2.11 AIR CONDITIONING
An air conditioning coil may be installed on the supply side only. Coils installed on the return
side will cause condensation on the heat exchanger; this will shorten the heat exchanger life
and may cause products of combustion to enter the house. The bottom of the drain pan must
be at least 10” above the top of the heat exchanger. Wire as per Figure
– 4.
Height of the
coil above the heat exchanger shall be no less than 10” (254 mm).
*See A/C coil Manufacturers Requirements
CLASSIC AIR MODELS
Air conditioning models include a fan centre relay wired to run the blower at #1 Hi speed when
the cooling cycle is operating. For normal operation, select “AUTO” on the thermostat. When
“FAN ON” is selected the blower runs constantly at the cooling speed. See section
2.16
CLASSIC AIR OFF CYCLE AIR CIRCULATION
. For air conditioning, the blower on #1 speed
will provide 1200 CFM at 0.50 in. wc static pressure.
MAX/EVO MODELS
IMPORTANT
–
MAX/EVO
models that make use of the AC/auxiliary Sensor for better
dehumidification MUST have a Thermal Expansion (TX) Valve incorporated into the A/C piping
system. Most evaporator manufactures have the option of supplying the thermal expansion
valve built right in to the evaporator. If there is not a thermal expansion valve on the evaporator
then a thermal expansion valve kit MUST be properly installed in the evaporator system to
ensure proper operation of the A/C system.
2.12 HUMIDIFIER
If a humidifier is installed ensure that no water can drip or run from it into the furnace. This
would cause deterioration and void the furnace warranty.
2.13 THERMOSTAT ANTICIPATOR SETTING
The thermostat anticipator setting is only applicable to the non-electronic type of thermostat.
Electronic thermostats do not have an anticipator setting. All
Classic Air
burners use 0.2
amps. The
MAX/EVO
control requires 0.1 amps as a thermostat anticipator setting. Check
that the thermostat anticipator setting matches the primary control circuit current draw. This
setting affects the thermostat’s response to the control.
2.14 BLOCKED VENT SWITCH
Furnaces installed on a chimney (i.e. not Direct Vent or Power Vent) require a blocked vent
shut-off system when installed in Canada. A safety switch is included with the furnace to
perform this function. It is the installer’s responsibility to install the switch in accordance with
the instructions provided.
