GOLD GV Series 3 & 4 — Z-Vent II Venting Supplement
Installation — assembly
Connect vent starter tee to boiler
Follow the instructions in the GV Boiler Manual to connect the vent starter tee to the boiler.
Construct vent and optional combustion air run
Follow vent pipe manufacturer's instructions for sealing the vent. Vent and
combustion air connector piping must be sealed gas-tight to prevent
possibility of flue gas spillage and carbon monoxide emissions, resulting in
severe personal injury or death.
1. Follow Z-Vent II manufacturer's instructions to construct vent run and for methods of
supporting vent runs.
• Clean joints before sealing. See vent pipe manufacturer's instructions to clean joints.
• Use their specified sealant (maximum 250 °F flue temperature). Do not use screws.
• Do not mix types or manufacturers of vent materials.
• Maintain minimum one-inch clearance from combustible materials to vent pipe; 0"
clearance for noncombustible materials.
• Install vent pipe with seams on top of vent runs.
• If needed, male end of vent pipe may be cut to provide correct length. See vent pipe
manufacturer's instructions for use.
2. If installing with direct vent through sidewall method, use instructions provided with
Weil-McLain Vent/Air Intake Termination Kit. See Figure 3 on page 5.
Connect vent run to termination
Venting through sidewall
1. If using Weil-McLain Vent/Air Intake Termination Kit, see instructions provided in that
kit. Applies to direct (Figure 3, page 5) or non-direct vent (Figure 4, page 5) method.
2. If using non-direct method with termination coupling only, see Figures 8 and 9.
• If passing through noncombustible wall, provide hole diameter large enough to insert
the slip connector through. Sleeve and spacers are not required.
3. Maintain minimum one-inch clearance from combustible materials to vent pipe; 0"
clearance for noncombustible materials.
4. Refer to vent termination WARNING, item 19 on page 3.
Venting through existing chimney or roof
1. Direct vent method — follow instructions supplied in Weil-McLain Through-Roof or
Through-Unused-Chimney Termination Kit to assemble termination.
2. Non-Direct vent method (only through the roof, not through chimney):
• Vent pipe must extend through roof flashing, jacket or thimble. See Figure 10.
• Vent may pass through floor, inside wall or concealed space when installed according
to vent pipe manufacturer's instructions.
2. Maintain minimum one-inch clearance from combustible materials to vent pipe.
