Raypak XVers L H7-726L in practice
The H7-726L is the 725 MBTUH size of the XVers L, the condensing firetube line Raypak markets as the 399-850 MBTUH expansion of the XVers family. Product submittal 241896 prints 725 MBTUH input, 705 MBTUH output, 97.3% AHRI thermal efficiency and 7:1 turndown for this size, with 2-1/2" NPT water connections, a 6 in flue, a 6 in combustion-air intake, a 1-1/4" NPT gas connection, 710 lb operating weight and 17 gal water content.
Like the rest of the XVers L range it runs on the VERSA IC control with cascade capability up to eight boilers and Raymote connectivity, vents as a Category IV condensing appliance, and carries ASME construction with indoor/outdoor rating per the product page model data. The I&O manual is Raypak 241782, published in English and French, and the rating data above comes from submittal 241896.
Best suited to
- Commercial hydronic loads near 725 MBTUH input
- Plants standardising on the XVers L condensing firetube platform
- Retrofit or new builds needing Category IV condensing venting and up to 8-boiler cascade
