BEFORE YOU START

Complete all of the following prior to installing the boiler.

A.Check to be sure you have selected the right size boiler with the proper capacity. The I=B=R rating of the boiler selected should be greater than or equal to the calculated peak heating load (heat loss) for the building or area(s) served by the boiler and associated hot water heating systems. See boiler rating and capacity table previously listed in this manual. Any heat loss calculations used should be based on approved methods.

B.Boiler rdust be supplied with the proper oil supply and oil piping, sufficient fresh combustion air, and a suitable electrical supply.

C.Boiler must be connected to a suitable venting system and a piping system adequate to distribute the heating load. D. A thermostat must be properly located and installed for control of the heating system.

If there are any doubts as to the various requirements, check with local authorities and obtain professional help where

needed. The OPERATING INSTRUCTIONS, FINAL CHECKS AND ADJUSTMENTS, and MAINTENANCE sections in this manual are vital to the proper and safe operation of the heating system. Take the time to be sure they are all done.

LOCATING THE BOILER

1.Place the boiler in a location centralized with the piping system and as close to the chimney as possible.

2.The boiler must be level. If necessary use metal shims beneath the boiler's feet.

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

4.Maintain clearances for fire safety as well as servicing. An 18" clearance must be maintained at a side where passage is required for access to another side for cleaning, servicing, inspection, or replacement of any parts that normally may require such attention. Boilers must be installed at least 6" from combustible material on all sides and above. Allow at least 24" front clearance for servicing.

5.Fresh air for combustion must be available at the front of the boiler. Fresh air for ventilation must be available to the front AND rear of the boiler. Air passages must be free of obstructions at all times. Ventilating and combustion air must enter boiler room without restrictions.

6.The floor supporting the boiler must be non-combustible and sufficiently stable. If it is combustible, place the boiler on 2" concrete patio blocks or 2" Cladlite TM Pad. The blocks or pad must be under the entire boiler to protect the floor.

7.Be sure installation is in accordance with the requirements of the local authorities having jurisdiction. Compliance with these regulations is required. In the absence of local codes, follow NFPA 31 - Installation of Oil Burning Equipment, latest revision.
