INSTALLATION OF HORIZONTAL SUPPORTS
IMPORTANT: The vent system MUST be supported
DURING THE POINT OF INSTALL.
Example:
1) From your selected termination point at the wall you
can prepare your support locations by temporarily
placing one end of a straight length of wood such as
a 2” x 2” or 2” x 4” or broom handle in the prepared
termination location.
2) Lower the other end of this length of wood to make
certain that you have sloped / pitched your horizontal
run properly. (minimum ¼” per foot slope)
3) Affix your hanger supports at the proper intervals. I.E.
At each “directional change” and every 48 inches
4) Install pipe and or fittings through the supports during
assembly.
VERTICAL VENTING INSTALLATION
¾ Single wall vent terminations above the roof line must be at least 3 ft. (.9m) high to a maximum of 6 ft. (1.8m) without the
use of lateral supports and 2 ft. (.61 m) higher than any part of a structure within 10 ft. (3.1 m).
¾ Each pipe joint above the roof shall be connected using the coupling / guy band assembly.
¾ Vertical heights greater than 6ft. above the roof shall have guy wires connected to the coupling / guy band assembly at 6 ft
intervals. Fasten Guy wires of stainless steel or galvanized cable with a minimum capacity of 500 lbs. to each of the four
anchor holes that is integral to the coupling / guy band assembly and anchor to the roof structure using the appropriate
fastening method.
¾ The total vertical distance of the vent system from appliance flue collar to the rain cap termination and the maximum
length of offsets shall not exceed that specified in the appliance manufacturer’s installation instructions.
¾ All horizontal sections must observe the rules for HORIZONTAL VENTING.
1. Prior to beginning the installation, loosely assemble all parts required to make sure all parts are present.
2. Review the venting requirements section in the appliance manufacturer’s installation & operating manual to determine the vent
system configuration.
3. Select and apply the appliance adaptor to the flue outlet collar of the appliance.
4. Locate and mark the breach location(s) of the vertical stack for Fire-stop Support(s) and/or Fire-stop Spacer(s) and Roof Jack
Support. Refer to sections:
i) INSTALLING FIRE-STOP SUPPORT / SPACER
ii) INSTALLING Z-VENT ROOF JACK SUPPORT SYSTEM
5. Install the required Fire-stop Support(s) and/or Fire-stop Spacers and Roof Jack Support per the instruction listed above.
6. Continue connecting the required lengths of pipe and fittings starting from the appliance adaptor throughout the system
making certain to follow the instructions in this guide with respect to i) Clearances ii) Joint Procedure, ii) Slope iii) Drain Traps
iv) Supports and vi) Vertical Termination.
7. Where a pipe is to install through a Fire-stop Support. Insert small end of pipe through loosely connected clamp and insert
into gasket end of mating pipe. Position properly and, if necessary maintain proper horizontal slope and tighten the two nut &
bolt assemblies to the plate.
8. Where the vertical system is to install through the Z-Vent Roof Jack Support System refer to the section
INSTALLING Z-VENT ROOF JACK SUPPORT SYSTEM
9. Repeat step 6.
