Operating Instructions
The Dimplex LC2507W31 baseboard heater operates by convection, drawing in cool air from the bottom and releasing warm air from the top. This model typically requires an external thermostat for temperature control (not included).
1. Initial Power-Up

- The heater may emit a slight odor during its first few hours of operation. This is normal and will dissipate quickly.
2. Temperature Control
- If an external thermostat is installed, set the desired room temperature using the thermostat controls.
- The heater will cycle on and off to maintain the set temperature.
3. General Operation Tips
- Do not block the air intake or outlet grilles. This can reduce heating efficiency and pose a fire hazard.
