Planning
Before that, when going to install, make a plan; for that, you need to read the manufacturer’s instructions for the correct positioning of the unit. You can also decide by reading that do you need some connector or particular venting material. You will also need to verify that the appliance is a category I or category B appliance.
Placement

Draw Sketch
It is helpful for you to place the venting system at the proper place is to sketch the installation before placing it. Also, adjust the lengths and available makeup odd lengths. Try to minimize the turns and lateral runs for the better and perfect performance of vent B systems. It is better to turn the pipe in 45 degrees instead of 90 degrees.
Make Clearance to Combustibles
Try to keep an air space to combustibles; 1-inch clearance to combustible materials is necessary to maintain and recommended, no matter whatever is the diameter of your pipe.
Ensure Air combustion
When installing the B vent then referring to your installed appliances and local building codes, it is necessary to ensure proper air combustion for each installed appliance. It is also necessary to check the volume of the air combustion. It should be according to recommended instructions according to local codes.
Make a Slope
If you are going to install the venting system in horizontal positioned components, then positioned them on an upward slope and away from the appliance but not less than ¼ inch of rise per foot of run. When you install lateral position in attics or walls or between unconditioned areas, please consult with local building codes and the limitations in your area.
Termination of Area
When you are going to install the B vent system in the termination area, try to determine the height of termination above the roof and the roof pitch adjacent to adjacent walls or any obstructions.
When installing the vent pipe with 3 inches to 12 inches in diameter, it must then terminate at least 2 feet higher than the adjacent obstructions and walls.
No matter the purpose of your B vent system for water heaters, furnace connectors, or any other appliance, try to adjust the slop below 90 degrees. Also, keep the range of pipe diameter between 8 to 14 inches.

If you do this, try to enclose the outside portion of the system in the chase. But before that, consult with the local authority for constructions.

You can only terminate the B vent Pipe in a horizontal position. But the use of a B vent pipe is not compatible with the recommended appliances to place horizontally.
Important Note:
Never Forget to consider and read the local codes about installing the B vent system; if necessary, then only follow the approved ways to install the B vent system according to rules.
