Recommended SERVICE clearances

(Fig. 1)

1.Provide clearances for cleaning and servicing the boiler and for access to controls and components. See Figure 1 for recommenda- tions.

Figure 1

Recommended

SERVICE clearances

(see WARNING

below)

If any clearance is less than in Figure 1, provide openings for combustion and ventilation air located on the wall or door opposite the boiler FRONT (see Figure 2).

These openings must be located as shown in Figure 2 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 10 for definition), the air openings must connect directly to outside or the building must have air openings to the outside as specified on page 10.

If clearances are equal to or greater than Figure 1, 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. 2)

Never install the boiler in a space with clear- ances less than the minimum clearances shown in Figure 2. Failure to comply can result in severe personal injury, death or substantial property damage 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.

Figure 2 Required MINIMUM clearances

Flooring

The CGi boiler is approved for installation on combustible flooring, but must never be installed on carpeting.

Do not install boiler on carpeting even if foundation is used. Fire can result, causing severe personal injury, death or substantial property damage.

Foundation

1.Provide a solid brick or minimum 2-inch thick concrete foundation pad if any of the following is true:

•floor can become flooded.

•the boiler mounting area is not level.

2.Minimum dimensions are 25” length by:

Minimum foundation width

CGs-3	15”	CGs-5	21”
CGs-4	18”	CGs-6	24”

Residential garage installations

Take the following special precautions when installing the boiler in a residential garage. If the boiler is located in a residential garage, per ANSI Z223.1:

•Mount the boiler a minimum of 18 inches above the floor of the garage to assure the burner and ignition devices will be no less than 18 inches above the floor.

•Locate or protect the boiler so it cannot be damaged by a moving vehicle.
