VSUB-SERIES UNIVERSAL BLOWER DESCRIPTION
The VSUB-Series Universal Blowers are a multi-purpose adjustable-fixed speed or automatic-variable speed blower. It can vent natur-
al gas, LP-gas and oil fired heating appliances, clothes dryers or be used as a utility blower that will handle up to 575° F. It can also
be used as a adjustable-fixed speed or as an automatic-variable speed combustion air intake blower. All models are supplied with the
model PSA-1 Fan Proving Switch which will disable the burner(s) if an exhaust/supply malfunction should occur, and a FFP-1 fire
/freeze limit that will shut the VSUB Blower off in the event of extreme temperature swings for combustion air applications. The VSUB
Blower is rated for indoor or outdoor installation. Use positive pressure rated vent on the discharge side of the blower when venting
flue gases and mounting indoors. Refer to heating appliance manufacturer's instructions regarding specific venting requirements.
