3. TURBULATOR LENGTHS & LOCATION IN SYSTEM
NOTE: Improper location of a turbulator can cause malfunction of the heater, property
damage, and will void the heater warranty.
Tubes with turbulators inside are clearly labeled for easy identification.
ALL turbulators are located within the BASE LENGTH (shortest length) of the tube sys-
tem. One or two tubes added to system base length are regular empty tubes with no turbulators.
Each turbulator is 36 inches in length by 2.25" wide (see Table below).
Turbulators link together with tabs, and individual sections can be removed by straightening tabs (see
below). A Base Tube Kit may need turbulator removal depending on input rate (see below and illustra-
tion next page).
The orientation of the turbulator(s) [up - down; sideways] in the tube does not matter.

the tube. Rotate the tube to have ac-
cess to the locking tab
