Safety Precautions 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. inlet venturi, combustion cones and filter (if applicable). -- Check for general cleanliness. Clean if necessary. -- Thorough inspection of the heater’s component parts for corrosion, stripped threads, etc. with subsequent parts replacement as 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.
-- If a leak is detected, check the components involved for cleanliness in the thread areas and proper application of pipe compound before further tightening. 12. The heater is designed for either L.P. vapor withdrawal or natural gas, depending on model number. Do not use this heater in an LPG liquid withdrawal system. Do not permit LPG in liquid form to enter the heater at any time. -- Tighten the gas connection as necessary to stop the leak.
GAS TRAIN ASSEMBLY Your heater is supplied with one of the following gas train assemblies. Refer to the appropriate illustrations.

ZONE CONTROL PANEL COMPONENT FUNCTION AND INSTALLATION The zone control panel is a remote mounted control system allowing the operation of a specific amount of heaters within a certain zone of the building. These panels will control the following quantity of heaters depending on fuel type. Model and Heat Output I40 (40,000 BTUH) Modulating System Fuel L. P.
WARNING Fire or Explosion Hazard Start-Up Instructions FIG. 7 ■ Do not force the safety gas control valve button. ■ Use only your hand to depress the gas control button. THERMOSTATIC HEAD Never use any tools. ■ If the button will not depress by normal hand pressure, the control should be replaced by a qualified service person. ■ Force or attempted repair may result in fire or explosion, causing property damage, severe injury, or death.
Cleaning Instructions LEAD CA U TIOEND N OF THERMOCOUPLE ■ Disinfectants utilized in agricultural animal confinement buildings may contain chemicals damaging to components of the heater. 6. Return the heater to its normal hanging position and relight the heater. FIG. 9 THERMOFUSE ■ Protect the safety gas control valve and pressure valve by wrapping these components with a plastic COVER bag before disinfecting.
FIG. 11 WATER HOSE 8. Relight the heater to dry out the cones and the venturi tube. B. FILTER A. During continued use: - Remove filter and shake off dust. - Do not squeeze or tap filter while filter is installed on heater. Doing so will cause dust to be blown into venturi tube or combustion cones. B. After continued use or before building repopulation: 4. Repeat steps 2 and 3 until water runs clean. 5. Remove the plastic bag. Inspect the cones and venturi tube to make sure these areas are clean. 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.
1. Disconnect the gas hose. 2. Loosen the gas supply tube compression nut and swing the tube away from the safety control valve.
