GhostRider 0 Report post Posted August 11, 2013 I moved into a new apartment this month which has LPG gas cylinder installed.Am wanting to switch back to piped (Citygas); but the technicians said that the nozzles in the burner are not compatible and need to be replaced before turning on CItyGas.Any recommendations for contractors who provide this kind of service?
