    OLD Reznor HRX350

    I am looking for specs for an old Reznor HRX350 make-up air unit.

    The unit was discontinued in 1990. The company no longer has any literature on the product. I am guessing an input of 350MBH( )...looking for a rated output value.

    I am a newb to HVAC and need to provide specs for these units for comparison to replacement units.

    Any help would be appreciated.

    The company still has the literature. It's just not listed exactly like your model number. It shows on the bottom of page 1 of the attachment that its 78% efficient.

    So that would be 273,000 BTUH.

    Instead of learning the tricks of the trade, learn the trade.

    I run with it.

    I called them and they told me they have no specs for the old unit...so a major thanks for the help!
