D. Combustible/Non-combustible Materials
• Combustible Material - Material made of or surfaced
withwood, compressed paper,plant bers,plastics,or
any material capable of igniting and burning, whether
ame-proofedornot,plasteredornon-plastered.
• Non-combustible Material - Material which will not
ignite and burn. Such materials are those consisting
entirely of steel, iron, brick, tile, slate, glass or plasters,
or any combination thereof.
• Non-combustible Sealant Material - Sealants which
will not ignite and burn: Rutland, Inc. Fireplace Mortar
#63, Rutland 76R, Nuex 304, GE RTV106 or GE
RTB116 (or equivalent).
E. Seasoned Wood
Burn only dry seasoned wood. Store wood under cover,

NOTICE: Improper operation can turn any wood
appliance into a smoldering environmental hazard.
Splitting wood before it is stored reduces drying time.
Woodshouldbestackedsothatboth endsofeachpiece
are exposed to air, since more drying occurs through the
cut ends than the sides. This is true even with wood that
has been split. Store wood under cover, such as in a shed,
or covered with a tarp, plastic, tar paper, sheets of scrap
plywood, etc., as uncovered wood can absorb water from
rain or snow, delaying the seasoning process.
F. Burning Process
In recent years there has been an increasing concern
about air quality. Much of the blame for poor air quality
has been placed on the burning of wood for home heating.
Inorder toimprovethe situation,weat VermontCastings
have developed cleaner-burning wood appliances that
surpass the requirements for emissions established by
our governing agencies. These wood appliances must be
properly operated in order to ensure that they perform the
way they are designed to perform.
1. Kindling or First Stage - Ithelpstoknowalittleabout
the actual process of burning in order to understand what
goesoninsideaappliance.Therststageofburningis
calledthekindlingstage.Inthisstage,thewoodisheated
to a temperature high enough to evaporate the moisture
which is present in all wood. The wood will reach the
boiling point of water (212°F) and will not get any hotter
until the water is evaporated. This process takes heat
from the coals and tends to cool the appliance.

if heat is robbed from the appliance during the drying
stage, the new load of wood has reduced the chances
for a good clean burn. For this reason, it is always best to
