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
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
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
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.
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
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
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
