Slant/Fin TR SERIES, models TRDV are approved for installation as a direct vent system. The following basic guidelines
should be observed according to the venting system in use.
In addition, it is strongly recommended that the applicable
precautions for Natural Draft Applications be used.
Installation Considerations
In addition to all the pertinent information regarding Natural
Draft Applications whenever a Mechanical Draft Application is
used it should be installed using the following instructions and
Figures 2 and 3 as reference.
• The terminating vent hood, and the inlet air hood are on
the same wall surface. and are on the wall opposite from
the prevailing wind wall, if possible.
• All of the air for combustion to the burner is supplied
directly from the outside of the building or structure.
• Not less than 12 in. above the total accumulated
snow and level grade.
• Not less than 4 ft. horizontally or below any
window, and door or air inlet and also not less than
1 ft. above any of these openings.
• Not less than 3 ft. above a powered air inlet
device that is within 10 ft.
• Not less than 2 ft. from any other building.
FIGURE 1: Slant/Fin model TRDV oil boiler with
vent kit
• At least 3 ft. from any inside corner of a building
• At least 1 ft. from any roof soffit or ridge vent.
• At least 7 ft. above any public walkway.
• All of the vent construction consists of suitable materials,
and terminates at an approved stainless steel hood.
• All of the vent piping must be sealed from air leaks.
• The vent pipe bend radius is 12 in.
• Brace metal strapping every 36 in. to support
vent pipe and prevent it from sagging.
• Follow the national codes for the installation of oil burning
equipment in USA-NFPA 31, in Canada CAN/CSA - B139
and local regulations.

Do not install vent terminals on prevailing wind wall side of structure.
Moisture and ice may form around terminal. Make sure the surface is in good
repair and protected from damage.
Slant/Fin models TRDV boilers can be installed on sealed or direct vented
systems. They must be ordered from the factory with an approved Direct Vent
System. Part numbers for the kits and accessories can be found on page 8 of
this manual.
NOTE: Vacuum Relief Valve (VRV) not shown. VRV must be located as shown
on page 8.

ADDITIONAL INSTALLATION CONSIDERATIONS (Figures 2 & 3)
1) Kit or system may vary based on specific needs of appliance.
2) Utilize the appliance adapter test port for combustion testing required by appliance manufacturers.
The vent terminal has a 0” clearance to combustibles
The insulator to vent pipe has 1” clearance to combustibles.

INSTALLING THE JOINT ASSEMBLY
1. Loosen the gear clamps attached to the adapter sleeve and
slide the adapter sleeve over the vent pipe, Figure 4 and
Figure 5.
2. Pull the corrugated inner tube out of the vent pipe for easy
access and insert the adapter.
3. Apply sealant around the corrugated end of the adapter.
4. Align the flat seams at the end of both corrugated tubes and
insert the adapter into the vent tube. Screw the adapter into
the vent pipe with a counter-clockwise motion. The adapter
should be fully inserted into the inner vent tube until it’s tight.
The seams of both tubes must be aligned for ease of insertion.
If the adapter does not completely screw into the vent pipe,
unscrew it and try again as per Step #4.
5. Seal around the edge of vent pipe inner tube.
6. Slide the adapter sleeve back onto adapter and tighten the
gear clamps to complete the connection.
7. If the vent requires cutting to length, a fine tooth hacksaw can
be used. Remove any burrs and flare out the end of the inner
vent tube for easy installation of the adapter.

INSTALLING THE OUTSIDE TERMINAL
The maximum wall thickness be no more than 14 in. Contact Slant/Fin for recommendation in
case of a thicker wall.
The system is not designed for common venting. Use for a single appliance only.
Use Figure 6 and Figure 7 to complete the following steps.
1. Determine the terminal location.
2. Cut 8-1/4in. diameter hole through the wall (slightly
larger than the O-D. of the terminal)
3. Pull apart the inner and outer terminal sections.
4. Slide the outer wall plate over the outer section of the terminal
until it rests against the bead.
5. From the outside of the building, insert the outer section
through the hole until it resets against the wall.
6. From the inside of the building, slide the inner wall plate over
the outer and secure using the (4) screws.
7. Position the outer section so the seam on the flue collar is on
the top and the air intake on the bottom. Secure the outer
section by tightening the gear clamp around it. The gear clamp
is factory welded to the inner wall plate.
8. Seal with a weather proof sealant around the bead and edge of
the outer wall plate to prevent water from getting inside.
