Smith BTF-80 SERIES 210 water heater troubleshooting

PROBLEMPOSSIBLE CAUSE(S)CORRECTIVE ACTION
BURNER FLAME TOO HIGH1. Air inlets blocked1. Unblock inlet air openings
2. Insufficient secondary air2. Provide ventilation to water heater
3. Orifice too large3. Replace with correct orifice
FLAME BURNS AT ORIFICE1. Low gas pressure1. Check with gas utility company
2. Defective gas control valve/thermostat2. Replace gas control valve/thermostat
INSUFFICIENT HOT WATER1. Low gas pressure1. Check with gas utility company
2. Orifice too small2. Replace with correct orifice (see rating plate)
3. Thermostat set too low3. Turn temperature knob to higher setting
4. Gas control error codes4. Refer to gas control error codes
5. Sediment or lime in tank5. Drain/flush-provide water treatment if needed
6. Water heater too small6. Install adequate heater
7. Wrong piping connections7. Correct piping: dip tube must be in cold inlet
8. Leaking faucets8. Repair faucets
9. Wasted hot water9. Advise customer
10. Long runs of exposed piping10. Insulate piping
11. Hot-water piping in outside wall11. Insulate piping
WATER IS TOO HOT1. Thermostat is set too high1. Turn temperature knob to lower setting
2. Defective gas control valve/thermostat2. Replace the gas control valve/ thermostat
SLOW HOT WATER RECOVERY1. Insufficient air/ flue blockage1. Provide ventilation to water heater. Check flue way. flue baffle and burner
2. Low gas pressure2. Check with gas utility company
3. Orifice too small3. Replace with correct orifice (see rating plate)
4. Thermostat set too low4. Turn temperature knob to higher setting
5. Heater too small5. Install adequate heater
6. Wrong piping connection6. Correct piping-dip tube must be in cold inlet
7. Wasted hot water7. Advise customer
8. Flue clogged8. Clean flue, locate source and correct
9. Air inlets blocked9. Unblock inlet air openings
DRIP FROM RELIEF VALVE1. Pressure build-up1. Use a pressure-reducing valve and relief valve
2. Heater stacking2. Lower the thermostat setting
3. Closed water system3. See “Thermal Expansion" section
4. Improperly seated valve4. Check Relief valve for proper operation (Do Not plug T&P valve)
GAS CONTROL VALVE/ THERMOSTAT FAILS TO SHUT OFF1. Defective gas control valve/thermostat1. Replace gas control valve/thermostat
SMELLY WATER1. Sulfides in water supply1. Chlorination procedure
2. Bacteria in water supply2. Chlorination procedure
3. Incompatible anode3. Replace with anode appropriate for water conditions
CONDENSATION1. Filling the new water heater for the first time1. Normal operation: the condensation should disappear after heater warms up
2. Moisture from the products of combustion2. Normal operation: the condensation should disappear in time
3. Water dripping from blower assembly3. Install condensate hose to drain port on the rubber coupling
4. Undersized water heater4. Install adequate heater
COMBUSTION ODOURS1. Air inlets blocked1. Unblock inlet air openings
2. Insufficient air2. Provide fresh air ventilation to the water heater
3. Flue clogged3. Clean, locate source and correct
4. Heater installed in a confined area4. Provide fresh air ventilation to the water heater
5. House too tight5. Provide fresh air ventilation to the water heater
SMOKING AND CARBON FORMATION1. Air inlets blocked1. Unblock inlet air openings
2. Insufficient air2. Provide ventilation to water heater. Check flue way. flue baffle and burner
3. Low gas pressure3. Check with gas utility company
4. Orifice too large4. Replace with correct orifice (see rating plate)
5. Flue clogged5. Clean, locate source and correct
6. Defective gas control valve/thermostat6. Replace gas control valve/thermostat
7. Heater installed in a confined area7. Provide fresh air ventilation
UNABLE TO LIGHT THE BURNER1. Air in gas line1. Purge the air from gas line
2. Pressure switch2. Check the pressure switch, make sure the pressure switch hose is not kinked
3. Blocked exhaust3. Check vent pipe for blockage
4. Wire connection4. Check wire connections
5. Defective gas control valve/thermostat5. Replace the gas control valve thermostat
SIZZLING, RUMBLING NOISE1. Scale and sediment1. Drain/flush-provide water treatment if needed
2. Condensation dripping on burner2. Refer to ‘Condensate" section
WATER LEAKAGE1. Condensation1. Refer to “Condensate" section
2. Dripping Temperature & Pressure Relief Valve2. Refer to “Temperature-Pressure Relief Valve" section
3. Drain valve dripping/leaking3. Back flush to clean- out sediment, replace if necessary.
4. Tank Leak4. Check “Leakage Checkpoints"
BLOWER WILL NOT START1. No power to unit1. Plug in power cord, check fuses and/or supply voltage
2. Thermostat set too low2. Turn temperature knob to higher setting
3. Defective air pressure switch3. Replace air pressure switch
4. Defective blower4. Replace blower
5. Disconnected or loose wire5. Repair and reconnect wires
6. Control locked out6. Refer to “Resetting The Heater Control" - determine cause of lockout
