Prepare the Furnace Internal Trap
These instructions MUST be followed in order to provide for safe
operation of the furnace.
1. Position the furnace in its final operating orientation.
2. Configure the internal furnace drain trap as shown in the furnace
installation instructions for that orientation.
3. Once the drain trap configuration is complete as described in the
furnace installation instructions, remove the internal furnace drain
trap and install the Internal Drain Trap Plug as shown in
FOR THAT ORIENTATION. Re-install the furnace drain trap.
4. Complete DRY FIT assembly of the field-supplied drainage system
drain lines as shown in the appropriate
, and as
directed in the furnace installation instructions.
5. IF ALLOWED BY LOCAL CODE, it is recommended that a short
piece (6-in./15 cm) of clear tubing be applied near the exit of each
trap to allow observation of correct drain trap operation.
6. DO NOT cement drain lines at this time. See Drainage System
Layout and Installation section.

WARNING
!
CARBON MONOXIDE POISONING
Failure to follow these warnings could result in personal injury or
death.
The internal drain trap plug MUST BE APPLIED to the vent side of the
collector box trap connection of the furnace. Failure to do this may
result in vent gases being released into the living space.
Failure to use a properly constructed trap(s) or NOT water-priming
trap(s) before operating furnace may allow positive pressure vent gases
to enter the structure through drain tube. Vent gases contain carbon
monoxide which is tasteless and odorless.
