 General
The Paraflo heater is a
self-contained, automatic, indirect-fired, recirculating warm-air space heater. The
heatexchanger design, with three full combustion gas passages at ninety degrees to the
direction of air flow, large volume stainless steel combustion chamber, and a secondary
heat exchanger, insures maximum combustion efficiency. Two pass flame travel within the
combustion chamber provides 75% of the total heat release through stainless steel, for
longevity. Only 25% of the total heat release is obtained through the carbon steel
secondary.
Efficiency
Guaranteed minimum of 80% as measured by
flue gas temperature and C02 content prior to being exhausted and based upon full-rated
operating conditions.
Approvals
Optional controls are available to meet FM
and IRI insurance approval.
