PRESSURE SWITCH ADJUSTMENT:

FLAME ROLL-OUT SAFETY SWITCH

1.With pump and heater on, turn adjustment knob (clockwise) until a click is heard from the gas valve.

2.Turn adjustment knob (counter clockwise) 1/4 turn.

3.Turn pump off and on several times. Heater should shut off immediately. If it does not, repeat steps above until proper adjustment is made.

The heater is equipped with a thermal cutoff device to prevent flame roll-out in the event the heat exchanger becomes blocked. This is a "Single-use" type fusible link or thermal fuse, that must be replaced when dis- abled by an over temperature condition, caused by excessive restriction in the heat exchanger flue pas- sage.

HIGH LIMITS

The heater is equipped with two automatic high limits. Set to operate at 135°F and 140°F.

NOTE: An erratic high limit is often characteristic of internal heat exchanger problem, i.e. scale buildup, U.G. operation. Refer to troubleshooting section.

NOTE: If heater is installed outside of the limits shown, a flow switch must be used in place of the pressure switch when mounted and wired adjacent to the heater.

TWO SPEED PUMPS

In some cases, the flow on the low-speed is insuf- ficient to operate the heater. This is apparent when the pressure switch cannot be further adjusted or if the heater makes banging noises. In these cases, the pump must be run at high speed when heating the water.

CAUTION: Do not operate the heater without the func- tion of a properly adjusted pressure switch.

HIGH LIMIT REMOVAL

1.Disconnect top portion of unit. (See heat ex- change removal procedure step 1 thru 7 and step 10)

2.Remove defective high limit and replace with new high limit.

3.Reverse above procedure to reinstall.

PILOT SAFETY (Millivolt System)

The heaters equipped with the standing pilot (milli- volt system), have pilot generators which act as a safety device to shut off the flow of gas to the main burners and the pilot burner in case the pilot flame is extinguished. The pilot burner must be manually relighted to place the heater in operation again. Refer to the lighting instruc- tions provided on the heater label.

PILOT SAFETY (IID Units) ELECTRIC IGNITION The heater employs a pilot safety which closes the

main gas valve within 8/10ths of a second whenever the pilot flame is interrupted. Pilot flame is automatically lit when the device is powered. Unit performs its own safety check and opens the main valve only after the pilot is proven to be lit.
