1. Electric heat steps and airfl ow range depends on voltage and size. Consult the air pressure drop tables for specifi c number of steps for a
given voltage.
2. 3.5” is minimum gas pressure for full fi ring rate. 3.0” is acceptable at reduced fi ring rate.
3. Weights are for components only and need to be added to the extended cabinet weights. The diffuser is required in the ex-
tended cabinet for any unit with hot water or fi nal fi lter option.
