MEASURING THE OUTCOMING WATER TEMPERATURE

MAINTENANCE Have the oil burner serviced once each year by a qualified oil burner service person. Service should comply with the burner manufac- turer’s recommenda- tions and include:

– 6 –

5.While the burner is operating, disconnect one of the yellow cad cell wires. Check to see that the burner control locks out in the time specified on the control. Reattach the wire and reset the control. The burner should restart. Note: You may have to wait a minute before resetting the control.

6.The thermostat is factory set at 120°F for residential use. (See caution on page

1regarding temperature variations. It is the responsibility of the homeowner and installer to verify that the installer follows the recommended quantitative testing for measuring the outcoming water temperature. To make sure that the system works properly after installation and in the future, it is recommended that the heater’s performance be measured and monitored. Run water out of the tap near- est the heater until it comes out warm. Using a calibrated thermometer, take a measurement. If the water is not at a suitable temperature for the installation, have a qualified service person adjust the aquastat. Contact Bock for further information on the thermometer if needed.

WARNING: Hydrogen gas can be produced in a hot water system served by a heater that has not been used for a long period of time (generally two weeks or more.) Hydrogen gas is extremely flammable. To reduce the risk of injury, open the hot water faucet at the highest location in the house for several minutes before using any electrical appliance connected to the hot water system. If hydrogen is present, there may be an unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or allow an open flame near the faucet at the time it is open.

1.Oil the burner motor (5-10 drops) with #10 SAE motor oil (if applicable).

2.Install a new burner nozzle of the correct rate and angle. (See Chart A, page 11).

3.Clean and adjust the electrodes and inspect for cracks in the porcelain. Check for corrosion on the buss bars and ignitor terminals.

4.Change the fuel oil filter and have the oil tank checked for sediment. Clean the tank if necessary.

5.Keep the oil tank full to prevent water vapor from collecting inside the tank, especially during the summer.

6.Check the smoke pipe and chimney. Clean and repair if necessary.

7.EVERY SIX to 12 MONTHS. Drain water from the heater tank and inspect for sediment or lime accumulation. Flush out if necessary. If lime has accumulated, remove with a commercial compound for dissolving lime or by scraping through the hand hole opening (if supplied). Check water softening equipment if lime is found in the tank. DO NOT ATTEMPT TO HEAT HARD WATER. (See mainte- nance label on heater.)

8.Change the magnesium anode rods every six to 12 months or when they are reduced to 3/8” diameter (see maintenance label on heater). We recom- mend the installer use PermaBond LH-050. Teflon tape should not be used when installing magnesium or aluminum anode rods.

9.Open the relief valve test lever to flush out the tank. Make sure it reseats itself.

10.If the heater is to be shut off in cold weather, drain the tank to prevent freezing.
