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.
•
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
•

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
