CARBON MONOXIDE POISONING, FIRE AND EXPLOSION HAZARD.
Failure to follow this warning could result in death, personal injury and/or property
damage.
Do not operate the furnace with the rain cap removed as recirculation of the flue gases
may occur. Water may also collect inside the larger combustion air pipe and flow to the
burner enclosure.
6. Install the wye fitting and outer pipe assembly (Fig-5) through the structure’s
hole. For vertical termination, install the parts through the field supplied roof
boot/flashing.
NOTE:
Do not allow insulation or other materials to accumulate
inside the pipe assembly when installing through the structure’s hole.
7. Secure the assembly to the structure as shown in (Fig-2) or (Fig-3) using field
supplied metal strapping or equivalent material.
NOTE:
Ensure the termination height is above the roof surface or anticipated
snow level as shown in (Fig-2) for vertical termination. Ensure the termination
location clearance dimensions are as shown in (Fig-3) for horizontal termination.
8. Install the rain cap and the small diameter inner pipe assembly (Fig-6) in the wye
fitting and large outer pipe assembly (Fig-5). Ensure that the small diameter
inner pipe is bottomed out and securely cemented in the wye fitting.
9. Cement the furnace combustion air and vent pipes to the concentric vent
termination assembly. See (Fig-2) or (Fig-3) for proper pipe attachment.
10. Operate the furnace through one heat cycle to ensure combustion air and vent
pipes are properly connected to the concentric termination connections.
