ODS (Oxygen Depletion
Sensor) and Valve
Components
It may also be necessary to replace the
ODS and valve components. In order
to do this, the control bracket assembly
must be removed. To do this complete
the above steps 1-10 to remove the
main burner assembly and then refer to
the following steps:
1.
Remove (2) screws connecting the
control bracket to the main body of
the heater. See Figure 10.
2.
Remove the valve knob by pulling it
away from the heater.
3.
Use a 9/16” (or 14 mm) wrench
to remove the compression nut
connecting the inlet gas tube to the
enclosure. See Figure 11.
4. Lift up on the control bracket assembly
to remove it from the heater. See
Figure 12.
5. Complete the following steps where
necessary to replace the various
components on the control bracket
sub-assembly (Refer to Figure 13):
•
To remove the pilot gas tube, unscrew
the compression nuts with a 7/16” (or
12 mm) wrench.
•
To remove the burner gas tube or the
inlet gas tube, use a 9/16” (or 14 mm)
wrench.
•
To remove the Valve, ODS, or Tip
Switch, remove the screws connecting
them to the control bracket. Remove
thermocouple and ignition wires
where necessary.
6. Replace components as needed and
reassemble. Be sure to check gas
connections with a mild soap water
solution upon lighting.
