Gas-Fired Boiler Introduction/Safety

1.0 INTRODUCTION
The P-K MODU-FIRE
®
Gas Fired Boiler is a revo-
lutionary advance; Patterson-Kelley now combines
full-modulation burner control with our time-tested
modular hot water boiler design. The result is
“modular full-modulation”- Modu-Fire! This new
hybrid boiler combines the best of our earlier de-
signs with a new generation of burner and control
technology. You will achieve even higher part-load
efficiencies – but without the complexity you might
expect in this type of high performance boiler. High
performance made simple and dependable for years
of trouble-free operation.
This manual covers installation of the P-K MODU-
FIRE
®
Boiler Series 1000, 1500, and 2000. The
model numbers may be followed by a prefix or suf-
fix letter in some cases 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 pro-
pane. Check the rating plate 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 oper-
ating 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 opera-
tion of any system. Patterson-Kelley cannot be re-
sponsible for the design or operation of such sys-
tems and a qualified engineer or contractor must be
consulted.
