ACCESSORY CONNECTIONS
The furnace control will allow power-switching control of various accessories.
ELECTRONIC AIR CLEANER CONNECTION
Two 1/4” (6.4 mm) spade terminals (EAC and NEUTRAL) for electronic
air cleaner connections are located on the control board. The terminals
provide 115 VAC (1.0 amp maximum) during circulating blower
operation.
HUMIDIFIER CONNECTION
Two 1/4” (6.4 mm) spade terminals (HUM and NEUTRAL) for humidifier
connections are located on the control board. The terminals provide
115 VAC (1.0 amp maximum) during heating system operation.
A mounting hole is provided on the control panel next to the furnace
control board for mounting a humidifier transformer if required.
SINGLE STAGE THERMOSTAT
If a single stage thermostat is used for gas heating, the high/low input
staging will be controlled by the furnace control board using the staging
jumper. If the staging jumper is set to the 10, 15, or 20 position, the fur-
nace will switch from low fire to high fire after 10, 15, or 20 minutes and
will stay in high fire until the thermostat is satisfied. If the staging jumper
is left in the OFF position and a single stage thermostat is used, the fur-
nace will only operate at low fire.
TWINNING
These furnaces are not to be twinned. If more than one furnace is
needed in an application, each furnace must have its own complete
duct system and its own wall thermostat.
SECTION VI: CONDENSATE PIPING AND
FURNACE VENTING CONFIGURATION
CONDENSATE DRAIN LOCATION
As shipped from the factory:
•
For all 040, 060, & 080K input furnaces the main drain is plumbed
through the casing right-side opening when viewed from the front
of the furnace.
•
For all 100, 120, & 130K input furnaces the main drain is plumbed
through the casing left-side opening when viewed from the front
of the furnace.
The condensate hoses must slope downwards at all points.
When drain hose routing changes are required (shown in Figures 23-
26), be sure to cap all un-used openings.
If rerouting hoses - excess length should be cut off so that no sagging
loops will collect and hold condensate - which will cause the furnace to
not operate.
No hose clamps are needed for connecting to the condensate pan.

NOTICE
The Figures 23 - 26 show the condensate drain arrangement for the
various possible furnace and vent blower positions.
CAUTION
The furnace condensate pan is self priming and contains an internal
trap to prevent flue gas leaking. Do not install an external condensate
trap.
