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” width (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.

1.Carefully pull out the turbulator sec-
tion to be removed from the swaged
end of the tube. The end of the turbula-
tor to be left inside the tube should not
extend beyond the swaged portion of
the tube. Rotate the tube to have ac-
cess to the locking tab
3. Lift up the end of the
turbulator that is left
inside the tube to disen-
gage the tab that was
bent in the vertical posi-
tion
2. Bend and push the
outer tab with pliers until
it is in the vertical posi-
tion
4. While still holding the
inner turbulator in its loca-
tion, pull the outer turbulator
to completely disengage
and discard
