Features And Benefits - Lennox Energence LGH Manual

PER FO R M A N C E/QUALIT Y AND C E MARK O PTION
PERFORMANCE/QUALITY
• Components bonded for grounding to meet safety standards for servicing required by Underwriters Laboratories (UL)
and the International Electrotechnical Commission (IEC)
• Cooling performance is rated at test conditions included in Air-Conditioning, Heating and Refrigeration Institute (AHRI)
Standard 340/360 while operating at rated voltage and air volumes
• International Organization for Standardization (ISO) 9001 Registered Manufacturing Quality System
CE MARK OPTION
• The CE mark has been added to our rooftop product line as a configure to order (CTO) option. This optional construction
allows units to be sold into countries requiring CE marking for rooftop products
• CE marked units meet the requirements of the Machinery Directive 2006/42/EC, Low Voltage Directive 73/23/EEC, EMC
Directive 89/336/EEC, and Gas Directive 90/396/EEC. Declaration of conformity certificates will be provided for each CE
marked unit on demand
• Key features of this option over and above standard product features are:
• Touch-proof electrical components meeting the requirements of EN 60529
• Branch circuits over 0.5 kW load have overcurrent protection
• Rotary style/finger safe disconnect switch with locking handle prevents disconnect door from being opened with the
power on. Padlock can be applied to lock the disconnect switch in the OFF position
• The factory wiring has been redesigned for separation of high and low voltage circuits
FEAT UR ES AND BENEF ITS
HEATING SYSTEM
Heat Exchanger
• Tubular construction, aluminized steel
• Life-cycle tested
NOTE - Optional Stainless Steel Heat Exchanger is
required if mixed air temperature is below 7°C.
B B • Aluminized steel inshot burners
• Direct spark ignition
• Electronic flame sensor
• Combustion air inducer
• Redundant automatic dual stage gas valve with manual
shut-off
Electronic Pilot Ignition
• Electronic spark igniter provides positive direct ignition
of burners on each operating cycle
• Permits main gas valve to stay open only when the
burners are proven to be lit
• If loss of flame occurs, gas valve closes, shutting off the
gas to the burners
• LED indicates status and aids in troubleshooting
• Factory installed in the control section
Limit Controls
• Redundant limit controls with fixed temperature setting
• Protects heat exchanger and other components from
overheating
Safety Switches
• Flame roll-out switch
• Flame sensor
• Combustion air inducer proving switch
• Protects system operation
Required Selections
Gas Input Choice - Order one:
• Low Gas Heat, 1 Stage (49.5 kW)
• Standard Gas Heat, 2 Stage (49.5/68.5 kW)
• Medium Gas Heat, 2 Stage (68.5/91.9 kW)
• High Gas Heat, 2 Stage (91.4/123 kW)
NOTE - Two-stage heat models can be operated with four
stages of gas heating when controlled in either
zone sensor, Discharge Air Control, or fresh air
tempering mode on the Prodigy
(available when using the CS8500 thermostat or
when connected to Building Automation Systems
using BACnet, LonTalk, or S-Bus protocols). See
Gas Heating Specifications table.
