GALAXY INSTALLATION REQUIREMENTS The installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requirements, to the National Fuel Gas Code, ANSI Z223.1-latest edition. This installation must also conform to the additional requirements in this Slant/Fin instruction book. Installation and service to be performed by a qualified installer, service agency or the gas supplier. NATURAL GAS-FIRED BOILER LOCATION— Provide a level, solid foundation for the boiler.

All minimum clearances shown above must be met. This may result in increased values of some minimum clearances in order to maintain the minimum clearances of others. D.
PAGE 5
GALAXY BOILER ROOM AIR SUPPLY AND VENTILATION An ample supply of air is required to obtain combustion and ventilation. Room temperature over 100°F may cause nuisance tripping of the Blocked Vent Safety Switch. ALL AIR MUST COME FROM OUTSIDE, directly through wall openings to the boiler or through unsealed openings around windows, doors, etc. in the whole building. When buildings are insulated, caulked and weather-stripped, now or later on, direct opening to outside may be required and should be provided.

GALAXY VENT DAMPER INSTALLATION The vent damper referred to in the following instructions is the Slant/Fin Corporation vent damper. This device is design certified by A.G.A. for use ONLY on specific Slant/Fin Corp. gas boiler models. These boilers must also be equipped with a label which states that the boiler must be used with a Slant/Fin Corp. automatic vent damper device and indicates the proper vent damper model number. A. INSTALLATION INSTRUCTIONS BEFORE YOU START TO INSTALL 1.
PAGE 7
GALAXY WARNING—DANGER Once you have begun vent damper installation procedure, DO NOT restore electric power and gas supply until installation and inspection have been completed (in order to prevent the main burners from operating). DO NOT operate the boiler until the vent damper harness is plugged into vent damper operator. Failure to observe this warning may create a hazardous condition that could cause an explosion or carbon monoxide poisoning. B. 1.

GALAXY anticipator at the value measured. The set current should match power requirements by zone valves and relays. Add an additional 0.1 Amp to the measured currrent for vent damper. Refer to the manufacturer’s instruction of zone valve, vent damper and relays. Also, see instructions with the thermostat. ELECTRICAL WIRING DANGER: Before wiring, always turn off electric power supply, otherwise shock or death can result. 1. Power Supply A separately fused circuit is recommended. Use a standard 15 Amp.

GALAXY BOILERS EQUIPPED WITH HYDROSTAT CONTROL SETTING THE CONTROL NOTE: Settings can be checked using the TEST/SETTINGS Button. SETTING THE HIGH LIMIT The high limit is factory set at 190°F. To adjust, turn the HI TEMP Dial A until the desired setting is displayed. (Setting range: 100°-220°F) SETTING THE LOW LIMIT The low limit is designed to maintain temperature in boilers equipped with tankless coils used for domestic hot water. The low limit is factory set to OFF.

GALAXY 13 OPTIONAL FEATURES NOTE: The Program Mode – Pro – is accessed by turning the LO TEMP dial to a position just above OFF. THERMAL PRE-PURGE Thermal Pre-Purge is designed to maximize boiler efficiency. When activated, the control will supply latent heat that may remain in the boiler from a previous run cycle to the next heating zone that calls.

GALAXY OPTIONAL FEATURES Continued CIRCULATOR ACTIVATION OPTIONS When in the default mode, the HydroStat activates the circulator (C1/C2 contacts) on calls to T/TV. The control can be programmed to activate the circulator on calls to I1/I2 in place of, or in addition to, calls to T/TV. To change how the Circulator is activated 1. Turn the LO TEMP dial to access the Program Mode – indicated in the display as Pro 2. Turn the HI TEMP dial to select feature 4 3.

GALAXY 15 OPTIONAL FEATURES Continued RESTORE FACTORY DEFAULT SETTINGS To restore all features to the factory default settings (see following chart for default settings) 1. Turn the LO TEMP dial to access the Program Mode – indicated in the display as Pro 2. Turn the HI TEMP dial to select feature dEF 3. Push the Test/Settings Button to Y to reset all features to the default settings. 4.

GALAXY SYSTEM START-UP HOW THERMAL TARGETING WORKS At initial start up, with the Economy Feature active, the control establishes a 145°F target temperature. To test the high limit shut-off function, the Economy Dial must be turned to OFF. Once tested, restore the Economy setting. If the heating demand is high, the target will increase over time to satisfy the heat load. Thermal Targeting technology analyzes thermostat activity and continually evaluate how much heat the house requires.

GALAXY WATER PIPING A. Packaged water boilers are equipped with a water circulating pump, mounted to return the water into the boiler. For some installations, the pump should be on the supply main. See figure 10. B. For zoning and piping arrangement with indirect water heater, see figure 11 and 12. AIR CONTROL SYSTEM A. DIAPHRAGM-TYPE COMPRESSION TANKS are used to control system pressure in an AIR ELIMINATING SYSTEM: an automatic air vent is used to REMOVE air from the system water. See figure 8.

GALAXY 21 SAFETY INFORMATION FOR YOUR SAFETY READ BEFORE OPERATING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance is equipped with an ignition device which automatically lights the pilot. DO NOT try to light the pilot by hand. B. BEFORE OPERATING smell all around the appliance area for gas.

GALAXY b. Input for NATURAL GAS is approximately at rating when manifold pressure is 3-1/2" water column, but should be checked on the gas meter: Btuh Input = Btu/cu. ft. x cu. ft. metered in 3 minutes x 20 Example #1: For 1000 Btu/cu.ft. gas, this becomes: Btuh Input = cu. ft. metered in 3 minutes x 1000 Btu/cu.ft. x 20 Example #2: For 1050 Btu/cu.ft. gas, this becomes: Btuh Input = cu. ft. metered in 3 minutes x 1050 Btu/cu.ft. x 20 4.
PAGE 23
GALAXY 23 E. BOILER ROOM AIR SUPPLY: check air vents for continued POSITIVE supply of air as required. Air needs are greatest in cold weather. Air vents must be open and free of obstruction. F. WATER SYSTEM CHECK: 1. System to be full of water, and pressure to remain stable at correct setting on gauge. 2. Air control system: noise and air binding in radiation should not occur. 3. Water lines: slightest leaks should be corrected. 4. Low water cutoff, for operation (see instructions furnished with unit). 2.
PAGE 24
GALAXY BURNERS FAIL TO OPERATE CAUSE 1. Safety pilot out, or flame too low. 2. Gas supply valve shut off. 3. Electric switch open. 4. Blown or defective line fuse. 5. Operating or limit control contacts open or dirty. 6. Defective gas valve or pressure regulator; or plugged bleed line. 7. Defective low voltage transformer. 8. Obstruction at main burner orifice. 9. Break in wiring or loose contact at control terminals. 10. Improper wiring. 11. Improper controls. 12.

GALAXY PIPING A HEATING - COOLING SYSTEM TO A WATER BOILER AND CHILLER The chiller must be piped in parallel with the boiler. Figure below illustrates a method of piping a heating-cooling system to a water boiler and a chiller. Hand valves (shown) or automatic valves must be installed to prevent circulation of chilled water in the boiler or hot water in the chiller.
