12- 100% pilot light: indicate that the chosen heating capacity is 100%.

Continuous ventilation modes

Thanks to your SEFE furnace, it is possible to continuously ventilate your house. The control panel included two continuous ventilation speeds (low and high).

Low speed continuous ventilation

Use low speed continuous ventilation all year for maximal comfort due to constant air temperature. If your central heating system is equipped with an efcient lter

and you use the low speed continuous ventilation all year long, the air in your house will be healthier as it will be permanently ltered. Continuous ventilation will

also have a positive effect on air humidication if your system includes a humidier.

High speed continuous ventilation

If you do not have an air-conditioner, the high speed continuous ventilation mode is perfect during hot sunny days. In this mode, the furnace blower provides a

powerful airow that quickly circulates throughout the house.

If a continuous ventilation mode is activated when there is a heating demand, it is temporarily deactivated to allow the blower to switch in heating speed. The pilot

light indicating the selected continuous ventilation mode will however remain on to indicate that the continuous ventilation will start again at the selected speed

once the heating demand will be completed.

Continuous heating modes

Air temperature variations in your house have a huge impact on your comfort. The SEFE furnace propose a continuous heating mode minimizing temperature

variations between heating demands from the thermostat.

If you feel uncomfortable temperature variations when it is cold outside, activate the 2.5 kw continuous heating mode. For more power, simply activate the 5 kw

continuous heating mode.

Note that if you choose to activate the continuous heating mode, the low speed continuous ventilation will automatically be activated. It is also possible to select

the high speed continuous ventilation when the continuous heating mode is activated.

The continuous heating mode become automatically in stand-by at the end of the heating season and it is automatically reactivated at the beginning of the next

heating season. Consequently, you do not have to deactivate this mode in summer. When in stand-by, the LED pilot light indicating the selected continuous heat-

ing mode (2.5 kw or 5 kw) will blink. You can deactivate it at any time by pressing on the button corresponding to the activated mode (2.5 kw or 5 kw).

Heating capacity selection (50% or 100%)

At the beginning and the end of the heating season, the weather is more gentle than at the heart of winter. So, your house may not require the full capacity of your

SEFE furnace. That is why the control panel include a button that enables you to choose between 50% or 100% capacity.

In spring and fall, select the 50% capacity mode to reduce the heating power by about the half when there is a heating demand from the thermostat. This will

increase your comfort while allowing you to make energy savings.

In the middle of the heating season, it is recommended to select the 100% capacity mode.

N.B. If the furnace is connected to a two-stage thermostat, the furnace heating capacity must always be set at 50%. If not, you will not enjoy the

benets of this type of thermostat.

MAINTENANCE

N.B. In order for the warranty to be valid, the unit must be cleaned regularly. Moreover, a qualied technician must examine your furnace on

a regular basis.

Cut off power supply at circuit breaker/fuse before cleaning the unit. Use a soft rag for dusting. When cleaning, use only a damp rag and non-abrasive dish soap.

Do not use abrasive or chemical cleaners because they can damage the nishing. If the unit is used in a very dusty location, use a vacuum brush to remove dust

and other foreign objects.

N.B. Note that there is electrical current to the unit even if the thermostat is off. Meaning that there is a risk of electric shock as long as the unit

is energized.

Preventive maintenance

Do not try to repair your furnace yourself. Call a qualied technician. However, before calling a technician, check the following points:

1) Make sure fuses or circuit breakers are activated;

2) Adjust the temperature set point of the thermostat above the ambient temperature. If heating does not start, cut off the power supply and call a technician.

N.B. When calling a technician for maintenance or to order a replacement part, specify the model of your furnace as well as its serial number.

Air lter

Excessive dust or dirt accumulation can block the airow, forcing the unit to work harder to maintain the desired temperature. Therefore, it uses more energy and

increases heating costs.

Since the air lter supplied is disposable, you should replace it two to four times a year, according to the model used and the installation area. Dirtier areas can

require more than four lter changes.

To replace a dirty lter, open the access door to the lter, remove the old lter and insert the new one inside the rack. Make sure the new lter has the same techni-

cal specications and size as the previous one.

N.B. Never operate the unit without a lter in place.

Every time a lter is changed, you should check the following points.

- Excessive accumulation of dirt or dust on furnace components.

- Damaged components or surfaces.

- Presence of water inside or outside the furnace.

If you encounter any of these problems, do not operate the furnace. Call a qualied technician.

Blower

The blower motor is sealed and permanently lubricated, so it is not necessary to lubricate it.

Even if you change the lter frequently, the blower’s blades and motors will become dust laden after a few months. The entire blower assembly should be

inspected annually. If needed, vacuum out the dust. If you cannot clean the blower without removing it from the furnace, this service must be performed by a

qualied technician.

TROUBLESHOOTING

If you encounter a problem, check the following table before calling a technician. Should modication or servicing be required, make sure the technician uses only

factory authorized parts, accessories, or kits for this furnace.
