Q: Why does it smell like paint or chemicals when I use my oven for the first time?

A: This is the result of residue from the manufacturing process burning off. Open all of the windows and doors in the room for proper ventilation and allow the oven to run with nothing inside for at least 45 minutes before the first use.

Q: Why does my oven flame stay on during the entire cooking cycle?

A: The oven on your Cosmo range uses a manual spark ignition with no auto reignition. The flame is designed to stay lit until the oven has been turned off. As your oven goes through the bake cycle, the size of the oven flame will increase and decrease to keep an average temperature within 20-30 degrees of the set temperature. 

Q: How can I tell when my oven has been preheated to the selected temperature?

A: Your Cosmo gas oven does not include an alert or indicator that the oven has reached the selected temperature. We recommend using a standard oven thermometer inside the oven to indicate when the oven has reached its set temperature. The oven will take 10-20 minutes to preheat depending on the set temperature. 

Q: Does my range come with a manufacturer’s warranty?

A: This range includes a 1-year manufacturer’s warranty with your new purchase from an authorized retailer. To view a list of authorized retailers, please visit

Q: Where can I find the warranty terms for this product?

A: The warranty terms are available online at Your unit is covered for both parts and labor for 1 year from the date of purchase. 

Q: All of my burners are clicking or sparking when I turn any of them on.

A: The burners on this unit will spark when you attempt to ignite any of them. This is normal operation and is an intentional side effect of the cooktop’s design.

Q: Why is hot air blowing out from the top of my oven door?

A: Your oven is equipped with a cooling fan to better regulate the internal temperature for more precise cooking. There are two vent locations: on top of the oven door, and behind the cooktop. This is intended by design and is normal operation.

Q: Why is my unit producing black soot when in use?

A: The most common cause of black soot being produced when using either the oven or the cooktop is an improper propane mixture or conversion. Check the propane gas source first, then review the LP conversion instructions

Q: Why does my oven’s fan continue to run after the oven has been turned off?

A: This is normal operation. The fan will remain on during the baking cycle as well as after the oven has been shut off until it has sufficiently cooled.
