WARNING: If not attached to an appliance's air intake, the opening in the Air Intake Tee must
be kept uncovered and unobstructed to prevent the risk of fire.
Air Intake Connections for Direct Vent and Sealed Combustion Appliances*:
Insert the male end of the Air Intake Tee into the female end of the EZ Seal vent section or
appliance adapter and complete the ring and tab connection.
Insert the male end of the next SC section into the female end of the Air Intake Tee and

WARNING: This application must be approved by the Appliance Manufacturer.
The Air Intake Tee may be used on approved direct vent and sealed combustion appliances
that have separate (non-concentric) air intake and flue exhaust collars. The male end of the
tee connects to EZ Seal appliance adapters and the tee takeoff /snout connects to the
appliance air intake.
Install the appliance adapter onto the appliance outlet, placing the end with the snap ring away from the
appliance. Secure the adapter onto the outlet collar using the three self-tapping screws provided. Follow
the SC joint assembly instructions.
Saf-T Vent SC Air Intake System

* Direct Vent Appliances are constructed and installed so that all air for combustion is supplied
directly from the outside atmosphere. The passage for the combustion air is allowed a small
amount of leakage in the building environment. No special installation considerations are required
to use Saf-T Vent SC on Direct Vent appliances unless specified by the appliance manufacturer.
Sealed Combustion appliances are similar to Direct Vent except the combustion air passage
must be sealed to prevent leakage within the building envelope. When Saf-T Vent SC is used
on approved Sealed Combustion appliances the joints of the outer jacket must be sealed with
a foil tape (example: 3M 425), or approved silicone sealant (example: Dow Corning 732).
