Metal-fab MF-5DVS Direct Vent Vinyl Siding Stand Off

Product Description

The METAL-FAB MF-5DVS is a direct vent vinyl siding stand off designed to provide proper clearance and support where direct vent termination pipes pass through or terminate at vinyl-clad exterior walls. It creates a stable mounting point that protects the siding surface from heat and contact damage while keeping the vent termination positioned correctly relative to the wall plane. HVAC technicians and gas appliance installers use this fitting during new installations and replacement service on direct vent heating equipment.

This stand off is suited for residential and light commercial applications where direct vent gas appliances terminate through vinyl siding. It is used at the exterior wall penetration point to maintain proper standoff distance between the vent fitting and the siding surface, preventing warping, melting, or contact damage to the vinyl. It is typically installed alongside direct vent wall terminals on furnaces, boilers, and water heaters that use concentric or two-pipe direct vent systems.

Key Features

• Designed specifically for vinyl siding exterior wall applications
• Provides correct standoff clearance between vent termination and siding surface
• Protects vinyl siding from heat and mechanical contact at vent penetration points
• Compatible with direct vent concentric and two-pipe termination systems

Compatibility

Designed as an OEM-style accessory for direct vent gas appliance termination systems installed through vinyl siding on residential and light commercial structures.

Installation Notes

Installation is performed by licensed HVAC technicians or gas appliance installers following local mechanical codes and manufacturer venting instructions. Shut off the gas supply and disconnect power to the appliance before beginning any vent termination work. Ensure wall penetration sizing and placement comply with the appliance manufacturer specifications and applicable codes such as the IFGC. Do not compress or distort the stand off during installation, as proper standoff geometry is critical to maintaining required clearances.
