Questions about this item
How do I install the 3UG18 recessed heater in a 14-inch wide by 6-3/4-inch high wall opening?
Frame the opening to exactly 14 in. wide, 6-3/4 in. high and 4-1/2 in. deep, run a dedicated 208/240 V AC single-phase circuit with the correct ampacity for the chosen wattage, secure the housing with the supplied mounting brackets, then attach the steel grille.
What maintenance will the 3UG18 heater require after installation?
Periodically shut off power, remove the steel grille, and vacuum dust from the heating elements and interior surfaces to maintain the rated 158 °F temperature rise and prevent overheating.
At what point does the 3UG18 heater's thermal limit activate during continuous operation?
The built-in high-limit safety switch opens when the internal air temperature exceeds the designed 158 °F rise, cutting power to the elements until the unit cools.
