Frequently Asked Questions
Q: Which pan size should I use on the Thetford cookers?
Using incorrect pan sizes can cause heat to escape to surrounding areas. It can also slow down your cooking time. So, why settle for mediocre meals when you can quickly achieve perfect results with the right equipment? Check out the “Safe Cooking” chapter in the user manual to find the ideal pan size for your appliance.

Only operate the stove with the type of gas (propane or butane) and pressure, as indicated on the rating plate.
Q: Is it possible to make my burners more powerful?
We do not recommend modifying the appliance in anyway.
Q: What can I do when the flame goes off after igniting the oven?
If the burner hasn't caught within 15 seconds, let go of the knob and leave it for at least a minute before you try again. If it still won't light, get in touch with your dealer.
