WARNING

To prevent scalding from DHW recirculation temperature creep, a suitable method to stop recirculation
flow once water in the loop has reached the desired temperature must be used. Failure to stop water
flow once the desired DHW temperature has been reached can result in serious injury or death due to
scalding.

Hydronic piping omitted for clarity.

NOTICE

Note

: Aquastat for DHW

recirculation pump or
thermostatic shut off valve must
be used to stop recirculation
water

fl

ow once the desired

temperature has been reached.

For best performance, Pre-Heat
Mode should be enabled when
using DHW recirculation.

F I R E T U B E C O M B I

WARNING

An ASSE 1070 anti-scald mixing valve is REQUIRED. Failure to comply could result in property
damage, severe injury, or death.
