Yes, you can install a wood stove in a mobile home. However, the stove you install must have been specifically approved for mobile home applications. The stove must also be hooked up to a fresh air intake that enables combustion air to come from outside the house. Drolet models Adirondack, Eldorado, Jurassien EPA, Celtic, Savannah, Austral, and Baltic are approved for installation in a mobile home. You need to purchase a mobile home adapter, which can be found in the "accessories" section. Top of the Page
The chimney must comply with the building code of your country, state or province. It usually needs to be lined with refractory bricks, metal, or clay tiles sealed together with fire cement. The diameter of the chimney must be the same as the stove's flue outlet. If your masonry chimney does not have the same diameter as the stove's flue outlet, you need to insert a stainless steel liner having the proper diameter. Otherwise, you may face draft problems.

It is forbidden to modify a heater. Heaters are safety tested with a specific configuration, drawings of which are filed with the regulating authorities. Changing the type of door could lead to serious difficulties with your insurance company in case of fire. It would also automatically nullify your warranty. Top of the Page
There are numerous types of manufactured wood logs on the market. Some of them use chemical additives and those logs are generally prohibited for use in a wood stove. However, if you burn a manufactured log that is made of 100% wood, with no chemical additive, there is no problem. Wood is wood and the stove is designed to burn it. What we cannot control is the type of chemicals that can be inserted in different types of manufactured logs. The composition of the manufactured logs should be very clear on the log's packaging. If there are chemical additives, the log manufacturer should have a note on the log's packaging clearly stating that the use of the logs in a wood stove is strictly prohibited. Please note that manufactured logs burn hotter. We suggest that home owners try 2 or 3 logs first, and see how it goes. They should use a chimney thermometer and make sure that the flue temperature does not go into the "overheat" range. Manufactured logs have a lower density and the humidity level is generally lower. This is why they release more heat over a shorter period. Top of the Page
A chimney thermometer is highly recommended. It can prevent problems by providing you with an instant indication whether you are over-firing or under-firing your unit. Heating within the recommended temperature zone on the thermometer will favor a good draft and will help to reduce the build up of creosote in the exhaust system. Operating your heater at an abnormally low temperature favors the accumulation of creosote and therefore, the risk of a chimney fire. A thermometer will prove very useful especially if other members of your family are not as familiar with wood heating. The thermometer will help them to use the heater in a safe and efficient way. NOTE: double wall stove pipes require a thermometer with a probe. Top of the Page
Yes. A floor protector is required for any wood stove, unless the unit already sits on a non-combustible surface. You have many choices, such as stone, brick or tile. You need to consult your owner's manual in order to know the dimensions of the floor protector specific to your model. In general, the floor protector must extend in front of the unit by at least 18 inches (16 inches in the USA) and by at least 8 inches on the sides. Top of the Page
An ash drawer is a very practical feature, but it is not absolutely necessary. The ash drawer enables you to empty your stove and leave the ashes in the drawer until it is full. It makes cleaning more convenient and less messy. If you do not have an ash drawer, you can scoop out the ashes into a small bucket (with a cover) that you leave near the stove. ALWAYS MAKE SURE THAT THE EMBERS ARE COLD BEFORE DISPOSING OF THEM. Top of the Page
You first need to identify what your needs are. If you are looking for ambiance, a temporary heat source in a cottage or a camp, or a simple back-up heat source in case of power failure, you do not necessarily need to invest more money in order to buy an EPA certified wood heater. However, if your goal is to heat on a regular basis, the extra dollars will prove to be a good investment. Furthermore, it must be noted that EPA certified heaters release a significantly lower amount of particulates into the atmosphere, which makes wood a renewable and clean source of heat. As a result, if the style and size of heater you are looking for is available in an EPA-certified version, it is highly recommended that you invest in this advanced combustion technology. You will help the environment and save on wood consumption.
NOTE: If you live in the United Sates, British Columbia, Nova Scotia, or Newfoundland, EPA certified wood heaters are mandatory. Certain municipalities may also have by-laws that require the installation of EPA-certified wood heaters. Top of the Page
In the case of EPA certified stoves, there are generally two air intakes on the stove: primary and secondary. The exhaust gases are mixed with secondary air, causing them to re-ignite and burn before going up the chimney. The result is a reduction in particulate emissions, as well as an increased burn time. Some EPA certified stoves also work with a catalytic converter. Instead of using secondary air, the smoke is channeled through a device that lowers the combustion temperatures of the gases. This allows gases to be consumed at lower firing. Catalytic converters need to be replaced after a certain number of operations and can be costly. Non-EPA wood stoves usually have only one air intake and have no catalytic converters. Top of the Page
Before answering this question, it is very important that you clearly identify what your needs are. Some people will buy a heater simply to enhance the ambiance of a room, while others will buy a heater as their main source of heat. There is no good or bad reason for buying a wood-heat system. If you simply want to enhance the ambiance of a room, most small to medium size heaters will suit your needs. Simply chose the style you like best, and put the unit in the room where you spend the most time. The heat and look of a glowing fire will create an atmosphere of warmth and well-being.
