PRIMING CONDENSATE TRAP

IOM
IOM IMPORTANT:
THE CONDENSATE DRAIN TRAP ASSEMBLY SHOULD BE FULL OF WATER (PRIMED)
BEFORE STARTING THE FURNACE. TO FILL THE CONDENSATE DRAIN TRAP ASSEMBLY,
TEMPORARILY REMOVE THE VENT DRAIN HOSE FROM THE EXHAUSTER ASSEMBLY
ELBOW/DRAIN FITTING, AND POUR APPROXIMATELY ONE CUP OF WATER DOWN THE
HOSE. WATER WILL BEGIN RUNNING OUT THE CONDENSATE DRAIN TRAP OUTLET
WHEN IT IS FULL. REFASTEN THE VENT DRAIN HOSE TO THE EXHAUSTER ASSEMBLY
ELBOW/DRAIN FITTING.
THE CONDENSATE DRAINAGE CONFIGURATION REQUIRES A VENT. IT TAKES LESS
THAN A ONE INCH RISE ANYWHERE ALONG THE HORIZONTAL ROUTE OF THE DRAIN
TUBE TO CREATE A VAPOR LOCK, WHICH WILL PREVENT CONDENSATE FROM
DRAINING AWAY FREELY, AND RESULT IN ERRATIC FURNACE OPERATION.
