ABSTRACT:
A specially configured fuel-fired water heater production platform may be used as a natural draft water heater. Alternatively, by modifying an upper end portion of the production platform using associated conversion apparatus, the same platform may be converted to a power vented water heater subassembly, a natural draft direct vent water heater subassembly, or a powered direct vent water heater subassembly to thereby lower the overall production costs for these different types of fuel-fired water heaters.
