2A. System Start-up
1. Verify that the pump system is operating
properly:
a. Shut off the manual gas valve located
outside the boiler.
b. Raise the wall thermostat high enough to
call for heat.
c. The pump should come on immediately. If
it does not, test the electrical circuits.
2. Pilot and Main Burner Lighting:
a. The JVH boiler does not require manual
lighting. The pilot is controlled by the
automatic ignition system.
b. Different models of the JVi boiler utilize
various gas valves, (see Table 11).
Although the gas valves may have different
control knobs, they are all similar in
operation.
c. Understand and follow the operating
instructions, on page 14, that are applicable
to the type of ignition system installed on
the boiler.
3. The pilot and main burners will automatically
ignite when there is a call for heat.
