What are Grill Vents?

There are myriad factors that contribute to a great grilling experience, of which temperature control is the most important and also one of the most challenging.

Your charcoal grill is essentially powered by two things—the coals sitting at the bottom of the cook box (fuel) and the oxygen flowing through it. Therefore, it’s important to control both types of fuel for successful grilling.

Grill vents, also called dampers are basically porta that are designed to feed oxygen into your grill.

These dampers aren’t to be mistaken for chimneys or exhausts that come with certain charcoal grill models but instead allow you to directly control the temperature inside the grill.

Before moving further, I should mention that grill vents only apply to charcoal grills, because gas grills feature built-in controls to help with temperature control and fuel supply.

The wider the vents are open, the more oxygen input into the grill, resulting in more heat in the cooking chamber.

When the vents are closed, the supply of oxygen is cut off, hence less heat flows into the chamber.

Weber Charcoal Grill Vent Settings

For various temperature ranges

High heat (450-550°F) – Fully open

Medium heat (350-450°F) – ½ open

Low heat (250-350°F) – ¼ open

Low and slow/smoke zone (225-275°F) – 1/4 – 1/8 open

Off – Fully closed

Where are the Vents Located on a Weber Charcoal Grill?

That depends on the model, but the vents on most weber charcoal grills are located at the bottom.

Some Weber charcoal grill models feature events at both the top and bottom, where the former is called exhaust dampers that are designed to take the smoke away, and the latter are known as intake dampers that provide airflow to the coals.

How to Use the Vents on a Weber Grill?

Many new and even avid grillers believe that the more charcoal used, the more heat generated inside the grill, but this isn’t the case.

As I mentioned earlier, most Weber grills come with two dampers—the vents on the bottom bowl, and a top lid damper.

Weber recommends opening the bottom dampers completely, and controlling the temperature via the top lid damper.

However, there are several other factors that can affect the temperature inside your charcoal grill such as the temperature outside, wind conditions, how clean your grill, and even the type of food you’re grilling.

How do the Vents on a Weber Grill Work?

The way Weber grill vents work boils down to three stages, so here’s the lowdown. The first stage applies to when you start your grill, and at this time you should open the grill vents completely to let oxygen in while keeping the lid shut.

