16 Installing the Boiler
2.2 Choosing an Installation
Location
When choosing an installation location, you must
ensure that the location provides adequate clearance
for the boiler, adequate venting and drainage
options, and sufficient access to gas, water, and
electrical supplies. Carefully consider the following
factors when choosing an installation location:
Compliance Requirements
Local, state, provincial, and national codes, laws,
●
regulations, and ordinances.
National Fuel Gas Code, ANSI Z223.1-latest edition.
●
Standard for Controls and Safety Appliances for
●
Automatically Fired Boilers, ANSI/ASME CSD-1,
when required.
National Electrical Code.
●
For Canada only: B149.1 Installation Code, CSA
●
C22.1 Canadian Electrical Code Part 1, CSA-B214-12
Installation code for hydronic heating systems, and
any local codes.
Access to Utilities
Water – the installation location should be near
●
where the domestic water supply enters the building.
Gas – the installation location should be near where
●
the gas supply enters the building.
Electricity – the installation location should be near
●
where the electrical supply enters the building.
Humidity and Contact with Water
When installing the boiler, avoid places with
excessive humidity. The boiler has electric gas
ignition components. Moisture can get inside
the boiler and damage the ignition system. The
boiler must be installed in a way to ensure that
the gas ignition system components are protected
from water (dripping, spraying, rain, etc.) during
operation and service.
