THE NEW GENERATION OF FURNACES
Known for its exceptional performance, the Caddy Advanced is a furnace that’s innovative design (patent pending) is surpassed only by its simplicity of use.
DISCOVER SELF-REGULATED COMBUSTION
The self-regulated combustion of the Caddy Advanced promises constant heat, while requiring minimal effort on your part; just fill the furnace, adjust the temperature and enjoy the heat for hours! The system automatically adjusts the air supply so that combustion is optimized and synchronized with the thermostatic demand.
- At start-up, the furnace injects additional combustion air for easy and quick ignition.
- As the furnace goes into heating mode, it automatically adjusts the combustion air supply and the operation of the convection blower. When your home’s desired temperature is reached (thermostat setting), the furnace goes into energy saving mode, automatically reducing the combustion air and speed of the convection blower.
- At the end of the combustion cycle, if the furnace needs to go back to heating mode (thermostat setting), additional combustion air is injected again to activate the combustion of the embers thus providing a hotter burn on the end of the combustion cycle.
EASE OF USE
Use the Caddy Advanced with confidence thanks to its intuitive operation and illustrated quick user guide. Equipped with a glass door allowing you to easily monitor the state of combustion, the furnace optimizes its combustion cycle: you will spend much less time taking care of it vs a conventional furnace (loading wood, adjusting the air, etc.). This optimization also ensures you substantial savings in firewood as well as increased comfort thanks to the production of constant heat throughout the combustion cycle.
Among the most efficient furnaces in terms of energy distribution, the Caddy Advanced has one of the lowest minimum burn rates in the industry. This means a load of wood burns longer, and therefore reduces the frequency of wood loading. Emissions on this unit are amongst the cleanest of the few EPA 2020 certified furnaces, and yet the Caddy Advanced is among the most energy efficient on the market. In addition, the new ECM motor blower option consumes 40% less electricity (and much quieter) than a standard PSC motor blower.
QUICK AND FLEXIBLE INSTALLATION
The Caddy Advanced is equipped with pre-wired electrical components that allow for quick and hassle-free installation. For more flexibility, you can install the filter supports on either sides and on top of the blower box to adapt the layout of the ventilation ducts to your space. In addition, the add-on configuration allows you to install the Caddy Advanced with your existing electric, oil or gas central heating system to take advantage of an alternative energy source.
The Caddy Advanced includes a tool set and wall support, an ash lip, a thermostat, a moisture reader, a barometric damper and a fresh air intake adapter.
Alternate source of heat
Always have an alternate source of heat to ensure the comfort and safety of your family. The Caddy Advanced comes in two different configurations: wood-only and wood add-on furnace.
When installed as an add-on furnace, only a SERIES configuration is allowed only in Canada and the blower is not required. | Only PARALLEL configuration is allowed in the USA.
This furnace can be installed as a wood-only unit. Blower box with regular or ECM motor is required for this configuration.
If you’ve already got an oil, gas, or electric central heating system but want to add the flexibility of wood, the Caddy Advanced wood add-on furnace is for you. This unit, which installs on either side of your existing system, uses the same controls and fan as your existing furnace, giving you a fully compatible wood+oil, wood+gas, or wood+electric combo system.
100% of the first 4 product owners who have registered their warranty are satisfied with this product.
12 hours of even heat on a bitterly cold, windy day and I only touched the furnace once . . . For people who heat with wood, this is genuinely life changing!

How do I reduce the amount of charcoal my heater produces?
Appliances that are EPA or CSAB415.1 certified tend to create larger coal beds due to their higher efficiency. This can be controlled by the way you burn your appliance. After an overnight burn, you may have a more significant coal bed. Simply rake the coal bed forward and add a smaller piece of wood on top. Burn the appliance on a higher setting (air control fully open). This will pull more primary air into the firebox and will increase draft. The coal bed will burn down with the log. You may have to repeat this operation a couple of times before the coals are reduced. You are then ready to load your appliance with a larger fuel load.
Do I need an EPA certified or CSAB415.1-10 certified heater?
You first have 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 or CSAB415.1-10 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 certified heaters release up to 90% less particles into the atmosphere, which makes wood a renewable and clean source of heat. As a result, if the style and size of the heater you are looking for is available in a certified version, it is highly recommended that you invest in this advanced combustion technology. You will help the environment and reduce your wood consumption by up to 30%.
