Vertical (Through Roof) Venting
This kit uses either Simpson Duravent GS direct vent pipe, Secure Vent direct vent pipe or Selkirk Direct-
temp vent pipe with a 5” inner pipe and an 8” outer pipe. For part numbers see the table of venting
components on page 11 of this manual.
Vertical installations must use the optional TCVT.PVVCA vertical adaptor box in conjunction with this kit.
The vertical
adaptor box can only be installed on a flat surface. Sloped surfaces require the construction of a chase which provides the
minimum interior, square opening of 11” x 11” for the venting and wiring to pass through. Flat roofs may require a chase
depending on local codes and roof construction. (If in doubt check with local inspector)
The terminal must be located in accordance with the clearances outlined in Fig. #1 and 2.
All part numbers in the following section are shown in Fig.
#5.
1. Place the flashing (Part A) onto the chase and seal
using silicone.
2. Put a bead of silicone on the underside of the vertical
standoff (Part B) and place it on top of the flashing. Align
the eight holes and secure both parts to the chase using
eight #8 x 1 1/2” screws provided.
3. Install the drip shield (Part C) onto the top of the vertical
standoff using a bead of silicone between the two. Do not
screw this part in place.
4. Bring the 14-2 electrical wire (not supplied) up through
the holes in both the flashing and the drip shield leaving at
least 12” of excess wire above the drip shield.
5. IMPORTANT: Attach an appropriate length(s) of the
vent to the power vent terminal, sufficient to pass through
the chase.
NOTE: DO NOT CONNECT AN ADJUSTABLE LENGTH
VENT PIPE TO THE TERMINAL.
6. Seal the connection of the first length of pipe at the
terminal and any other pipe to pipe joint by both screwing
and taping the outside joint using high temperature foil
tape.
7. Remove the junction box cover. (Part D)
8. Remove and discard the exhaust shield. (Part E)
9. Apply a bead of silicone on the bottom flange of the
power vent terminal (TCVT.WSPVB1)
10. Slide the vent through the drip shield and at the same
time thread the electrical lead through the hole in the
bottom of the terminal.
11. With the power vent terminal resting on the drip shield,
align the eight holes in each of the vertical standoff, the
drip shield and the power vent terminal and then screw
them together using the eight #8 x 1/2” stainless screws
provided.
12. Join the 14-2 wire lead to the blower wires using
the appropriate connectors and attach the ground wire.
Reinstall the junction box cover.
13. Install the vertical rain cap (Part F) over the power vent
blower. ALIGN THE EXHAUST OUTLET ON THE POWER
VENT TERMINAL WITH THE EXHAUST PORT ON THE
VERTICAL RAIN CAP.
14. Secure the vertical rain cap to the power vent blower
with the remaining eight #8 x 1/2” stainless screws.
NOTE:
THERE ARE NO PILOT HOES IN THE BASE OF THE
POWER VENT TERMINAL. 1/8” DIAMETER PILOT
HOLES SHOULD BE DRILLED USING THE HOLES IN
THE VERTICAL RAIN CAP AS A GUIDE.
DO NOT SILICONE THE VERTICAL RAIN CAP TO
THE POWER VENT TERMINAL AS IT NEEDS TO BE
REMOVABLE FOR SERVICING.
15. Attach the vent adaptor directly to the appliance with
three screws provided. (Fig. #4)
16. Connect the high temperature silicone tube to the
pressure tap on the adaptor, secure with the hose clamp
provided and route the tube through any hole back to
control box. (Fig. #4) Tube may touch unit and be trimmed
if required.
Note: Ensure that there are no blockages in
this tube, as this will cause the control to malfunction.
17. Run the required Simpson Duravent GS / Secure Vent
/ Selkirk Direct-temp pipe from the adaptor to the terminal
assembly. Assemble as per the vent pipe manufacturer’s
instructions.
Installation:
CAUTION: The vent restrictor must be fully
open for proper operation.
