SECTION II - OPERATING INSTRUCTIONS

Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the boiler when the boiler underwent tests specified in American National Standard for Gas-Fired Low-Pressure Steam and Hot Water Boilers, ANSI Z21.13b-1994.

1. MAIN BURNER CHECK - Check main burners to see that they were not dislodged during shipment. Rear of burners should be in the slots in the rear of burner tray and the front of the burners should be seated completely on the orifices.

2. INITIAL START -

A. FILL ENTIRE HEATING SYSTEM WITH WATER and vent air from system. Use the following procedure on a Series Loop System equipped with zone valves. (See Figure 3).

1.Close isolation valve in boiler supply piping.

2.Isolate all circuits by closing zone valves or balancing valves.

3.Attach a hose to bib cock located just below isolation valve in boiler supply piping. (Note - Terminate hose in five gallon bucket at a suitable floor drain or outdoor area).

4.Starting with one circuit, open zone valve.

5.Open bib cock.

6.Open fill valve (Make-up water line should be located directly above isolation valve in boiler supply piping).

7.Allow water to overflow from bucket until discharge from hose is bubble free for 30 seconds.

8.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.

9.Close bib cock, continue filling the system until the pressure gauge reads 12 psi. Close fill valve. (Note - If make-up water line is equipped with pressure reducing valve, system will automatically fill to 12 psi. Leave globe valve open).

10.Open isolation valve in boiler supply piping.

11.Remove hose from bib cock.

B.Turn ROOM THERMOSTAT to lowest setting.

C.Be sure that gas to pilot and main burners has been off for at least five minutes and vent damper (if used) has been in the open position.

D.Turn "OFF" the electric switch serving boiler.

E.Open valve on main gas line at meter.

F.PURGE AIR FROM GAS PIPING. This procedure will vary with equipment furnished but in all cases adequate ventilation must be provided and no smoking or open flame permitted. To determine which of the procedures outlined in succeeding paragraphs is applicable, match suffix of boiler model found on Rating Plate with paragraph heading:

1.Standing Pilot Models (Suffix V):

a.Keep electric switch "OFF".

b.Open Manual Shut-off Valve upstream of Combination Gas Valve.

c.Disconnect Pilot Tubing at gas valve (Purge must not be into combustion chamber).

d.Turn Main Gas Knob on Combination Gas Valve to

Intermittent Ignition (HSP)

"Pilot" Position. Depress and hold in this position until purging is complete. Turn Main Gas Knob to "off" position.

e. Reconnect pilot tubing and check pipe and fittings from meter to combination Gas Valve for leaks using soap solution or other approved method.

2.Intermittent Ignition Models (Suffix S):

a.Turn "ON" electric switch serving boiler.

b.Open Manual Shut-off Valve upstream of Combination Gas Valve.
