In addition, the following precautions should be observed when selecting a mounting site. X. Direct heated airstream toward area having greatest heat loss. 27 For" multipi^insfallatibris, ’l^at^H^ters so “ffiaf each will warm a specific area* Arrange so that overall air pattern results in continuous circular flow —of-war-m-air—throughout-space^- 3. Do not locate Heater in areas where combustion — air is' -limited:; -oris1 "not-repla-ced:--------- 4. If located in spaces equipped with exhaust fans, , provide sufficient makeup air to allow proper venting of Heater. \ 5. Two 1/2-inch pipe tappings are provided in top casing for use in suspending Heater. Use pipe unions to join Unit Heater to ceiling hangar. Two additional 1/2-inch pipe tapped brackets are supplied for bal-anting Heater. IV. WIRING Make all electrical connections in accordance with the National Electric Code and any local codes that may apply. If aluminum conductors are to be used, the wire size selected must have a current capacity not less than that of the copper wire specified and must not create a voltage drop between the service panel and the unit ...... in excess of 2% of the unit rated voltage. As a minimum, aluminum wire must be treated to prevent oxidation. With electric power turned off, recheck all electrical -connections -(both-factory and-field) for tightness. Be -sure to check power supply connections, especially if aluminum conductors are used. The Blower Unit Heater is completely wired at the factory and is ready for connections to power source, ( See wiring diagram. The heat anticipator on the thermostat should be set at 0.8 amps. —2— SEP/10/2008/WED 09:32 AM UTC TECH PUB FAX No. 31 7 240 5662 P. 003/006 TABLE III—THROW CHART Model Velocity High Speed ft/min High Speed Low Speed EFFECTIVE THROW* AND MOUNTING HEIGHT CFM Temp Rl&e F CFM Temp Rise F Distance from Floor to Top of Heater In Ft. 8 10 12 14 16 19 20 22 24 26 20 30 32 150-...
