A. COMPLETING THE INSTALLATION
1. Confirm that all water, gas and electricity are
turned off.
2. Verify that water piping, venting, gas piping and
electrical wiring and components are installed
properly and where applicable in accordance with
manufacturers' instructions. Be sure that the boiler is
installed in accordance with this manual and good
engineering practice.
3. Fill the boiler and system with water, making certain
to vent all air from each high point in the system.
Open each vent in the system until all air is released
and water begins to be discharged, and then close
the vent.
4. The pressure reducing valve on the fill line will
typically allow the system to be filled and pressurized
to 12 PSI. Consult the manufacturer's instructions for
operation of the valve and expansion tank.
5. Check joints and fittings throughout the system and
repair as required.
6. Connect a manometer at or near the service valve to
the boiler.
7. Confirm that the gas supply pressure to the boiler is
between the minimum and maximum values for the
gas being used. These values can be found in Table
4.4 of Section 4.
8. If a full supply pressure test is required, isolate the
boiler and gas valve before performing the pressure
test. If the supply pressure is too high or too low,
contact the fuel gas supplier.
9. Turn on electricity and gas to the boiler. Check to see
if the LED display is lit. The combustion air fan will
begin a 5 second purge cycle and then the control
will go into Standby Mode.
10. Adjust set point temperatures and differential
temperatures by pressing and holding the S3,
"Program" key for 3 seconds.
a) The control will enter the Supply Set Point
selection.
b) The display will alternately show "C" and then
the current set point temperature.
c) The set point may be adjusted by using the S1/-
(to decrease) or S2/+ (to increase) keys on the
display module.
d) Pressing the S3 "Program" key again will advance
to the next adjustable value, Set Point Differential
and the display will alternate between.
e) The differential adjustment is the difference
between the temperature at which the boiler
shuts down (high) and the temperature at which
it re-starts (low).
f) The differential may be set to values between 5°F
(3°C) and 30°F (17°C) in 1°F increments.
g) The boiler will always shut down at a
temperature 7°F (4°C) above the set point. The
differential temperature is then applied to this
value.
h) The set point differential may be adjusted by
using the S1/- (to decrease) or S2/+ (to increase)
keys on the display module.
i) Pressing the S3 "Program" key again will advance
to the next adjustable value. The display will read
"de" and alternate with numerical value. This
value is not applicable to the Pinnacle boiler.
j) Finally, by pressing the S3 "Program" key again,
the display will advance to the Measurement
Units selection. The display will alternate
between "t" and either "F" or "C" depending on
the units selected. This value may be changed by
using the S1/- or S2/+ keys on the display
module.
11. Light the boiler by following the Lighting/Operating
instructions in this section. The initial ignition may
fail several times before the gas piping is completely
purged of air.
12. Use the sequence of operation description and
Figure 6.3, Control Board Wiring Schematic to
follow light off and shutdown sequences and to assist
in diagnosing problems. If the boiler does not
function properly, consult Section 8,
Troubleshooting.
