Product Description

2.1

Product Applications

The boiler is designated for use as a hot water heating
boiler for space heating applications and to heat domes-
tic hot water by means of an indirect fired tank for single
and multi-family homes and small commercial heating
applications.

Please observe the technical data on the rating label
and technical information (

Chapter 3, page 7), to en-

sure proper application of this product.

2.2

Product Description

The G125 BE is a oil fired low temperature boiler with
boiler water temperature regulation.

The boiler consists of:

–

Optional Logamatic control

–

Boiler jacket

–

Boiler block with insulation

–

Burner

The optional Logamatic control manages most control
functions in a heating system.

As an alternative, a Aquasmart control can be used for
boiler control.

The boiler jacket serves to reduce energy loss and as a
noise reducing agent.

The boiler block transfers the heat generated by the
burner to the boiler water. The insulation reduces the
stand-by losses.
