MODU-FIRE

Forced Draft Gas-Fired Boiler 2500-3000

1 INTRODUCTION

The

MODU-FIRE

Forced Draft

gas-fired boiler is a revolutionary advance. Harsco Industrial, Patterson-Kelley

now combines full-modulation burner control and forced draft advances with our time-tested modular hot water
boiler design. The result is a

full-modulation boiler utilizing reduced vent sizing for installation and cost

efficiencies. This boiler combines the best of our earlier designs with a new generation of burner, control and
operating technology. You will achieve high part-load efficiencies – but without the complexity you might expect
in this type of high performance boiler. It is high performance made simple and dependable for years of trouble-
free operation.

This manual covers installation and operation of the

MODU-FIRE

Forced Draft 2500 & 3000 MFD boiler.

The

model numbers may include a prefix to indicate special features or different options. While details may differ
slightly, basic operation is the same for all models. Boilers are built to operate with natural gas or propane. Check
the rating label for the correct gas type and flow rate.

The boiler is only a part of the complete heating system. This boiler may be fully operational and yet, because of
poor circulation, controls, or other operating characteristics, not deliver heat to the desired location. Additional
equipment such as temperature sensors, pumps, flow switches, balancing valves and check valves will be
required for satisfactory operation of any system. Harsco Industrial, Patterson-Kelley cannot be responsible for
the design or operation of such systems and a qualified engineer or contractor must be consulted.
