HTP Flexible Vent Kit - Manual (Page 4)

4
• Common venting of more than one appliance is not allowed.
• No other gas-burning appliance may be vented in the same chase/chimney with the flexible vent
system.
• The maximum length, correct diameter, and number of fittings must be in conformance with the
specifications of the appliance manufacturer’s instructions.
• The venting systems must be installed with correct distance to combustibles.
• Check for proper joint construction.
Additional instructions for termination:
• The vent system must terminate at least 2’ (0.6 m) above the roof line or any wall or vertical
structure within 10’ (3 m).
• Do not install an extra rain cap on the terminal. The terminals are specially designed for high
efficiency boilers which produce large quantities of moisture due to condensation of combustion
gases. This design allows rain to enter the terminals which also serves to dilute acidic
condensate.
• Follow the specific mounting instructions at the end of this manual.
E. INSTALLATION
Special notes:
• The flexible liner must be treated carefully at low temperatures (<5 o
C) (<41
o
F).
• Check all parts for possible shipping damage.
• Rotate the components slightly to assist assembly.
Installation procedure for flexible flue liners:
1. Determine the required location of the opening in the shaft. Ensure the flue access cut-out meets the
minimum specified size to allow manual assembly of connections within the flue. The slope of the
connecting flue pipe must have a minimum of 3
o
(equivalent 1.9”/ft.) (5cm/m).
2. Fix the elbow support bracket (Fig. 1) with 4 screws on the wall of the
chimney or chase.
3. The length of the flexible liner can be determined in two ways: 1) Use a
rope with a small weight on the end to measure shaft length. Add 16
inches (.4 m) extra length for each bend. The flexible liner can be
shortened with a saw or scissors by cutting in a groove. 2) Correct liner
length can also be determined after installing the liner in the shaft and
cutting it as the top of the chimney or chase (see Fig. 10, Dimension B).
4. When required, a coupling (Fig. 2) can also be used to connect two lengths of
flexible liner together. This piece can be ordered as an accessory (Part #8400P-
005).
5. Mount the seal into the lowest whole
groove (Fig. 3) and push the flexible liner into the adapter until it stops.
