Laars FTCW199 in practice
The FTCW199 pairs the top FT wall heating input — 199,000 BTU/h as printed on the cover of Document 1487C — with the combi's integrated domestic hot water, making it the one-appliance answer for larger homes that also want on-demand hot water without a separate tank. Natural gas ships as the factory configuration; propane is field-convertible.
Its control uses the combi code table of Document 1487C: two-digit FT codes covering flame, sensor, condensate, fan, gas-leakage, low-water and anti-freeze conditions plus the combi's DHW and mixing-valve entries such as codes 66 and 68, with Soft Lock and Hard Lock recovery per code. Installers confirm the vent route supports the larger input before choosing this size.
Best suited to
- Larger homes whose heat loss approaches the 199 MBH combi ceiling
- Households wanting integrated domestic hot water at the top FT wall input
- One-appliance replacements where an older boiler plus tank must become a single combi

Frequently asked questions
Does the FTCW199 carry the same codes as the FTHW199?
The two-digit code families overlap, but the FTCW199 uses the combi table in Document 1487C, which adds DHW sensor and mixing-valve entries (such as 32, 66 and 68) to the shared FT codes. Always read the code from the combi manual.
What is the FTCW199's rated input?
199,000 BTU/h, as printed on the combi installation manual cover. The series rating and the actual design-day load are confirmed with a heat-loss calculation before sizing.
How much venting does the FTCW199 need?
The FT wall installation documentation allows 2" or 3" PVC, CPVC or approved polypropylene venting to 50 or 100 equivalent feet respectively; the venting tables in the manual and the ULC S636 rules that apply in Canada govern the actual run.
