Units with two point suspension (Threaded Rod Suspension) incorporate a level hanging feature. Depending on what options and accessories are being used, the heater may not hang level as recieved from the factory. Do not hang heaters with deflector hoods until referring to the"Installation Manual L / for Deflector Hoods" and making the recommended preliminary adjustments on the heater,while the heater is resting on the floor. The units can be mounted with 3/8"-16 threaded rod as follows: (Suspension with Pipe Adapter Kit) • On each piece of threaded rod used, screw a nut a distance of about 1"onto the end of the threaded rods that will be screwed into the unit heater. • Place a washer over the end of the threaded rod and screw the threaded rod into the unit heater weld nuts on the top of the heater at least 5 turns, and no more than 10 turns. Tighten the nut first installed onto the threaded rod to prevent the rod from turning. • Drill holes into a steel channel or angle iron at the same center-line dimensions as the heater that is being installed. The steel channels or angle iron pieces need to span and be fastened to appropriate structural members. • Cut the threaded rods to the preferred length, place them through the holes in the steel channel or angle iron and secure with washers and lock nuts or lock washers and nuts.A double nut arrangement can be used here instead of at the unit heater(a double nut can be used both places but is not necessary). • Do not install standard unit heaters above the maximum mounting height shown in Table 19.1. NOTE: A pipe hanger adapter kit, shown in Figure 5.3, is available as an accessory. One kit consists of drilled 3/4" IPS pipe caps and 3/8"- 16 x 1-3/4" capscrews to facilitate threaded pipe suspension. • 6-580.14 5 INSTALLATION - VENTING A WARNING in Table 6.1,T, making thee vent system as gst possible.

If inlet pressure exceeds 14"W.C., a gas pressure regulator must be added upstream of the combination gas valve. 6-580.14 15 START-UP PROCEDURE Main Burner Adjustment It may also be necessary to adjust the manifold position in The gas pressure regulator(integral to the combination gas addition to adjusting air shutters to obtain proper flame.

For intermittent pilot systems, both the main burner and pilot are turned off 100% when the thermostat is satisfied. For all units, the system will attempt to light the pilot for 70 seconds. If the pilot is not sensed, the ignition control will wait approximately 6 minutes with the combination gas control closed and no spark.After 6 minutes, the cycle will begin again. After 3 cycles, some ignition controllers lockout for approximately 1 hour before the cycle begins again. This will continue indefinitely until the pilot flame is sensed or power is interrupted to the system. Refer to Table 18.1 for control code descriptions. Specific descriptions of the control sequence for different control codes are listed below. 1. The thermostat calls for heat. 2. The power exhauster relay is energized, starting the power exhauster motor. Once the motor has reached full speed, the differential pressure switch closes. 3. The pilot valve opens and the ignitor sparks for 70 seconds in an attempt to light the pilot. 4. Once the pilot is lit, the flame sensor proves the pilot and stops the ignitor from sparking. 5. On single stage units,the main gas valve is opened and the main burner is lit to 100%full fire. On two stage units, the gas valve may open at either 50% or 100%, depending on what the two stage thermostat is calling for. 6. The air mover starts after 30 to 90 seconds to allow the heat exchanger to warm up. 7. The unit continues to operate until the thermostat is satisfied, at which time both the main and pilot valves close 100%. 8. The air mover stops after 30 to 90 seconds to remove residual heat from the heat exchanger. 6-580.14 17 UNIT AND CONTROL OPTIONS Figure 18.1 - Factory Mounted Option Location Uy o MAI 4ll! lEll - _. eYi.;t V'4 a••‘',I1II.4Ai,11 1 0n11 1.-1111..1111-1111_1L.1_1,4%7-ds2).V\N",1)I1)1‘,1) 0 ' IS l e' / ' cI. eJ Illi _ :yam : _ . -eME II17 `\"J' - ,lam ice.. _ .A,4l..EA All units include the standard (STD)features.
