MAINTENANCE
WARNING
Disconnect all power to the unit before
attempting any service procedures. Contact with
electricity can result in severe injury or death.
11.1 System Maintenance
Do the following once a year:
1. Lubricate all the pumps in the system, per
the instructions on the pump.
2. Inspect the venting system for obstruction
or leakage. Periodically clean the screens
in the vent terminal and combustion air
terminal (when used).
3. Keep the area around the unit clear and
free of combustible materials, gasoline, or
other flammable vapors or liquids.
4. If the unit is not going to be used for
extended periods in locations where
freezing normally occurs, it should be
isolated from the system and completely
drained of all water.
5. Low water cutoffs, if installed, should be
checked every year. Float type low water
cutoffs should be flushed periodically.
6. Inspect and clean the condensate
collection, float switch and disposal system
yearly.
7. When a means is provided to neutralize
condensate, ensure that the condensate is
being neutralized properly.
8. Inspect the flue passages, and clean them
using brushes or vacuums, if necessary.
Sooting in flue passages indicates
improper combustion. Determine the
cause of the problem and correct it.
9. Inspect the vent system and air intake
system, and ensure that all joints are
sealed properly. If any joints need to
be resealed, completely remove the
existing sealing material, and clean with
alcohol. Apply new sealing material, and
reassemble.
10. Once a year, the items listed below
should be inspected by a qualified service
technician:
a. Appliance control f. Flow switch
b. Automatic gas valve g. Low water
cutoff
c. Pressure switches h. Burner
d. Blower i. Heat exchanger
e. Pump j. Ignitor
Do the following once every six months:
1. If a strainer is employed in a pressure
reducing valve or the piping, clean it every
six months.
11.2 Maintenance Notes
Use only genuine Bradford White replacement parts.
Caution
When servicing the controls, label all wires be-
fore disconnecting them. Wiring errors can cause
improper and dangerous operation. Verify proper
operation after servicing.
The gas and electric controls in the MagnaTech
are engineered for long life and dependable
operation, but the safety of the equipment
depends on their proper functioning.
11.2.1 Burner
Check the burner for debris. Remove the blower
assembly to access the blower adapter plate.
Remove the 4 bolts connecting the blower to
the arm. Remove the 5blower adapter plate
to access the burner. Pull the burner up and
out. Clean the burner, if necessary, by blowing
compressed air from the outside of the burner
into the center of the burner, and wipe the
inside of the burner clean with glass cleaner. A
dirty burner may be an indication of improper
combustion or dirty combustion air. Determine
the cause of the problem, and correct it. If the
burner gaskets are damaged, replace them
when replacing the burner.
11.2.2 Modulating Gas Valve/ Venturi
The modulating gas valve consists of a valve
body that incorporates the On/Off gas flow
control and a negative pressure regulator. It
provides the air/gas ratio control in combination
