3.0START-UP

3.1Blower Adjustment

1.Disconnect fan pressure switch tubing at plenum and connect manometer using a tee.

2.Close all manual firing valves.

3.Turn power on;

4.Check manometers attached to fan pressure switch. The readings should be :

.5 + .1” W.C. for models 102 and 122

.7 + .1” W.C. for models 202, 242, 322

If not, adjust the air shutter on the blower to attain the correct value. (See air shutter adjustment page 7)

5.Turn power off.

6.Reconnect fan pressure switch tubing to original position.

3.2Main Burner Adjustment

1.Turn off unit.

2.Open manual firing valve.

3.Turn on the unit, wait 15 seconds, and the igniter should glow. Sight glass to check igniter at both ends of the heater. Gas valve should be open after 45 seconds.

4.If burner does not light on first trial. It will retry, up to 3 times

5.Main burner ignition – check manifold gas pressure at gas valve manifold pressure tap. (See gas valve detail page 7) This should read 3.5 + .1” W.C. for natural gas or 10.5 + .1” W.C. for LP gas.

6.If the pressure reading differs by more than + .1" W.C. Remove manifold adjustment screw cover off the pressure regulator on the gas valve, adjust main burner manifold pressure. Replace the manifold adjustment screw cap on the gas valve.

3.3Safety Inspection

•Replace main gas manifold adjustment screw cap.

•Check all thermostats and high limit settings.

•During the following safety checks leave manometers hooked up, check and record.

•If other gas fired equipment are in the room and on same gas main check all pressures on the Hi Delta with all other equipment running.

Remember, incoming gas pressure could be lower than specified on page 19, provided 3.2.5 is met.

•Check thermostats for ON/OFF operation.

•Check High limits for ON/OFF operation.

•While in operation, check flow switch operation

•Check the low gas pressure switches (For proper adjustment, if available, use the attached manometers to set pressure. The scales on the switch are approximate only ); Low gas pressure switch must be set at 5" W.C. for natural gas and 10” W.C. for LP gas.

•High gas pressure switch (optional) at 1" W.C. above manifold pressure.

•Insert ignition control lockout tests as safety check.

3.4Follow-Up

•Safety checks must be recorded as performed.

•Turn unit on.

After main burner ignition:

•Check Manometer for proper reading.

•Cycle unit several times and recheck readings

•Reanalyze with unit running record or print results.

•Remove all Manometers and replace hose, remove jumper, replace all gas pressure caps.

•Check for gas leaks one more time.
