clearance is acceptable between one pair of Cailber boilers. A 24 in (610
mm) clearance is acceptable between pairs of Caliber boilers. Refer to
Figure 2.
3. Ensure all labels on the boiler will be fully visible for maintenance and
inspection.
Install Boiler Trim
Each Caliber boiler is supplied with a safety relief valve sized in accordance with
ASME requirements. The safety relief valve is shipped loose and must be fi eld-
mounted into the water outlet manifold.
Adhere to the following installation requirements:
1. The safety relief valve must:
» Be connected to the coupling located in the top rear outlet
section of the boiler.
» Be installed in the vertical position.
» Be installed with a 4 inch (101.6 mm) nipple between the boiler
and the safety valve.
NOTE:  Safety relief valve size is determined by trim pressure and is supplied in the
trim kit along with appropriate bushing, inlet and outlet sizes.
The discharge of the safety relief valve is piped to the back of the boiler. The
installer must complete the piping to a safe location. The discharge pipe must:
» Not have a diameter less than the full area of the valve outlet.
» Be as short and straight as possible and so arranged as to avoid
undue stress on the valve.
» Be supported by means other than the safety valve itself.
» Be piped to avoid danger of scalding personnel.
NOTE:

Each boiler is shipped with a pressure-temperature gauge to be installed
in the outlet piping section of the boiler.
Install Water Piping
All water supplies contain some solids, dissolved gases or dissolved minerals.
These may promote corrosion, deposition and/or fouling of equipment. To
prevent these contaminants from impacting boiler performance, valve operation
and general pipe longevity, each location must be analyzed and treated
accordingly.
Adhere to the following for water piping installation:
1. Boiler has a maximum temperature diff erential across the heat exchanger
at high fi re, and has a minimum fl ow requirement. Use Table 2 to identify
!
WARNING
The discharge from the safety relief valve
must be arranged to ensure no danger
to personnel or equipment damage.
Provisions must be made to properly pipe
the safety relief discharge away from the
boiler to the point of discharge.
No shutoff of any kind shall be placed
between the safety relief valve and
the boiler, or in the discharge pipe
between the valve and the atmosphere.
Doing so may cause an explosion from
overpressure.
The hydronic system should never be
fl ushed while the boiler is attached to the
system since the debris could accumulate
in the boiler and block water from passing
through the heat exchanger.
Ensure all labels on the boiler are legible.
All connections and safety devices, both
mechanical and electrical, must be kept
clean, with ease of access for inspection,
use and maintenance.
Do not store or use gasoline or other
fl ammable vapors and liquids or corrosive
materials in the vicinity of this or any other
appliances.

CAUTION
Low fl ow conditions will cause excessive
cycling, damage and failure of equipment.
Circulating pump power supply must be
external to the boiler. The use of the SOLA
as a power supply is prohibited. The pump
contacts provided with the SOLA are for
controlling the pump only.
