When mounting a BJ thermostat to a flange, what must you be careful of?

When mounting a BJ thermostat to a flange, it is crucial to ensure that the quad ring is properly positioned in the flange. The quad ring serves as a seal that prevents leaks between the thermostat and the flange. An improper positioning can lead to an incomplete seal, which may result in gas leakage, reduced performance, and potential safety hazards.

A well-positioned quad ring ensures a secure fit, maintaining the integrity of the system and allowing for effective temperature regulation. This attention to detail is essential because any gaps or misalignment in this sealing mechanism can compromise the overall function of the thermostat and the equipment it regulates. It is important to take care with this step to avoid future issues related to efficiency and safety.
