If boiler is part of a planned heating system, locate it as close as possible to where it is shown on plan. If boiler is to be part of an existing system,

it is usually best to put it where the old one was. If location is to be changed, additional materials as well as an adequate base will be required.

The following rules apply:

1. The boiler must be level.

2. Use a raised base if floor can become wet or damp.

3. These boilers must have a non-combustible base if installed on a combustible floor. Two-in. concrete patio blocks or a 2-in. Cladlite™ pad

may be used.

4. The vent pipe connection should be as short as possible.

5. Maintain clearances for fire safety as well as servicing. Refer to Fig. 2 for minimum clearances. An 18-in. clearance must be maintained

at a side where passage is required to access another side for cleaning, servicing, inspection, or replacement of any parts that normally may

require such attention. Boilers must be installed at least 6 in. from combustible materials on all sides and above. Allow at least 24-in. front

clearance for servicing. Allow at least 18-in. right-side clearance for servicing boilers equipped with a tankless coil.

6. FRESH AIR for combustion must be available at front of boiler. FRESH AIR for ventilation must be available to front AND rear of boiler.

Air passages must be free of obstructions at all times. Ventilating and combustion air must enter boiler room without restrictions.

7. Be sure installation is in accordance with the requirements of local authorities having jurisdiction. Compliance with these regulations is

required. In the absence of local codes, follow NFPA 31—Installation of Oil Burning Equipment.
