The product you have selected is specifically designed for use with natural gas and will be shipped directly from the warehouse. However, if you intend to use it with liquid propane (LP) gas, you will need to purchase a Liquid Propane Kit (LP Kit) separately. This LP Kit is not included with the product and will need to be field installed by a licensed technician. We highly recommend the LPM-06 LP Kit for this product, as it is designed to work seamlessly with the item and ensure optimal performance. It is essential to note that failure to use the appropriate LP Kit may result in damage to the product, as well as pose a significant safety risk to you and your property.
