Answer / Procedure

The hopper temperature sensor monitors the temperature of the hopper and is part of the stove's safety system.

If the sensor requires replacement, follow the steps below.

---

Before You Begin

1. Turn the stove OFF.
2. Allow the stove to cool completely.
3. Disconnect power from the stove.

---

Step 1 – Remove the Existing Sensor

Locate the hopper temperature sensor mounted in the hopper wall.

Carefully pull the sensor and attached wire through the mounting hole.

---

Step 2 – Apply High-Temperature RTV Silicone

Apply a thin, even bead of high-temperature RTV silicone around the body of the replacement sensor.

The silicone helps create an airtight seal between the sensor and the hopper wall.

---

Step 3 – Install the New Sensor

Insert the sensor into the mounting hole in the hopper wall.

Press the sensor firmly into place until it is fully seated.

---

Step 4 – Allow the Silicone to Cure

Allow the RTV silicone to cure completely according to the manufacturer's instructions before operating the stove.

---

Important Notes

• Use only high-temperature RTV silicone suitable for pellet stove applications.
• Ensure the sensor is fully seated to maintain an airtight seal.
• Avoid disturbing the sensor until the silicone has completely cured.
• An improperly sealed sensor may allow air leakage that can affect stove performance.

Escalate To Support If

Contact support if:

• The sensor will not seat properly in the hopper wall.
• The sensor wiring is damaged.
• The stove continues to display overheat or hopper temperature faults after replacement.
• Additional wiring or control board issues are suspected.