If your primary need is heat, you must verify the heating capacity of your heater based on the technical data provided by the manufacturer. For instance, if you want to heat a 800 square foot area, you need to buy a heater with a minimum capacity of 800 sq. ft.
If you need to heat more than one floor, keep in mind that heat rises. Therefore, a heater located in your basement will help you heat the main floor as well. However, the contrary is not true; a heater located on the main floor (ground floor) will not heat the basement. Keep in mind also that the more divisions there are in the house, the harder it will be to distribute the heat evenly.
If you need to heat two floors, calculate the surface of the lower floor. Then, add 50% of the surface of the upper floor. For instance, if you install a wood-heat system in the basement and you have 800 sq .ft., you will need a heater with a minimum capacity of 1,200 sq .ft. (800 + 400 = 1,200).
If you need to heat more than two floors, calculate the surface of the lower floor (where the wood-heat system is located). Then, add 50% of the surface of the middle floor, and 25% of the surface of the upper floor. For instance, if you install a heater in the basement and you have 800 sq .ft., you will need a heater with a minimum capacity of 1,400 sq .ft. (800+400+200= 1,400). Consult drawing #1A. It will help you understand the explanations provided in this section.
PLEASE NOTE: We are talking about "zone" heating, not central heating. The room where the heater is located and the rooms directly above it will always reach higher temperatures than the rooms distant from the unit. If you want an even temperature throughout the house, you need to consider a central heating system, such as a wood furnace. Furthermore, you must keep in mind that the size of the stove you need may vary based in the insulation of your house, its exposition to wind, and the number of windows. It will always be prudent to buy a heater with a capacity that is slightly higher than the minimum capacity that you need. For instance, if you need a minimum capacity of 1,400 sq .ft., it will be more prudent to buy a heater with a capacity of 1,500 to 1,600 sq .ft.
Drawing #1 gives an example of the minimum heating capacity required for a wood-heat system installed in a house with three floors of 800 sq .ft. each. We assume that the house is well insulated and that air can circulate between each floor through an open stairway and/or floor traps. Top of the Page
Before you read this section, please take note that the information supplied in the table below is based on Canadian standards and may not apply to other countries.
The minimum clearances can be reduced by installing a protective shield. The shield can be made of various non-combustible materials, such as ceramic, brick or metal. After installing a heat shield, the minimum clearances indicated on the heater's certification plate can be reduced, as summarized in the table below:
|TYPE OF PROTECTION||Percentage of clearance reduction using shielding|
|SIDES AND BACK||TOP|
|Sheet metal, with minimum thickness of 0,013" (0,33mm), spaced out by at least 1" (25.4mm) by non-combustible spacers.||67%||50%|
|Ceramic tiles, or an equivalent non-combustible material installed on a non-combustible support, spaced out by at least 1" (25.4mm) by non-combustible spacers.||50%||33%|
|Ceramic tiles, or an equivalent non-combustible material installed on non-combustible supports with a minimum of 0,013" (0,33mm) sheet metal backing spaced out by at least 1" (25.4mm) by non-combustible spacers.||67%||50%|
|Brick, spaced out by at least 1" (25.4mm) by non-combustible spacers.||50%||N / A|
|Brick, with a minimum of 0,013" (0,33 mm) sheet metal backing spaced out by at least 1" (25.4mm) by non-combustible spacers.||67%||N / A|
All heaters manufactured by SBI are certified as per the latest CSA (Canadian Standard Association) and UL / ULC standards (Underwriters Laboratories / Underwriters Laboratories of Canada). Model Hunter is the only exception since it is strictly designed for recreational purposes.
An independent laboratory is responsible for testing each model as per the applicable standards. Warnock Hersey and Omni Test Laboratories (OTL) are the independent labs most frequently used and their name generally appears on the certification label attached to the side or back of each heater.
All heaters sold in the USA meet the latest emissions standards required by the EPA (Environmental Protection Agency). Each EPA-certified heater has been tested for emissions by an independent laboratory. Top of the Page
The word "draft" refers to the hot air movement that circulates in your stove's exhaust system, going from the stove to the outside of the house, and carrying with it the combustion residues. The draft is a natural phenomenon. Hot air weighs less than cold air, causing it to rise. This is why the higher the temperature in the exhaust system, the stronger the draft. It is also important to say that the "tunnel effect" created by the exhaust system contributes to increasing the draft effect. This is why chimneys that are excessively long often create excessive draft, while chimneys that are abnormally short will have an excessively low draft.
"Negative pressure" can be seen as a "reverse draft". That is, air will circulate from the chimney toward the interior of the house. Negative pressure is often what causes smoking problems. In general, negative pressure is the result of either one or a combination of the three factors explained below:
A cold chimney. Cold air, which is heavier that hot air, has a tendency to go down the chimney and create the effect of a "clog". This explains why a stove that has not worked for a long time and which chimney is very cold will sometimes be hard light.
