TURBOPOWER 99 WATER HEATER
18.If the burner fails to light, the flame control will lockout. When this happens press the reset button on the front of the control to recycle burner.
19.Once the main burner flame is established the firing rate will be controlled by the TempTrac control.
20.While the unit is running, verify the inlet gas pressure is within the range shown in the “GAS SUPPLY AND PIPING” section of this manual.
21.Burner Combustion Adjustment. Burner combustion should only be adjusted using a combustion analyzer. Do not attempt to adjust burner by sound or sight. With the burner firing, insert the combustion analyzer probe in the flue vent approximately two feet from the appliance. Adjust to obtain the desired O2 and CO2 in the combustion products.
22.Perform flue gas analysis while the stored water is near the desired temperature and unit is in stable operation (after running about 2 to 5 minutes):
Net stack temperature should be 10ºF to 40ºF (Maximum 160ºF)
O2 should be from 3% to 5%. (target 4%)
CO2 should be from 9% to 10% (target 9½%)
CO should not exceed 200 PPM
IMPORTANT: If the appliance is to be shut down for an extended period of time, the primary gas valve and the water supply should be shut off. When the appliance is returned to service, a thorough inspection of all utilities and general appliance condition should be conducted.
14PERIODIC MAINTENANCE
Listed below are items that must be checked to insure safe reliable operations. Maintenance must be performed by a qualified service or maintenance provider. Verify proper operation after servicing.
WARNING: When servicing the controls, use exact, factory authorized, replacement parts and label all wires prior to disconnection. Verify proper operation after servicing. Incorrect parts substitution and wiring errors can cause damage, improper operation, fire, carbon monoxide and other unexpected and unsafe conditions that could result in fire, injury or death.
1.Examine the appliance and venting system at least once a year. Check more often in first year to determine inspection interval:
a.Check all joints and pipe connections for tightness, corrosion or deterioration.
b.Check the
c.Check all safety controls including thermostats for proper operation.
d.Check safety
e.Have the entire system, including, but not limited to, the burner, heat exchanger and venting system, periodically inspected by a qualified service agency.
2.Any sign of soot in the burner or in the flue indicates the need for a combustion inspection. If soot has formed, the most common causes are restricted combustion air or excessive gas. A blocked heat exchanger can cause unsafe operation and will reduce efficiency. Contact a qualified serviceman or installer to inspect and clean the heat exchanger or vent.
3.Inspect low water cutoffs and relief valves for proper operation at every six months, or more often if indicated by inspection.
4.Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.
5.Check frequently to be sure the flow of combustion and ventilation air is unobstructed to the appliance.
6.If the appliance is to be shut down for an extended period of time, the primary gas valve and the water supply should be shut off. When the appliance is returned to service, a thorough inspection of all utilities and general appliance condition should be conducted.
