Industry Leading Warranty


Not all warranties are created equal, so we encourage you to become an informed customer and read the fine print! Some outdoor stove manufacturers who advertise a Lifetime Warranty actually offer little to no warranty, but don't disclose the details. Protect yourself and your investment by always asking to see the full warranty. Our twenty year warranty provides you with the highest quality, longest lasting warranty on the market. 

One Year Warranty

  • On electrical components - Parts only - Aqua stats, thermostats, fans and pumps are guaranteed by the manufacturer for a period of one (1) year from the date of purchase. Parts will be replaced on an even exchange, excluding shipping charges and labor. 
  • The loading door, ash pan, door gaskets and ceramic moldings are warranted for a period of one (1) year from date of purchase.
  • If there is a leak in the fire box or water jacket on your Crown Royal Stove during the first (1) year - Greentech Manufacturing Inc. will replace the unit at no cost to the original owner. The owner is liable for the un-installation of the old unit and the installation of the replacement unit.
