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, 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.

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.
