Furnace PVC intake piping reconfigured to sit well above the deck surface at a Vaughan home, after the red tag correction

Fixing an Intake Clearance Red Tag in Vaughan

A Vaughan homeowner called us after their furnace was red tagged. The reason was the fresh-air intake piping outside the house. Its termination had been installed too close to the exterior deck, so it didn’t have the clearance it needs above the deck surface. We reworked the PVC intake piping to fix that.

The Problem

Why the Furnace Was Red Tagged

This red tag was about clearance. The furnace draws its fresh air through PVC intake piping that ends outside the house, and that termination needs a required clearance above the deck surface. Here it had been installed too close to the deck to meet it.

The Fix

Raising the Intake Above the Deck

The photo here shows the original setup, with the piping running along the deck. We modified and reconfigured the PVC intake piping so it now rises up the wall and ends at the proper height above the deck surface. You can see the finished result in the first photo on this page.

Project summary: a furnace red tag correction in Vaughan, Ontario, completed in October 2026. The fresh-air intake termination sat too close to an exterior deck, and we reconfigured the PVC intake piping to give it the required clearance above the deck surface.
