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.
Figure 1 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.
