A. Electrical Service Field Wiring

120 volt power supply field wiring connects to limit control.

Provide appropriate overcurrent protection and service

disconnect switch�

B. Thermostat Installation

Thermostat should be installed on inside wall about

four feet above the floor.

NEVER install thermostat on outside wall�

Do not install thermostat where it will be affected by:

• Drafts

• Hot or cold pipes

• Sun light

•

Lighting fixtures

• Television sets

• Fireplace or chimney

Check thermostat operation by raising and lowering

thermostat as required to start and stop burner�

Instructions for final adjustment of thermostat

are packaged with thermostat ( adjusting heating

anticipator, calibration, ect�)�

C. Hydrostat 3250 Hi-Limit/LWCO Control

See Figure #19

Combined High Limit, Low Limit and Low Water Cutoff.

• Well mounted to front of boiler�
• Temperature probe installed in well is attached to

4-pin plug inside limit control box�

• If connecting boiler to indirect water heating system

change zone switch from Z to I on Hydrostat

controller�

• Adjust High Limit and Low Limit dials to desired

temperatures�

•

See control manufacturer specific instructions for

details on operation and settings�

• See Figures #20 and #21 for wiring connections�

Electrically bond boiler to ground in accordance with

requirements of authority having jurisdiction� Refer to:

USA-

National Electrical Code, ANSI/NFPA 70.

12.2 Sequence Of Operations

On call for heat, thermostat will actuate, completing

circuit to limit� In turn, circulator and ignition systems are

activated and ignition will begin�
In event boiler water temperature exceeds high limit

setting on boiler mounted limit, power will be interrupted

between limit and ignition system. Power will remain off

until boiler water temperature drops below high limit

setting� Circulator will continue to operate under this

condition until thermostat is satisfied.

WARNING

Electrical shock hazard� Turn OFF electrical power supply

at service panel before making electrical connections�

Failure to do so could result in death or serious injury�

12.1

Electrical wiring shall conform to requirements

of authority having jurisdiction or in absence of such

requirements ANSI/NFPA No. 70 National Electrical
