The Reznor® Model LDAP Series Packaged Downflow Heaters
Reznor® Model LDAP Series Packaged Downflow Heaters are available in three sizes – 400 MBH, 800 MBH, and 1200 MBH. Model LDAP 400 has one heat section; Model LDAP 800 has two heat sections; and Model LDAP 1200 has three heat sections. All Model LDAP heaters are 83% thermal efficient for use with either natural or propane gas.
Each heat section features the Reznor Tcore2 heat exchanger and single burner combustion system. Other features include a single-stage gas valve, multi-try direct spark ignition with timed lockout, pressure switch to verify venter flow, resiliently isolated venter motor, resiliently isolated axial fan and motor assembly, a high temperature limit control, a destratification fan control, and a built-in disconnect switch. Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in control functions.
Cabinet has four suspension points for hanging or may be wall mounted. Designed for ease of installation with an external 24-volt terminal strip and gas line connection.
Model LDAP heaters are certified by the ETL Testing Agency for commercial and industrial installations in United States and Canada.
NOTE:
All Model LDAP high bay packaged heaters are design certified by ETL for use in industrial and commercial installations.
These heaters must be installed in accordance with local building codes. In the absence of local codes, in the United States, the heater must be installed in accordance with the National Fuel Gas
Code, ANSI Z223.1. A Canadian installation must be in accordance with the CSA B149 Installation Codes.