Best Ammo (Round, Load, Cartridge) for a Successful Moose Hunt Hunting Calibers 04 Apr, 2020 Posted By: Foundry Outdoors Is the .270 Winchester a viable caliber/load/round/cartridge for moose hunting? The accurate answer is “it depends”. However, the goal of this article is simply to address the question of whether the .270 Winchester is within the ideal range of suitable calibers to harvest moose. As with anything, the devil is in the details. To answer the question completely, we would need to evaluate the downrange distance to the moose, the bullet type, the grain weight of the bullet, the physical condition of the firearm, the size of the moose in question, the shot placement, the local wind conditions, the expected accuracy of the shooter, the ethics of the ideal maximum number of shots – the list goes on. [Click Here to Shop .270 Winchester Ammo]What we can do is provide a framework to understand what average conditions might look like, and whether those are reasonably viable for a shot from the average shooter to harvest a moose in the fewest number of shots possible, i.e., ethically. Let’s dive right in. In the question of “Is the .270 Winchester within the ideal range of suitable calibers for moose hunting?” our answer is: Yes, the .270 Winchester is A GOOD CHOICE for moose hunting, under average conditions, from a mid-range distance, with a medium grain expanding bullet, and with correct shot placement.Let’s look at those assumptions a bit closer in the following table. Assumption Value Caliber .270 Winchester Animal Species Moose Muzzle Energy 3780 foot-pounds Animal Weight 1200 lbs Shot Distance 200 yardsWhat is the average muzzle energy for a .270 Winchester? In this case, we have assumed the average muzzle energy for a .270 Winchester round is approximately 3780 foot-pounds. What is the average weight of an adult male moose? Here we have leaned conservative by taking the average weight of a male individual of the species, since females generally weigh less and require less stopping power. In this case, the average weight of an adult male moose is approximately 1200 lbs. [Click Here to Shop .270 Winchester Ammo]What is the distance this species is typically hunted from? Distance, of course, plays an important role in the viability of a given caliber in moose hunting. The kinetic energy of the projectile drops dramatically the further downrange it travels primarily due to energy lost in the form of heat generated by friction against the air itself. This phenonemon is known as drag or air resistance. Thus, a caliber that is effective from 50 yards may not have enough stopping power from 200 yards. With that said, we have assumed the average hunting distance for moose to be approximately 200 yards. What about the other assumptions? We have three other primary assumptions being made here. First, the average bullet weight is encapsulated in the average muzzle energy for the .270 Winchester. The second important assumption is ‘slightly-suboptimal’ to ‘optimal’ shot placement. That is to say, we assume the moose being harvested is shot directly or nearly directly in the vitals (heart and/or lungs). The third assumption is that a projectile with appropriate terminal ballistics is being used, which for hunting usually means an expanding bullet.Various calibersA common thread you may encounter in online forums is anecdote after anecdote of large animals being brought down by small caliber bullets, or small animals surviving large caliber bullets. Of course those stories exist, and they are not disputed here. A 22LR cartridge can fell a bull elephant under the right conditions, and a newborn squirrel can survive a 50 BMG round under other specific conditions. Again, the goal of this article is simply to address the question of whether .270 Winchester is within the ideal range of suitable calibers to harvest moose - and to this question, the response again is yes, the .270 Winchester is A GOOD CHOICE for moose hunting. [Click Here to Shop .270 Winchester Ammo]This article does not serve as the final say, but simply as a starting point for beginner hunters, as well as a venue for further discussion.

After your grill is fired up, you will have to lower the temperature inside the chamber, but you also don’t want to cut the supply of oxygen to the charcoal.

You can do this by closing the vents either halfway or three-quarters of the way shut. Keeping the grill vents at this position will limit the flow of oxygen without starving the coals of oxygen completely.

Adding to this, this vent position will also help you achieve the right temperature needed for proper meat cooking—225°F. If the inside of your grill is getting too smoky, open up the vents a little more.

The last stage is when you want to fully extinguish the flames after you’re done grilling, which you can do by closing the vents completely.

To summarize how the airflow of a Weber grill works:

The vents at the bottom of your grill let in oxygen that’s present outside the grill.
The oxygen fuels the charcoal, which allows the coals to produce flames.
These flames are responsible for generating heat and smoke inside the grill.
The vents located at the top of the grill remove smoke and excess heat from the chamber of your charcoal grill, which consequently pumps more fresh air and oxygen into the grill.
Air cannot enter when the grill vents are closed, which means that the charcoal won’t burn, and the flames will die out.
If you want a higher temperature, open the vents to let more air in, and for a lower temperature close the vents partially.

Is Weber Hotter with Vents Open or Closed

If you close the vents to your Weber grill, you will deprive the charcoal of oxygen, therefore the fire will go out.

For a hotter grill and a higher heat temperature, the vents of your Weber grill should always be open.

Ideally, the vents of your Weber grill should only be closed completely when trying to put out the fire.

Weber Bottom Vent Open or Closed

The bottom vent of your Weber grill should always be open, you want to close them partially if you want to lower the temperature. If you’re experiencing flare-ups, close the top dampers partially.

Final Thoughts

Controlling the temperature inside your Weber charcoal grill is a matter of mastering how to use the grill vents.

Apart from opening and closing the when you start the grill, during the grilling session, and when trying to put out the fire, you should always keep the ash catcher clean to avoid hindering the airflow inside the grill.

If your Weber grill didn’t come with a grill thermometer, you can but a good model at an affordable price to keep tabs on the overall ambient temperature of the grill.
