DANGER
• Do not attempt to operate this boiler on LP gas without converting it using the proper conversion kit.
• Do not attempt to convert this boiler to LP gas without the use of a combustion analyzer.
• Failure to follow the conversion instructions will result in operation of the boiler at unsafe Carbon
Monoxide (CO) levels and may result in personal injury or loss of life. Improper conversion may also
result in unreliable operation, resulting in property damage.
• Before attempting to operate this boiler at altitudes above 2,000 ft., follow instructions shown in
Appendix A of this manual.
NOTICE
This product must be installed by a licensed plumber or gas fitter when installed within the
Commonwealth of Massachusetts. See Appendix B for additional important information about installing
this product within the Commonwealth of Massachusetts.
IV. Locating the Boiler
1. Observe the minimum clearances shown in Figure 4.1. These clearances apply to combustible construction as well as
non-combustible walls, floors, ceilings and doors.
2. Note the recommended service clearances in Figure 4.1. These service clearances are recommended, but may be reduced
to the combustible clearances provided:
a. Access to the front of the boiler is provided through a door.
b. Access is provided to the condensate trap located beneath the boiler.
Note that servicing the boiler will become increasingly difficult as these service clearances are reduced.
3. Observe the following clearances from piping to combustible construction:
Non-concentric vent (exhaust): ¼" (6mm)
Air intake piping: 0"
Hot water piping: ¼" (6 mm)
4. The relief valve and gauge must be installed in the location shown in Figure 2.1 and must be in the same space as the
boiler.
5. The boiler should be located so as to minimize the length of the vent system.
6. The combustion air piping must terminate where outdoor air is available for combustion and away from areas that will
contaminate combustion air. Avoid areas near chemical products containing chlorine, chloride based salts, chloro/fluoro
carbons, paint removers, cleaning solvents and detergents.
