Temperature Adjustment, Table B | Lochinvar EB-EWU-02, 150 instruction

f.Carefully reinstall combustion chamber door, jacket panels, dividers, burners, manifolds wires and hoses. Use new gasket material for proper air seal.

g.Reassemble and test for gas leaks.

h.Cycle appliance and check for proper operation.

An appliance installed in a dust or dirt contaminated atmosphere will require cleaning of the burners on a 3 to 6 month schedule or more often, based on severity of contamination. Contaminants can be drawn in with the combustion air. Non-combustible particulate matter such as dust, dirt, concrete dust or dry wall dust can block burner ports and cause non-warrantable failure Use extreme care when operating an appliance for temporary heat during new construction. The burners and fan will probably require a thorough cleaning before the appliance is placed in service.

6.Combustion Air Fan: The combustion air fan should be checked every 6 months. Clean as required when installed in a dust or dirt contaminated location.

7.Water Circulating Pump: Inspect pump every 6 months and oil as necessary. Use SAE 30 non-detergent oil or lubricant specified by pump manufacturer.

8.Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

9.Check frequently to be sure the flow of combustion and ventilation air to the boiler is not obstructed.

TEMPERATURE ADJUSTMENT

Operating Temperature Control

NOTE:

The temperature controller is pre-set at the factory with test settings. You may need to adjust the settings to meet your specific needs.

WARNING

Return water temperatures must not be less than 140°F. If lower return water temperatures are required, follow the instructions in the Low Temperature Bypass Requirements or Three-Way Valves section(s) in the Installation and Service Manual.

Locating Temperature Control

Remove the control panel door on the front of the appliance in order to locate and access the temperature control.

Temperature Control Settings

There are three setting knobs on the temperature control unless your appliance is specified as a boiler only with an outdoor air reset option. If your appliance is a boiler only with an outdoor air reset option, there are additional controls for this option. They are explained under Outdoor Air Reset Option, page 7.

The three setting knobs on the temperature control are for Set point, Differential, and High-Fire Offset (see Figure 5).

FIG. 5 Temperature Control

Maximum Set Point Determination

The maximum set point for the control is factory set. Boilers can be set to 240°F max., water heaters are set to 190°F max., and specialty state and local codes to 200°F.

These maximum set points are established by cutting the OJ1 and OJ2 jumpers located on the right side of the temperature controller. The maximum set point is determined as shown below in TABLE-B.

TABLE B

Maximum Set point Determination

		Max.
OJ1	OJ2	Set Point
Connected	Connected	240°F
Cut	Connected	190°F
Connected	Cut	200°F
Cut	Cut	160°F

NOTE:

Anytime that OJ1 is the only jumper cut, a new overlay is required under the Set Point knob on the temperature controller because the scale has changed to a maximum of 190°F.

Anytime the OJ2 jumper is cut (with or without OJ1), a new overlay is required under the Set Point knob on the temperature controller because the scale has changed to a maximum of 200°F.
