WARNING: If Common - Ground is > 1 VAC,

STOP: Contact electrician to correct ground failure. Failure to do this may burn out 120V-24V transformer, or may cause other safety control damage or failure.

Attach Manometers to Measure Pressures

•Attach 24" scale manometer to the first main gas shut-off valve pressure tapping.

•Attach one 12" scale manometer to the manifold gas pressure tapping. (See gas valve detail on page 7.)

•Attach one 12" scale manometer to — Pull rubber tube from air pressure switch off the aluminum tubing and connect the manometer using a tee.

Turn Off Main Gas Valve;

Check the Gas Supply Pressure

1.Slowly turn on main gas shut-off valve.

2.Read the gas supply pressure from the manome- ter; minimum supply pressure is 5” W.C., recommended supply is 7” W.C. for natural gas (minimum 11” W.C. for LP gas).

3.If pressure is > 14" W.C., turn off the valve.

4.Check if the service regulator is installed and/or adjust the service regulator.

Start-Up

Blower 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 :

0.5 ± 0.1 in. WC for models 102 and 122.

0.7 ± 0.1 in. WC 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.

Main 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 pres- sure at gas valve manifold pressure tap. (See gas valve detail page 7) This should read 3.5 ± 0.1 in. WC for natural gas or 10.5 ± 0.1 in. WC for LP gas.

6.If the pressure reading differs by more than ± 0.1 in. WC. Remove manifold adjustment screw cover off the pressure regulator on the gas valve, adjust main burner manifold pressure. Replace the man- ifold adjustment screw cap on the gas valve.

Your Hi Delta is tuned in!

Safety Inspection

•Replace main gas manifold adjustment screw cap.

•Check all thermostats and high limit settings.

•During the following safety checks leave manome- ters 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.

•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 in. WC for natural gas and 10 in. WC for LP gas.

•High gas pressure switch (optional) at 1 in. WC above manifold pressure.

•Insert ignition control lockout tests as safety check.
