D.AFTER INSTALLATION:
1. Operate system through two complete cycles to check
for opening and closing in proper sequence, and prop-
er burner operation. DAMPER MUST BE IN OPEN
POSITION WHEN BOILER MAIN BURNERS ARE OPER-
ATING.
2. Perform installation checks as required by ANSI specifi-
cation Z21.66 or CSA B 149.1 latest edition for natural
gas and propane.
3. Replace the front cover of the boiler.
4. Check the troubleshooting section if problems arise
with the installation.
THERMOSTAT HEAT ANTICIPATOR ADJUSTMENTS
If the 24V room thermostat that controls the boiler has an adjust-
ment heat anticipator, it must be set to the AMP draw of the boil-
er. Connect the system to the thermostat and run the system.
Measure the current draw through the thermostat wires and set
anticipator accordingly. See "Appendix C."
OPERATING INSTRUCTIONS, BASIC
A. Before firing boiler, make these checks:
1. Relief valve is installed. Installation of the relief valve shall
be consistent with the ANSI/ASME Boiler Pressure Vessel
Code. Valve opening is NOT closed or reduced in size.
2. Draft hood is installed and vented to chimney.
3. All wiring is completed, following applicable wiring dia-
grams.
4. If a vent damper is added, damper is in full open posi-
tion. See instructions furnished with vent damper.
5. Using soap solution, check for gas leaks in all gas piping
from meter to boiler pilot and manifold. DO NOT use open
flame.
6. System is filled with water and vented.

FILLING AND VENTING WATER SYSTEMS

A. Fill the system with water. Vent or purge off air.
B. Fire the boiler as soon as possible (see following warning
and instructions) and bring water temperature to at least
82°C (180°F), while circulating water in the system.
C. Vent air and add water as needed to achieve operating pres-
sure on boiler gauge. Pressure must be between approxi-
mately 83 kPa (12 psi) (cold water) and 172 kPa (25 psi) (at
water temperature setting of high limit control), for boilers

equipped with 207 kPa (30 psi) relief valves. Boilers rated for
a higher pressure and equipped with a matching relief valve
may operate at a higher pressure, but no higher than 34 kPa
(5 psi) below the relief valve opening pressure.
D. Check for and repair any leaks before placing system in ser-
vice. Make sure that none of the automatic gas ignition sys-
tem components are exposed to water.
CLEANING AND FILLING A NEW STEAM BOILER
Before using steam boiler:
A. Check boiler to be certain it is ready for firing. DO NOT FIRE
into an empty boiler.
B. Be prepared to heat raw water to at least 82°C (180°F) as
soon as it is introduced into the boiler. This procedure will
remove dissolved, corrosive gases.
C. Provide drain line, with valve, from boiler. Use a bottom tap-
ping. Line and drain must be suitable for handling caustic
solution.
CLEAN STEAM BOILER SYSTEM
A. Fill the boiler to water line indicated on the boiler.
B. Follow start-up procedure for boiler and operate the boiler
with steam in the entire system for 2 or 3 days to bring oil
and dirt from the system to the boiler. While system is in
operation, maintain the proper water level in the boiler by
slowly adding water to the boiler.
C. Shut down burner, cool down boiler and drain system.
D. Procedure to dissolve oil and grease in boiler:
1. Fill boiler to proper water line.
2. Prepare a boil-out solution of sodium hydroxide
(caustic soda) and tri-sodium phosphate:
NOTE: Use CAUTION in handling chemicals. Caustic soda
is harmful to skin, eyes and clothing.
(a)Proportions: 1 kg of each chemical per 465 L
(1 lb/50 U.S. gallons) of system water.
(b)Stir chemicals into water until dissolved and pour into
the boiler through a top tapping. Replace plug.
3. Start the burner; boil the water for at least 5 hours; shut off
the burner.
E. With CAUTION, drain the boiler solution to a safe location.
DO NOT LEAVE SOLUTION SITTING IN SYSTEM OVER 2
HOURS.
F. Wash the water side of the boiler thoroughly using a high
pressure water stream. Fill and drain the boiler several times.
