3. Final Stage

The ﬁnal stage of burning is the charcoal stage. This occurs when the ﬂammable gases have been mostly burned and only charcoal remains. This is a naturally clean portion of the burn. The coals burn with hot blue ﬂames.

•It is very important to reload your appliance while enough lively hot coals remain in order to provide the amount of heat needed to dry and rekindle the next load of wood.

•It is best to open the Primary Air Control and the Start-Up Air Controls before reloading. This livens up the coal- bed and reduces excessive emissions (opacity/smoke).

•Open door slowly so that ash or smoke does not exit ap- pliance through opening.

•Break up any large chunks and distribute the coals so that the new wood is laid on hot coals.

Air quality is important to all of us, and if we choose to use wood to heat our homes we should do so responsibly.

We need to learn to burn in the cleanest way possible al- lowing us to continue using our wood appliances for many years to come.

E. Air Controls

Start-Up Air System

The combustion air enters at the rear of the ﬁrebox through the rear air tubes. This air supply is controlled by the Start- up Air Control. For more air push control IN, for less air pull control OUT.

Primary Air System

The primary air enters below the ash catcher and is directed to the upper front of the ﬁrebox, near the top of the glass door and to the lower front of ﬁrebox. This preheated air sup- plies the necessary fresh oxygen to mix with the unburned gases, helping to create secondary, tertiary and quaternary combustions. This air is regulated by the Primary Air Slide Control. For more primary air slide control LEFT, for less air slide control RIGHT.

D. Combustible/Non-Combustible Materials

•Combustible Material

Material made of or surfaced with wood, compressed paper, plant ﬁbers, plastics, or any material capable of igniting and burning, whether ﬂame-proofed or not, plastered or unplastered.

•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.

Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnance at 750 oC and UL763 shall be considered non-combustible materials.

•Non-Combustible Sealant Material

Sealants which will not ignite and burn: Rutland, Inc. Fireplace Mortar #63, Rutland 76R, Nuflex 304, GE RTV106 or GE RTB116 (or equivalent).

WARNING

Fire Risk.

•ALWAYS OPERATE THIS APPLIANCE WITH THE DOOR CLOSED AND LATCHED EXCEPT DURING START-UP AND RE-FUELING OR WHEN USING THE FIRESCREEN.

•OPERATING WITH THE DOOR PARTLY OPEN CAN CAUSE:

•HOT EMBERS OR SPARKS TO FALL OUT

•FLAMES AND SMOKE MAY BE DRAWN OUT FROM FIREBOX OPENING

CUMBGAP-MBK, CUMPGAP-PMH specifications

The Quadra-Fire CUMPGAP-PMH and CUMBGAP-MBK are established models in the realm of high-efficiency wood stoves, combining modern technology with traditional heating methods to provide an effective and environmentally friendly heating solution.

One of the standout features of the CUMPGAP-PMH and CUMBGAP-MBK models is their impressive heating efficiency. Both stoves exceed industry standards, ensuring that more heat is produced from less fuel, which not only helps in saving on heating costs but also reduces the environmental impact. Their efficient combustion technology means that these stoves produce minimal emissions, making them a responsible choice for eco-conscious consumers.

The construction of these stoves is designed with durability and robustness in mind. Made from high-quality materials, they assure longevity and reliability, which are crucial elements in heating appliances. The intelligently engineered airflow dynamics facilitate efficient burning, allowing these models to maintain optimal performance under various conditions.

Another significant feature of both models is the incorporation of advanced catalytic combustors. These catalysts improve the combustion process, resulting in cleaner burning and enhancing overall efficiency. The catalytic technology functions by allowing smoke and gases to pass through the catalyst, where they undergo additional burning before being released into the atmosphere. This process not only maximizes heat generation but also significantly lowers the emissions of harmful pollutants.

User convenience is also a top priority with these wood stoves. They feature large ash pans and simple loading mechanisms, making it easy to maintain and use them regularly. Their stylish design allows them to fit seamlessly into any home décor, and with variable heating capacities, they can effectively warm spaces of different sizes.

Safety features are another vital characteristic of the CUMPGAP-PMH and CUMBGAP-MBK models. With built-in heat shields and thermal protection, they provide peace of mind to homeowners while promoting safer operation. Additionally, they comply with various safety and efficiency standards set by regulatory bodies.

In conclusion, the Quadra-Fire CUMPGAP-PMH and CUMBGAP-MBK models stand out for their efficiency, design, advanced combustion technology, and safety features. They offer a modern solution to traditional wood heating, ensuring warmth and comfort while taking care of the environment. These stoves represent the perfect synergy of innovation and effectiveness in home heating solutions.
