Boulevard 36 Direct-Vent fireplaces (29,000 BTUs Nat and 28,000 BTUs Propane) are designed with a fully-recessed burner to fill your fireplace with lively flames. Every Boulevard includes an electronic intermittent ignition system that eliminates the standing pilot to help you save energy and money. The system includes battery back-up located in a wall box for manual or remote operation.  The remote allows you to switch to a standing pilot mode, which is recommended in cold climate conditions.