NOTE: If you live in the United Sates, British Columbia, Ontario, Quebec, Nova Scotia, New Brunswick or Newfoundland, EPA certified wood heaters are mandatory. Exceptions apply for certain categories of products, such as decorative fireplaces. Certain municipalities may also have by-laws that require the installation of an EPA or CSAB415.1-10 wood heater, even though the province does not have an official regulation on wood heating. It must also be noted that in Canada, the CSAB415.1-10 Standard is equivalent to the EPA Standard. A wood heater that meets this Standard will generally comply with the regulation in place.
Why is the efficiency as per the EPA’s test data smaller than the publicized optimum efficiency?
EPA refers to the CSAB415.1-10 standard for the calculation of the appliance’s efficiency. The efficiency reported as per EPA’s directives consists of an average between four different burn rates, ranging from the lowest burn rate (air intake completely closed) to the highest burn rate (air intake completely open). The optimum efficiency that we publicize is the efficiency obtained according to the same test data, but for the low burn rate only. This efficiency is more realistic for a majority of users whose heating needs require that the unit be used to maximize burn times.
Why is the BTU according to EPA test data smaller than the one advertised?
You will notice a difference between the BTU output as per the EPA’s test data and what is advertised on our web site and/or product literature. The maximum BTU output we advertise 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 is 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’s test data is reduced. The BTU output that should be considered by a normal user is the one we advertise for seasoned cordwood.
Can I install an EPA or CSAB415.1-10 certified heater on an 8-inch chimney?
EPA or CSAB415.1-10 certified heaters function best on a 6-inch chimney (interior diameter). The problem with an 8-inch chimney is that the appliance may struggle to heat-up the air volume contained inside the chimney. A hot chimney is required to create enough draft. Poor draft will inevitably lead to poor combustion, which will cause smoke roll backs, a dirty glass, lack of heat, and a large quantity of unburned fuel inside the firebox. It is therefore highly recommended installing a 6-inch liner inside the 8-inch chimney. This liner may be rigid or flexible.
Is it recommended to keep the wood furnace's blower running continuously during winter in order to maintain a more even temperature throughout the house?
Indeed, installers often recommend this practice for oil, gas or electric central heating systems. However, it is definitely not recommended for a solid fuel fired furnace.
The heat generated by the wood furnace differs from other combustibles. As the wood load burns, the temperature varies lots based on the different stages of combustion. The temperature of the combustion gases must remain above the condensation point at all times in order to avoid the formation of creosote. The fan limit control will turn the blower off before the gases’ temperature drops under the condensation point.
In the case of a high efficiency furnace, stopping the blower will also help in keeping the firebox temperatures high enough for secondary combustion to take place. This is essential if you wish to have a clean burn and maximize the appliance’s efficiency.
Where on the hot air plenum of my wood furnace can I install the fan limit control?
The cold air forced through the furnace by the blower circulates around the firebox and is deflected towards the heat exchangers in order to transfer as much heat as possible. The hot air will then be distributed throughout the house.
The temperature inside the plenum will vary a lot from one spot to the other when the blower is running. The fan limit settings are determined in our factory such that the blower turns on when the temperature is sufficient to obtain the best heating efficiency and to turn off before the combustion gases cool down to the point where they could condense.
The proper position of the fan limit control is mentioned in all our manuals. The position of the fan limit control is of prime importance to insure the proper performance of the furnace.
Can I use my wood furnace during a power failure?
A wood furnace can be used in the case of a power failure without risking damaging the unit. The conception of the wood furnace is very similar to that of a wood stove. It is tested to withstand the intense heat of a wood fire, even if the distribution blower is not functioning due to the absence of electric current. The furnace’s efficiency will however be greatly reduced. Hot air will rise by gravity into the ductwork, but it will not be pushed into the rooms in an effective manner. In most installations, hot air circulating by gravity into the ductwork will be sufficient to keep the house warm enough to live in.
Should we install a barometric damper (draft regulator) on the exhaust pipe of a wood furnace?
In the case of older, conventional furnaces, the flame can easily reach the heat exchangers. When the installation or draft adjustment is inadequate, this tends to favor creosote build-up, which can be set on fire. Therefore, we recommend the installation of a barometric damper on this type of wood furnace.
