WHEN INSTALLED ON BEECHCRAFT BARON WITH HARTZELL SCIMITAR PROPELLERS. a. For proper air balance, exhaust pipe needs scarf angle modification. Trim and smooth by filing, the exhaust pipe scarf angle, (extending out of the aircraft, long end forward) with supplied template. (Connect the exhaust pipe with the attaching screws.) NOTE: Exhaust pipe to have 22 deg scarf angle, long end aft. See “Exhaust Template” below and figure 3 on pg 4. Due to printer variations this template is for reference only. An angle gauge should be used to determine angle as the length and angle are critical measurements.

Modify Combustion Air Inlet Assembly P/N CD22349 to 30° as shown below. Below the etched information on the combustion air inlet, make a permanent marking of “30°” instead of the etched 15. Install Combustion Air Inlet Assembly P/N CD22349 with the retainment bolt and connect the hose to the combustion air blower inlet adaptor with the hose clamp. Due to printer variations this template is for reference only. An angle gauge should be used to determine angle as the length and angle are critical measurements. 30 DEG MARKING Figure 4: Combustion air inlet (30 deg scarf) 5. WIRING A. Reconnect airframe wiring to heater terminal strip marked 6-1 as removed in section 2c. B. An additional braided ground wire is attached to the terminal strip attachment screw and should be routed along with the terminal #5 ground wire to the airframe grounding location (left shelf support). This braided ground wire is identified by red warning tag. NOTE: Give special attention to proper grounding. The C&D heater has additional grounds that are required. C. Remove existing connector to heater fuel pump and install supplied female snap plug, P/N 60397, using appropriate insulated terminal lug crimper, such as a Paladin P/N PA8021. Insert male end of connector, C&D Associates, Inc. 302 POST ROAD, BUCHANAN, MI 49107 USA PH: 269-695-7469 FX: 269-695-6004 WEB: www.cdaircraftheaters.com EMAIL: sales@aircraftheater.com INSTALLATION INSTRUCTIONS IN50000K33 Page 6 of 8 Dated 3/17/09 Rev J dated 3/17/15 attached to the pump, to female end of the airframe wiring and verify connection. Use appropriate heat gun set to approx. 180° F to heat shrink seal both ends of the connector. Secure wiring to the airframe. D. Restore electrical power to the airplane (Ref 24-36-00, 301, ELECTRICAL POWER – CONNECT) and verify wiring connections. See Figure 6. 6. AFTER INSTALLATION A. Complete the “Heater Operational Test After Installation” (Step 8) prior to replacing the nose cone with the attaching screws. 7. HEATER CONTROL SYSTEM A. Refer to the aircraft service manual. 8. HEATER OPERATIONAL TEST AFTER INSTALLATION: (Recommended) A. Install a temperature probe (min 0-500° F) in the outlet plenum aft of the heater. Find a small access point somewhere in the ducting aft of the heater near the thermostat sensor or drill a small 1/8” hole through the heat distribution plenum allowing a thermo couple to enter unobstructed, into the heated air stream. This hole may be sealed after completion of test with high temp silicone. CAUTION: Verify nothing will be damaged in this process. Never drill into combustion heater itself! CAUTION: Verify thermal couple is not touching plenum internal wall. B. Install the fuel pressure gauge (0-15). Tee into as shown. (Fig. 5) C. With the heater running, verify fuel pressure. Preferred pressure is between 7 psi min to 8 psi max. D. With the heater running, verify that the temperature is controlled by the aircraft thermostat from low (approx. 75° F) to medium to high (approx. 250° F) E. Place a jumper wire across the heater terminal strip HEATER FUEL SUPPLY FROM FUEL PUMP FUEL PRESSURE GAUGE 1-15 PSI FOR AV GAS HEATER numbers 2 and 3, which will bypass the aircraft thermostat and verify that the outlet plenum temperature is approx. 250°. Figure 5 CONNECTION a. If upper limit temperature needs adjustment the CD21252 limit switch is located in the nose wheel well on the tail of the heater. The rectangular limit switch is located next to the round automatic overheat switch. b. Adjust the temperature of the heat duct outlet distribution plenum to an average ambient temperature of 225º. Typical readings will be a low of 215º and high of 255º. Adjustment is made by rotating a small 1/16” screw located left of the wiring harness plug in on the side of the switch. c. Rotation clockwise one turn will increase temperature approx 20° F. Decrease temperature by turning counter clockwise. d. After adjustments is made remove the jumper wire and recheck temperature operation. e. 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. It is recommended to use a product that can be easily removed for future adjustment if required. F. Remove the temperature probe sealing the hole with high temperature silicone. G. Remove the fuel gauge installed in step 8.B. Leave the “tee” fitting and cap off for future pressure readings if desired and pressure check all fuel connections after reassembly. For additional information see the “maintenance manual (MM10001)” included with this heater under “Testing after installation or overhaul.” C&D Associates, Inc. 302 POST ROAD, BUCHANAN, MI 49107 USA PH: 269-695-7469 FX: 269-695-6004 WEB: www.cdaircraftheaters.com EMAIL: sales@aircraftheater.com INSTALLATION INSTRUCTIONS IN50000K33 Page 7 of 8 Dated 3/17/09 Rev J dated 3/17/15 Figure 6: Wiring Schematic 9. AIRWORTHINESS LIMITATIONS: A. Full compliance with the enclosed FAA approved C&D Associates Inc. ‘Combustion Heater Airworthiness Limitations’ is required.
