HTP ELU-199WCN
The HTP ELU-199WCN is the 197 MBH-class wall-hung combi of the Elite Ultra line: 19.7 to 197 MBH central-heating input (NG) with 19.7 to 197 MBH domestic-hot-water input, recorded from the CH/DHW table printed on the official ELU page.

HTP ELU-199WCN in practice
The ELU-199WCN is a wall-hung combination unit of HTP's current Elite Ultra (ELU) line — the code reads wall-hung (W), combi (C), natural gas (N) with liquid-propane conversion kits included. The official model table prints its central-heating input at 19.7 to 197 MBH (natural gas; the LP rows print 19.2 to 192 MBH) and its domestic hot water input at 19.7 to 197 MBH.
The page's XtraTech heat exchanger section describes a patent-pending durable stainless steel heating technology with a pipe surface up to 400% larger than conventional designs, and the page claims an 11:1 turndown and up to 96% thermal efficiency when the outdoor sensor is used. The model table itself prints no AFUE, weight or dimension rows, so none are recorded here; the model's installation and operation manual is doc 420010970305 (LP-700 Rev.000, 1.24.23) or 420011303900 (2.28.22) as grouped on the official documents page.
This record is current — the ELU line appears in HTP's current 'Elite Ultra Wall and Floor' navigation with the model table live. Boilers.ca found no official statement of Canadian sales on htproducts.com, so canadianStatus stays 'unknown'; gas and combustion work belongs with a licensed contractor against the model's own I&O manual.

Frequently asked questions
Is the HTP ELU-199WCN a combi boiler?
Yes — the WCN code means wall-hung combi: the official table lists a domestic hot water input range for it (19.7 to 197 MBH), so the unit makes hot water directly.
How is the ELU-199WCN fueled?
The official page states boiler and combi units ship as natural gas units and come standard with liquid propane conversion kits; on the 199 models the table prints separate NG and LP input rows.
Does the ELU-199WCN record show an AFUE?
No — the official ELU model table prints CH and DHW input ranges only, with no AFUE, weight or dimension rows, so Boilers.ca records the inputs and the page's efficiency claims without inventing per-model ratings.
