NOTE: Improper location of a turbulator can cause malfunction of the heater,
property damage, and will void the heater warranty.
Tube Kits are supplied with 4 ft & 10 ft turbulator(s) factory installed into the
tube(s). Tubes with turbulators are clearly labeled for easy identification. Two
models require that a 2 ft turbulator be installed in the field (see * below).
