! WARNING
This furnace is not designed for use in mobile homes, trailers, or recreational vehicles. Such use could result in property damage and/or death.
The 820SB/821SB 4-way Multipoise Gas Furnaces feature Bryant’s QuieTechTM noise reduction system for quiet induced draft operation. Applications are easy with our 4-way multipoise design, through-the -furnace downflow venting, 13 different venting options, and easy service access. An inner blower door is provided for tighter sealing in sensitive applications. The 820SB/821SB furnaces are factory shipped for use with natural gas and convertible to propane with approved accessory kit. The 821SB – Low NOx units are designed for California installations and meet 40 ng/J NOx emission limits. Can be installed in air quality management districts with a 40 ng/J NOx emissions limit.

NOTE:

1. A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter media such as contained in a factory – authorized accessory filter rack. See accessory list. To determine airflow performance without this filter, assume an additional 0.1-in. w.c. available external static pressure.
2. Adjust the blower airflow setting as necessary for the proper air temperature rise for each installation. 3. Airflows over 1800 CFM require bottom return, two-side return, or bottom and side return. A minimum filter size of 20″ x 25″ (508 x 635 mm) is required. 4. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return 5. The – entry indicates unstable operating conditions
