Figure 17: Operating Instructions

Adjust gas valve pressure regulator as necessary (turn adjustment screw counterclockwise to decrease manifold pressure, or clockwise to increase manifold pressure). If pressure can not be attained, check gas valve inlet pressure. If less than minimum gas supply pressure listed on rating label, contact gas supplier for assistance.

3.Recheck Main Burner Flame

4.Adjust thermostat to normal setting.

P.COMBUSTION CHAMBER BURN-OFF

1.The mineral wool combustion chamber panels contain a cornstarch based binder that must be burned out at installation to prevent odors during

subsequent boiler operation.

2.Ventilate the boiler room, set the high limit to its maximum setting, set the thermostat to call for heat. Allow the boiler to fire for at least an hour or until the odor from the cornstarch has dissipated.

3.Return the high limit and thermostat to their desired settings.

Q.Review User's Information Manual and system operation with owner or operator.

R.Post instructions near boiler for reference by owner and service personnel. Maintain instructions in legible condition.
