CS300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS
BOILER OPERATION
WARNING: Before proceeding read and fully
understand the instructions contained in this
manual. Do not attempt to operate this boiler if
it has not been installed in accordance with the
guidelines set forth in this manual. Failure to
comply with this warning can result in extensive
property damage, severe personal injury or
death!
Steam Boilers
Fill the boiler with water to a level 1" below the normal
water level line of 33 1/4". Clean the newly installed
sections as outlined below:
CAUTION: Do NOT use any petroleum based
cleaners to clean the boiler or the hydronic seals will
be damaged!
1. Pipe the skimmer tapping on the front of one of the
end sections to a floor drain using 1 1/2" pipe.
2. Adjust the boiler water level until water begins to
flow out of the skim piping at a slow rate.
3. Fire the boiler and maintain a water temperature of
180°F to 200°F. It may be necessary to cycle the boiler.
4. Adjust the water feed to prevent the build up of
pressure within the boiler. Continue the skimming process
until the discharge runs clear.
5. Shut the boiler off and allow the boiler to cool to
100°F. Remove the skim piping and plug the tapping.
Open the blowdown valve and flush the boiler until the
discharge runs clear.
6. Close the blowdown valve and fill the boiler with
water to a level 1" below the normal water level line.
7. Check the traps and vents for proper operation.
LIGHTING INSTRUCTIONS
A. If this appliance is equipped with a continuous pilot
it must be lit by hand. Follow the lighting instructions
exactly when lighting the pilot. If this appliance is
equipped with an intermittent pilot, the ignition control
will automatically light the pilot. Follow the operating
instructions and do not try to light the pilot or burner
by hand.
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.
C. 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.
CAUTION: To prevent being burned, stand clear of
the boiler during ignition and don't touch any hot
metal parts.
Continuous Pilot Systems
1. STOP! Read the safety information above. If, at any
time, the boiler will not operate properly, follow the
instructions "TO TURN OFF GAS TO BOILER" and call
your service technician or gas supplier.
2. Set the operating control to off or its lowest setting.
3. Turn off all electric power to the boiler.
4. Close the manual main and pilot gas shut-off valves.
5. Wait five (5) minutes** to clear out any gas. Then
smell for gas, including near the floor. If you smell gas,
STOP! Follow "B" in the safety information above (to the
left) on the label. If you don't smell gas, go to the next
step.
6. Remove the front grill(s).
7. Connect a manometer having a minimum capacity
of 20" WC to the outlet pressure port of the gas valve.
Make sure that the gas supply piping has been purged
of air and that all gas joints up to the manifold have been
thoroughly checked for leaks.
8. Locate the pilot(s).
9. Open the petcock pilot valve.
10. Push and hold down the red button on the pilotstat.
Light the pilot with a match and wait approximately one
(1) minute before releasing the button. The button should
pop back and the pilot(s) remain lit. For two pilot systems
repeat this procedure for the other pilot. If a pilot will not
stay lit after several tries, adjust pilot reg to higher
pressure. Turn reg clockwise to increase and
countercloskwise to decrease pressure. If pilot still fails
to light, close the manual pilot valve and call your service
technician or gas supplier.
11. With the pilot(s) lit, turn on all electric power to the
appliance.
12. Open the manual main gas shut-off valve.
13. Set the operating control so there's a call for heat.
