Recommended

SERVICE clearances

(see WARNING

below)

If any clearance is less than in Figure 1a, pro- vide openings for combustion and ventilation air located on the wall or door opposite the boiler FRONT (see Figure 1b).

These openings must be located as shown in Figure 1b to provide proper air flow around the boiler. The free area of each opening (after deducting for louvers) must be at least one square inch per 1,000 Btuh of boiler input. If the building is of unusually tight construction (see page 11 for definition), the air openings must connect directly to outside or the building must have air openings to the outside as specified on page 11.

If clearances are equal to or greater than Figure 1a, see pages 10 and 11 for location and sizing of combustion air openings.

Failure to comply can result in severe personal injury, death or substantial property damage and reduced boiler life.

Required MINIMUM clearances (Fig. 1b)

Never install the boiler in a space with clear- ances less than the minimum clearances shown in Figure 1b. Failure to comply can result in severe personal injury, death or substantial property dam- age and reduced boiler life.

1.Hot water pipes: at least ¹⁄₂ inch from combustible material.

2.Single-wall vent pipe: at least 6 inches from combustible mate- rial.

3.Type B double-wall metal vent pipe: refer to vent manufacturer’s recommendation for clearances to combustible material.
