Suburban SF-20FQ (2551A) Model and Installation Compatibility
The complete Suburban SF-20FQ furnace, manufacturer part 2551A, is a 20,000 BTU/h LP-gas, 12V ducted RV furnace. This SF-FQ configuration is designed for interior service access and a front (inside) gas connection, with a small exterior vent terminal rather than the SF-Q access-door arrangement.
