I Have a new gas coal effect stove rated at 25,000 max. BTU. Its a Vista model by ESSE from England. I have an oven thermometer on top of stove it reads 300 deg. F. at Max. Does this sound about right for a gas b vent stove. Compared to a gas wood stove? Its a cast iron stove with open grate on top convection and radiant with ceramic window.
