• Canada
— Canadian Standards Association,
CSA B139, Installation Code for
Oil-Burning Equipment.
— CSA C22.1 Canadian Electrical Code Part One.

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.
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.
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 ∆
12 inches — Right side for burner door
swing radius ∆
• Special close clearances (alcove, closet, under
counters, etc.) — see Appendix, pages 25-27.
