Installation, Start-Up, Adjustment and Maintenance Manual

1.
Turn main gas valve
knob to the “OFF” position.
2.
Remove the plug on outlet end of gas valve (see Figure 24) and attach pressure tap and
manometer.
3.
Turn power “ON,” and close control switch.
4.
Wait for the burner to start up. Due to the presence of air inside the piping, it may be that the
burner does not start at the first three attempts and failing to do so the ignition system is
locked out. If this happens reset the ignition system by opening the control switch for 5
minutes and then re-closing. Repeat until all the air is purged from the piping and the burner
ignites.
5.
When the burner ignites read the manometer and compare to the required pressure in Table
12.
6.
If necessary change the manifold pressure using the gas valve regulator. The regulator is
built into the gas valve. Remove the seal screw and turn adjusting screw clockwise to
increase pressure or counter clockwise to reduce pressure. Replace seal screw after
adjustment.
7.
Open control switch and make sure unit is off.
8.
Remove manometer and pressure tap. Replace plug in gas valve.
9.
Turn unit on by closing control switch. Check all gas connections with soap for leaks.

6.4 USED OIL BURNER ADJUSTMENTS
1.
IMPORTANT-
Prior to starting the unit, pre-fill the filter and fuel line with oil to assist priming
procedure. Oil pump motor turns at low RPM’s and would take significant time to complete
priming process if not pre-filled.
2.
Making sure the thermostat is turned off, apply power to the Chiller unit. Switch burner main
power switch to ON position. After allowing the oil pre-heater time to establish temperature
setpoint, approximately 5 minutes. Jump the “T” terminals on the Oil Primary (Figure 25).
Once the burner is running,
temporarily jump the “F” terminals on the Oil Primary. This will
allow the burner to run during the pump priming process.
3.
Priming the oil pump: Open bleeder valve one turn until all air is expelled (Figure 28). This
may need to be done twice to insure all air is removed.
IMPORTANT:
When fully purged and
flame is est
ablished remove temporarily jumpers on “F” and “T” terminals of the Oil Primary to
allow safety features of the unit to operate properly.
4.
Adjust air supply of integrated air compressor to 12 - 13 P.S.I. This is factory preset,
however, due to freight handling settings may be compromised.
5.
Adjust oil pump motor speed at adjuster post to reed 1.5 PSI on the oil gauge located on the
burner.
