efore connecting the gas supply, determine the gas type and
pressure for the boiler by referring to the rating plate. Use only the
same gas type indicated on the rating plate. Using a different gas
type will result in abnormal combustion and malfunction of the
boiler. Gas supplies should be connected by a licensed professional
only.
The appliance and its gas connection must be leak tested before
placing the appliance in operation.
This boiler cannot be converted from natural gas to propane or vice
versa without a
N
avien gas conversion kit. Do not attempt a field
conversion of this boiler without a
N
avien gas conversion kit. Doing
so will result in dangerous operating conditions and will void the
warranty.
N
avien, Inc. is not liable for any property damage and
/
or personal injury
resulting from improper conversions.
