected to any other device.
- The pipe must be of the proper size. It shouldn’t be too long.
- A cap or cover should be placed on top of it such that no water enters it in case of rain.
Required things

- Brackets
Installation Steps
The steps should be followed precisely for safety purposes.
Water heater
The first step is installing the water heater. Find a proper place or select where you want the heater to be and then install it at that place.
Selecting terminating method
After installing the heater itself, you need to find or think of the method you want in termination. Think of the pipes should be separated in concrete or not.
Think if they should be placed in a vertical position or in the sidewall. Select your method carefully.
Location
The location for installation should be determined carefully. The location of roof termination should also be selected clearly.
Assembly installation
After the locations have been set, you need to install the assembly now.
Install it carefully so that there are no problems after you start the machine. You should check it twice just to be sure.
Piping
If you are finished with the installation of the assembly and others, you can start installing the pipes.
First, you should connect and install the air piping from the heater to the termination, and then the vents should be installed in the same way.
Sloping
Proper sloping should be done according to the rules of the area. The horizontal exhaust pipe should be sloped downwards, meaning it should be placed in the direction of the water heater.
The direction of the slope of the combustion pipe should be away from the unit, not towards it.
Pipe support
After installing the above parts or the components of functionality, you should move on to the pipe supports.
They are very important as they support your pipes and help them stay put in the location.
They should be placed or installed with pipes at a distance of every four feet.
This will make your the pipes and components are not loose, and they have proper support.
Finishing touch
After you have done that, install the extra components if you want. They are not necessary, but they can be used as the finishing touch.
After the device has been properly set and all the components have been properly installed, you should test the system to see if all parts are in the proper position and their installation is proper.
Conclusion
Condensing tankless water heater venting. The installation might be a bit complex for you if you have o knowledge about this kind of stuff. But if you read the steps carefully, then you will also be able to do so.
But do not forget to follow the local rules as they are really important for safety, and not following them can be considered illegal.
So always follow the rules according to your the rules that I wrote above are for America. They might not be applicable everywhere.
