A combustion air vent system is essential to keep our furnace or heating system in proper functioning. It provides the fresh air needed by burning a furnace to burn its fuel.
Many combustion air types followed directly into the furnace for proper burning of the stove fuel.
The average cost of installing a combustion air vent system ranges between 450 dollars to 1500 dollars if you install a combustion air vent system by some professional.
But you can save up to 200 dollars if you perform that installation yourself. It is undoubtedly a difficult and skilled job, but our provided guidelines will help you install a combustion air vent system yourself.
Why I need a Combustion Air vent system?
It is not necessary for each furnace or heat system should install a combustion air vent system. Modern technology-equipped furnaces or heaters need a proper combustion air vent system for the right and efficient functioning.
A proper combustion vent system keeps us protective from dangerous gases which may create due to burning of fuels, no matter how modern heating or furnace systems, all still need burning of fuel and exhale hazardous gases.
Only with a proper combustion air vent system can we keep ourselves protective from these gases. The second reason is that more oxygen supplied for burning fuel works properly with a combustion air vent system in the presence of fresh air.
What are the types of Combustion Air vent systems?
It depends on your furnace; it may install inside the room or outside of your room. In the hot areas, mostly furnace or heaters are installed outside, and there is no hard requirement for the combustion air vent system.
But in cold areas or you need a furnace or heater inside the room, you need a proper combustion air vent system for a furnace’s appropriate functioning and safety.
There are two major types of combustion air vent systems, as explained below.
First Type of Combustion Air vents System
The first type is the atmospheric combustion air vent system; in that system, exhaust from the furnace rises out of the combustion chamber, and then it travels to the roof and opens in the outside environment.
It looks like a traditional chimney style; the benefit of this combustion system is that you do not need motorized fans for its functioning because gases easily exhale through the pipe into the outside environment.
But you will need a good quality pipe, which makes it possible for the furnace to exhale the gases in the open air without any interruption.
Second Type of Combustion Air vents System
The second type is the power venting or direct venting system, which is most flexible and uses a combustion air vent system. In that system, you do not need a direct line to the roof.
In such type of systems, gases expel through a pipe which runs outside on your exterior wall.
How to install the Combustion Air vent system?
Here are some tips that will help you install a combustion air vent system yourself professionally.
Start with taking measurements such as the height of the existing air vent opening from the floor. It would help if you took the size of the bottom and top of the air vent.
Measure the air vent system’s distance from each wall to know which wall is more close and easy to access. It will be helpful for you if you write the measurements on a piece of paper.
Mark Points, according to Measurements:
Now take a marker and a large ruler and mark the points per measurement for the ventilation system’s easy installation.
Make sure you are properly marking the points according to measurements. Keep in mind the bottom and top points of your combustion system.
After marking the wall points, take a knife and score the lines on the wall now; using a keyhole saw, cut the opening on the wall through the lines.
Make placement of sheet and covering sheet.
In the next step, you will need to place a sheet on the wall in the opening air vent; it is better to screw or nail the sheet to keep it in place.
Take the air vent cover in the opening position and mark two holes for screwing on the wall using a pencil.
Using a drill machine, make holes on both points and make sure proper holes open from both sides of the walls.
Placement of anchor
Now adjust the anchor’s placement, screw them on the air vent cover, make the right position of air vent cover, insert the screws into the anchors, and make them tight for firm fixation and firmly place the vent against the wall.
Check the system, ensure that everything is properly installed and also works properly.
A combustion air vent system is essential to keep our environment safe and the proper functioning of our heaters’ furnaces. It is a costly job if you hire professionals, but you can save sufficient money by installing a combustion air vent system by yourself.
