This model replaces the AW3945-12. It is specifically designed to do no stucco damage during install. It is 5” deep not 12” deep so the heater is no longer built-in.
1. Reuse the current heater and request a bracket for mounting on the wall above
2. Add a new heater to the order (with bracket)
3. Add an air curtain to the order
