Simplicity, Versatility, and Heat Output
Distinct by its clean lines and renewed style, the Caddy Alterna is a 120,000 BTU/h hot air pellet furnace. This pellet furnace can also be a combined pellet-electric and is tested according to the CSA B415 1-10 Standard. This unit is an environmentally responsible heating option even in Canada’s harshest winters. At the cutting edge of technology, it has one of the latest technology LCD control panel that lets you program the furnace rapidly and easily. Its PC board allows 3 additional input configurations: 60,000 BTU/h, 80,000 BTU/h, and 100,000 BTU/h. In terms of heating capacity, it is important to consider the benefits of the regulated feed rate provided by a pellet furnace like the Caddy Alterna. The heating output can also be regulated by the owner to accommodate his needs. This flexibility will therefore, extend the unit's cycling intervals, leading to substantial fuel savings.
- A respectable 240 pounds hopper capacity, that offers considerable heating autonomy;
- A combustion chamber bottom feed system allows the burn pot to stay clean;
- An optional electric element can be installed on either side of the furnace offering alternative heating in case of lack of pellets;
- Superior quality components from leading brands and whose maintenance is minimal and;
- An optional hot water loop kit to preheat domestic water.
With the Caddy series furnaces you will never again be dependent on a single source of energy to guarantee the comfort and safety of your family. The Caddy Alterna allows 2 different configurations: pellet only or combined pellet+electric.
This wood and biomass pellet furnace can be installed as a pellet only unit.
Combined Pellets + Electric
This furnace can be installed as a pellet+electric combination to avoid interruption of your central heating when you are not available to feed the wood or biomass pellets. The addition of an electric element is required for this type of installation.

Why do I get moisture in the hopper of my pellet heater?
Moisture can form on the inside of your hopper due to cold outside air entering your unit through the exhaust vent when the unit is not being used. Cold outside air condense when it becomes in contact with room air. This occurs when there is a negative pressure in the room where the unit is installed. To correct this problem, the room needs to be balanced by either directly connecting outside combustion air to the unit or to the room where the unit is installed.
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.
Will the Caddy Alterna restart after a power failure?
After a power failure, your pellet furnace will not restart automatically. However, if your system is combined with an electrical element, as soon as the power returns, your electric element will take over. It will then be possible to restart the pellet system by pressing the START button.
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.
Can I vent my pellet appliance using my existing prefabricated chimney?
Can I use a GFCI receptacle on my pellet appliance?
This is not recommended. The GFCI will sense the difference in the amount of electricity flowing in and out of the circuit, even in amounts of current as small as 4 or 5 milliamps. The GFCI reacts quickly (less than one-tenth of a second) to trip or shut off the circuit.
A properly grounded 3 prong outlet provides adequate protection for both people and the appliance should a short circuit occur.
