Starting the
Gas Fired Boiler
STOP! Make sure you have read and
followed all previous safety information.
Check with local authorities where
approval for start-up is required. In
some localities, final inspection of
services may be required.
In general, ensure that the boiler area is
in conformance with established boiler
room requirements. Review national
and local codes.
Carry out the following procedure on the
initial start up of the boiler and on every
subsequent occasion when restarting the
boiler after a shut down.
1. Close the blow-down valves.
2. Close the water gauge drain valve.
3. Open main steam stop valve at the top
of the boiler.
4. Open the water feed valve on the boiler.
5. Open valves on makeup water line to
return if return system is used.
6. Place feedwater pump fused switch in
the "on" position.
NOTE
The pump will continue to operate until
the water reaches the correct level in the
boiler. This level is approximately the
center of the water gauge glass.
7. Activate the boiler power on switch,
located on the side of the panel box.
8. With the unit full of water the low water
safety relay(s) will be in a lock-out
mode. Press the low water safety relay
manual reset button located on the side
of the control panel box.
Gas Burner Set Up
1. Open the manual gas cocks on the pilot
and main lines of the gas head.
2. Switch on the main power to the burner.
The water level relay is equipped with a
manual reset. Depress the button on the
box.
3 The flame programmer is the
main control in the panel box. The
programmer in conjunction with a sensing
device, either a flame rod or a UV
scanner, "supervises" the ignition
sequence - proves the flame is
satisfactory, and finally"monitors" the
established flame. Should any fault occur,
either during the ignition sequence or
during normal running, the programmer
will immediately go to "lock-out" and the
burner will shut down.
NOTE
To reset the boiler burner after a “Lock
out” signal, push the reset button on the
control.
