1b Prepare boiler location — clearances
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.
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.

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.

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.
