Back cover FOR YOUR SAFETY If you smell gas: 1. Open windows 2. Don't touch electrical switches. 3. Extinguish any open flame. 4. Immediately call your gas supplier. FOR YOUR SAFETY The use and storage of gasoline or other flammable vapors and liquids in open containers in the vicinity of this appliance is hazardous. THIS MANUAL IS THE PROPERTY OF THE OWNER. PLEASE BE SURE TO LEAVE IT WITH THE OWNER WHEN YOU LEAVE THE JOB. All models approved for use in California by the CEC (when equipped with IPI), in New York by the MEA division, and in Massachusetts. Unit heater is certified for non-residential applications. CAUTION To prevent premature heat exchanger failure do not locate ANY gas-fired units in areas where chlorinated, halogenated or acid vapors are present in the atmosphere. Inspection on Arrival 1. Inspect unit upon arrival. In case of damage, report immediately to transportation company and your local Modine sales representative. 2. Check rating plate on unit to verify that power supply meets available electric power at the point of installation. 3. Inspect unit received for conformance with description of product ordered (including specifications where applicable). October, 2002 Heater Parts from ACF Greenhouses INSTALLATION SPECIAL PRECAUTIONS 2 Figure 2 Hinged Bottom for Burner Service (See Dimension “C”, page 19) THE INSTALLATION AND MAINTENANCE INSTRUCTIONS IN THIS MANUAL MUST BE FOLLOWED TO PROVIDE SAFE, EFFICIENT AND TROUBLE-FREE OPERATION. IN ADDITION, PARTICULAR CARE MUST BE EXERCISED REGARDING THE SPECIAL PRECAUTIONS LISTED BELOW. FAILURE TO PROPERLY ADDRESS THESE CRITICAL AREAS COULD RESULT IN PROPERTY DAMAGE OR LOSS, PERSONAL INJURY, OR DEATH. 1. Disconnect power supply before making wiring connections to prevent electrical shock and equipment damage. All units must be wired strictly in accordance with wiring diagram furnished with the unit. 2. Turn off all gas before installing unit heaters. 3. Gas pressure to unit heater controls must never exceed 14" W.C. (1/2 psi). When leak testing the gas supply piping system, the unit and its combination gas control must be isolated during any pressure testing in excess of 14" W.C. (1/2 psi). The unit should be isolated from the gas supply piping system by closing its field installed manual shut-off valve. 4. Check gas inlet pressure at unit upstream from combination gas control. The inlet pressure should be 6" - 7" W.C. on natural gas or 11" - 14" W.C. on propane gas. Purging of gas piping should be performed as described in ANSI Z223.1 - Latest Edition or in Canada in CAN/CGA-B149 codes. 5. All units must be supplied with both combustion air and exhaust piping to the outdoors. 6. Do not install in potentially explosive or flammable atmospheres laden with grain dust, sawdust, or similar airborne materials. In such applications, a blower type heater installed in a separate room with ducting, including appropriate back flow prevention dampers to the dustladen room, is recommended. 7. Installation of units in high humidity or salt water atmospheres will cause accelerated corrosion resulting in a reduction of the normal life span of the units. 8. To prevent premature failure do not located ANY gas-fired unit heaters in areas where chlorinated, halogenated or acid vapors are present in the atmosphere. 9. Maintain separation between units so discharge from one unit will not be directed into the inlet of another. 10. Do not install unit outdoors. 11. Minimum clearance to combustibles is 12 inches from the bottom; 18 inches from the sides; 6 inches from the top and vent connector. 12. Allow at least 6" clearance at the sides and 12" clearance at rear (or 6" beyond end of fan motor at rear of unit, whichever is greater) to provide ample air for comb...
