CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.2.

Determining Product Location

NOTICE
The EXALT is certified for indoor,
conditioned space installations ONLY.
Before locating the EXALT check for convenient
locations to:
• Heating system piping
• Venting
• Gas supply piping
• Electrical service
Ensure the EXALT location allows the combustion air/
vent piping to be routed directly through the building
and terminate properly outside with a minimum amount
of length and bends.
Ensure the area chosen for the installation of the EXALT
is free of any combustible materials, gasoline, or other
flammable liquids.
WARNING
Failure to remove or maintain the area free
of combustible materials, gasoline, or other
flammable liquids or vapors can result in
substantial property damage, serious injury,
or death.
Ensure the EXALT and its controls are protected from
dripping or spraying water during normal operation or
service.
The EXALT should be installed in a location so that any
water leaking from the boiler, piping connections, or
relief valve will not cause damage to the surrounding
area or any lower floors in the structure.

Boiler Freeze Protection Feature

The CTRLMax boiler management system has a freeze
protection feature built in. This feature monitors the
boiler water temperature and responds as follows when
no call for heat is present:
• 46ºF [8ºC] Pump outputs configured to respond to
a CH1 Call are enabled.
• 42ºF [6ºC] Pump outputs configured to respond to
a CH1 or CH2 Call are enabled, Burner operates at
low fire.
• 60ºF [15ºC] Freeze protection ends. Burner & all pumps
turn off after completing CH Post Pump Time.
CAUTION
• The boiler freeze protection feature is
disabled during a hard lockout. The burner
will not fire, but the circulators will operate.
• The boiler freeze protection feature is
designed to protect the boiler, not the
heating system. The boiler should be
installed in a primary/secondary piping
arrangement if it is installed in an unheated
space or exposed to water temperatures of
46ºF or less. Refer to Chapter 4 for primary/
secondary piping and Chapter 10 for
antifreeze guides.
• Failure to comply can result in minor
property damage, or injury.
1.4.

Boiler Replacement

If the EXALT is replacing an existing boiler, the following
items should be checked and corrected prior to
installation:
• Boiler piping leaks and corrosion.
• Proper location and sizing of the expansion
tank on the boiler heating loop.
• The existing vent system is appropriate for the
EXALT and it is correctly installed. Refer to the
EXALT Vent Supplement for the vent system
requirements.
• Amount and quality of propylene glycol within
the system, if applicable.
