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.
