Figure 1 Clearances required
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 Ultra boiler gas manifold and controls met safe
lighting and other performance criteria when boiler
underwent tests specified in ANSI Z21.13 — latest edi-
tion.
Before locating the boiler, check:
Check for nearby connection to:1.
System water piping•
Venting connections•
Gas supply piping•
Electrical power•
Condensate drain•
Check area around boiler. Remove any combustible materials, 2.
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.
The Ultra boiler must be installed so that gas control system com-3.
ponents are protected from dripping or spraying water or rain
during operation or service.
If new boiler will replace existing boiler, check for and correct 4.
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
Hot water pipes — at least ½” from combustible materials.1.
Vent pipe — at least 2. C\zn” from combustible materials.
See 3. Figure 1 for other clearance minimums.
Clearances for service access
See 1. 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.
Wall mounting option
Ultra boilers can be wall mounted (using special wall 1.
mount kit) or floor mounted. No clearance is re-
quired at the rear of the unit
, either for service or
for clearance to combustible surfaces.
Boilers can be wall mounted ONLY if using the optional 2.
wall-mount kit available from Weil-McLain. See page 46
for instructions.
