EFFICIENCY
Always leave burner set with CO
2
reading about 1% lower than the peak CO
2
efficiency achieved with a zero to trace smoke (e.g. a zero to trace reading of
12.5% CO
2
should be set back 1% to 11.5%). This gives better allowance for
fuel and draft variations and maintains a better seasonal efficiency. When the
burner is set, lock the adjustments with locking nuts. Always set flame with
proper draft, smoke and CO
2
measurements.

2.10 CLASSIC AIR BLOWER SETTINGS
Ensure power is off when adjusting blower setting
. For heating, use the blower speeds
shown on the furnace specifications to give a rise of 70 - 85°F. The #4 Lo blower speed can
be used for air circulation when either heating or cooling are not required. Set blower speeds
to match the installation requirements.
2.11 AIR CONDITIONING
IMPORTANT
–
MAX/EVO
models that make use of the Auxiliary Sensor for better
dehumidification MUST have a Thermal Expansion (TX) Valve incorporated into the A/C piping
system. Most evaporator manufacturers 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. The firing rate of 157,000 Btu/h, on the
Classic
Air
,
EVO
or
MAX
, cannot be used in conjunction with an air conditioning coil.
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.
