GAS-FIRED WATER BOILER SERIES 2 — Boiler Manual
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
•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 edition.
Before locating the boiler, check:
1.Check for nearby connection to:
•System water piping
•Venting connections
•Gas supply piping
•Electrical power
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 Ultra 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.
•
•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 0.20" from combustible materials.
3.See Figure 1 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.
