completely read, understand and follow all 
instructions in this manual before attempting 
start-up.
WARNING - BEFORE INSTALLATION OF THE BOILER 
IS CONSIDERED COMPLETE THE OPERATION 
OF THE BOILER CONTROLS SHOULD ALL BE 
CHECKED, PARTICULARLY THE LOW WATER CUT-
OFF AND THE HIGH LIMIT CONTROLS.
6.1    FILL ENTIRE HEATING SYSTEM WITH WATER 
and vent air from system.  Use the following 
procedure on a system equipped with zone valves.
1)   Close all but one zone valve.
2)   Open drain valves on boilers.
3)   Open fill valve.
4)   Close purge valve.
5)   Open relief valves on boilers.
6)   Allow water to run out of drain valve until zone 
has been purged of air and filled with water.
7)   Open zone valve to the second zone to be purged, 
then close the first.  Repeat this step until all zones 
have been purged but always have one zone open.  
At completion open all zone valves.
8)   Close drain valve.
9)   When water discharges from relief valves, release 
the lever on the top of the relief valves, allowing 
them to close.
10)   Continue filling the system until the pressure gauge  
   reads 12 psi.  Close fill valve.
11)   Open purge valve.
12)   Start system circulator.
The maximum operating pressure of this boiler is 
50 psig.  Never exceed this pressure.  Do not plug 
or modify pressure relief valve.
6.2    TEST GAS PIPING.  Test main and pilot gas piping 
at boiler for leaks at all piping connections and valves.  
Refer to 4.5.6.
6.3    PURGE GAS PIPING OF AIR
1)   Disconnect electric service to boiler.
2)   Turn control knob on all modules' combination gas 
valves to off position.
3)   Open valve on main gas line at meter.
4)   Starting with Module #1 disconnect pilot tubing 
from outlet side of combination gas valve.  Depress 
Control Knob slightly and turn to "Pilot" position.  
Depress Knob fully and hold until gas issues from 
disconnected fitting.  Release Knob and reconnect 
pilot tubing.  Turn control knob to off.
5)   Repeat (4) for each module in sequence.
6.4    Make sure that pilot tubing has been reconnected.  
Wait five minutes then proceed "To Light" in 
accordance with boiler operating instructions 
attached to the boiler jacket.  On boilers equipped 
with standing pilots, light the pilot of each boiler in 
sequence.
6.5    CHECK GAS INPUT rate to each boiler separately.  
Input rate must not exceed that shown on Rating Plate.  
For propane gas adjust regulator for a burner manifold 
pressure of eleven (11.0) inches water column.
 
  For natural gas, check input rate shown on boiler 
rating plate as follows:
1)   Consult local gas company for heating value of gas 
(BTU/Cu. Ft.).
2)   Set limit and operating control high enough so 
boiler will not shut off while checking input rate.
3)   All other gas burning appliances served by meter 
should be turned off temporarily while checking 
input rate.
4)   Check manifold pressure at 1/8" tapping on burner 
manifold.  Pressure should be approximately 
3½" water column for natural gas.  Adjustment 
of gas pressure can be made by turning regulator 
Service on this boiler should be undertaken only by trained and skilled personnel from a qualified service 
agency.  Inspections should be performed at intervals specified in this manual.  Maintain manual in a 
legible condition.
Keep boiler area clear and free of combustible materials, gasoline and other flammable vapors and liquids.
Do not place any obstructions in boiler room that will hinder flow of combustion and ventilation air.
The service instructions contained in this manual are in addition to the instructions provided by the 
manufacturer of the boiler components.  follow component manufacturer’s instructions.  component 
manufacturer’s instructions were provided with the boiler.  contact component manufacturer for replacement 
if instructions are missing.  Do not install, start up, operate, maintain or service this boiler without reading 
and understanding all of the component instructions.  Do not allow the boiler to operate with altered, 
disconnected or jumpered components.  Only use rePLAcEMENT cOMPONENTs IDENTIcAL TO ThOsE
