III. 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 ANSI Z21.13.

1INSPECT INSTALLATION BEFORE STARTING.

2INITIAL START

a.FILL ENTIRE HEATING SYSTEM WITH WATER and vent air from system. Vent air from all heat distributing units and all high points in the piping of the system. When venting air from system keep ﬁll valve in open position to maintain water pressure. Make certain pressure reducing valve is installed between the ﬁll valve and the boiler. (See Figure 7)

Use the following procedure on a series loop system equipped with zone valves.

1. Close all but one zone valve.

c.Be sure that gas to pilot and main burners has been off for at least ﬁve minutes.

d.Open valve on main gas line at meter.

e.PURGE AIR FROM GAS PIPING. During the purge adequate ventilation must be provided and no smoking or open ﬂame permitted. (See Figure 10)

1.Open manual shutoff valve upstream of combination gas valve.

2.Loosen or remove inlet pressure tap plug in combination gas valve and when purging is complete, tighten or replace plug.

3.Check pipe and ﬁttings from meter to combination gas valve using soap solution or other approved methods.

f.TEST GAS PIPING — Test gas piping and connections between combination gas valve and manifold, manifold oriﬁces, and pilot piping for leaks after boiler is operating. Use soap solution or other approved method.

2.	Attach a hose to drain valve on purge ﬁtting and	g. Install enclosure cover and secure with #8 x ½” long
	extend hose to drain.	sheet metal screws.
3.	Open drain valve on purge ﬁtting.	3 OPERATING INSTRUCTIONS - See page 14.
4.	Close purge valve.	3 OPERATING INSTRUCTIONS - See page 14.
4.	Close purge valve.
5.	Open relief valve on boiler.
6.	Open ﬁll valve.
7.	When water discharges from relief valve, release
	the lever on top of the relief valve, allowing it to
	close.
8.	Allow water to run out of drain valve until zone
	has been purged of air and ﬁlled with water.
9.	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.
10.Close drain valve on purge ﬁtting.
11. 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 the set pressure of valve
	(normally 12 psi). Leave globe valve open.

12.Open purge valve.
