This 4-way multi-positioning and modulating Category IV condensing
furnace is CSA design certified as a direct vent (2 pipes) or non-direct vent
(1 pipe). The furnace is factory shipped for use with natural gas. The
furnace can be converted in the field for use with propane gas when a
factory supplied conversion kit is used. Refer to the furnace rating plate for
conversion kit information.
This Category IV furnace is approved for installation in
Manufactured/Mobile housing.The furnace must be installed in accordance
with the instruction provided in this manual. A manufactured home
installation must conform with the Manufactured Home Construction and
Safety Standard, Title 24 CFR, Part 3280, or when this Standard is not
applicable, The Standard for Manufactured Home Installations
(Manufactured Home Sites, Communities and Set-Ups), ANSI/NCS
A225.1, and/or MH Series Mobile Homes, CAN/CSA-Z240. Follow all
national and local codes and standards in addition to these
instructions. The installation must comply with regulations of the serving
gas supplier, local building, heating, plumbing, and other codes.
This furnace is designed for minimum continuous return air temperature of
60 °F (16 °C) or intermittent operation down to 55 °F (13 °C) such as when
used with a night setback thermostat. Return air temperature must not
exceed 80 °F (27 °C). Failure to follow these return air temperature limits
may affect reliability of heat exchangers, motors, and controls (Figure 1
Freeze protection and return air temp.).
The furnace should be sized to provide 100 % of the design heating load
requirement plus any margin that occurs because of furnace model size
capacity increments. Heating load estimates can be made using approved
methods available from Air Conditioning Contractors of America (Manual
J); American Society of Heating, Refrigerating, and Air Conditioning
Engineers; or other approved engineering methods. Excessive over sizing
of the furnace could cause the furnace and/or vent to fail prematurely.

2.2- Electrostatic discharge
CAUTION
FURNACE RELIABILITY HAZARD
Failure to follow this caution may result in unit component damage.
Electrostatic discharge can affect electronic components. Take
precautions during furnace installation and servicing to protect the
furnace electronic control. Precautions will prevent electrostatic
discharges from personnel and hand tools which are held during the
procedure. These precautions will help to avoid exposing the control to
electrostatic discharge by putting the furnace, the control, and the
person at the same electrostatic potential.
1) Disconnect all power to the furnace. Multiple disconnectsmay be
required. DO NOT TOUCH THE CONTROL OR ANY WIRE
CONNECTED TO THE CONTROL PRIOR TO DISCHARGING
YOUR BODY’S ELECTROSTATIC CHARGE TO GROUND.
2) Firmly touch the clean, unpainted, metal surface of the furnace
chassis which is close to the control. Tools held in a person’s
hand during grounding will be satisfactorily discharged.
3) After touching the chassis, you may proceed to service the
control orconnecting wires as longas you donothing torecharge
your body with static electricity (for example; DO NOT move or
shuffle your feet, do not touch ungrounded objects, etc.).
4) If you touch ungrounded objects (and recharge your body with
static electricity), firmly touch a clean, unpainted metal surface of
the furnace again before touching control or wires.
5) Use this procedure for installed and uninstalled (ungrounded)
furnaces.
6) Before removing a new control from its container, discharge your
body’s electrostatic charge to ground to protect the control from
damage. If the control is to be installed in a furnace, follow items
1 through 4 before bringing the control or yourself in contact with
the furnace. Put all used and new controls into containers before
touching ungrounded objects.
7) An ESD service kit (available from commercial sources) may
also be used to prevent ESD damage.

3- ALIZÉ COOLING UNIT
To optimize your HVAC experience, Dettson offers a cooling system
called the Alizé.
3.1- Thermostat using Alizé system
When using the Alizé cooling unit, the communicating thermostat must
be used (R02P029). The interface card (K03069) will be able to gather
information from the outdoor unit, the furnace and the thermostat,
making this integrated system easy to install. The indoor blower speed
will be determined by various factors including outdoor temperature,
compressor speed and demand from the thermostat. The balance point
(temperature at which the unit will switch from heat pump heating to
auxiliary heat, in this case gas) will be adjustable through the thermostat.
If this unit is destined to be used as a cooling system only, the heat
pump can also be disable from the communicating thermostat, by using
emergency heat. For more details refer to the manual provided with the
thermostat.
3.2- Position of the interface board
Provision has been made on the main control board support in the
furnace to locate the interface board (K03069). Refer to Figure 4
Interface card position.
Figure 4 Interface card position
3.3- Wires connections with interface board
Figure 5 Interface board wires connection
Figure 5 Interface board wires connection, explains how to properly wire
the interface board to the ERV/HRV and main furnace control. For the
complete wire connection, please refer to the Alizé manual. The interface
board allows the ERV/HRV to be interlocked with the furnace, giving a
smooth and quiet operation of the whole system.

4- INSTALLATION
The furnace is factory built for upflow position. In this position, the drain
trap can be installed on right or left side depending on air return duct.
When installing the furnace in the upflow position, make sure it is
leveled.
To ensure proper drainage of the condensate when installed in
position other than upflow, tilt the furnace from level position to a
minimum slope of ½” higher at back to front.
When installing the furnace in other orientation than the upflow position,
simply configure the condensate tubing accordingly with the instructions
provided in this section of the manual.
CAUTION
PROPERTY DAMAGE HAZARD
Failure to follow this caution may result in water spillage and/or
property damage.
For any position other than upflow, the multiposition pressure
switch must be connected pneumatically to the condensate box
and electrically to the control to allow the furnace to stop in the
event of drain blockage.
Figure 6 Drain trap
4.1- Upflow orientation
In the upflow orientation, the drain trap (Figure 6 Drain trap) can
be installed to the right or to the left of the furnace. The
condensate drain hoses must be routed from the trap through the
furnace casing. Remove the knock out parts of metal and install
the hoses to the drain trap. The condensate hoses can be routed
through the left or right.
