CARBONMONOXIDE POISONING HAZARD
Failure to follow the instructions outlined in Locating
the Vent Termination for each appliance being placed
into operation could result in carbon monoxide poison-
ing or death.
The instructions included with this furnace DO NOT
APPLY to vent systems that are located below the fur-
nace. CAREFULLY FOLLOW THE INSTRUCTIONS
PROVIDED WITH THE EXTERNAL VENT TRAP KIT

Proper configuration of the venting and drain system is
critical when placing all or part of the venting system
below the level of the furnace. VENT GASSES
COULD BE RELEASED FROM THE DRAINAGE
SYSTEM, if the instructions provided with the External
Vent Trap Kit are not followed.
