pipe, fittings, and joints.a. Clean terminal screens. Terminals must be freeof obstruction, undamaged, with screens securelyin place.b. Inspect and clean the air filter as needed. Thefilter can be cleaned using water. See Figure 39,Item 11, for location.c. Terminal Wall thimbles (if used) must be weathertight.d. Pipe must be full round shape, and show no damagefrom impact or excessive temperature.e. Ensure that there is nothing obstructing the flowof combustion air and/or flue gas.f. Inspect and clean piping with soft bristle brushand vacuum to remove any lint, soot, or otherdirt.g. Replace immediately if any signs of deteriorationor corrosion are present.h. Pipe must be supported at minimum five (5) footintervals and must not sag.i. All vent joints must be secure and watertight.j. All air intake joints must be secure and airtight.k. Horizontal vent tee drain or vertical vent teedrain (if used) must have minimum 6 inch trapand allow condensate to flow freely. To Clean:i. Disconnect drain tube from drain fitting.ii. Flush drain tube with water. Fill trap withwater.iii. Securely fasten drain tube to drain fitting,providing gas-tight and watertight seal.l. If pipe must be disassembled for removal ofobstructions or resealing of joint, see Section III,Paragraph B.4. Inspect Condensate Drain Trap andDrain Line (Monthly)a. Inspect condensate trap water level. If low, addwater to bring level to trap discharge.b. Ensure condensate can flow freely to drain.5. Inspect Pilot and Main Burner Flames(Monthly).a. Remove jacket front panel.b. View flames through Flame Observation Port.c. Adjust thermostat to highest setting.d. Check pilot flame. See Figure 26. The pilot producesthree (3) flames. The center flame shouldbe steady, medium hard blue enveloping 3/8 to1/2 inch of sensing probe. If flame is yellow andlazy, follow instructions TO TURN OFF GASTO APPLIANCE (see Figure 27), and contactqualified agency.e. Check main burner flames. See Figure 26. Flameshould have clearly defined inner cone with noyellow tipping. Orange-yellow streaks causedby dust should not be confused with true yellowtipping. If yellow flames are observed, followinstructions TO TURN OFF GAS TO APPLI-ANCE (see Figure 27), and contact qualifiedservice agency.6. Combustion Chamber/Burners . Inspect forblockage or soot accumulation (annually).a. Remove Main Burners. See Figure 30.1. Remove front door.2. Remove air box cover.3. Disconnect ignition wire, sensor wire,ground wire and gas valve wiring.4. Disconnect manifold unions at pilot valveand main gas inlet on right side of air box.5. Remove attachment screws holding air boxto front of combustion chamber.6. Remove burner/fuel train assembly fromcombustion chamber.7. Inspect and clean burners with soft bristlebrush and vacuum to remove any dirt andlint.8. If burners show signs of deterioration or corrosion,replace immediately.9. Check gas orifices for dirt and lint. Clean asnecessary.10. Inspect heat exchanger and combustionchamber. Clean heat exchanger withstraight handle wire brush and vacuum heatexchanger and combustion chamber.1. Exercise care during vacuuming toavoid damaging base insulation.11. Inspect combustion chamber/burner assemblygaskets and replace if required.12. Install burner/fuel train assembly and securewith original fasteners.13. Connect manifold unions, ignition wire, sen-47
