What Wood to Burn
Your Frontier Series hydronic furnace operates with greatest efficiency when burning large, un-split,
seasoned wood logs. If the log fits in the door, it will burn. Small logs and split logs are fine too, but they
tend to burn faster and may reduce the burn time of the load.
NOTE:
1. Burn whole wood only. DO NOT burn coal, wood scraps, pallets, corn, pellets, garbage,
rubber, gasoline, oil products, or any other fuel. Failure to do so could result in voiding
your warranty.
2. DO NOT use chemicals, gasoline, lantern fuel, kerosene, charcoal lighter fluid or other
flammable liquids to start or “freshen up” the fire.
Seasoned wood produces much more useable heat for your home.
Do not burn unseasoned wood as it may cause creosote buildup,
marked reduction in heat output and visible smoke produced out
the stack. Seasoned wood has a moisture content of
approximately 20%, while freshly cut wood can contain in excess
of 60% moisture. The greener the wood, the more energy
diverted from heating your home.
Heat output varies with the species of wood burned, with hard
woods generally producing more heat than soft woods.
However, local availability is the most important factor in
selecting a wood to burn. We recommend using whatever wood
is most economically available in your area.
Useful tips to help you in buying wood:

A cord is a stack of wood 4 feet (1.22 m) high, 4 feet (1.22m) wide and 8 feet (2.44 m) long. The
gross cubic measurement of a cord of wood is 128 cubic feet (3.62 cubic meters). However, allowing
for air pockets, a cord is approximately 85 cubic feet (2.4 cubic meters) of solid wood.

On average, a pound of seasoned firewood produces 6050 BTUs (1.7 KW) of heat, regardless of
species. Wood that has only been seasoned for a short time will deliver about half as much heat.
Dense heavy wood delivers more heat per cord. Always compare the wood heating value before
purchasing your wood.

A good time to cut or buy green wood is in late winter or early spring. Cut it to length, stack it so that
air circulates through the pile, and shelter it from the weather. It is not recommended that you cover
wood with a tarp as this does not allow good air flow through the wood. Seasoning usually takes
about 18 months.

If you cut your trees in the spring or summer, leave the limbs attached until the leaves wither. The
withering process draws moisture from the wood. Then, cut the wood to the largest width that will
fit through the firebox door and the length of your firebox. The larger the log, the longer the fire will
hold.
Useable heat (measured in BTUs per lb)
from firewood drops substantially with
increased moisture content
