1. Do not attempt to install, repair or service this heater or the gas supply line unless you have continuing expert training and knowledge of gas heaters. Qualifications for service and installation of this equipment are as follows: QUALIFICATIONS FOR SERVICING AND INSTALLATION: a.
-- Insure proper clearance of heater to nearest combustible materials. -- Leak check of all pipe joints and hose connections. -- Thorough cleaning of the exterior of the heater, its inlet venturi, combustion cones and filter (if applicable). -- Check for general cleanliness. Clean if necessary. -- Check for tightness of the gas hose connections. 14. A qualified service person shall inspect the heater and its gas train at least on an annual basis.
-- With the main burner in operation, check all connections, hose connections, fittings and joints as well as the gas control valve inlet and outlet connections with approved gas leak detectors. 13. Infraconic heaters require a regulated gas supply to the gas inlet. Exceeding the gas inlet pressure rating can result in poor per formance and unreliable operation. Refer to page 4 of this manual for information on gas pressures relating to specific models.
GAS TRAIN ASSEMBLY This heater is supplied with one of the following gas train assemblies. Refer to the appropriate illustrations.

ZONE CONTROL PANEL FUNCTION AND INSTALLATION With proper (5 PSIG) gas pressure supplied, spark ignition heaters will operate in the standard ON/OFF mode when electrically connected to a building environment controller or thermostat If you require two stages of heat for greater temperature control, a two stage solenoid operated zone panel must be installed.
Start-Up Instructions Follow steps 1-5 on initial start up after heater installation by a qualified gas heater service person. For normal startup, simply turn the building thermostat above room temperature. 1. 2. 3. 4. 5. Connect the heater to an approved electrical supply and building’s temperature control system. Open all gas supply valves to the heater and check for gas leaks at all connections using approved leak detectors.
Cleaning Instructions 5. Inspect the cones and venturi tube to make sure these areas are clean. It is important to clean the heater and the optional dust filter on a regular basis to maintain proper combustion and to eliminate future problems. Do not clean the heater with water or other liquids. The frequency of cleaning will var y depending upon livestock being raised and overall ventilation of the building. Problems associated with lack of cleaning typically are: 6.
Maintenance Instructions 1. Have your gas supplier check all gas piping annually for leaks or restrictions in gas lines. Also, at this time have your gas supplier clean out the sediment trap on the zone control panel of any debris that may have accumulated. 2. The heater’s surrounding area shall be kept clear and free from combustible materials, gasoline, and other flammable vapors and liquids. 3. Regulators can wear out and function improperly.

Electrical Connection and Ladder Diagram CAUTION: REFER TO THE HEATER'S ELECTRICAL CONNECTION DIAGRAM WHEN SERVICING TO AVOID WIRING ERRORS AND HEATER MALFUNCTION. CHECK FOR PROPER OPERATION AFTER SERVICING.
Burner Orifice Metering device used to feed gas to combustion cones at a specific flow rate. Canopy Reflective aluminum heat shield for heater. Double Combustion Chamber Made of special alloy steel. This is where combustion of gas occurs, providing radiant heat used in the warming process. Consists of small inner cone and large outer cone Gas Control Valve Component that houses electromagnet which is energized by voltage and therefore opens or closes to supply or shut off the flow of gas to the burner.
