There have been several past posts on our Facebook group page about a concept called bypass dehumidification. I think technicians could benefit from learning more about this topic.  Bypass dehumidification or airflow is an interesting method for utilizing mixed air temperatures to maximize a system’s dehumidification capabilities.

Proving flame is an important part of the gas firing sequence. Without proof of flame, you risk dumping unspent gas into the heat exchanger, resulting in an explosion. There are many ways to “prove flame,” but we are focusing on the flame sensing rod (flame rectification) method here. Here are the facts: Flame sensing rods, […]
