SECTION D: Start up

of the control system and any gas control which has been under water.

•Check around unit for debris and remove combusti- ble products, i.e. gasoline, etc.

Pre Start-up Check

1.Verify heater is filled with water.

2.Check system piping for leaks. If found, repair immediately.

3.Vent air from system. Air in system can interfere with water circulation. If the heater is equipped with the optional air vent, ensure that it is adjusted before firing the heater to make sure all air is vented prior to start-up.

4.Purge air from gas line up to heater.

Initial Start-up

Tools Needed

•(1) 12-0-12, 24” scale U-tube manometer

•(2) 6-0-6, 12” scale U-tube manometer

•(1) Phillips screwdriver

•(1) Crescent wrench

•(1) Multi-meter

•(1) Amp probe

NOTICE: Digital manometers are not recommended.

Preparation

WARNING: Do not turn on gas at this time.

Check Power Supply

With multi-meter at incoming power, check voltage between:

Hot - Common (≈120 VAC)

Hot - Ground (≈120 VAC)

Common - Ground (< 1 VAC)

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

1.Turn off main gas valve.

2.Attach (1) 12” scale manometer to an upstream bleedle valve on the gas supply pipe to the heater (Measure point “A” in Fig. 39).

3.Attach (1) 24” scale manometer to the manifold pressure tap located on the valve (Measure point “C” in Fig. 39).

4.Attach (1) 12” scale manometer near the fan- proving switch. Pull black cap from air pressure switch tee and connect the manometer. NOTE: Re- tain caps for reinstallation later.

Fig. 39: Gas Pressure Measurement Location

Check Gas Supply Pressure

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

2.Read the gas supply pressure from the manometer; minimum supply pressure for natural gas is 4.0 in. WC, recommended supply is 7.0 in. WC, mini- mum supply pressure for propane gas is 4.0 in. WC, recommended supply is 11.0” WC (dynamic readings, full fire input).

3.If the pressure is > 14.0 in. WC, turn off the valve.

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

Start-Up

Blower Adjustment

1.Turn off power.

2.Unplug cap at pressure switch and connect ma- nometer to the tee.

3.Close manual firing valve.

4.Turn power on.
