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.
