Boiler Air Vent
NOTICE
This boiler is supplied with a special automatic air
vent that will provide reliable operation in purging
air from the boiler. The hygroscopic cap supplied
with the automatic air vent MUST remain tight at
all times on the air vent body. The hygroscopic cap
has a membrane which expands upon contact with
water and seals the air vent until the membrane
dries up due to new air forming in the air vent.
1.
Make sure to fully tighten the cap on the air vent
during initial installation.
2.
Never loosen the hygroscopic cap to allow air to escape
the air vent. Air will exit with the cap fully tightened in
place.
3.
If the hygroscopic cap is not fully tightened, water
may leak from the cap. Simply tighten the cap se-
curely.

Low Water Cutoff Device
•
The INSTINCT is equipped with a factory installed
pressure sensor type Low Water Cut Off (LWCO).
•
The minimum operating system pressure is 7 psi.
In the event that the pressure falls below 7 psi the
burner will deactivate until proper pressure has
been restored.
•
Check local codes if a Low Water Cutoff is required.

NOTICE
The INSTINCT control system also senses the water
temperatures entering and exiting the heat exchanger
to provide protection against low water conditions.
Where local codes and jurisdiction do not accept
a pressure device for low water protection, the
jurisdiction may accept this INSTINCT integral control
function as a means of providing low water protection.
