WARNING - Failure to adhere to the guidelines on this page can result in severe personal injury, death or substantial property damage.

Boiler Service and Maintenance:

• To avoid electrical shoci, disconnect electrical supply before performing maintenance.
• To avoid severe burns, allow boiler to cool before performing maintenance.
• You must maintain the boiler as outlined in this manual and have the boiler started up and serviced at least annually by a qualified service technician to ensure boiler system reliability.

Boiler Operation:

• Do not block flow of combustion or ventiliation air to boiler. This boiler is equipped with a cont4rol which will automatically shut down the boiler should air or vent be blocked. If vent or air blockage is easily accessible and removable, remove it. The boiler should attempt to restart. If blockage is not obvious or cannot be removed, have the boiler and system checked by a qualified service technician.
• Do NOT allow contaminated air to enter the boiler air inlet pipe. See further for details.
• Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrial supply to boiler. 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 has been under water.

Boiler Water:

• Have boiler water chemistry checked at least annually by a qualified service technician.
• 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". Serious damage to boiler, personnel and/or property may result.
• Continual fresh makeup water will reduce boiler life. Mineral build-up in boiler heat exchanger reduces heat transfer, overheats the metal, and causes heat exchanger failure. Addition of oxygen can cause interal corrosion in system components. Leaks in boiler or piping must be repaired at once to prevent makeup water.
• Do not add cold water to hot boiler. Thermal shock can cause boiler heat exchanger to crack.

Prevent combustion air contamination:

WARNING: If the boiler combustion air inlet is located in any area likely to cause contamination, or if products which would contaminate the air cannot be removed, you must have the combustion air and vent re-piped and terminated to another location. Contaminated combustion air will damage the boiler, resulting in possible severe personal injury, death or substantial property damage.

Do not operate an Ultra boiler if its combustion air inlet is located in a laundry room or pool facility, for example. These areas will always contain hazardous contaminants.

Pool and laundry products and common household and hobby products often contain flourine or chlorine compounds. When these chemicals pass through the boiler, they can form strong acids. The acid can eat through the boiler wall, causing serious damage and presenting a possible threat of flue gas spillage or boiler water leakage into the building.

Please read the information listed below. If contaminating chemicals will be present near the location of the boiler combustion air inlet, have your installer pipe the boiler combustion air and vent to another location, per the Boiler manual.

Products to avoid:

• Spray cans containing chloro/fluorocarbons
• Permanent wave solutions
• Chlorinated waxes/cleaners
• Chlorine-based swimming pool chemicals
• Calcium chloride used for thawing
• Sodium chloride used for water softening
• Refrigerant leaks
• Paint or varnish remover
• Hydrochloric acid / muriatic acid
• Cements and glues
• Antistatic fabric softeners used in clothes dryers
• Chlorine-type bleaches, detergents, and cleaning solvents found in household laundry rooms
• Adhesives used to fasten buildings products and other similar products

 Areas likely to have contaminants

• Dry cleaning/laundry areas and establishments
• Swimming pools
• Metal fabrication plants
• Beauty salons
• Refrigeration repair shops
• Photo processing plant
• Auto body shops
• Plastic manufacturing plants
• Furniture refinishing areas and establishments
• New building construction
• Remodeling areas
• Garages with workshops

Check Boiler Area

WARNING: To prevent potential of severe personal injury, death or substantial property damage, eliminate all materials discussed below from the boiler vacinity and the vicinity of the boiler combustion air inlet.  If contaminants are found:

• Remove products immediately from the area.  If they have been there for an extended period, call a qualified service technician to inspect the boiler for possible damage from acid corrosion.
• If products cannot be removed, immediately call a qualified service technician to re-pipe vent and air piping and locate vent termination/air intake away from contaminated areas.

Combustible/flammable materials: Do NOT store combustible materials, gasoline or any other flammable vapors or liquids near the boiler. Remove immediately if found.

Air contaminants: Products contraining chlorine or fluorine, if allowed to contaminate the boiler intake air, will cause acidic condensate in the boiler. This will cause significant damage to the boiler if allowed to continue. Read the list of potential materials listed on this manual. If any of these products are in the room from which the boiler takes its combustion air, they must be removed imediately or the boiler combustion air (and vent termination) must be relocated to another area.

Check air openings:

1. Verify that combustion and ventilation air openings to the boiler room and/or building are open and unobstructed.
2. Verify that the boiler vent discharge and air intake are clean and free of obstructions.
3. Remove any debris on the air intake or flue exhaust openings.
4. If removing the debris does not allow the boiler to operate correctly afterwards, contact your qualified service technician to inspect the boiler and vent/air systems.

Check The pressure/temperature gauge:

1. Make sure the pressure reading on the boiler pressure/temperature gauge does not exceed 25 psig.
2. Contact a qualified service technician if problem persists.

CALL FRANCIS PLUMBING & HEATING 613-224-0041

Verify boiler front door is secure:

1. Visually inspect boiler front door to be sure it is sealed all around its perimeter. Verify that the two lower thumb screws are tight.

WARNING: Reinstall the jacket front door after servicing. The boiler front door must be securely fastened to the boiler to prevent boiler from drawing air from inside the boiler room.  This is particularly important if the boiler is located in the same room as other appliances. Failure to keep the door securely fastened could result in severe personal injury or death. Contact your installer or tecnician immediately if the dront door does not correctly fit in place or if the door gaskets are damaged.
