Oil-Fired Direct Vent Instructions
Vent Pipe Installation (
see Fig. 1-2
)
Vent Terminal Assembly
1. Determine proper location of the vent termina-
tion and cut an opening in the wall as follows:
– Combustible wall: 8 inches diameter.
– Non-combustible wall: 8 inches diameter.
2. Secure the trim plate flashing to the outside
wall.
3. Insert the terminal assembly through the trim
plate opening from the outside, until the stop
bead on the assembly is flush with the trim
plate.
4. Insert the inside trim plate over the terminal
assembly and secure it to the inside wall.
5. Tighten the band clamp on the inside trim plate,
securing the terminal assembly.
6. Seal around the outside trim plate and all exter-
nal joints with a weatherproof caulk.
Vent Pipe
1. Measure and cut the vent pipe to length. Use a
hack saw with a fine tooth blade.
2. Install the Terminal Connector and Appliance
Adapter to the vent pipe.
Note:
Insert the vent pipe through the Air Intake
Adapter prior to install the Terminal Connector
and the Appliance Adapter
– Apply a continuous bead of high tempera-
ture sealant around the outside of the corru-
gated pipe on the Appliance Adapter.
– Insert the adapter into the end of the vent
pipe using a twist motion. Turn the adapter
counter-clockwise until it is insert into the
vent pipe a minimum of 4 inches. The
outer collar of the adapter should overlap
the outside of the vent pipe.
– Tighten the band clamp on the outer collar
of the Appliance Adapter securing it on the
vent pipe.
– Repeat the above steps with the Vent
Connector.
Connecting the Appliance Adapter to the unit
1. Apply a continuous bead of high temperature
sealant to the inside of the Appliance Adapter
approximately 1/4” to 1/2” from the adapter
edge.
2. Slip the Appliance Adapter over the outlet of the
flue hood and tighten the band clamp.
DO NOT install a barometric damper. A baro-
metric damper is not required on direct vent
applications.
Terminal Connector to Terminal Assembly
1. Apply a continuous bead of high temperature
sealant on the inside of the Terminal Adapter
approximately 1/4” to 1/2” from the end.
2. Slip the adapter over the Terminal Assembly
until it is fully engaged. Tighten the band clamp
securing the adapter to the Terminal Assembly.
Air Inlet Adapter to Terminal Assembly
1. Apply a continuous bead of Silicone sealant
(high temperature sealant is not required) on the
inside of the Air Inlet Adapter approximately
1/4” to 1/2” from the adapter end.
2. Slip the Air Adapter over the Terminal
Assembly until it is fully engaged. Tighten the
band clamp securing the Air Inlet Adapter to the
Terminal Adapter.
3, Apply a continuous bead of silicone sealant
(high temperature sealant is not required) seal-
ing the gap around the vent pipe and the Air
Inlet Adapter.
Securing The Vent Pipe
•
Secure the vent pipe into position using strap
hangers.
•
Space the hangers appropriately to avoid any
sags or dips in the vent pipe. A maximum 5 feet
spacing is recommended.
•
Ensure all bends in the vent pipe are less than 90º.
•
All horizontal run must slope towards the vent
terminal at least 1/4 inch per foot.
