PELLET QUALITY
The performance of your pellet appliance is greatly affected by the type and quality of wood pellets burned.
Your Hearthland Stove is designed to burn wood pellets that meet Pellet Fuel Institute standards for
"Premium" or "Standard" quality wood pellets. Wood pellets falling below or outside these standards will re‐
sult in reduced performance. Note: Store wood pellets in a dry location to prevent them from absorbing ex‐
cess moisture.

Ash Content:
‐ Standard Quality 3% by weight, maximum, (1.2 lb per 40 lb of pellets.)
FINES:
Fines in pellets are small pieces of sawdust or broken down pellets that are small enough to pass through
square mesh screen with 1/8" spacing. Pellets can break down from handling, transporting and/or storage.
Fines adversely affect the pellet feed system and combustion system greatly increasing the requirements for
periodic cleaning.
SCREENING:
Excessive fines can be removed from pellets through a process called "screening". This can be
accomplished by pouring pellets down an incline of 1/8" mesh screen into a container or hopper. This process
will allow the good pellets to flow into the container while the fines fall through the mesh to be discarded.
PELLET CONSUMPTION:
tion to maintain the exhaust temperature to a set level. Factors affecting consumption rate depend on factors
such as:
⇒
Fuel BTU Content: Typically wood pellets contain 7,000 to 8,700 BTU's per pound. Higher BTU content
will burn at a lower rate than lower BTU content pellets.
⇒
FAN SPEED setting: Higher FAN SPEED settings (room heat) will draw more heat from the heat ex‐
changer, causing an increased fuel consumption rate than at lower FAN SPEED settings.
⇒
Heat Exchanger Cleanliness: Ash build‐up on heat exchange tubes and heat exchange back panel will
significantly reduce heat transfer to convection air causing fuel consumption rates to reduce. It is impor‐
tant that heat exchanger be kept clean for efficient heat transfer to convection air (room heat).
⇒
Excessive Combustion Air: Excessive combustion air will result in increased fuel consumption.
⇒
Air Circulation: Settings with good air circulation will yield more efficient heat transfer to convection
air a resulting in increased fuel consumption over settings with poor air circulation.
