COMMERCIAL CONDENSING GAS

Prepare boiler location

Installations must comply with:
Local, state, provincial, and national codes, laws, regulations and
ordinances.
National Fuel Gas Code, ANSI Z223.1 – latest edition.
Standard for Controls and Safety Devices for Automatically Fired
Boilers, ANSI/ASME CSD-1, when required.
National Electrical Code.
For Canada only: B149.1 or B149.2 Installation Code, CSA C22.1
Canadian Electrical Code Part 1 and any local codes.
The SlimFit boiler gas manifold and controls met safe
lighting and other performance criteria when boiler un-
derwent tests specified in ANSI Z21.13 — latest edition.

Before locating the boiler, check:

1. Check for nearby connection to:
System water piping
Venting connections
Gas supply piping
Electrical power
Location of drain for condensate
2. Check area around boiler. Remove any combustible materials,
gasoline and other flammable liquids.
Failure to keep boiler area clear and free of combustible
materials, gasoline and other flammable liquids and
vapors can result in severe personal injury, death or
substantial property damage.
3. The SlimFit boiler must be installed so that gas control system
components are protected from dripping or spraying water or rain
during operation or service.
4. If new boiler will replace existing boiler, check for and correct
system problems, such as:
System leaks causing oxygen corrosion or heat exchanger cracks
from hard water deposits.
Incorrectly-sized expansion tank.
Lack of freeze protection in boiler water causing system and
boiler to freeze and leak.

Provide clearances:

Clearances from combustible materials
1. Hot water pipes — at least ½" from combustible materials.
2. Vent pipe — at least ³⁄₁₆" from combustible materials.
3. See Figure 2 for other clearance minimums.
Clearances for service access
1. See Figure 1 for recommended service clearances. If you do not
provide minimum clearances shown, it might not be possible to
service the boiler without removing it from the space.
