Draft Inducer: Measuring and Adjusting the Flue Draft
The Draft Inducer has a manually operated Adjustable Draft Vane that when moved Up or Down con-
trols the amount of draft in the chimney. By setting this vane in the proper position the optimal draft set-
ting can be achieved.
(See “Figure 4”)
1) Allow the furnace fire to settle into stable state of operation (approx. 25 min.)
2)
Insert the Manometer into the hole that was previously drilled in the stove pipe and observe the meas-
urement of flue draft.
(See “Figure 5”) The WinterGreen Furnace requires a draft of .05” to .07” Wa-
ter Column (WC) measured with a Manometer.
3)
If the measurement is below
05” WC
then there is not enough draft and it must be increased to avoid
air starvation of the furnace. Move the Adjustable Draft Vane on the Draft Inducer
(See Fig.4)
“UP” and
increase the draft until a reading is achieved between
.05” - .07” WC.
4)
If the reading is above
.07 WC
then there is too much draft and it must be reduced to prevent over
firing of the furnace. Move the Adjustable Draft Vane on the Draft Inducer
(See Fig.4)
“DOWN” and de-
crease the draft until a reading is achieved between
.05”- .07” WC.
5)
When the desired WC reading is obtained the hole in the chimney should be plugged with furnace
putty.

) Observe the barometric damper and see if it is operating smoothly. There should be some movement
of the gate but it should not be operating erratically. If the gate movement is erratic, make an adjustment
to the draft weight by turning the adjuster “in” or “out” until the gate stabilizes.
(See “Figure 1”)
