Pellet grill startup guide
How to start a Pit Boss pellet grill the right way
Published July 23, 2026

Bob fired up his Pit Boss for the first time, skipped the startup steps, and ended up with a grill full of unburned pellets and a temperature that swung wildly for an hour. The fix is a specific two-step sequence that takes about 10 minutes and costs nothing. Get the startup right once, and every cook after it runs smoother.

Quick answer
Start the Pit Boss with the lid open on the Smoke setting (180-210°F) for 10 minutes to clear excess fuel from the firepot. Then close the lid and dial to your target temperature, commonly 225°F for low-and-slow work. Expect a normal swing of +/- 25°F around your set point. That is not a malfunction. Budget 2 lbs of pellets per hour for smoking and 4 lbs per hour for high-heat grilling so you do not run dry mid-cook.
The lid-open startup is not optional
Every Pit Boss startup begins the same way: lid open, dial on Smoke, wait 10 minutes. The Smoke setting holds the grill at 180-210°F and runs the auger in short bursts to feed pellets into the firepot. Starting with the lid open lets any excess fuel burn off cleanly instead of smoldering and building up inside the cook chamber.
Skipping this step is the single most common reason a Pit Boss produces thick white smoke, temperature spikes, or a firepot overflow on the first cook. Flip calls it the "clear the chamber" rule. Bob learned it the hard way after his first brisket tasted like an ashtray.
- 1Open the lid completely.
- 2Turn the dial to Smoke.
- 3Wait 10 minutes. Do not close the lid early.
- 4Close the lid and set your target temperature.
- 5Give the grill another 10-15 minutes to stabilize before adding food.
Temperature swings are normal on a pellet grill
The Pit Boss controls heat by cycling the auger on and off at timed intervals. Pellets drop into the firepot, catch, burn down, and the cycle repeats. This design means the temperature does not hold a perfectly flat line. A swing of +/- 25°F around your set point is normal and expected.
If you set the grill to 225°F, you will see readings from about 200°F to 250°F during normal operation. That range is fine for smoking. Do not chase the number by lifting the lid or adjusting the dial every few minutes. Lifting the lid on any setting other than Smoke disrupts the temperature control cycle and makes the swings worse.

The P setting only does one thing
The P setting, short for Pause, controls the length of the pause between auger cycles. It only works when the grill is on the Smoke setting. It does nothing on any other temperature setting. The default is P4, with P1 being the shortest pause (more pellets, more heat) and P6 being the longest pause (fewer pellets, less heat).
Use the P setting to fine-tune the Smoke setting if your grill runs outside the 180-210°F target range. If the temperature drops below 170-180°F, lower the P setting toward P1 to feed pellets faster. If it runs too hot, raise it toward P6. Wind and cold weather pull heat away faster, so you may need a lower P setting in winter than in summer.

Pellet math keeps you from running dry
Running out of pellets mid-cook is one of the easiest problems to avoid. The Pit Boss burns roughly 2 lbs of pellets per hour during low-and-slow smoking and about 4 lbs per hour during high-heat grilling. A full hopper on most mid-size Pit Boss models holds around 18-21 lbs, so you have plenty of runway for a long smoke if you start full.
Check the hopper before every cook. For anything over 6 hours, check it again at the halfway point. Pellets can bridge at the bottom of the hopper and stop feeding even when the hopper looks partially full. Give the hopper a gentle shake every few hours to keep pellets moving toward the auger. You can find gear that makes long cooks easier on the Grillibe gear page.
What to do after the cook
When you are done cooking, turn the dial to the highest temperature setting for about 5-10 minutes to burn off grease and residue in the firepot. Then turn the dial to Smoke for 2-3 minutes, then to Off. This sequence lets the auger clear excess pellets and reduces the chance of a firepot overflow on your next startup.
Empty the grease bucket after every 2-3 cooks. A full bucket is a grease fire waiting to happen. Store your pellets in an airtight container away from moisture. Wet pellets crumble, jam the auger, and cause temperature problems that look like grill malfunctions but are actually just bad fuel. Once your startup and shutdown routines are locked in, you are ready to put the grill to work. A good first project is smoked chicken thighs, which are forgiving and fast.

FAQ
Why does my Pit Boss temperature spike at startup?
A temperature spike at startup almost always means the firepot had leftover pellets from the last cook or the lid was closed during the initial burn-off. Always start with the lid open on the Smoke setting for 10 minutes. This clears excess fuel before you close up and set your cook temperature.
What does the P setting do on a Pit Boss?
The P setting controls the pause time between auger cycles, which adjusts how many pellets feed into the firepot. It only works on the Smoke setting. The default is P4. Lower numbers like P1 feed more pellets and run hotter. Higher numbers like P6 feed fewer pellets and run cooler. Use it to keep the Smoke setting in its 180-210°F target range.
How many pellets does a Pit Boss use per hour?
Plan on about 2 lbs of pellets per hour for low-and-slow smoking and about 4 lbs per hour for high-heat grilling. Always start a long cook with a full hopper and check it again at the halfway point to avoid running dry.
Is a 25-degree temperature swing on a Pit Boss normal?
Yes. The Pit Boss cycles the auger on and off to control temperature, which creates a natural swing of +/- 25°F around your set point. If you set 225°F, readings between 200°F and 250°F are normal. Do not adjust the dial or lift the lid to chase the number, as that makes the swings worse.
Can I close the lid right away when starting my Pit Boss?
No. Start with the lid open on the Smoke setting for the first 10 minutes. Closing the lid too early traps unburned fuel and can cause a temperature spike, excess smoke, or a firepot overflow. After 10 minutes, close the lid and set your target temperature.
