INSTALLATION –
Part 1
B
- Tailpipe Tubes
1.
Continue to install Hangers*, Tubes and Couplings as per Installation Part 1-A: Steps 1 to 3. Ensure that the
mounting height allows a downward slope of ¼” per 10 ft (7 mm per 3 m) towards the Vacuum Pump
location.
*On Tubes which will NOT have Reflectors, i.e. Tailpipe, the use of Hanger Straps instead of Reflector
Hangers is approved.
2.
BEFORE installing the Tee Section between the Branch Tailpipes and the Common Tailpipe determine
where the Damper Couplings need to be installed.
3.
Check which type of System is being installed, Symmetric (
S
) or Non-Symmetric (
N
) as per Figure 1 and
Figure 2. Dampers are positioned to allow the Vacuum Setting at the Branch End Vent to be adjusted
individually for each Branch. Symmetric / Identical Branches require the same Vacuum setting so One
Damper coupling is located before the Tailpipe splits into separate Branches. Non-Symmetric Branches
require a separate Damper Coupling for each Branch. For Modulating Rate Systems ensure that Motorized
Damper Couplings are used.
Damper Couplings are ONLY installed in the locations on the System where the respective letter reference
“S”,
OR
“N”
is located in Figure 15, on all other connections use normal Couplings. Dampers and
Couplings are installed using the same method. (See previous section.)
4.
Continue to install the Common Tailpipe in the same manner as all other Tubing. Ensure that the mounting
height allows a downward slope of ¼” per 10 ft (7 mm per 3 m) towards the Vacuum Pump location.
System is now ready for Vacuum Pump and Ventilation connection(s).
