STARTUP PROCEDURES

This furnace is equipped with a HSI (Hot Surface Ignition) device. Each time that the room thermostat calls for
heat, the HSI lights the main burners directly. See the lighting instructions on the furnace.
NOTE
It is recommended that the drain trap assembly be primed before the initial startup. Refer to the
instructions on how to prime the condensate trap on the previous pages in this manual. A dry
trap will allow fl ue gases to fl ow through the recovery coil drain, which will prevent the condensate
from draining from the recovery coil. If enough condensate accumulates in the recovery coil,
the recovery coil pressure switch will sense this condition and break its electrical contacts, and
extinguish combustion. If this takes place, the induced blower will stop after a brief post-purge
cycle, the condensate will drain out and fi ll the trap. If the thermostat is still calling for heat, the
ignition sequence will start again after a 5 minute wait.
