Vent Switch Adjustment:
In order to ensure proper operation of the ADB boiler
with a CHX attached to it, the vent switch must be
adjusted to proper setting. The vent switch is located
on the J-box, just outside the ignition module. Use the
following steps:
• Turn power off; disconnect the electrical wiring
and the rubber hose.
•
Remove the switch (it has a black plastic orifice at
the hose connection).
•
On the backside, remove the (purple) seal from
atop the adjusting screw.
•
Turn the plastic hex screw 1-1/2 turn clockwise.
•
Seal with silicone.
•
Reinstall in reverse order.
