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

Before installing boiler
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.

Boiler foundation
Table 1
Boiler foundation (see Figure 3)
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. Non-level conditions exist.
