Horizontal Venting

This heater, when horizontally vented, must be installed with the

approved venting system. For horizontal venting installations these

tube heater are certified as a category III appliance.

This heater, when vertically vented, must be installed with the

approved venting system. For vertical vent installations, ER2STG

60-100 model and ER2STG 80-125 model are category I

appliances. The ER2STG 125-175 model is only Category I when

vented vertically with 6" (15.25cm) diameter vent pipe.
