User’s Information Manual
Please read before proceeding
The Knight Boiler Installation and Operation Manual along with the Knight Boiler Service Manual are for use only by a qualified heating installer/service technician. Refer only to this User’s Information Manual for your reference. Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury (exposure to hazardous materials) or loss of life. Installation and service must be performed by a qualified installer, service agency or the gas supplier (who must read and follow the supplied instruction before installing, servicing, or removing this boiler. This boiler contains materials that have been identified as carcinogenic, or possibly carcinogenic, to humans).
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 electric shock, disconnect electrical supply before performing maintenance.
• To avoid severe burns, allow boiler to cool before performing maintenance.
Boiler operation –
• Do not block flow of combustion or ventilation air to
the boiler. This boiler is equipped with a control 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.
• Should overheating occur or gas supply fail to shut off,
do not turn off or disconnect electrical supply to the 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.
The possible damage to a flooded appliance can be extensive and present numerous safety hazards. Any appliance that has been under water must be replaced.
Boiler water –
• 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 the 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 the boiler, personnel, and/or property may result.
• Continual fresh make-up water will reduce boiler life.
Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen carried in by makeup water can cause internal corrosion. Leaks in boiler or piping must be repaired at once to prevent makeup water.
Freeze protection fluids –
• NEVER use automotive antifreeze. 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.
When calling or writing about the boiler – Please have the boiler model and serial number from the boiler rating plate.
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.
Factory warranty (shipped with unit) does not apply to units improperly installed or improperly operated.

Table 1 Corrosive Contaminants and Sources
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.
Pool and laundry products and common household and hobby products often contain fluorine 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 in Table 1. 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 Knight Boiler Installation and Operation Manual.
