Checking Power Supply
Wall Outlet Before plugging into any outlet, be sure to test it.
Proper polarity and correct voltage are of the utmost
importance.
To check polarity; There are plug in testers available that
simply plug in and reveal a series of lights to tell you if the
polarity is correct. You can also use a volt meter to test it.
Place one lead in each of the vertical slots of the outlet, you should
have a reading of 112 to 122 Volts. Now place one lead in the
smaller vertical slot and one lead in the rounded Ground slot.
Here you should get the same reading as
you did between the two vertical slots.
For the third test, place one lead in the
large vertical slot and the other lead in the
ground slot; you should get a reading of
0 to 10 Volts only.
Some people seem to think that an outlet is fine because their lamp
and radio work fine plugged into it.That is not true. These items have
a very basic Power requirement compared to the microprocessors
on the Harman Circuit boards.
Surge Protection Is Recommended For All Pellet Units
And required when using a Battery Back-up.

Draft Testing
All Harman pellet units have a test port on them for checking the draft.
There is a draft meter kit available from Harman Stove Company, which also
includes a digital multi-meter. This draft meter includes a bolt-type fitting
to attach the meter to the stove.
Taking a draft reading before installing the venting will give you a reference point
to shoot for after the stove is vented. Lower readings after installation indicate
possible restrictions in the venting.
