In this blog, we hope to answer some of the questions that often come up about our most popular product in our Zentro Brand of products.This product is our Zentro Smokeless Fire Pit. We hope this blog is beneficial to you as you look to find which fire pit will work best for you. Below are some frequently asked questions about our Zentro, and the answers to those questions, and some benefits that the Zentro Smokeless Fire Pit provides.

Question: Is the Zentro really smokeless?

Answer: Yes, the Zentro Smokeless Fire Pit is really smokeless. Once the fire has reached full size and the walls of the fire pit have been heated up, the fire pit reduces an estimated 80%-90% of the smoke that the fire creates (therefore "smoke-less"). There are several conditions that can hinder the smokeless technology from working properly. Some of these hindrances include; wood that is too wet, wood that is too green, or incorrect installation of the fire pit.

Zentro Benefit: The Zentro's smokeless technology keeps the dreaded smoke from chasing you and your friends around the fire pit and makes every seat around the fire pit become comfortable and inviting for you and your guests.

Question: Will the Zentro rust?

Answer: Yes, over time the Zentro smokeless fire pit will rust. The fire pit is made of steel and coated with a black, Hi-Temp Grill Paint. This grill paint is rated to withstand temperatures of 1,000 – 1,200 degrees Fahrenheit. However, this paint, along with all other grill paints in the market, can not withstand the direct contact of a fire. Because of this, the paint that comes in contact with the fire, mainly the paint that is inside the fire pit bowl, will begin to burn off within 1-2 uses of the fire pit. As the paint burns off and the raw steel of the fire pit is exposed to the outdoor weather, the spots where the paint has burned off will begin to rust. Again, this is something that mainly happens inside the fire bowl of the fire pit.

Zentro Benefits: There are a few steps we have taken to make sure the Zentro is equipped to withstand years of use in the outdoors even with rust. First, we manufacture the Zentro smokeless fire pit with thicker gauge steel so that the rust does not have an effect on the fire pit’s strength and durability for multiple years. The fire pit is made of 116 pounds of steel and painted with a black, Hi-Temp Grill Paint. Second, a can of the black, Hi-Temp Grill Paint is included with every Zentro smokeless fire pit to allow you, the customer, to touch-up the spots of the fire pit that may begin to rust. However, there are some customers who would rather let the fire pit take on the natural rust (Patina) look.

Question: Will the Zentro Smokeless Fire Pit burn hotter than a normal fire pit?

Answer: Yes, the Zentro Smokeless Fire Pit burns approximately 25% hotter than a normal fire pit. The reason the fire pit burns hotter is due to the reburning of the smoke that the smokeless technology provides the fire pit. The fire pit is also more enclosed than most fire pits which allows the fire pit to retain heat for a longer period of time.

Zentro Benefit: The extra heat that the Zentro generates will provide you and your friends greater warmth when sitting around the fire on a cool evening. It also provides higher cooking temperatures which are great for cooking and searing steaks, and other foods over the fire.

Question: What size is the Zentro and what size fire ring does it fit into?

Answer: The Zentro has a 24” inside diameter, and fits into a fire ring with an inside diameter of 30” – 32 ½”. If a larger fire ring than 32 ½” is being used, a Zentro Retro-Fit Ring must be used to fill the extra space of the fire ring. The Zentro 41" Retro-Fit Ring allows the Zentro to fit into a fire ring with an inside diameter of 33” – 38”. The Zentro 47" Retro-Fit Ring allows the it to fit into a fire ring with an inside diameter of 38 ½” – 44”.

Zentro Benefit: The size of the Zentro Smokeless Fire Pit fits multiple block manufacturer’s block fire pit kits. Here is a list of some of the kits that the Zentro fits into: Teco-Bloc's Valencia Fire Pit Kit, EP Henry's Fire Pit Kit, Newline Hardscapes Ashland Fire Pit Kit, Newline Hardscapes StoneLedge Fire Pit, Cambridge Olde English Wall Stones Fire Pit Kit, Cambridge Pyzique Wall Stones Fire Pit Kit, Ideal Scapestone Fire Pit Kit, and others.

Question: Does the bottom of the Zentro fire pit have holes for water drainage?

Answer: Yes, the Zentro Smokeless Fire Pit does have multiple holes at the bottom to provide the fire pit with water drainage and better airflow. The holes are covered with slats that help to keep them from being clogged with ash.

Zentro Benefit: The holes on the bottom of the Zentro allow rainwater to drain out of the fire pit. The holes also provide additional airflow for the fire pit, which helps the Smokeless technology work more effectively.

Question: How often should the Zentro Smokeless Fire Pit be cleaned out?

Answer: We recommend that the Zentro Smokeless Fire Pit be cleaned out every 4-6 uses, as long as the fire burns completely down to a fine, grey ash each time. This number of uses can also be determined by the amount of wood that was burned during each use. Using a shovel and ash bucket, the fire pit can easily be cleaned out in 5-10 minutes.

Zentro Benefit: Keeping the Zentro Smokeless Fire Pit free from ash will allow the fire pit to burn more efficiently.
