Locate the EC-Gold Dual on a vertical surface away from drafts, open doors or windows,
condensation or dripping moisture.
The vertical placement (above the floor) depends on the gas being monitored. For CO, the unit
should be located within the breathing zone: about 4 - 5 feet above the finished floor*. For other
gases, refer to an Arjay Engineering representative.
* Check local building codes (i.e. Ontario Building code requires mounting 2’11” to 3’11”).
