G315 Series Oil Boiler

The boiler sections are assembled with beveled, surface profiled push nipples for long, trouble-free watertight operation. Boiler flue ways are manufactured to be gas tight with tongue and groove section design and elastic, high temperature resistant sealing rope. This seal is fully pressed into the groove during assembly to allow positive pressure operation. A permanent dry door gasket ensures repeated positive sealing of the full swing burner door. Because flue gases cannot escape through the seams between boiler sections, the boilers are able to retain heat more efficiently.
