Before Installing And When Servicing The Boiler; During Boiler Operation; Boiler Water; Freeze Protection Fluids - Baxi DUO-TEC COMPACT 30 GA Notice D'installation Pour L'installateur

WARNING
Failure to comply with the above could result in severe personal injury, death or substantial property damage. Failure
to adhere to the guidelines on this page can result in severe personal injury, death or substantial property damage.
WARNING
If the information in these instructions is not followed exactly, a fire or explosion may result causing property damage,
personal injury or death.
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier or your licensed qualified service technician from a neighbor's phone. Follow the
gas supplier's or licensed qualified personnel's instructions.
• If you cannot reach your gas supplier or your licensed qualified service technician, call the fire department.
WARNING
Baxi recommends the use of a carbon monoxide detector in conjunction with the Baxi boiler product line. When
installing a carbon monoxide detector, the manufacturer's instructions of the carbon monoxide detector must be
followed in their entirety. It is recommended to use a carbon monoxide detector in compliance with a nationally
recognised standard such as ANSI/UL 2034-2002 in the United States and CSA 6.19-01 in Canada.
WARNING
Installation and service must be performed by a gas supplier or a licensed qualified installer / service Technician. If
overheating occurs or the gas supply fails to shut off, do not turn off or disconnect the electrical supply to the pump.
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 which bas been under water.

BEFORE INSTALLING AND WHEN SERVICING THE 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 intake air to boiler.
• If overheating occurs or gas supply fails 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 recommend 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.
• Ensure piping in the heating system has an oxygen barrier.

FREEZE PROTECTION FLUIDS

CAUTION
Never use automotive or standard glycol antifreeze, or 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.
