The STR series are approved for direct vent applications.
The system must not be operated in a negative air condition, unless combustion
air is brought in from outside directly to the burner. If a severe negative pressure is ex-
perienced or anticipated, order heater requesting custom Air Switch c/w Air Hose from
Schwank.
* Ensure you specify the correct heater model number when ordering.
