Reznor Reznor® RP Series Duct Furnaces Model RP400

Reznor® RP series rooftop duct furnaces are designed to be used as the heating component in a heating, heating/cooling or makeup air system. The RP series furnaces are certified for 80% thermal efficiency for use with either natural or propane gas, as specified, in sizes from 125,000 through 400,000 BTUH input. The furnace includes an integral power vent system which provides metered combustion air, dilutes flue products and eliminates the need for a vent cap. The weatherized, aluminized steel cabinet is designed for outdoor mounting. A separate blower system is required for air delivery. The furnace has a patented Reznor® Thermocore® aluminized steel heat exchanger with venturi-design tubes. The die-formed burners are of aluminized steel and include flared ports with a stainless steel insert. Standard features include a spark-ignited intermittent pilot and a single stage 24-volt gas valve. Each unit has all the required limit and safety controls including a venter pressure switch which verifies power vent flow prior to allowing operation of gas valve. For automatic operation, each unit is wired for field connection to a remote 24-volt thermostat.
