You have purchased a Hearthstone Heritage 8024 tested to EPA Method 28R 40 CFR Part 60 where applicable. This stove
is certified to comply with the U.S. Environmental Protection Agency 2020 particulate emissions standard using crib wood. It
is certified at 0.54 gr/hr. emission rate and under specific test conditions has been shown to deliver heat at rates ranging
from 12,317 to 35,845 Btu/hr (output).
This wood heater has a manufacturer-set minimum allowable low burn rate that must not be altered. It is against federal
regulations to alter this setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in
this manual.
Please refer to the Warranty section of this manual for registration instructions. In case of warranty claims, please contact
the point of original sale or the nearest authorized Hearthstone dealer. Our dealer network processes all warranty claims.
Authorized Hearthstone dealers can be located at www.hearthstonestoves.com.
This heater is designed to burn natural wood only. Higher efficiencies and lower emissions generally result when burning
air-dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods.
DO NOT BURN:
Garbage,
lawn clippings, material containing rubber (including tires), materials containing plastic, waste petroleum products paints or
paint thinners, asphalt products, materials containing asbestos, construction or demolition debris, railroad ties, pressure
treated wood, manure or animal remains, salt water driftwood or other previously salt water saturated materials, unseasoned
wood, paper products, cardboard, plywood or particleboard.
This prohibition against burning these materials does not
prohibit the use of fire starters made from paper, cardboard, sawdust, wax and similar substances for the purpose of starting
a fire in an affected wood heater. Burning these materials may result in a release toxic fumes, render the heater ineffective,
cause smoke and may damage catalysts.
Following the maintenance guidelines set forth in this manual will help insure the efficient use of your wood heater and
minimize visible emissions. Having your stove inspected by a trained professional on a regular basis will greatly increase the
potential for recognizing possible impacts to efficiency.
Proper draft is important to the efficient operation of your heater. Refer to the Normal Operation section of this manual for
information regarding adequate draft. Both excessive and sub-minimum draft can affect the efficiency of your wood heater.
Excessive draft can lead to over-consumption of fuel, lower overall heating capacity of the stove and potential over firing.
Low draft can result in inefficient burns, low heat output, expulsion of smoke into the living area when stove doors are
opened and an increased potential for build-up of flammable materials in the flue.
Efficiency:
Efficiency was measured and weighted using EPA Method 28R and CSA B415-10 methodology. A weighted average was
used to calculate the overall efficiency across all of the 4 burn rate categories using the higher heating value (HHV). The
weighted average efficiency is 77.1% (HHV).
To maximize the efficiency of your wood stove make sure it is sized properly for the space you plan to heat. An oversized
stove will often be forced to burn at a lower and dirtier burn rate. Consult with your dealer for sizing and correctly placing the
stove in your home. An incorrectly placed stove can greatly reduce efficiency. Maximizing the efficiency of your stove will
heat your house quickly, burn cleaner and use less wood.
Refer to the Choosing Firewood section of this manual for appropriate fuel selection. Seasoned firewood is typically at or
near 20% moisture content. This can be measured with any number of hand-held moisture meters available through your
local hearth shop. Follow instructions included with the meter you purchase to measure fuel wood moisture content. Burn
only dry, seasoned wood as using wet wood will greatly reduce your efficiency.
CO Emissions:
The Heritage 8024 has the following CO emission rates by burn level: Category 1 (low)
– 0.11 g/min, Category 2 (med. low)
– 0.25 g/min, Category 3 (med. high) – 0.10 g/min, and Category 4 – 4.12 g/min. Wet wood or unapproved fuel described
above can greatly affect the emissions of a wood burning stove.
Smoke/Fire/CO Detectors:
It is highly recommended that smoke and CO detectors be installed throughout the heated space when a wood burning
heater is installed. Be certain to install these devices not only in the area where the wood appliance is located, but also in
bedrooms, hallways leading to other areas of the house and all common areas of the heated space. Check the batteries in
these devices and assure operation by performing whatever test operations are recommended by the manufacturer.
