Vent-free Propane/LP Heater

Vanguard Mini-Hearth Vent-Free Propane/LP 15,000 to 30,000 BTU/HR heater with thermostat, 2-function blower and push-button pilot lighting. It has a slide-open panel to access the fan and thermostat controls from the top. We have the manual. It has a minor blemish on the top that will probably polish-out and some minor scratches (see photo). It is in otherwise good condition and works well. We decided to replace it with a wood stove.
