Napoleon High Country NZ6000 Installation And Operating Instructions Manual page 25

As soon as the door is closed, you will observe a change
in the flame pattern. The flames will get smaller and lazier
because less oxygen is getting into the combustion cham-
ber. The flames, however, are more efficient. The flames
will remain lazy but become larger again as soon as the
firebricks have been heated thoroughly and the chimney
becomes heated and provides a good draft.
At this point, the roaring fire that you see when the door is
opened is wastefully drawing heated room air up the
chimney -- certainly not desirable.
So always operate with the door fully closed once the me-
dium sized logs have caught fire.
You can now add larger pieces of wood and operate the
fireplace normally. Once the fireplace is entirely hot, it will
burn very efficiently with little smoke from the chimney. There
will be a bed of hot coals in the firebox so you can safely fill
the firebox with wood to the top of the andirons.
Can't get the fireplace operating? Use more kindling and
paper. Assuming the chimney and vent are sized correctly
and there is sufficient combustion air, the lack of sufficiently
dry quantities of small kindling is the problem. Thumb size
is a good gauge for small kindling diameter.
Can't get heat out of the fireplace? One of two things may
have happened. The fireplace door may have been closed
prematurely and the fireplace itself has not reached opti-
mum temperature. Re-open the door and/or draft control to
re-establish a brisk fire. The other problem may have been
wet wood. The typical symptom is sizzling wood and mois-
ture being driven from the wood.
FUEL LOADING AND BURN CYCLE
The bricks will be nearly all white and the glass mostly
clear. The whiteness of the bricks and the cleanness of the
glass are good indicators of your operating efficiency.
Not enough heat is produced when only one or two pieces
of wood are burned.
A minimum of three pieces are needed to encase a bed of
coals that sustains the fire. Loosely stacked wood burns
quicker than a tightly packed load.
Wood burns in cycles rather than giving a steady output of
heat. It is best to plan these cycles around your household
routine so that only enough coals are left to start the next
load. In the evening, load your fireplace, at least, a half-
hour before bed to ensure the fire is hot enough to close
the draft control for an overnight burn.
Burn only dry seasoned wood. It produces more heat and
less soot or creosote. Do not burn ocean beach wood. Its
salt content can produce a metal eating acid.
