2.3.4 Fuel Selection
(a) Instructions on acceptable fuels;
(b) Warning against inappropriate fuels; and
(c) How to determine seasoned wood compared to unseasoned wood, how to use moisture meters and other techniques and the importance of seasoned wood.
Exhibit 3 - Example Text covering 2.3.4(a) and (b) of this appendix:
“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:
(8) Railroad ties or pressure-treated wood;
(9) Manure or animal remains;
(10) Salt water driftwood or other previously salt water saturated materials;
(11) Unseasoned wood; or
(12) Paper products, cardboard, plywood, or particleboard. The prohibition against burning these materials does not prohibit the use of fire starters made from paper, cardboard, saw dust, wax and similar substances for the purpose of starting a fire in an affected wood heater.
Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.”
2.3.5 Achieving and Maintaining Catalyst Light-Off
Owner's manuals must describe in detail proper procedures for:
(a) Operation of catalyst bypass (stove specific);
(b) Achieving catalyst light-off from a cold start; and
(c) Achieving catalyst light-off when refueling.
2.3.5.1 No example text is supplied for describing operation of catalyst bypass mechanisms (Item 2.3.5(a) of this appendix) since these are typically stove-specific. Manufacturers must provide instructions specific to their model describing:
(1) Bypass position during startup;
(2) Bypass position during normal operation; and
(3) Bypass position during reloading.
Exhibit 4 - Example Text for Item 2.3.5(b) of this appendix:
“The temperature in the stove and the gases entering the combustor must be raised to between 500° to 700 °F for catalytic activity to be initiated. During the startup of a cold stove, a medium to high firing rate must be maintained for about 20 minutes. This ensures that the stove, catalyst, and fuel are all stabilized at proper operating temperatures. Even though it is possible to have gas temperatures reach 600 °F within 2 to 3 minutes after a fire is started, if the fire is allowed to die down immediately, it may go out or the combustor may stop working. Once the combustor starts working, heat generated in it by burning the smoke will keep it working.”
Exhibit 5 - Example Text for Item 2.3.5(c) of this appendix:
“REFUELING: During the refueling and rekindling of a cool fire, or a fire that has burned down to the charcoal phase, operate the stove at a medium to high firing rate for about 10 minutes to ensure that the catalyst reaches approximately 600 °F.”
2.3.6 Catalyst Monitoring
(a) Recommendation to visually inspect combustor at least three times during the heating season;
(b) Discussion on expected combustor temperatures for monitor-equipped units; and
(c) Suggested monitoring and inspection techniques and importance of ensuring catalyst is operating properly.
Exhibit 6 - Example Text covering 2.3.6(a), (b) and (c) of this appendix:
“It is important to periodically monitor the operation of the catalytic combustor to ensure that it is functioning properly and to determine when it needs to be replaced. A non-functioning combustor will result in a loss of heating efficiency, and an increase in creosote and emissions. Following is a list of items that should be checked on a periodic basis:
• Combustors should be visually inspected at least three times during the heating season to determine if physical degradation has occurred. Actual removal of the combustor is not recommended unless more detailed inspection is warranted because of decreased performance. If any of these conditions exists, refer to Catalyst Troubleshooting section of this owner's manual.
• This catalytic (or hybrid) heater is equipped with a temperature probe to monitor catalyst operation. Properly functioning combustors typically maintain temperatures in excess of 500 °F, and often reach temperatures in excess of 1,000 °F. If catalyst temperatures are not in excess of 500 °F, refer to Catalyst Troubleshooting section of this owner's manual.
Step 1 - Light stove in accordance with instructions in section 3.3.5.
Step 2 - With smoke routed through the catalyst, go outside and observe the emissions leaving the chimney.
Step 3 - Engage the bypass mechanism and again observe the emissions leaving the chimney.
Significantly more smoke will be seen when the exhaust is not routed through the combustor (bypass mode).”
