Only qualified personnel should perform start up procedure.
1. Examine the electrical compartment for any loose or disconnected
component wiring. Check to make sure all of the control wiring has been
completed and been done correctly.
2. Remove the top cover of the unit by unscrewing the screws holding the lid in
place. Make sure all of the Ionic Beds are fastened securely to mounting pins.
Make sure gasket is in proper position then replace top cover.
3. Check and re-check incoming voltage source and control wiring for proper
connections and tightness of connections. Verify the wiring has been done in
accordance with local codes and the enclosed wiring diagram.
4. Turn on water and check for leaks.
5. Turn on gas supply and verify that all gas piping has been checked for leaks.
(Soapy water is not recommended for use inside the control cabinet.)
6. Make sure access doors and panels are secure.
7. Power up unit at breaker. Verify Steam Generation switch is in "ON" position
See Figure 22-1.
8. The unit will begin to fill. When the water level reaches
the low level control electrode the unit will perform its
precombustion checks.
9. After the precombustion checks are done, the unit will run at
100% for a period of 5 minutes.
10. During this 5 minute period, the burner must be adjusted for
proper operation. (100% Burner Output)
11. If the unit is not properly adjusted, the unit may not operate
properly.
12. A combustion analyzer capable of detecting the CO
2
level of the combustion
gasses will be required. Combustion checks will be done at the outlet of the
vent pipe of the GFH-150 or the 1/8" NPT plugs on the top of the collection
box of the GFH-300 or GFH-450. See Figure 22-3.
13. The target for the CO
2
level will be dependent on the
type of gas used. If Natural gas is being used, the
proper CO
2
level will be between 8.5 - 9.5%. For LP
operation, the CO
2
level will need to be adjusted
between 10 - 11%.
14. Turning the adjustment screw in the clockwise direction
will decrease the level of CO
2
, and turning the
adjustment screw counter-clockwise will increase the
CO
2
level.
15. After the unit has been properly adjusted, and the 5
minute warm-up period expires, the unit will go into
normal operation.
