During Boiler Operation; Boiler Water; Freeze Protection Fluids - Baxi Luna HT 1.450 Notice D'installation Et D'entretien

BEFORE INSTALLING AND WHEN SERVICING BOILER
• To avoid electric shock, disconnect electrical supply before performing maintenance.
• To avoid severe burns, allow boiler to cool before performing maintenance.

DURING BOILER OPERATION

• Do not block flow of combustion or ventilation air to boiler.
• Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrical supply to circulator.
Instead, shut off the gas supply at a location external to the appliance
• Do not use this boiler if any part has been under water. Immediately call a qualified service technician to inspect
the boiler and to replace any part of the control system and any gas control that has been under water.

BOILER WATER

• If you have an old system with cast iron radiators, thoroughly flush the system (without boiler connected) to remove
sediment. The high-efficiency heat exchanger can be damaged by build-up or corrosion due to sediment.
• Do not use petroleum-based cleaning or sealing compounds in boiler system. Gaskets and seals in the system
may be damaged. This can result in substantial property damage.
• Do not use "homemade cures" or "boiler patent medicines." Substantial property damage, damage to boiler, and/
or serious personal injury may result.
• Continual fresh make-up water will reduce boiler life. Mineral build up in heat exchanger reduces heat transfer,
overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by make-up water
can cause internal corrosion in system components. Leaks in boiler or piping must be repaired at once to prevent
make-up water.
• We reccomend the use of water treatment additives to prolong the life of the boiler and prevent against corrosion
and contaminant build ups in the heating system.

FREEZE PROTECTION FLUIDS

CAUTION
• Never use automotive or standard glycol antifreeze, even ethylene glycol made for hydronic systems. Use only
inhibited propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is
toxic and can attack gaskets and seals used in hydronic systems. Ensure that the glycol used never exceeds
35% of the systems volume as this may damage the systems components.
• Consider piping and installation when determining boiler location. Any claims for damage or shortage in
shipment must be filed immediately against the transportation company by the consignee.
HEATING APPLIANCE REMOVAL FROM A COMMON VENT SYSTEM
At the time of removal of an existing heating appliance, the following steps shall be followed with each appliance remai-
ning connected to the common vent system placed in operation, while the other appliances remaining connected to the
common vent system are not in operation.
1. Seal any unused openings in the common vent system.
2. Visually inspect the venting system for proper size and horizontal pitch to determine if there is blockage, leakage,
corrosion or other deficiencies that could cause an unsafe condition.
3. If practical, close all building doors, windows and all doors between the space in which the appliance remains con-
nected to the common vent system and other spaces in the building. Turn on clothes dryers and any appliances not
connected to the common vent system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, at
maximum speed. Do not operate a summer exhaust fan. Close all fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust the thermostat so the
appliance will operate continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or
candle.
6. After it has been determined that each appliance remaining connected to common venting system properly vents
when tested as outlined, return doors, windows, exhaust fans, fireplace dampers and any other gas burning appliance
to their previous condition of use.
7. Any improper operation of the common vent system should be corrected so the installation conforms to the National
Fuel Gas Code, ANSI Z223.1.
When resizing any portion of the common vent system, the common vent system should be resized to approach the
minimum size as determined using the appropriate tables in Appendix G in the National Fuel Gas Code, ANSI Z 223.1
