Secure Stack Pro at Emily Carr University

Check out the latest case study from Security Chimneys on the Secure Stack Pro installation at Emily Carr University. The Raven team worked with Northwest Sheet Metal, Pitt Meadows Plumbing, and Rocky Point Engineering. Completing the three 61-foot columns on the exterior of the University servicing three Blaauw gas-fired Kilns.

Running into changes throughout the project, all teams worked together to ensure we ended up with this beautiful end product. Bennett worked with Northwest Sheet Metal to find solutions to issues like how to support the venting along with lead times on extra pieces.

The Material

These Kilns need a speciality product for their high temperatures. Which is where Security Chimneys comes in with their factory fabricated grease duct. This project called for 304SS shells and fiber insulation. The venting is offered in many different materials depending on the application.

If you are looking for a vent material that can withstand temperatures of up to 1400°F and that is easy to install, there is no better option than Secure Stack Pro. Noel Robin at Northwest Sheet Metal says it reduced the manpower needed from upwards of 3 men into a one-man job. Not easy, especially with these heights.

Our Difference

Raven Supply specializes in complex venting systems offering many services that make us stand out from other suppliers. Including ordering extra pieces for difficult installations, site visits, detailed installation diagrams and having a knowledgeable team to help you size, select and design the best-engineered venting system for your application.

Emily Carr Case Study



The 2015 revision of CSA-B149 now permits common venting (aka “ CASCADE ”) with select condensing gas appliances.
Even so, there are important requirements that must be satisfied before an installation can proceed.

Potential pitfalls can occur if approved appliances are not paired up with an engineered vent system. Any short-cuts taken could result in non-compliant installations, impaired appliance performance, and compromised safety for building occupants. Let the experts at Raven assist with your design needs.

Vent sizing, pressure-drop, back-flow prevention, and condensation management are all serious considerations that must be factored into vent system design. Cascade venting systems should not be cobbled together using standard vent pipe or off-the-shelf fittings. Only specialized header components that have been specifically engineered for this purpose should be utilized.

If you are looking for assistance with commercial venting on a project in British Columbia or within the Yukon region, we can help. Our team at Raven Supply have specialized knowledge & experience in this area. Aside from determining suitability, we can provide design assistance, and deliver complete cascade venting packages for any commercial project – big or small.
