Burnham Indirect - Fired Water Heater AL SL Manual De Usuario

Do not apply heat directly to the cold-water inlet as it is made of plastic and will melt.

G. BOILER SUPPLY CONNECTIONS

WARNING: Boiler temperature must be controlled by the boiler high limit not to exceed 200°.

Failure to do so will create a hazardous installation and void the applicable limited warranties.

All water supply fittings on this heater are brass – do not over tighten or strip threads.

It is recommended to use a union as per Figures 1 and 2.

NOTE: Be sure to connect Boiler Supply Line (from the boiler) to the “HX in” fitting and Boiler

Return Line (to the boiler) to the “HX Out” fitting.

H. FILLING THE HEATER

Check that the temperature-and-pressure relief valve has been properly installed (mandatory

requirement).

Completely close the drain valve.

Open the highest hot water faucet to allow air to escape from piping.

Open the valve to the cold-water inlet and allow the heater and piping system to completely fill, as

indicated by a steady flow of water from the open faucet.
I. TPI THERMOSTAT INSTALLATION

Attaching TPI Thermostat to tank:

Place hole in back of TPI thermostat over immersion well. TPI thermostat should fit flush against the

tank without immersion well protruding beyond cover of TPI case. Use self-tapping screw provided

(Screw A) to attach TPI directly to the Alliance SL tank. (See TPI Diagram )

Inserting the Temperature Sensor:

Slide temperature sensor all the way into the immersion well – until it contacts the end.

(See TPI Diagram )

The sensor will measure temperature adequately by resting against the bottom of the immersion

well.

(Note: Sensor does NOT need to make intimate contact with entire well surface to work properly)

CAUTION: Sensor is soldered directly to TPI. DO NOT BEND SHARPLY OR OVERWORK.

J. TPI WIRING CONTROLS
NOTE: THE TPI CONTROL ELECTRONICS MUST BE POWERED WITH 4VAC.

Incoming 24VAC power must be connected to 24VAC connectors on the bottom right corner of TPI

Thermostat.

(See TPI Diagram 3)

The TPI 24VAC only requires 20mA, or about 0.5 Watts.

Connect control wiring to PUMP/TT normally open relay connections (rated for both 24V and 110V

wiring) on the bottom left corner of TPI control.

(See TPI Diagram 3)

TPI Wiring will vary depending on the type of boiler and valve controls in the system. Consult

attached Wiring Diagrams for appropriate wiring configuration for your system.

The Alliance SL water heater may operate as a separate heating zone using either the heating

system circulator and an appropriate zone valve, or a separate circulator dedicated for water heating.

(See Figure & ).

In both systems, the Alliance SL is controlled through the TPI thermostat on the heater.

(See Figures 1 & 2).

TPI thermostat calls for the heat when the temperature in the tank is below the set point (120°F) and

either activates a circulator or zone valve depending upon installation design.
