SECTION D: Start up

5.Check blower motor amp draw and the manometer attached to fan pressure switch with the blower running at 100% speed. The reading should be as noted in Tables P and Q for both natural gas and propane gas. If not, adjust the air shutter on the blower to attain the correct values.

6.Measure the blower amp draw and compare the measured values to the values in Table P. If the measured value is different than the values in the table (with the noted tolerance), contact the factory.

NOTE: Connect the amp probe to the 14 Ga. black power wire going into the blower.

7.Turn power off.

8.Disconnect the manometer and reconnect the cap.

Manifold Adjustment

1.Turn off unit.

2.Open manual firing valves.

3.Turn on the unit, wait approximately 15 seconds, and the igniter should glow (observable through the observation port located at the front, bottom of the heater). Look into sight glass located at the bottom of the front panel to check igniter operation. Gas valve should open in 45-60 seconds.

4.If burner does not light on first trial. It will go into lockout with the standard ignition module. If it is equipped with the optional 3-try ignition module, it will try for ignition up to three times.

5.Main burner ignition: Check manifold gas pressure at gas valve outlet pressure tap (connection “C” in Fig. 39). This should read per the values in Table R for natural gas and propane gas.

6.If the pressure reading differs by more than ± 0.2 in. WC, STOP – Call the factory for directions on what to do next!

CAUTION: Special manifold and air settings may be required.
