BEFORE START-UP
Safe lighting and other performance criteria were
met with the gas manifold and control assembly pro-
vided on the boiler when the boiler underwent tests
specified in the latest edition of ANSI-Z21.13 Standard.
GENERAL
Before lighting up a new installation, water should
be flowing through the boiler. Regulator should be set
to minimum 12 PSI.
CAUTION:
Liquefied petroleum gas is heavier than air and
sinks to the ground. Exercise extreme care in lighting
boiler in confined areas.
FILLING SYSTEM - HEATING BOILERS
Fill system with water. Purge all air from the system
using purge valve sequence. After system is purged of
air, lower system pressure. Open valves for normal
system operation. Fill system through feed pressure.
Manually open air vent on the compression tank until
water appears, then close vent.

HEATING BOILERS
Fill through filler opening on the top on the
Air-X Tank to solution desired. Always maintain solu-
tion level in sight glass.
INITIAL START-UP - PUMP AND MOTOR
Many pumps are now direct-drive. They have no
coupler or bearing assembly. These pumps do not
require lubrication. Others require SAE-30 non-deter-
gent oil to lubricate both the motor and the bearing
assembly. Check pump motor for type before attempt-
ing to oil.
Clean dust and lint from pump and motor. Check
pump coupler and tighten if necessary.
Flush system before putting into operation to en-
sure that foreign material does not damage pump
seals.
CAUTION:
A. Pump must be off to check oil in bearing assembly.
B. Do not run pump without water in system.
