V. Condensate Disposal A. Condensate Trap and Drain Line. 1. All condensate, which forms in the boiler or vent system, collects in the sump under heat exchanger and leaves the boiler through factory installed condensate trap. 2. The trap allows condensate to drain from sump while retaining flue gases in the boiler. The trap has factory installed overflow switch, which shuts down the boiler in the event the drain line becomes obstructed, preventing proper condensate removal.
Figure 29: Condensate Trap and Drain Line
VI. Water Piping and Trim WARNING Failure to properly pipe boiler may result in improper operation and damage to boiler or structure. Install boiler so that the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during appliance operation and service (circulator replacement, etc.). NOTICE Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and can lead to boiler failure.

Install close nipple into tee branch, then, screw the assembly into boiler left side front ¾” tapping making sure tee run outlets are in vertical plane and parallel to boiler side. c. Mount ¾” MPT x ¾” FPT Pressure Relief Valve into the tee top outlet. d. Install Drain Valve into the tee bottom outlet. 2. ALP399 Boiler Model a.
B. Piping System To Be Employed. NOTICE Alpine (ALP) boilers are designed to operate in a closed loop pressurized system. Minimum pressure in the boiler must be 12 PSI. Proper operation of the Alpine (ALP) boiler requires that the water flow through the boiler remain within the limits shown in Table 11, any time the boiler is firing. Failure to maintain the flow through boiler within specified limits could result in erratic operation or premature boiler failure. 1.
a. The flow rate through the isolated near-boiler loop is maintained by factory recommended and installer supplied boiler circulator. b. The flow rate through the isolated near-boiler loop is completely independent of the flow rate through the heating system loop(s). c. The flow rate through the heating system loop(s) is controlled by installer sized/provided system loop circulator(s). d.

Figure 38: Wiring for MCBA Modulating Boiler Control Time Delay Relay Box 5. If the boiler installation site may be subject to low supply voltage conditions or “brownouts”, that would affect MCBA Modulating Boiler Control operation, a separate optional Time Delay Relay Box (P/N 101693-01) installation is strongly recommended. See Figure 38 “Wiring for MCBA Modulating Boiler Control Time Delay Relay Box” and follow the following installation steps: a. Turn off power to boiler. b.
IX. Boiler Stacking For installations with unusually high space heating and/or domestic hot water heating loads, where employing two (2) Alpine (ALP) boilers will offer the benefits of greater operational efficiency, floor space savings and boiler redundancy, the Alpine (ALP) boilers may be installed stacked one on the top of the other. Refer to Table 18 “Alpine (ALP) Boiler Model Stacking Combinations” for details.
vertical (roof) vent terminals, if level with each other, are spaced no closer then 12 inches horizontally. If vertical vent terminals cannot end in one plane, they must be spaced no closer then three (3) feet horizontally. Follow instructions in Section IV “Venting” of the manual for specifics of individual boiler vent termination. Follow instructions in Section V for each individual boiler flue gas condensate line construction and condensate disposal.
X. Modular Installation A. General Guidelines 1. Read and follow all venting, combustion air, water piping, gas piping and electrical instructions contained in the Installation, Operating and Service Instructions unless otherwise instructed in this section. 1. Each individual module (boiler) must have own combustion air intake pipe and combustion air intake terminal. Refer to Section IV “Venting” of these Instructions for individual module (boiler) combustion air intake guidelines and options. 2.

If vertical vent terminals cannot end in one plane, they must be spaced no closer than three (3) feet horizontally. D. Modular Boiler Gas Piping 1. Individual module (boiler) gas pipe sizing specific details 6. Chimney chase concentric venting is permitted for modules, when stackable, providing concentric vertical (roof) vent terminals, if level with each other, are spaced no closer then 12 inches horizontally.
Figure 42: Modular Boiler Water Piping w/Domestic Hot Water Heater Installing a low water cutoff in the system piping of modular boilers is strongly recommended and may be required by Local Codes.
Figure 43: Modular Boiler Water Piping w/Domestic Hot Water Heater (Continued)
The Tekmar 265 Control (or equal) can control either 3 modulating boilers or 2 modulating boilers and an Indirect Water Heater. When a call for heat is received by the Tekmar 265 Control, the control will fire either one or more boilers in either parallel or sequential firing mode to establish a required reset water temperature in the system supply main based on outdoor temperature.
The Tekmar 264 Control (or equal) can control up to four (4) boilers and an Indirect Water Heater by utilizing stage firing. When a call for heat is received by the Tekmar 264 Control, the control will fire either one or more boilers in sequential firing mode to establish a required reset water temperature in the system supply main based on outdoor temperature.
XI. System Start-up A. Verify that the venting, water piping, gas piping and NOTICE electrical system are installed properly. Refer to installation instructions contained in this manual. If it is required to perform a long term pressure test of the hydronic system, the boiler should first be isolated to avoid a pressure loss due to the escape of air trapped in the boiler. To perform a long term pressure test including the boiler, ALL trapped air must first be removed from the boiler.
Alpine™ Series Lighting and Operating Instructions Figure 46: Lighting Instructions 67
Figure 47: Burner Flame H. Purge Air From Gas Train K. Perform Combustion Test Upon initial start-up, the gas train will be filled with air. Even if the gas line has been completely purged of air, it may take several tries for ignition before a flame is established. If more than 5 tries for ignition are needed, it will be necessary to press the reset button to restart the boiler.
N. Adjust Supply Water Temperature As shipped, the heating and indirect water heater set point supply temperatures are both set to 180°F. If necessary, adjust these to the appropriate settings for the type of system to which this boiler is connected. See Section XII “Operation” of this manual for information on how to do this. O. Adjust Thermostats Adjust the heating and indirect water heater thermostats to their final set points. P.
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.
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 23 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.
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.
Table 25: Parameter Descriptions Access Parameter Code No.
Figure 50: Basic Menu Tree
D. Two basic types of errors codes are shown on the display: 1. Soft Lockout Codes – When a soft lockout occurs, the boiler will shut down and the display will alternate between the number “9” and the letter “b” followed by a two digit service code. A list of these codes, and their meanings, is shown in Table 29 in Section XIV Troubleshooting. The boiler will automatically restart once the condition that caused the lockout is corrected. 2.
Additionally, either the keypad or the personal computer can be used to obtain information about the boiler current status and operating history. A.

XIII. Service and Maintenance DANGER This boiler uses flammable gas, high voltage electricity, moving parts, and very hot water under high pressure. Assure that all gas and electric power supplies are off and that the water temperature is cool before attempting any disassembly or service. Do not attempt any service work if gas is present in the air in the vicinity of the boiler. Never modify, remove or tamper with any control device.
3. Inspect the wiring to verify the conductors are in good condition and attached securely. 10. Reinstall the burner, burner hood and fan/gas valve assembly. 11. Reconnect any wiring which has been disconnected. CAUTION Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. 4. Remove the ignition electrode and inspect it for oxides. Clean the oxides from the electrode with steel wool.
b. Equivalent system freeze protection products may be used in lieu of product referenced above. In general, freeze protection for new or existing systems must use specially formulated glycol, which contains inhibitors, preventing the glycol from attacking the metallic system components. Insure that system fluid contains proper glycol concentration and inhibitor level. The system should be tested at least once a year and as recommended by the manufacturer of the glycol solution.
