IGNITION SYSTEM SAFETY SHUT-OFF DEVICE
After initial fill while the main burner is firing, shut off gas to the pilot and clock the time taken for the main
gas valve to shut down. If the safety control is functioning properly, power to the gas valve will be shut off
within 4 seconds of the pilot gas being shut off. If shut down takes longer, ignition control or gas valve may
be defective.

LOW WATER TEMPERATURE SYSTEMS
In applications where the heating system requires supply water temperatures below 110°F, a bypass line
must be installed upstream of the boiler pump so that outlet water can be re-circulated to raise the inlet
temp to a minimum of 110°F. Balancing valves, preferably globe valves are used to adjust flow. (See
Figure 5)
