Start-up — if boiler doesn’t start . . .VIIe
Start-up — operate boiler (cont.)VIId
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.
Check for:
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.
