VIId Start-up — operate boiler (cont.)

Figure 19 Check for igniter glow by looking into observation port on front of blower housing.

Observation port

2.Vent air from system using manual vents. Air in the system will interfere with circulation and cause heat distribution problems and noise.

3.Inspect vent system thoroughly. Check for gas- tight seal at every connection and seam.

4.Check around the boiler for gas odor following the procedure of Section VIIb of this manual.

If you discover evidence of any gas leak, shut down the boiler at once. Find the leak source with bubble test and repair immediately. Do not start boiler again until corrected. Failure to comply could result in severe personal injury, death or substantial property damage.

5.Verify igniter operation — Look through blower observation port (see Figure 19). Access the blower by removing the boiler jacket front panel.

You should see the igniter glow, particularly during the igniter warm-up period of the control cycle.

6.After successful operation of boiler and verification of system (water, vent and gas piping), proceed to the Check-out procedure, Section VIII of this manual.

VIIe Start-up — if boiler doesn’t start . . .

Check for: 1. Loose connections, blown fuse or service switch off?

2.High limit switch set below boiler water temperature?

3.Thermostat set below room temperature?

4.Gas not turned on at meter or boiler?

5.Incoming gas pressure less than 4" w.c.?

If none of the above corrects the problem, refer to

Troubleshooting, manual Section XI.