Negative pressure can also occur as a result of a "vacuum effect" in the room or the house. The air in a house is constantly moving. Hot air rises, cold air moves down. Air can also be expelled outside of the house with the use of air-moving equipment, such as a range hood, a air exchanger, a bathroom fan, a dryer, etc. Furthermore, air goes in and out of the house through cracks, doors, windows, etc. If air leaves a room without being replaced, a "vacuum effect" is created. Therefore, if a house is well insulated and all windows are closed, the room will source its air through the easiest alternative route, which is often your stove's exhaust system. This creates a negative pressure in your exhaust system. You now understand why it is often suggested that a window be slightly open in the room where the stove is located. This enables the room to easily source its air outside the house without searching for an alternative route. The vacuum effect can be amplified when your stove is located in the basement. This is due to the fact that your house itself acts like a chimney. Since hot air will rise to upper floors in the house, it will "draw" air from the basement of the house. This is called the "chimney stack effect".
Wind can also be a third cause of negative pressure. When your house is located near a structure which height is superior to your chimney's, wind currents can create an interference with your chimney, leading to negative pressure problems.
DRAWING #1B shows a stove functioning under normal and adequate conditions. Heat rises to the upper floors and the room where the stove is located has an adequate supply of oxygen. The chimney draft is sufficient and the combustion gases are evacuated normally through the exhaust system.
DRAWING #2B DRAWING #2B shows the effect of a cold chimney. Cold air creates a reverse draft (negative pressure), which causes smoking problems. This phenomenon is amplified by the fact that heat rises, which creates a draft from the basement of the house to the upper floors ("chimney stack effect").
DRAWING #3B DRAWING #3B shows the effect of negative pressure caused by an air-moving device inside the house. In the example above, the range hood draws air from inside the house, which is replaced by air coming from the chimney. The result is a smoking problem.
DRAWING #4B DRAWING #4B shows the negative pressure effect caused by wind, influenced by nearby structures such as a building.
DRAWING #5B DRAWING #5B shows the negative pressure effect that can be caused by wind, influenced by nearby structures such as a tree.
DRAWING #6B DRAWING #6B shows the minimum height that the chimney should have, considering adjacent structures located within a horizontal distance of 10 feet.Top of the Page
Those three letters stand for "Environmental Protection Agency". The Environmental Protection Agency is an American organization that elaborates and coordinates the application of laws which goal is to protect the environment. EPA certified wood stoves meet emissions guidelines set by the Environmental Protection Agency. EPA certified wood stoves will generally release less particulates into the atmosphere and will provide a longer burn time. Top of the Page
The CSAB415.1 is the Canadian equivalent of the EPA standard. Therefore, with regards to wood-burning space heaters, such as a stove or fireplace, a unit meeting the EPA standard also meets the CSAB415.1 standard. Top of the Page
Your exhaust system is comprised of two main elements: a chimney and a connector (commonly called "stove pipe"). There are two types of chimneys: a Class A metal chimney or a masonry chimney. Class A chimneys are rated to withstand temperatures up to 2100oF and are easy to install. The connector is made of steel and needs a minimum thickness of 24ga. You can also use a double wall connector that will enable you, in most cases, to reduce clearances to combustible materials. The connector cannot go through ceilings, closets, floors, or any other combustible partition. It is the chimney that goes through combustible partitions and that goes out to the exterior of the house, according to the chimney manufacturer's specifications. Top of the Page
You will notice a difference between the BTU output as indicated on the unit's white EPA label and what is advertised on our web site and/or product literature. The maximum BTU output we advertise for this unit is what will be obtained with a full load of seasoned cordwood inserted inside the firebox. The EPA output, on the other hand, is what has been obtained during emissions testing. The EPA test procedure requires that a special type of wood be used and positioned inside the firebox in a manner that does not represent the way the firebox volume would normally be utilized using seasoned cordwood. The EPA test load is typically much smaller. Hence, the BTU as per the EPA label is reduced. The BTU output that should be considered by a normal user is the one we advertise for seasoned cordwood.

Why is the efficiency reported on the white tag affixed to the appliance different than the efficiency published on the web site?
First, it is important to mention that the efficiency calculation is not mandatory in North America. Manufacturers that have tested their appliances to the EPA Standard must report a "default" efficiency on the little white EPA tag that must be affixed to the appliance. This is why you will see a 63% efficiency rating on that EPA tag. The real efficiency of EPA-certified units, however, is normally between 70% and 80%. It is possible for manufacturers to test their appliances for efficiency. Manufacturers that report an efficiency rating higher than 63% have probably had their appliances tested through an independent laboratory. Although there exist more than one efficiency calculation method, the one generally recognized by North American manufacturers is the Canadian CSAB415.1 method. Our appliances have all had their efficiency tested per that method. You will notice that the vast majority of our appliances have an efficiency rating between 70% and 85%. Top of the Page
A blower can be installed at the back of most models. This option enables you to redistribute the heat from the back of your heater to the front of it and into the room. By forcing hot air toward the front of the heater, the blower extends the radiation power of your unit. If you do not have a blower and would like to purchase one, please consult our " accessories " section.
