WARNING
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.
equipment.
2. Install the water safety valve into the opening on the boiler, piping the
outlet of the valve to a safe blow-off point.
NOTE:

Unless otherwise specifi ed, the safety valve supplied with the boiler
is pre-set. This valve is provided as a safety device for the boiler and should
not be used as the sole protection for other equipment.
3. Install the water temperature / pressure gauge assembly.
4. The drain valve is connected to the lowest opening at the bottom rear of
the boiler. Pipe from the outlet of the valve to a safe drain point. Provision
should be made to allow easy access to the drain valve.
Electrical Installation
Adhere to the following for electrical installation:
1. Connect wiring as shown in wiring diagram which is furnished inside the
electrical control panel. Be sure to install a fused switch for the contactors
and a separate fused switch for the circulating pump(s).
2. A correctly sized fused disconnect should be fi tted as close to the boiler as
possible and connections made to the boiler panel in compliance with NEC
(National Electrical Code) and local codes.
3. Typical 120VAC controls allow for a +10% and a -15% voltage fl uctuation.

Motors
1. Motors are designed to operate within the following limits at the motor
terminals:

AC power supplied is /- 10 % of the motor rated voltage with the
rated frequency applied. OR

AC power supplied is /- 5% of the rated frequency and with the
rated voltage OR

A combined variation in voltage and frequency of +/- 10% (sum of
absolute values) of rated values provided the frequency variation does not
/-5% of rated frequency.
2. For 3 phase motors, the line to line full load voltage must be balanced
within 1% of the rated motor voltage. If the motor is rated 208-230V, the
voltage deviations must be calculated from 230V. Operation outside of
the above limits will degrade motor performance. 575V rated motors
cannot be operated at voltages above 600V. Depending on the motor
manufacturer, a 208V rated motor may not be able to run below the design
voltage.
