I bet you’re getting lots of calls for gas log service and installation right now! We’ve been getting quite a few people asking about the differences between Millivolt & IPI burners, so this month That’s what we’re going to review.
Helping your customer choose the right ignition system for their log set can significantly affect convenience, efficiency, and long-term operation. The two most common systems we sell are Millivolt (Standing Pilot) and IPI (Intermittent Pilot Ignition). While both are reliable, they function very differently and each have their own benefits. I don’t have room to cover Variable flame burners in this newsletter today, but that is another commonly used standing pilot system.
Let’s start with Millivolt systems. These burners use a continuously burning pilot flame. This small flame generates a tiny electrical current (millivolts) that powers the gas valve and allows the burner to come on.
