Burnham Series 2 208E in practice
The Series 2 208E is one of the eight current cast-iron gas water boiler sizes in U.S. Boiler Company's Series 2 line. Its submittal row prints 241 MBH input, 202 MBH DOE heating capacity and a 176 MBH AHRI net water rating (1.15 allowance) at 84.0% AFUE, with 8 sections, a 7" vent diameter, a 3/4" NPT gas connection and 7 gallons of water content.
The boiler measures 28 in. wide x 27 in. deep, ships at 502 lb (empty weight 431 lb) and is a chimney-vented atmospheric cast-iron design with a heavy-duty steel base. Input ratings apply from sea level to 2,000 ft; conversion kits are documented for LP combustion (109706-01/-02, 109729-01) and for the 2,001–5,400 ft and 5,401–10,000 ft altitude bands.
Boilers.ca records the printed row for the 208E; no official Canadian-sales statement was found, so canadianStatus stays 'unknown', and gas, combustion and venting work belongs with a licensed contractor against the Series 2e I&O manual.
Best suited to
- 241-MBH-class residential loads (202 MBH DOE heating capacity)
- Chimney-vented cast-iron replacements on the long-running Series 2 platform
- Systems needing 7 gallons of boiler water content in a 8-section casting
