START-UP PROCEDURES
7. START-UP PROCEDURES
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
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.
