OPERATING INSTRUCTIONS

I.FILLING AND VENTING WATER SYSTEMS

A.Fill the system with water. Vent or purge of air.

B.Fire the boiler as soon as possible (see following warning and instructions) and bring water temperature in the system.

C.Vent air and add water as needed to achieve operating pressure on boiler gauge. Pressure must be between approximately 12 psi (cold water) and 25 psi at water temperature setting of high limit control, for boilers equipped with 30 psi relief valves. Boilers rated for a higher pressure and equipped with a matching relief valve may operate at a higher pressure, but no higher than 5 psi below the relief valve opening pressure.

D.Check for and repair any leaks before placing system in service.

BEFORE FIRING BOILER, make these checks:

Before firing boiler, review the “Boiler Control and Display Features” section of this manual. Understanding the features and programming the applicable parameters is essential for setting up the boiler to operate properly on the heating system it is installed on.

1.System is full of water. Air is vented or purged.

2.Relief valve is installed in accordance with ASME Boiler and Pressure Vessel Code, Section IV. Valve opening is not closed or reduced in size.

3.Venting is installed according to instructions under “FLUE

GAS VENTING REQUIREMENTS”.

4.All wiring is completed, following applicable wiring diagrams.

5.Using soap solution, check for gas leaks in all gas piping from meter to boiler gas supply pipe. DO NOT use open flame.

II.BOILER CONTROL AND DISPLAY FEATURES (See Figure 23)

A. Boiler Operation Status:

“Mode Display” shows status of boiler operation (see table 3).

B. View and Changing Temperatures:

Setting boiler supply water temperature and water tank temperature (see table 4).

Press “Select” button for viewing following different modes on “Mode Display”

1.While “c” is blinking, boiler supply water temperature for space heating may be set to desired temperature The setting range is between 90˚ to 185˚F.

2.While “d” is blinking, boiler supply water temperature for DHW may be set to desired temperature. The setting range is between 104˚ to 185˚F.

3.While “t” is blinking, DHW tank temperature may be set to desired temperature (if tank is equipped with sensor). The setting range is between 104˚ to 185˚F.

4.View actual boiler supply & return water tempera- ture, domestic hot water tank temperature (if tank equipped with sensor), flue temperature and outside temperature (if outside sensor is used) on “Temperature Display” by selecting 1, 2, 3, 4, or 5 on “Mode Display”.

These numbers are steady on display and are not settable.

All sensor inputs to the control must be connected to a 12k ohm sensor.

C.Viewing and changing system setting:

A trained, experienced service technician or installer should perform following adjustments. See table 5 for details.

1.Space heating and DHW post pump time may be changed.

2.Space heating and DHW modes may be chosen.

3.Weather compensation slope and set point temperature may be changed (if outside sensor is used).

(See Figure 23 for graph).

4.Read actual blower RPM

5.Adjust blower RPM for high and low input adjustment.

6.Read flame current in micro amp.

7.Run boiler on high, low or ignition input steady for 20 minutes for test purposes.

D.Display and push buttons:

1.Reset - Used to clear a Lock out error (indicated with an “A” in the “Mode Display”).

2.Select - Used to scroll through the modes in the “View and Changing Temperatures” and “Viewing and Changing System Setting” menus.

3.Enter - Used to store values that are changed in the “View and Changing Temperatures” and “Viewing and Changing System Setting” menus.

4.Up- Used to increase values in the “View and Changing Temperatures” and “Viewing and Changing System Setting” menus.

5.Down - Used to decrease values in the “View and Changing Temperatures” and “Viewing and Changing System Setting” menus.
