Local, state, provincial, and national codes, laws, regulations and
ordinances.
National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition.
National Electrical Code ANSI/NFPA 70 – latest edition.
Electrical installation and grounding must be in accordance with
CSA C22.1, Part 1, Canadian Electrical Code, and/or local codes.

The SVF
boiler gas manifold and controls met safe light-
ing and other performance criteria when boiler underwent
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.
TM
3. The SVF
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.
Flooring and foundation
Flooring
TM
The SVF
boiler is approved for installation on combustible flooring,
but must never be installed on carpeting.
Do not install boiler on carpeting even if foundation is
used. Fire can result, causing severe personal injury, death
or substantial property damage.
Foundation
1. The boiler mounting surface must be level and suitable for the load.
2. Provide a solid foundation pad, at least 2 inches above the floor, if
any of the following is true:
floor can become flooded.
the floor is dirt, sand, gravel or other loose material.
the boiler mounting area is severely uneven or sloped.
3. The minimum foundation size is listed in Figure 1.

4. Foundation may be of wood, brick or concrete (minimum 2
inches thick) construction.
5. If flooding is possible, elevate boiler sufficiently to prevent water
from reaching boiler.

Garage installation
Precautions
Take the following special precautions when installing the boiler in
a garage. If the boiler is located in a garage:
Mount the boiler at a height above the floor as specified in
the National Fuel Gas Code - ANSI Z223.1/NFPA 54 –
latest edition for U. S. installations, or Natural Gas and
Propane Installation Code - CAN/CSA B149.1 for Cana-
dian installations.
Locate or protect the boiler so it cannot be damaged by a
moving vehicle.
Ensure that the installation complies with all applicable codes.
