Fan assisted, fitted with a piezoelectric ignition system for trouble-free starting and features a direct gas head assembly. Features safety solenoid preventing the unit from leaking gas without first being electrically started. Supplied with an approved propane gas regulator and hose. Tested and certified to CE/EN.
