Is the chain tensioner included in the box

It prevents the massive current draw of multiple heat strips from hitting the line all at once and allows the heat exchanger to reach temperature before the blower starts

Using the included high-temperature silicone gasket prevents flammable vapor infiltration and maintains the integrity of the FVIR system

reducing operational costs
