Before selecting boiler location
1.Check for nearby connections to:
a.Fuel supply
b.Electrical power
c.System water or steam piping
d.Venting systems - see page 31
e.Combustion and ventilation air supply — see "Provide combustion and ventilation air supply openings" on page 4.
2.Check area around boiler. Remove any combustible materials, gasoline and other flammable vapors and 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 and substantial property damage.
Lay a foundation, if needed:
Floor construction and condition must be suitable for weight of boiler when filled with water. See page 34 for approximate boiler operating weight.
A level concrete or brick foundation (constructed per Table 1 and Figure 1) is required when:
1.A floor could possibly become flooded.
2.

Provide clearance around boiler
•Provide minimum clearances to combustible materials:
1.Singlewall vent pipe – 18 inches.
2.Doublewall vent pipe – refer to vent pipe manufacturer's recommendations for vent pipe clearances.
3.Boiler top — 24 inches.
4.Boiler front — 48 inches.
5.Boiler flue — 9 inches.
6.Boiler rear — 9 inches.
7.Boiler sides — 6 inches.
•Boiler may be installed on combustible flooring.
•See pages 34 and 35 for boiler dimensions.
Flue pipe/breeching clearances take precedence over jacket clearances.
•Left side — for cleaning and tankless heater removal – 34 inches.
•Allow sufficient space on remaining sides for cleaning, servicing and burner installation. See burner literature for length and recommended service clearances.
