Installation, Operation and Maintenance Manual
_____________________________________________________________________________
3
Refer to National and all applicable Local Codes for specific installation requirements.
NOTE:
Reference heating element clearance requirements for particular boiler to allow for removal of
elements. Standard minimum suggested clearance is 21 inches.
1.
The boiler should be mounted on a solid level foundation.
2.
All piping should be installed by a licensed plumber.
3.
When any type water feed other than a pump feed is used, the existing water supply pressure must be 10 PSIG greater
than boiler operating pressure to assure water supply maintains proper water level in boiler. Lack of water can result in
improper boiler operation. Keep feed water valves open at all times during normal operation.
4.
Connect steam line with customer supplied outlet valve to boiler steam outlet.
5.
During normal operation, keep drain valve closed.
6.
If pump and boiler are plumbed within 30 ft (pipe length), a minimum of two check valves are required on boiler
to avoid damage to pump.
NOTE: THE SAFETY VALVE SHALL NOT BE PLUMBED WITH A DRAIN LINE SIZED LESS THAN
THE OUTLET SIZE OF THE SAFETY VALVE.
Ground boiler according to National Electric Code requirements to avoid shock.
Use proper sized wire. Power wiring to boiler should be in accordance with Local and N.E.C. requirements following
wiring diagram supplied. Wire size specified adjacent to field wiring terminal block(s).
Use 90˚ C copper wire only.
Purchaser should use a disconnect switch employing circuit breakers or fuses between the main power source and the boiler.
Boilers are susceptible to lightning damage because of plumbing water lines.
Industrial type lightning/surge protectors should be installed according to the manufacturer's
recommendation at your service entrance. Consult your contractor or electrical dealer.
1.
The unit is pre-wired and tested. Connect control circuit voltage at the control circuit terminal block.
2.
With the main power off, make sure that all wiring terminations are tight to avoid arcing, carbonizing and/or overheating of
contacts.
Substitution of components or modification of wiring systems voids the
warranty and may lead to dangerous operating conditions.
3.
Instructions for water feed control system (i.e. motor and pump or solenoid feed).
a.
Check the voltage of the motor or solenoid before making electrical connection.
b.
The water feed circuit should be wired to the junction box provided
.
c.
Motors rated greater than 1/3HP or are not 120VAC single phase require the use of suitable motor starter.
d.
Amperage/Wire Size – For correct sizing refer to the label on the boiler located next to the field wiring terminals.
This label states the wire size (AWG or MCM), minimum temperature rating (90˚C) and conductor material (copper only).
Deviation from this information may result in improper or unsafe boiler operation.
