For single boiler applications, the firing rate controller is a L4006A. Set the L4006A firing rate controller for 175°F with a 5°F differential. On a call for heat, the burner will start in low fire and immediately go to high fire until reaching the 175°F setting of the L4006A firing rate controller.

turndown ratio is the maximum inlet fuel or firing rate divided by the minimum firing rate. An efficient natural gas burner requires only 2% to 3% excess oxygen, or 10% to 15% excess air in the flue gas, to burn fuel without forming excessive carbon monoxide.

Chat OnlineA fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
