Clogged Or Dirty Wick
One reason your kerosene heater flame is uneven or jogged is an accumulation of tar on the wick or some deposits. So, the solution is to burn dry the wick to resolve this problem. Allow the heater to burn dry its kerosene until it beats out. Follow the easy guide to burn dry your wick:

- Light the heater and let it burn for hours until it beats out.
- Make sure to blare the wick up to the utmost before the heater goes out. It supports better cleaning of your wick.

Incorrect Wick Placement
In some cases, even after a few wick replacements, there is still uneven flame. The possible reason is you have not pinned the wick correctly into its case or teeth. Ensure all parts you removed must be reattached in the same manner when replacement, including the wick.
Here's an easy guide on how to attach your wick properly:
- Open the new wick out of its packaging.

- Pin the wick into the teeth to attach. Make sure to put all the wick studs in their corresponding holes.
- Place the wick holder and close it tightly.
Your wick can be too old or dirty to repair by burn drying. That's why you continuously have an uneven flame. Good thing the wick is replaceable. So, change the old wick to the new one correctly.
Some heaters don't use wicks with pins which is a little confusing to attach. But all heaters have a gear shaft to raise and lower the wick with the turning knob. Here's the replacement guide to follow:

Handling Kerosene Heater
The kerosene heater guzzles oxygen as it burns. So, burning it in a small room or a not well-ventilated area, especially for a long time, can be dangerous.
It also emits hazardous gases that can be a health risk, especially to pregnant women, the elderly, and people with asthma.
Keep the kerosene heater away from other things, such as furniture, clothes, bedding, and other flammable materials.
Never mix kerosene and gasoline, even in a container. And gasoline is never a substitute for kerosene in case you run out of it. Use and follow siphon instructions to fill your fuel tank for up to 90% only.
Empty fuel from the tank when not in use when storing. Always use new fuel upon using the heater. Replace low-charged or faulty batteries.
