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 to at least 82°C (180°F)
while circulating water in the system.
C. Vent air and add water as needed to achieve
operating pressure on boiler gauge. Pressure must
be between approximately 83 kPa (12 psi) (cold
water) and 172 kPa (25 psi) at water temperature
setting of high limit control, for boilers equipped with
207 kPa (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 35 kPa (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. Viewing and Changing Temperatures:
Setting boiler supply water temperature and DHW
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 32°–85°C (90°–185°F.)
2. While “d” is blinking, boiler supply water
temperature for DHW may be set to desired
temperature. The setting range is between
40°–85°C (104°–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
32°–71°C (90°–160°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. Priority for either space heating or DHW may be
chosen, with a selectable time limit or infinite
operation.
4. Weather compensation slope and set point
temperature may be changed (if outside sensor
is used). (See Figure 24 for graph).
5. Read actual blower RPM.
6. Adjust blower RPM for high and low input
adjustment.
7. Read flame current in micro amp.
8. 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
“Viewing and Changing Temperatures” and
“Viewing and Changing System Setting” menus.
3. Enter - Used to store values that are changed in
the “Viewing and Changing Temperatures” and
“Viewing and Changing System Setting” menus.
4. Up- Used to increase values in the “Viewing and
Changing Temperatures” and “Viewing and
Changing System Setting” menus.
5. Down - Used to decrease values in the “Viewing
and Changing Temperatures” and “Viewing and
Changing System Setting” menus.
