What does 12" from a vertical surface mean?
The instructions state that this heater must be mounted more than 12" from a vertical surface. What, exactly, does that mean? I was hoping to install this near my shower door. Does it have to be one foot away from the shower?
Thank you for your question on the model 9815WH wall heater. What is meant in the installation instructions by 12” from a vertical surface is something like an adjacent wall. If you get too close to a vertical surface, adjacent wall, shower door etc. you can get heat buildup in that corner which affects the thermostat on the heater. Also, you should NEVER mount a switch or electrical device within arms reach of the tub due to electrical shock.
