We have a Napoleon Knightsbridge GVFS60. We were told by our propane man that we need the proper "orifices" for propane use. Do you sell conversion kits for this model? More importantly perhaps, is do you have a video of how we can make the conversion our selves?
While fuel conversion is possible by switching orifices on vented appliances, I'm afraid that is not the case for vent free appliances. Improper conversion of a vent free appliance can lead to dangerous off gassing into the room and as such, manufacturers only produce vent free appliances in one fuel type or the other.
