Caprice │ Installation and Operation Instructions - Installation Checklist C 85-3403210.0 INSTALLATION CHECKLISTStart-up1. Close automatic air vent and boiler drain cock.2. Boiler water pH range should be 7.0 - 8.5. If conditions are above 7, contact local water treatment company.3. Fill boiler with water until gauge reads 12-15 psi using auto fill device. Check for leaks.4. Open automatic air vent 1 turn.5. Bleed air from system. Starting at the lowest point in the building, open air vents one at a time and leave themopen until water comes out. Close all air vents, except the automatic air vent(s).6. Refill to correct pressure, 12-15 psi.Purging the System - Ensure all air is purged from the heating system as it can result inuneven heat distribution, water circulation problems, and shorten the life of the boiler.Antifreeze - If using antifreeze, use an inhibited propylene glycol specifically designedfor hydronic systems.Avoiding Corrosion - Two things that contribute to boiler corrosion are air in the system,and boiler water with pH levels outside the recommended range. Be sure to check the pHlevel of the water before filling the boiler and bleed the system of air before firing the burner.Pump Shaft Seals - Do not activate the burner until proper oil line connections have beenmade or failure of the pump shaft seal may occur.Check-out1.  Boiler heating system is filled with water and pressurized to 12-15 psi.2.  Bring the boiler up to temperature, once at temperature purge air from the boiler.3.  Purge air from the heating system piping.4.  Check that heating system piping and boiler are free from leaks.5.  Ensure Oil Supply tank is properly installed and vented as per applicable standards.6.  Oil line is secured to the burner in accordance with the burner manufacturers instructions.7.  Oil line is purged and free from leaks.8.  Do not start burner unless smoke hood, clean out door, HydroStat 3250, breeching, and burner door aresecured.9.  Burner has power and burner switch is turned on.10.  Verify sufficient combustion air is provided and applicable dampers are interlocked with burner.11.  Set burner flame by eye during initial start up. Make final adjustments with combustion test equipment.12.  Use the recommended air settings in Tables 2-1 to 2-4 as a starting point for the burner set-up.13.  Test HydroStat 3250 operation via the following methods: a) Adjust HI TEMP setting down until belowboiler water temperature, burner should go out, circulator should continue pumping; b) adjust HI TEMPsetting up until above boiler water temperature, burner should ignite.14.  Test field installed controls (i.e. external low water cut off or high limit) as per the control manufacturer’sinstructions included with the device. Burner should be operating when testing is conducted to verify thatthe burner changes state (on, off, on) when the controls are tested.15.  HydroStat 3250 settings are to the recommended settings defined in this manual.16.  Verify the boiler cycles with thermostat(s) demand (high temperature / low temperature).17.  Set thermostat to desired room temperature.18.  Allow boiler to complete at least one heating cycle to verify correct operation (minimum 15 minutes).19.  Review owner’s responsibilities (Section 1.0) and annual maintenance (Section 11.0) with owner.20.  Leave this manual with the owner and affix the instructions close to the boiler.