For high efficiency furnaces (Mini-Caddy, Caddy, Max Caddy), the secondary combustion ensures that creosote is usually not a problem. The configuration of the firebox is such that the flame cannot travel to the heat exchangers. We do not supply any barometric damper with the furnaces for these reasons. However, a barometric damper is recommended in the case of excessive draft. Excessive draft occurs when combustion cannot be slowed down by closing the primary air inlet.
What will happen if there is a power outage and my wood furnace is in the middle of a combustion cycle?
A wood furnace can be used temporarily without electricity, taking into account the following guidelines:
Why does the electric unit overheat and trigger the manual reset thermodisc.
- The air filters are clogged or very dirty.
- The blower does not start (the first sequencer does not close or the motor is defective).
- The cold air return volume is not sufficient.
- There is excessive static pressure (the distribution duct is too small or there are not enough outlets).
- The heat sensor is defective (rare).
- The insulation between the cold air return cabinet and the air distribution cabinet is cut too short and restricts or diverts the air flow at the exit of the electric element, thus creating artificial overheat (rare).
Why can’t my Max Caddy heat my house when my old 150,000 BTU oil furnace could do it without any problem?
An oil-fired furnace will reach its maximum heat output within minutes of start-up and keep that pace as long as there is a call for heat. A wood furnace will generate its maximum heat output only at the peak of the combustion cycle. Before that, it needs to build a momentum. Then, the heat output will slowly diminish as the wood load gets consumed.
The performance of the wood furnace will also be affected by the quality of the combustible, which is not as constant and predictable as heating oil. It will vary a lot depending on the density and moisture content. Numerous other factors may also affect the performance of the furnace, such as a poor chimney draft, dirty heat exchangers, low static pressure, etc.
Can the Caddy add-on be installed with an existing propane or natural gas furnace?
The certification allows the installation with the two types of gas. Therefore, the Caddy add-on may be hooked-up with either a propane or natural gas furnace, provided that the gas unit’s output power does not exceed 35.17 kW (120,000 BTU/h).
Is it possible to reduce the fan speed of my PSG furnace to reduce the noise level?
Except for the Max Caddy and the Caddy Alterna, the blower motor on your furnace has four speeds and the installer will have to select two, that is one speed for continuous air circulation during the summer months (low) and one speed for heating. The latter will be selected in accordance with the ducts design and the air distribution needs (normally med-low or med-high).
Electrically speaking, the circulation and heating speeds may be the same if you connect both the black and red wires on the same terminal. You should however take note that reducing the heating speed will reduce the heat exchange and the furnace’s temperature will increase accordingly, which could cause the furnace to overheat.
Should you choose to reduce the blower speed, be certain that the primary air intake damper closes completely when the thermostat is not calling for heat so that in the case of an overheat, the damper motor being deactivated, the furnace will go into slow combustion and the blower will be capable of cooling it down.
Less air flow through the electric unit of a wood/electric combination furnace could also increase the risk that the overheat protection on the unit will trip. This is especially true if the air filter is dirty. This situation will leave you with no electric heat until the sensor is manually reset.
How do I determine what furnace I need between the Mini-Caddy, Caddy and Max Caddy?
We have a “rule of thumb” that is not scientific, but that can give you a good idea on what PSG product you need to install in your house.
We assume that the house has an average insulation, quality windows and doors and 8 foot ceilings, with a location in an area where winter temperatures are comparable to most Canadian areas. We do not count the basement. Start by calculating the area of the main floor and add 50% of the area of a second floor when applicable. If you do not exceed 1,000 square feet, the Mini-Caddy is adequate. Up to 1,700 square feet, a Caddy installed and operated as recommended should satisfy your heating needs. Above 1,700 square feet and up to 3,000 sq. feet, the Max Caddy should be used.
Of course, nothing can replace a heat loss calculation conducted by a forced air heating professional to determine your exact heating needs and verify your existing ducting for compatibility.
Can I add an air conditioning unit to my PSG wood-heating system?
My furnace is a wood electric combo. Is it possible to burn wood and run the fan with a generator in case of a power failure?
First, please note that your PSG furnace, if installed in accordance with the clearances, may be operated without the blower during a power outage, if authorized and mentioned in the manual. In such a case, it is recommended to open the blower access panel to help circulate hot air in the ducts by gravity. You also need to heat moderately. Note that the air intake damper motor will not work without power. It will need to be operated manually. It is possible to feed the blower with a generator, but you must make sure that the power from the house’s electrical panel is cut off to prevent conflict when the power is restored. This can be done automatically with the use of a suitable relay.
