IV. Operating and Service Instructions

A.ALWAYS INSPECT INSTALLATION BEFORE STARTING BURNER.

B.FILL HEATING SYSTEM WITH WATER.

1.Hot Water Boilers: Fill entire Heating System with water and vent air from system. Use the following procedure on a Series Loop System installed as per Figure 9:

a.Close all but one zone valve.

b.Open drain valve on boiler.

c.Open fill valve.

d.Close purge valve.

e.Open relief valve on boiler.

f.Allow water to run out of drain valve until zone has been purged of air and filled with water.

g.Open zone valve to the second zone to be purged, then close the first. Repeat this step until all zones have been purged but always have one zone open. At completion open all zone valves.

h.Close drain valve.

i.When water discharges from relief valve, release the lever on the top of the relief valve, allowing it to close.

j.Continue filling the system until the pressure gauge reads 12 psi. Close fill valve.

C.CHECK CONTROLS, WIRING AND BURNER to be sure that all connections are tight and burner is rigid, that all electrical connections have been completed and fuses installed, and that oil tank is filled and oil lines have been tested.

D.LUBRICATION

1.Follow instruction on burner and circulator label to lubricate, if oil lubricated. Most motors currently used on residential type burners employ permanently lubricated bearings and thus do not require any field lubrication. Water lubricated circulators do not need field lubrication.

2.Do not over-lubricate. This can cause as much trouble as no lubrication at all.

E.ADJUST CONTROL SETTINGS with burner service switch turned “ON”.

1.SET ROOM THERMOSTAT about 10°F below room temperature.

2.On WATER BOILERS WITHOUT TANKLESS HEATERS equipped with L7248 electronic aquastat controller, set High Limit (HL) at 180°F. This temperature can be varied to suit installation requirements. L7248 controller has the High Limit adjustment range from 180°F to 240°F (82°C to

116°C). High Limit Differential is fixed at 15°F

(8°C).

3.On WATER BOILERS WITH TANKLESS HEATERS equipped with L7224 electronic aquastat controller, set operating control (low limit [LL])

at 190°F and high limit (HL) at 210°F. Operating control (low limit) setting must be a minimum of 20°F below high limit setting.

L7224 controller has the High Limit adjustment range from 130°F to 240°F (55°C to 116°C), and the Low Limit adjustment range from 110°F to 220°F (43°C to 104°C). High Limit Differential is fixed at 10°F (6°C), and Low Limit Differential has adjustment range from 10°F (6°C) to 25°F (14°C).

4.ADJUSTING AQUASTAT CONTROLLER SETTINGS. To discourage unauthorized changing of Aquastat settings, a procedure to enter the ADJUSTMENT mode is required. To enter the ADJUSTMENT mode, press the UP, DOWN, and I buttons (refer to Figure 22) simultaneously for three seconds. Press the I button until the feature requiring adjustment is displayed:

•HL_­  High Limit.

•LL_­  Low Limit.

•Ldf  Low Limit Differential.

•°F  °C.

Then, press the UP and/or DOWN buttons to move the set point to the desired value. After 60 seconds without any button inputs, the control will automatically return to the RUN mode.

Note that L7224 Aquastat Controller will display all four (4) above-listed adjustment features, but L7248 Aquastat Controller will not display Low Limit and Low Limit Differential adjustment features.

5.DISPLAY READOUT

In the RUN mode, the Aquastat will flash "bt"

(boiler temp) followed by the temperature (i.e., 220), followed by °F or °C.
