OPERATING INSTRUCTIONS

I. 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
180 degrees, while circulating water in the system.
C. Vent air and add water as needed to achieve operating
pressure on boiler gauge. Pressure must be between
approximately 12 psi (cold water) and 25 psi (at water tem-
perature setting of high limit control), for boilers equipped
with 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 5 psi below the relief
valve opening pressure.
D. Check for and repair any leaks before placing system in service.
Before firing boiler, make these checks:
1. System is full of water. Air is vented or purged.
2. Relief valve is installed in accordance with the ASME
Boiler Pressure Vessel Code, Section IV. Valve opening is
not closed or reduced in size.
3. Venting is installed according to instructions under "VENT
PIPING".
4. All wiring is completed, following applicable wiring dia-
grams.
5. Using soap solution, check for gas leaks in all gas piping
from meter to boiler pilot and manifold. DO NOT use open
flame.
II. INITIAL START
Safe lighting and other performance criteria were met when
testing various gas manifold and control assemblies used on
the Sentinel Series Boilers under the ANSI-Z21.13-1991
Standard.
INSTRUCTIONS
Follow the lighting instructions in this manual that apply to the
particular ignition system equipped on this boiler. (Also, see fig-
ures on page 2 for location of gas manifold, gas valve and control
assembly.) These instructions are also attached to the boiler.
1. Continuous Burning Pilot (24V).
FOR BOILERS EQUIPPED WITH HONEYWELL GAS
VALVE VR8200 or VR8300 (see figures 7 and 8).
SAFETY INFORMATION
FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING: If you do not follow these instructions exactly,
a fire or explosion may result causing property damage,
personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• DO NOT try to light any appliance.
• DO NOT touch any electric switch; DO NOT use any
phone in your building.
• Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire depart-
ment.
C. Use only your hand to push in or turn the gas control knob.
NEVER use tools. If the knob will not push in or turn by hand,
DON'T try to repair it, call a qualified service technician. Force
or attempted repair may result in a fire or explosion.
D. DO NOT use this appliance if any part has been under-
water. Immediately call a qualified service technician to
inspect the appliance and to replace any part of the control
system and any gas control which has been under-water.
Lighting Instructions
1. STOP! Read the safety information on this page.
2. Set the thermostat to lowest setting.
3. Turn off all electric power to the appliance.
4. Remove control access panel.
5. Push in gas control knob slightly and turn clockwise
to "OFF".
6. Wait five (5) minutes (longer for propane) to clear out any
gas, then smell for gas, including near the floor. If you
then smell gas, STOP! Follow "B" in the safety informa-
tion on this page. If you don't smell gas, go to next step.

7. Remove the pilot access panel located
below and behind the gas control unit.
8. Find pilot—follow metal tube from gas
control. The pilot is between two burner
tubes behind the burner access panel.
9. Turn knob on gas control counterclockwise
to "PILOT".
10. Push in red button all the way and hold in. Immediately
light the pilot with a match. Continue to hold the red but-
ton in for about one (1) minute after the pilot is lit.
