CODES

The equipment MUST be installed in
accordance with those installation regulations
in effect in the local area where the installation
is to be made. These MUST be carefully
followed in all cases. Authorities having
jurisdiction MUST be consulted before
installations are made. In the absence of such
requirements, the installation MUST 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, No. (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 Gas Association Code, CAN/CGA-
B149.1 and/or B149.2 and or local codes.

LOCATION OF UNIT

Locate the unit so that if water connections
1.
should leak, water damage will not occur.
When such locations cannot be avoided, it
is recommended that a suitable drain pan,
adequately drained, be installed under the
unit. The pan MUST NOT restrict
combustion airflow. Under no circumstances
is the manufacturer to be held responsible
for water damage in connection with this
unit or any of its components.
