Control Switch Installation: 2.9.1. Install as indicated in drawing CD12031K9, pg 3 of 4. Install the control switch (items 47, 48 and 49) in a convenient location near existing heater controls. Assure that the area behind the switch has adequate clearance. Interconnect previously installed wire harness to new rear heater switch using same wire color- coding. 2.9.2. Circuit breaker installation as indicated in view 1, 2, 4 and 5. 3. Operation Check: 3.1. Return right fuel shut off to on position. With master switch on, turn the heater control to first position “Fan.” Verify the ventilation fan is operational. Airflow out of the top outlet. 3.2. Heater Control Switch to next position “Heat.” Verify that the ventilation fan is still operational and that the combustion air motor is operating with airflow out the exhaust. Check for voltage at the heater terminal strip numbers 1, 2 and 6. Terminal #3 may or may not have power depending on temperature in area. Rotate heater control switch until power is evident at terminal #3 and heater fires. With fuel pump running, check for fuel leaks full length of new installation. 4. TESTING 4.1 HEATER OPERATIONAL TEST AFTER INSTALLATION: IMPORTANT!! Please complete the followings steps after the new heater is installed in the aircraft. (Heater terminal strip numbered 1 2 3 4 5 6) 4.1.1 Install a temperature probe (min 0-500° F) in the outlet plenum 6-8” aft of the heater. A good location would be approx. 6” aft of the heater or near the thermostat sensor. Usually you can find a small access point somewhere in the ducting aft of the heater. CAUTION: Verify thermal couple is not touching plenum internal wall. 4.1.2 Setting upper limit temperature upper limit switch 4.1.2.1 If your heater is equipped with a CD21252…..  Place a 6” 20G jumper wire with 2 small alligator clips (or the like) across the heater terminal strip numbers 2 and 3, which will bypass the aircraft thermostat. (Fig. 2) CAUTION: Be sure not to short any other terminals.  With the heater running, verify that the outlet plenum temp. is approx. 250°. Adjust the temperature of the heat duct outlet distribution plenum to an average ambient temperature as follows. • For non-pressurized aircraft set switch to a low of 215º and a high of 255º. • For pressurized aircraft set switch to a low of 190˚ and a high of 225˚. NOTE: Adjustment is made by rotating a small 1/16” screw located next to the wires on the side of the switch. It may have a dab of inspectors lacquer over the screw. Rotation clockwise one turn will increase temperature approx. 20° F. Decrease temperature by turning counterclockwise (Fig 3).  After sensor is adjusted, place small drop of tamper proof seal on adjustment screw to lock in settings so as to not change due to vibration. Use a product that can be easily removed for readjustment if necessary.  Remove the jumper wire and verify that the temperature is controlled by the aircraft thermostat from low (approx. 75° F) to medium to high (approx. 250° F) which is what the cycling switch is set at.  Remove the temperature probe sealing the hole with high temperature silicone.

Upper limit adjustments should be made in accordance with aircraft manufacturer’s instructions. 4.1.3 Install the fuel pressure gauge (0-15). Tee into as shown. (Fig. 4)  With the heater running, verify fuel pressure. • Preferred pressure is 8psi. (6.5psi min, 10psi max) Figure 4 4.1.4 Remove the fuel gauge installed in step 4.1.3. Leave the “tee” fitting and cap off for future pressure readings if desired. 4.2 Verify proper installation is completed in accordance with the aircraft maintenance manual. 4.2.1 Verify all wires are secure and free of obstruction and chaffing. 4.2.2 If the hoses need to be replaced, we recommend Sceet-6 (1 ½”) red from the blower to the heater and Ceet-6 (1 ½”) black from outside air to the blower. 4.2.3 For additional information see the “maintenance manual (MM10001)” included with this heater under “Testing after installation or overhaul.” 5. After installation, complete the operation and heat output tests specified in the C&D Associates, Inc. MM10001 Maintenance Manual for aircraft combustion heaters Rev L, dated 5/21/15 or later FAA approved revision. Tests should be accomplished in accordance with section 10.3 operational test, and 10.4 for heat output. Also in accordance with the “Instructions for Continued Airworthiness” “Preflight/Operational check and Shutdown Procedure.” Rev E dated 5-21-15. These FAA-approved Instructions for Continued Airworthiness must be complied with and become a permanent part of the Aircraft Operations and Procedures manual.

DOCUMENTATION: 6.1. Weight & Balance. 6.1.1. If changed remove old heater of __ lbs (verify weight). And install new heater kit of 43 lbs aft of rear cabin bulkhead. The aircraft requires a weight and balance and a 337 must be completed and a copy of the STC attached. The logbook entry should contain the STC #SA01751CH and PMA Supplement #32. Original heater replacement is authorized by way of FAA form 337. Alteration of aircraft by way of STC or PMA supplemental number and date must be recorded in the appropriate aircraft records. 6.1.2. If unchanged removal of the Combustion Heater and the installation of the C&D Associates Products TSO-C20 approved heater will have no net effect on weight and balance or electrical load requirements. 6.2. Insert the following statement (label 21503 provided) in the aircraft flight manual: “C&D Associates Inc. Combustion heater has been installed in this aircraft. Please follow the aircraft-operating manual for combustion heater operating sequence and/or C&D Associates Inc. Instructions for airworthiness” located in MM10001 Rev I dated 8/1/14 or later FAA approved revision.” 6.3. Utilize existing aircraft combustion heater operating instructions or other FAA approved combustion heater operating instructions where applicable. 6.4. Electrical requirements: 24VDC at 15Amp. 6.5. Fuel consumption: Maximum operation 2 gal/hour. DOCUMENTATION AND PARTS REQUIREMENT TABLE DOCUMENTATION Quantity 1. FAA/PMA Supplement #32 ____ 2. Installation Instructions IN12031K9 ____ 3.
