EXHAUST COLLECTOR 1. Conduct the heater exhaust away from the test area. Use an exhaust extension made of flexible hose (Figure 4, Item 8) not more than ten feet long. Figure 4. Exhaust Venting. TESTING 1. A complete test of the coolant heater consists of the following: a. Fuel flow test (WP 0026). b. Burn test. c. Restriction thermostat test. d. Overheat thermostat test. e. Combustion air blower test. 2. Obtaining equipment for the combustion air blower test may be difficult. Do not do this test if the heater burns properly and the igniter cavity does not show undue carbon deposits. 3. Replace the blower if the heater goes out during test or smokes a lot and has heavy carbon deposits in the igniter cavity (WP 0032). Moderate carbon deposits are normal and do not indicate a bad blower. TM 9-2350-277-40&P 0025 0025‐4
