About the VSL Boiler
The VSL Boiler is a Slant/Fin line indexed in the official library's 'Vintage' section: the hub breadcrumb prints 'Slant/Fin Library > Vintage > VSL Boiler' and the page carries no product copy and no status wording — only the document set. Section placement is the only official status signal, which Boilers.ca interprets as the archive signal for a line no longer in the current range.
The Vintage hub posts (all fetched 2026-09-09): VSL Installation Instructions and Maintenance Part A, Part B and Part C (513), VSL Parts List 611, VSL Dimensions 112, High-Efficiency Boiler Warranty 719, the shared VSL-160/VSL II 90-250 Energy Guide data (000465) and general notices including heat-exchanger and DHW cutaway images. Part C is the reachable discrete code table, printing L lock-out and E blocking codes; Boilers.ca does not wire error-code records for this line in this pass.
The hub prints no product copy or specification table, so Boilers.ca keeps the VSL at series level (hub-only pass, no model records) and does not assert a construction type or fuel beyond its gas taxonomy. The Energy Guide data document ties the VSL-160 to the VSL II 90-250 range in its title only; no per-model ratings were extracted. No official Canadian-sales statement exists, so canadianStatus stays 'unknown'.
