After a few seconds, the display should flash “H”, indicating that the boiler has been driven to high fire. Allow the boiler to operate for approximately 5 minutes before taking combustion readings. Note: after 15 minutes, the boiler is automatically released from high fire hold. Be sure to restore high fire hold if additional time is needed to obtain high fire combustion readings. 7. Perform a combustion test. Boilers equipped with a concentric vent system have a flue gas sample tap located in the boiler vent collar (under the screw cap). 8. While the burner is at high fire adjust the throttle as needed to obtain the CO2 (or O2) settings shown in the Table 23: • To reduce the CO2 (increase the O2) turn the throttle clockwise • To increase the CO2 (reduce the O2) turn the throttle counter-clockwise Make adjustments in increments of 1/8 to 1/4 turn and allow the boiler at least a minute to respond to each adjustment before making another. In general, the CO level will be at its lowest somewhere in the CO2 range shown in this table.

Verify that the gas inlet pressure is between the upper and lower limits shown in Table 24 with all gas appliances (including the converted boiler) both on and off: 10. A label sheet is provided with the boiler for conversions from natural to LP gas. Once conversion is completed, apply labels as follows: • Apply the “Rating Plate Label” adjacent to the rating plate. • Apply the “Gas Valve Label” to a conspicuous area on the gas valve. WaRning The pressure regulator has been factory set using precision instruments and must never be adjusted in the field. The gas valve outlet pressure is the same for both natural gas and propane. Make sure that all adjustments are made with the throttle, not the pressure regulator. attempting to adjust the pressure regulator will result in damage to the gas valve and may cause property damage, personal injury or loss of life. 0 WaRning The throttle adjustments shown in Table 22 are approximate. The final throttle setting must be found using a combustion analyzer. Leaving the boiler in operation with a CO level in excess of the value shown in Table 2 could result in injury or death from carbon monoxide poisoning. nOTiCE if the throttle is very far out of adjustment on the “rich” (counter-clockwise) side, the boiler burner may be running at 0% Excess Air or even with air deficiency. at 0% Excess air the CO2 readings will be either 11.9% CO2 for natural gas or 1 .8% CO2 for LP gas (O2 will be 0%) and CO level will be extremely high (well over 1000 PPM). If the burner operates with air deficiency, the following phenomena may be observed: % CO2 will actually drop (% O2 will increase) as the throttle is turned counterclockwise % CO2 will actually increase (% O2 will drop) as the throttle is turned clockwise If the boiler appears to operate with air deficiency, turn the throttle clockwise to increase the amount of Excess air to the burner. as the throttle is turned clockwise, the CO2 level will rise, eventually peaking @ 11.8% or 1 .8%, depending of the type of gas being used, before falling (conversely, O2 level will drop to 0% before rising). after this happens, continue turning the throttle clockwise, until CO2 level drops (or O2 level increases) to the values shown in Table 20 or Table 2 .

Fill in the date of the conversion and the name and address of the company making the conversion with a permanent marker. 11. Refer to Section XI “System Start-up” of this manual and perform any checks not already completed. 1 Xii. Operation I. Factory Preset Boiler Operating Parameters (See Table 25 for Parameter Descriptions) A. The Alpine (ALP) boiler uses a microprocessor based Honeywell control, known as a “MCBA”, to manage all boiler functions including flame supervision and modulation. Two set point or “target” boiler supply temperatures are stored in the MCBA’s memory; one for space heating and one for domestic water production. If an outdoor temperature sensor is connected to the boiler, the space heating supply set point will automatically adjust downwards as the outdoor temperature increases. For more information on this feature see the discussion on boiler water reset below. The MCBA modulates the boiler input by varying the fan speed. As the fan speed increases, so does the amount of gas drawn into the blower. As a result, a fairly constant air-fuel ratio is maintained across all inputs. The MCBA determines the input needed by looking at both current and recent differences between the supply temperature and the set point temperature. As the supp...