2.3.7 Catalyst Troubleshooting
The owner's manual must provide clear descriptions of symptoms and remedies to common combustor problems and importance. It is recommended that photographs of catalyst peeling, plugging, thermal cracking, mechanical cracking, and masking be included in the manual to aid the consumer in identifying problems and to provide direction for corrective action.
2.3.8 Catalyst Replacement
The owner's manual must provide clear step-by-step instructions on how to remove and replace the catalytic combustor. The section should include diagrams and/or photographs.
2.3.9 Wood Heater Proper Operation and Maintenance
The owner's manual must provide clear descriptions of symptoms and remedies to common heater problems and importance. The owner's manual information must be adequate to enable consumers to achieve optimal emissions performance. Such information must be consistent with the operating instructions provided by the manufacturer to the approved test laboratory for operating the wood heater during certification testing, except for details of the certification test that would not be relevant to the user.
Owner's manual must include:
(a) Recommendations about building and maintaining a fire, especially for cold starts and the effectiveness of the top-down approach for starting fires;
(b) Instruction on proper use of air controls, including how to establish good combustion and how to ensure good combustion at the lowest burn rate for which the heater is warranted;
(c) Ash removal and disposal;
(d) Instruction replacement of gaskets, air tubes and other parts that are critical to the emissions performance of the unit, and other maintenance and repair instructions;
(e) Warning against overfiring; and
(f) Suggested monitoring and inspection techniques and importance of ensuring heater is operating properly, including ensuring visible emissions are minimized.
2.3.9.1 No example text is supplied for 2.3.9(a), (b), (d) and (f) of this appendix since these items are model specific. Manufacturers should provide detailed instructions on building and maintaining a fire including selection of fuel pieces, fuel quantity and stacking arrangement. Manufacturers should also provide instruction on proper air settings (both primary and secondary) for attaining minimum and maximum heat outputs and any special instructions for operating thermostatic controls. Step-by-step instructions on inspection and replacement of gaskets should also be included. Manufacturers should provide diagrams and/or photographs to assist the consumer. Gasket type and size should be specified.
Exhibit 7 - Example Text for Item 2.3.9(c) of this appendix:
Exhibit 8 - Example Text covering Item 2.3.9(e) of this appendix:
2.3.10 Wood Heater Installation, Including Stack Height, Heater Locations and Achieving Proper Draft
(a) Importance of proper draft;
(b) Conditions indicating inadequate draft;
(c) Conditions indicating excessive draft; and
(d) Guidance on proper stack height and proper heater locations, i.e., not too close to neighbors or in valleys that would cause unhealthy air quality or nuisance conditions.
2.3.10.1 No example text is supplied for (d) because state, local and tribal requirements are model and location specific.
Exhibit 9 - Example Text for Item (a):
“Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your chimney depends on the length of the chimney, local geography, nearby obstructions and other factors. Too much draft may cause excessive temperatures in the appliance and may damage the catalytic combustor. Inadequate draft may cause backpuffing into the room and `plugging' of the chimney or the catalyst.”
Exhibit 10 - Example Text for Item (b):
Exhibit 11 - Example Text for Item (c):
“An uncontrollable burn or excessive temperature indicates excessive draft.”
2.3.11 Efficiency
(a) Description of how the efficiency was determined, e.g., use higher heating value of the fuel instead of lower heating value of the fuel, discuss sweet spot versus annual average versus annual fuel usage efficiency (AFUE);
(b) How operation and fuels affect efficiency, e.g., seasoned wood versus high moisture fuel; operation at sweet spot versus low-burn rates; and
(c) How location affects the efficiency, e.g., in main living area versus basement versus outdoors in sub-freezing temperatures.
2.3.12 Smoke and Carbon Monoxide Emissions and Monitors
(a) Discussion of smoke and carbon monoxide (CO) emissions, including the CO data submitted in the certification application and expected variations for different operating conditions;
