SAFETY INSTRUCTIONS TO THE INSTALLER Before installing this unit, please read this manual to familiarize yourself on the specific items which must be adhered to, including maximum external static pressure to unit, air temperature rise, minimum or maximum CFM and motor speed connections. TO THE OWNER A warranty certificate is provided with the unit. Read the warranty carefully and note what is covered. Keep the warranty certificate in a safe place so you can find it when necessary.
RISQUE D'EMPOISONNEMENT AU MONOXYDE DE CARBONE Advertencia especial para la instalación de calentadores ó manejadoras de aire en áreas cerradas como estacionamientos ó cuartos de servicio. Las emisiones de monóxido de carbono pueden circular a través del aparato cuando se opera en cualquier modo. CO can cause serious illness including permanent brain damage or death.
• The base should also be located where no runoff of water from higher ground can collect in the unit. ROOFTOP INSTALLATIONS ONLY: NOTE: To ensure proper condensate drainage, unit must be installed in a level position. • To avoid possible property damage or personal injury, the roof must have sufficient structural strength to carry the weight of the unit(s) and snow or water loads as required by local codes. Consult a structural engineer to determine the weight capabilities of the roof.
1. 2. 3. 4. Make notation on delivery receipt of any visible damage to shipment or container. Notify carrier promptly and request an inspection. In case of concealed damage, carrier should be notified as soon as possible-preferably within 5 days. File the claim with the following supporting documents: a. Original Bill of Lading, certified copy, or indemnity bond. b. Original paid freight bill or indemnity in lieu thereof. c.
The rating plate is stamped with the model number, type of gas and gas input rating. Make sure the unit is equipped to operate on the type of gas available. The gas line installation must comply with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1.
All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters (See NBFU Manual 58). For satisfactory operation, propane gas supply pressure must be within 9.7 - 10.3 inches W.C. at the manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors: 1. Vaporization rate, which depends on (a) temperature of the liquid, and (b) wetted surface area of the container or containers. 2. Proper pressure regulation. 3.
The units are designed for operation on 60 hertz current and at voltages as shown on the rating plate. All internal wiring in the unit is complete. It is necessary to bring in the power supply to the contactor as shown on the unit wiring diagram which is supplied with each unit. The low voltage wiring must be connected between the unit control panel and the room thermostat.
All line voltage connections must be made through weatherproof fittings. All exterior power supply and ground wiring must be in approved weatherproof conduit. Low voltage wiring from the unit control panel to the thermostat requires coded cable. See below for ground level and rooftop wiring. Note:Junction box location shown is optional and is for illustration purposes only.
CIRCULATING AIR AND FILTERS AIRFLOW CONVERSION Units can easily be converted from horizontal to down-discharge airflow delivery. In down-discharge or high static installations, the installer should measure the total external static and review the blower performance charts before performing the installation. In some installations it will be necessary to change the blower speed to provide proper air flow. Horizontal Air Flow Single phase models are shipped without horizontal duct covers.
INSTALLATION - COMBUSTION AIR INTAKE HOOD 1. Locate the second hood. 2. Using the three screws provided, attach the hood (with the opening facing down) to the heat exchanger access door. CONDENSATE DRAIN CONDENSATE DRAIN CONNECTION DRAIN CONNECTION A 3/4” NPT drain connection is supplied for condensate piping. An external trap must be installed for proper condensate drainage.
5. The compressor and outdoor fan will be de-energized when the thermostat opens. 6. The indoor blower continues to run at low cool speed for approximately 60 seconds after the thermostat is satisfied. This allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor blower is deenergized. NOTE: A 180-second anti-short cycle is integral to the control and prevents recycling of the compressor. FAN ONLY 1. Thermostat calls for FAN ONLY by energizing “G”. 2.
11. Turn on the electrical power supply to the unit. 12. Set the thermostat to desired setting. Open to Atmosphere Manometer Hose High Fire Regulator Adjust Regulator Vent Outlet Pressure Boss Gas Supply And Manifold Check Gas supply pressure and manifold pressure with the burners operating must be as specified on the rating plate. A Gas Inlet Pressure Check Gas inlet pressure must be checked and adjusted in accordance to the type of fuel being consumed.
11. Turn off all electrical power and gas supply to the system. 12. Remove manometer hose from outlet pressure boss. 13. Turn outlet pressure test screw in to seal pressure port (clockwise, 7 in-lb minimum). 14. Turn on electrical power and gas supply to the system. 15. Turn on system power and energize valve. 16. Using a leak detection solution or soap suds, check for leaks at pressure boss screw. Bubbles forming indicate a leak. SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
NOTE: Heating airflow must be adjusted to provide the temperature rise shown on rating plate. Blower speeds are programmed to deliver adequate airflow at rated external static pressure (ESP). Refer to airflow table provided in the Appendix for details. Limit Check Check limit control operation after 15 minutes of operation by blocking the return air grille(s). 1. After several minutes the main burners must go OFF. Blower will continue to run. 2.
Cooling Operation NOTE: Mechanical cooling cannot be reliably provided at ambient temperatures below 50° F. 1. Turn on the electrical power supply to the unit. 2. Place the room thermostat selector switch in the COOL position (or AUTO if available, and if automatic changeover from cooling to heating is desired). 3. Set the room thermostat to the desired temperature. TROUBLESHOOTING IGNITION CONTROL ERROR CODES The following presents probable causes of questionable unit operation.
If the control senses an open pressure switch during the pre-purge cycle, the induced draft blower only will be energized. If the pressure switch opens after ignition has begun the gas valve is de-energized, the circulator blower heat off cycle begins, and the induced draft blower remains on. The diagnostic LED (red) code is two (2) flashes. PRESSURE SWITCH STUCK CLOSED A stuck closed pressure switch can be caused by a faulty pressure switch or faulty wiring.
MAINTENANCE Have the gas heating section of the unit checked at least once a year before the heating season begins, to be sure that the combustion air inlet and flue outlet hoods are not blocked by debris, which would prevent adequate combustion air and a properly operating vent system. FILTER REPLACEMENT OR CLEANING A return air filter is not supplied with this unit; however, there must be a means of filtering all of the return air.
CLEANING BURNERS 1. Shut off electric power and gas supply to the unit. 2. Remove the screws securing the manifold to the burner retention bracket. Remove the manifold and rotate each burner counterclockwise to remove. 3. Remove the burners. 4. Use a bottle brush to clean burner insert and inside of the burners. 5. Replace burners and manifold, inspect the burner assembly for proper seating of burners in retention slots. 6. Reconnect electrical power and gas supply. Check the burner flames for: 1.

PACKAGE UNITS - DUAL FUEL & GAS HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin. REPLACE OR CLEAN FILTER IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
