1. INTRODUCTION
The Condensing boiler is a wall hung, fan assisted room-sealed combination boiler.
The boiler, providing both central heating and domestic hot water for the Utica Boiler MAC-150 model and only heating for the
Utica Boiler MAH - 1 25 model at street pressure, is designed for use with a fully pumped, sealed and pressurized heating
system. The boiler is supplied with a pump, diverter valve, pressure relief valve, and pressure gauge fully assembled and tested.
As supplied, the boiler will automatically modulate to provide central heating outputs between 19,108 and 112,601 Btu/h (5.6
and 33.0 kW).
The maximum output available for domestic hot water is 136, 000 btu/h (40 kW), capable of providing 3. 5 (U.S.) gpm ( 13.2 litres/
min) with a temperature rise of 70°F/39°C for the Utica Boiler MAC-1 50 .
WARNING
It is the law that all gas appliances are installed by a competent person. It is in your own interest and that of safety to
ensure that the law is complied with.
• In the United States, the installation must conform to the requirements of the authority having jurisdiction or, in the absence of
such requirements, to the National Fuel Gas Code, ANSI Z223.1/NFPA 54. Where required by the authority having jurisdiction,
the installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME
CSD-1. Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the
boiler when the boiler underwent tests specified in ANSI Z21.13-latest edition.
• In Canada, the installation must conform with CGA B149.1 INSTALLATION CODE and/or local installation Code, plumbing or
waste water codes and other codes as applicable.
• Clearances from and protection of combustible material.
• Manufacturer's instructions must NOT be taken in anyway as over-riding statutory obligations.
