The DCC (combi) and DCB (central heating) wall-hung AI condensing boilers are Dunkirk's '(While supplies last)' line: the official page prints that badge under the product title with zero current documents, all literature archived. The seven models — DCC-115/150/205 combis and DCB-75/100/125/165 heating-only — share the ECR AI platform also sold as Utica's MAC/MAH.
Series facts
95% AFUE as printed for every model in the official DCC/DCB sell sheet table except the DCB-75, which prints 92% (same anomaly as Utica's MAH-75).
The DCC/DCB family is the Dunkirk-branded version of the ECR International 'AI' wall-hung condensing platform — the same models and same manual print (PN 240013687, MGC-2209-REV-A) as Utica's MAC/MAH boilers. The official DCC page covers the combi and central-heating models together: DCC-115/150/205 combis (CH input 93.5/125/164 MBH maximum, DHW to 115.5/153/205 MBH at 2.5/3.5/5.0 GPM and a 70 °F rise) and DCB-75/100/125/165 heating-only models (75 to 164 MBH maximum CH input), with the floor-standing DCCF/DCBF versions documented on their own page at the same ratings. The AI control automatically sets up the boiler at startup, recognizes natural or LP gas without a conversion kit, and continuously monitors combustion.
Status as printed: both the DCC page and the DCB page print '(While supplies last)' under the product title and the 'Current Documents' tab is empty — all 80+ documents sit under 'Archived Documents' — so Boilers.ca records the line as discontinued (sell-through). The sell sheet prints the construction details: 316L stainless steel heat exchanger and burner with a stainless steel brazed-plate DHW heat exchanger on the combis, 95% AFUE on every model except the DCB-75 at 92% (as printed), wall-hung 30" x 17-3/4" cabinets with 13-9/16" depth on the 75–150 MBH sizes and 21-1/2" on the 165/205 sizes, weights of 94 lb (75/100), 103 lb (115/150), 104 lb (125) and 125 lb (165/205), and system supply/return at 3/4" (1" on 165/205) with the LABOR SAVER manifold included.
Owners of an installed DCC/DCB unit can still service it against the archived manual set, including the Rev. A boiler manuals hosted on the official page; the '(While supplies last)' wording means the line is in end-of-life sell-through rather than actively manufactured. The ratings are the US-market figures Dunkirk prints and no Canadian listing was verified, so canadianStatus stays 'unknown'. Gas work belongs with a licensed contractor against the unit's own documentation.
Highlights
Free 2-year parts & labor limited warranty plus 10-year limited heat exchanger warranty, as printed on the official DCC/DCB sell sheet (unit must be registered within 60 days of the original installation; Trinity extended service terms apply).

Services for Dunkirk Boilers boilers
The official pages print '(While supplies last)' under the product titles with zero current documents, which Boilers.ca records as discontinued (sell-through). The floor-standing DCCF/DCBF versions carry the same badge on their own page.
