This boiler must have adequate water flowing through it
whenever the burner is on. Failure to do this will damage
the unit and void the warranty.

Caution
The Trinity is tested with Natural Gas having a
heating value of 1020 BTU per cubic foot. For
areas with lower heating values, a combustion
test is required to obtain optimum operation.
Warning for all Systems
All systems must be flushed to remove sediment, flux,
filings, etc. Failure to do so will seriously damage the
boiler, voiding warranty. (Recommend using Fernox
cleaning products “Superfloc” for new installations and
CHR “Central Heating Restorer” for retrofits)
Warning for all Systems
The boiler fittings can’t support any weight. Support all
of the plumbing system externally.
Do not apply torque to the boiler fittings. Hold the fitting
when installing, otherwise damage to the unit will occur.
The Trinity boiler employs a pneumatic
modulation system. This modulation system
increases or decreases the velocity of the
blower, to meet the demand for heating. The
gas valve senses this change in blower
pressure and introduces the required amount
of gas to ensure correct combustion.

Caution: This boiler is designed to operate in residential and commercial heating systems, and is
not intended for:
1. Outdoor installations, or unheated spaces, which can cause freezing.
2. Process heating of potable water, or any other fluids.
3. Un-pressurized, and gravity feed heating systems.
4. Heating systems with very low pressures or flow.
IF FOR ANY REASON THE
INPUT SCREW IS
ADJUSTED, A
“COMBUSTION ANALYZER”
MUST BE USED TO ENSURE
SAFE AND PROPER
OPERATION.
