Codes –
The equipment shall be installed in accordance with those
installation regulations in force in the local area where the
installation is to be made. These regulations shall be carefully
followed in all cases. Authorities having jurisdiction shall be
consulted before installations are made. In the absence of
such requirements, the installation shall conform to the latest
edition of the National Fuel Gas Code, ANSI Z223.1. Where
required by the authority having jurisdiction, the installation
must conform to American Society of Mechanical Engineers
Safety Code for Controls and Safety Devices for Automatically
Fired Boilers, ASME CSD-1. All boilers conform to the latest
edition of the ASME Boiler and Pressure Vessel Code, Section
IV. Where required by the authority having jurisdiction,
the installation must comply with the Canadian Association
Code, CAN/CGA- B149.1 and/or local codes.
This appliance meets the safe lighting performance criteria
with the gas manifold and control assembly provided as

Boiler water –
Thoroughly flush the system to remove debris. Use an approved
pre-commissioning cleaner (see Start-Up Section), without the
boiler connected, to clean the system and remove sediment.
The high-efficiency heat exchanger can be damaged by build-up
or corrosion due to sediment.
NOTE: Cleaners are designed for either new systems or
pre-existing systems. Choose accordingly.
Prevention of freezing –
Heat exchangers and headers damaged by freezing are not
covered by warranty.
See Section 6, Start-Up - Freeze Protection for more information.
