Before Installing Boiler

Installations must comply with:

•U.S.

—State and local plumbing, heating and electrical codes.

—National codes where applicable.

•Canada

—Canadian Standards Association, CSA B139, Installation Code for Oil-Burning Equipment.

—CSA C22.1 Canadian Electrical Code Part One.

—Applicable local or provincial codes.

Before selecting boiler location:

•Check for nearby connections to:

—System water piping.

—Chimney. See pages 12-13. Boiler can be top or back vented.

—Combustion and ventilation air supply. See page 5.

—Oil supply. See page 22 for oil line routing.

—Electrical power.

•Check area around boiler. Remove any combustible materials, gasoline and other flammable liquids.

Provide clearances around boiler (see FIGURE 1):

Jacket cap must be in place on boiler to avoid requiring an 18"

minimum clearance from back or top of boiler to combustible material.

•Minimum clearances from vent pipe to combustible material:

6 inches — Type “L” doublewall vent*

18 inches — Singlewall vent*

Flue pipe clearances must take precedence over jacket clearances.

•Recommended service clearances:

24 inches — Front and top

6 inches — Left side, back and right side Δ 12 inches — Right side for burner door

swing radius Δ

•Special close clearances (alcove, closet, under counters, etc.) — see Appendix, pages 25-27.

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.
