CHAPTER 2: TECHNICAL FEATURES AND DIMENSIONS

2.1 Modulex EXT Technical Features

Compact, gas fired, Low NO

x

, condensing boiler.

Comprised of one sectional boiler body, suitable as a single boiler or in a cascaded group.

May be installed in either an inside or outside location.

Low internal water volume.

Fast response to load variations.

Flue exhaust outlet positionable on three sides.

Manifold delivery and return.

Made up of four or more heating elements (4 to 8), cast aluminum / silicon / magnesium.

Full range of modulation by variable speed blowers and premix burners.

Each heating element monitors its own water temperature, and will individually shutdown

if flow is interrupted, without affecting the other burner sections.

One gas supply line.

Individual modules capable of between 83 and 382.5 kBTU/hr.

These boilers are designed for use with category IV venting.
The boiler is supplied complete with all the safety and control devices in accordance with all

current regulations, and its technical and functional features comply with the regulations

prescribed by:

ANSI Z21.13 / CSA 4.9 - Gas-fired low pressure steam and hot water boilers.
