Theseunitsarepre-testedatthefactorywithexactly120VAC,
60Hz.Theyarecheckedandadjustedforreboxtightness,
gasket leakage, motor operation and igniter operation. The
P42i-TCisthenfactorysetatamid-pointadjustmentandin
most cases will not need any adjustments.
Checkandrecordthereboxdraftbeforeinstallingventing
and after venting is installed (before starting re).
There is a silicone draft meter port located behind the left
handdooratthepowersupplyplug.Installthemagnahelic
meter (capable of at least .5” of water column) Figure 5.19.
Considerationsforsuccessfuldraftinclude:
• Negativepressureintherebox
• Locationofapplianceandchimney
To measure the draft or negative pressure on your appliance
use a magnahelic or a digital pressure gauge capable of
reading0-1inchesofwatercolumn(W.C.).
The appliance should be running on high for at least 15
minutes for the test.
With the stove running on high you should have a negative
pressure equal to or greater than the number given in the
chartbelow.Ifyouhavealowerreadingthanyoundonthe
chart, your appliance does not have adequate draft to burn
the fuel properly.
Press the icon a second time, the combustion fan will go
to“Maximum”(assetintheAuthorized Dealer Only area
underthecombustionfanicon)
The“Maximum”isfactorysetat2900RPM.AllowtheRPM
tostabilizeandrecordthereboxdraftMaximum.

Leavingthetestscreenwillendanytestsinprogressand
goes back to whatever mode of operation it was set to on
the home screen.
Iftheunitisnotadjustedproperly,itdoesnotcauseasafety
concern.Iftheunitisadjustedtoohigh,onlye󰀩ciencyislost.
Iftheunitisadjustedtoolow,thelowdraftpressureswitch
will not allow the feed motor or the igniter to operate.

Silicone Draft Meter Port
The Draft Test Port can be accessed from inside the left hand
side door just below the power supply plug.
Plugunitintoa120VAC,60Hzoutlet.
Gotothe“HomeScreen”,thepowericonshouldbegray.
Pressmenu,ontherstmenupress“test”.
The test screen has 4 component test modes. The second
icon is for the combustion fan test.
Onepressoftheiconturnsthecombustionfantofullline
voltage. (Note: During this test , the combustion fan will
not achieve its top RPM of 3200 due to the density of the
ambient air.)AllRPMdisplayscouldvary+/-50fromthat
ofthesetRPM’s.Allowseveralminutesforthefanmotorto
warm up.
Do not allow pellets or sawdust to build up on the hopper
lip. Figure 5.18.
Inspect the hopper lid gasket for damage. A good hopper
lid seal is very important for proper operation.
