Installations must comply with:
Local, state, provincial, and national codes, laws, regulations and
ordinances.
National Fuel Gas Code, ANSI Z223.1 /NFPA 54 – latest edition.
Standard for Controls and Safety Devices for Automatically Fired
Boilers, ANSI/ASME CSD-1, when required.
National Electrical Code.
For Canada only: Natural Gas and Propane Installation Natural
Gas and Propane Installation CAN/CSA B149.1 or B149.2 Instal-
lation Code, CSA C22.1 Canadian Electrical Code Part 1 and any
local codes.
The Ultra boiler gas manifold and controls met safe
lighting and other performance criteria when boiler
underwent tests specifi ed in ANSI Z21.13 — latest edi-
tion.
Before locating the boiler, check:
1. Check for nearby connection to:
System water piping
Venting connections
Gas supply piping
Electrical power
Condensate drain
2. Check area around boiler. Remove any combustible materials,
gasoline and other fl ammable liquids.
Failure to keep boiler area clear and free of combustible
materials, gasoline and other fl ammable liquids and
vapors can result in severe personal injury, death or
substantial property damage.
3. The Ultra boiler must be installed so that gas control system com-
ponents 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 " from combustible materials.

Wall mounti ng option
1. Ultra boilers can be wall mounted (using special wall
mount kit) or fl oor mounted.
for clearance to combustible surfaces.
2. Boilers can be wall mounted ONLY if using the optional
