Recommended SERVICE clearances
(Fig. 1a)
1. Provide clearances for cleaning and servicing the boiler and for
access to controls and components. See Figure 1a for recommen-
dations.
2. Provide at least screwdriver clearance to jacket front panel screws
for removal of front panel for inspection and minor service. If
unable to provide at least screwdriver clearance, install unions and
shutoff valves in system so boiler can be moved for servicing.
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.
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.
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:
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.
Minimum foundation width:
CGi-25/3 12" CGi-6 21"
CGi-4 15" CGi-7 24"
CGi-5 18" CGi-8 27"
