A: Pellet quality is important, please read the following:
Your Wolf Steel Ltd. Pellet Appliance has been designed to burn premium hard or soft wood pellets only. Do not use any other type of fuel such as fire logs or fire starting pellets.
The performance and heat output of the pellet appliance is directly related to the quality and moisture of the pellets. Store pellets in a cool dry area to prevent moisture absorption. If the fuel does not comply to this standard the appliance may not operate as designed.
We recommend the use of premium grade (1% ash content) for longer appliance life and less frequent cleaning.
Upon changing the batteries in the remote and the receiver, it may be necessary to replace the remote system. Remote systems are warrantied for one year.
Maximum steady state efficiency is determined by specific test conditions that include burning the fireplace until the fireplace and flue gas (exhaust) temperatures reach equilibrium, which means that there is no further change in temperatures. Temperatures, taken from a specific location, reflect the amount of heat being exhausted, which is then subtracted from the predetermined input of the burner. The remaining amount of heat represents the highest amount of heat that the fireplace can transfer into the surrounding area. Example, our natural gas stove, the GDS50 has a BTU input of 44,000 BTU. The maximum efficiency is 84%. 44,000 x 84% = 36,960 BTU output.
BTU’s (British Thermal Units) are a standard of measurement which represent the heat value of any type of energy used to create heat. The amount of fuel that a fireplace will consume per hour is calculated with the BTU value of the fuel it uses to determine the input of that fireplace. BTU values of any type of energy are determined by the actual amount of heat required to increase the temperature of one pound of water, by one degree Fahrenheit.
Annual Fuel Utilization Efficiency is also determined by the results of some specific test conditions but these results are further calculated with other influences such as average daytime and nighttime temperatures, heat loss due to the standing pilot and from cold start up. All sorts of data is calculated to provide the overall average efficiency of the fireplace throughout the year.
Radiant heat is transmitted from a heat source via rays just like rays of sunlight. These rays pass through the air without heating it since only solid objects can absorb the heat they transmit. Dark colours absorb more radiant heat than lighter colours which reflect more of it. This is why light coloured clothing is cooler than dark coloured clothing. All our Napoleon Fireplaces are designed to generate radiant heat into your living room.
This is the transfer of heat through a body or substance. All of our fireplaces conduct heat to the air as it comes into contact with the hot glass and firebox surface.
This describes the transfer of heat by heating, then moving a substance. Simply put, the heat from our fireplaces is distributed via convection. This is when the air in front of the fireplace absorbs heat, becomes buoyant and rises to the ceiling. This draws cooler air behind it, mostly along the floor, which in turn, absorbs the heat and rises up, pushing the already warmed air along the ceiling. As long as there is a source of heat, this cycle will continue, constantly raising the overall temperature of the room.
The term Zero Clearance indicates that the particular fireplace can be enclosed using combustible materials. Depending upon the limitations of a specific zero clearance fireplace, These combustible building materials may allowed to be installed against the body of the fireplace without fear of combustion or heat damage. However, some fireplaces may require installation using non-combustible materials such as metal studs and framing for the parts of the enclosure in the immediate vicinity of the fireplace. Please have a professional install your fireplace following the parameters presented in the installation instructions to ensure that it is installed using the correct materials.
Zero Clearance does not mean that you can place objects like furniture in front of or against the front of your fireplace. Furniture and curtains, etc. should remain at least 48-inches from the front of your fireplace for safety.
Direct vent is a term used to describe a specifically designed fireplace that performs differently from the traditionally vented fireplace which use a chimney. This type of fireplace has a completely sealed combustion chamber which allows it to vent directly out a side wall of the home. One of the benefits of this type of design is that it must draw air necessary for combustion from the outside since the sealed combustion chamber does not allow air to be drawn in from around the fireplace. The co-axial vent system has the exhaust pipe within the air intake pipe which protects any surrounding combustible material from the high temperature of the flue gases as well as preheating the outside air prior to it being introduced to the combustion process.
These type of fireplaces do not have a sealed combustion chamber and relies on the buoyancy of hot gases to vent effectively. They must be installed either with an existing chimney that meets the local building code standards or they can be installed using a B vent which is a vent pipe that must be installed to the same parameters of a masonry chimney but can be enclosed in combustible material. They draw air (oxygen) necessary for combustion from the area surrounding the fireplace. The combustion by-products or flue gases are hot and naturally rise up through the chimney which provides a route for these hot gases to escape from the house. As the fireplace continues to vent these flue gases up the chimney, the walls of the chimney heat up, which allows the flue gases to retain more of their temperature and buoyancy thereby increasing the speed with which they exit the chimney.
Vent free fireplaces are fireplaces that do not require any type of vent system. Instead, they are designed to burn clean and the combustion by-products allowed to flow into the room the fireplace is located in. Stringent requirements ensure that these fireplaces not only burn cleanly, but that they are located in rooms of sufficient size to ensure an adequate supply of fresh air is always available for the combustion process. A highly sensitive sensor is employed to turn off the gas to the fireplace should the level of oxygen within the area begin to deplete. The most obvious benefit of this type of system is that no heat is lost through the venting system making the fireplace virtually 100% efficient. Currently, these type of gas fireplaces can only be installed in some areas of the United States. They are not approved for use in Canada.
