MEASURING THE OUTCOMING WATER TEMPERATURE, CON’T
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
similar to 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.
MAINTENANCE
Annual service of the BCS is suggested and biannual service is recommended. For
burner maintenance, follow the manufacturer’s instructions supplied with the burner.
1. Install a new burner nozzle of the correct rate and angle.
2. Clean and adjust the electrodes and inspect for cracks in the porcelain. Check for corro-
sion on the buss bars and ignitor terminals.
3. Change the fuel oil filter and have the oil tank checked for sediment. Clean the tank, if
necessary.
4. The system should be checked with combustion instruments for safe and efficient
operation.
5. Keep the oil tank full to prevent water vapor from collecting (especially during the
summer).
6. Regularly check the Balanced Flue for obstructions such as hornets’ nests. The end caps
are removable for cleaning. Check the inlet and outlet tubes for any blockage and make
sure the joints are sealed.
7. EVERY SIX TO 12 MONTHS: Drain the heater tank and inspect for sediment or lime accu-
mulation. Flush if necessary. If lime has accumulated, remove with a commercial com-
pound. Check your water softening equipment if lime is found. DO NOT ATTEMPT TO
HEAT HARD WATER. (See maintenance 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.) It is recommended that
your 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. Make sure it reseats itself.
10. If the heater is shut off in cold weather, drain the tank to prevent freezing.
