(“propane”) using a combustion analyzer in accordance with the instructions in Appendix A.
5) Models are not suitable for installation at altitudes above 2000ft.
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,oors,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difcultastheseserviceclearancesarereduced.
3) Observe the following clearances from piping to combustible construction:
Non-concentric vent (exhaust): ¼”
Air intake piping: 0”
Hot water piping: ¼”
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 con-
taminatecombustionair.Avoidareasnearchemicalproductscontainingchlorine,chloridebasedsalts,chloro/uorocarbons,
paint removers, cleaning solvents and detergents.

DANGER
• Do not attempt to operate this boiler on LP gas without converting it in accordance with the
instructions shown in Appendix A.
• Do not attempt to convert this boiler to LP gas without the use of a combustion analyzer.
• Failure to follow the conversion instructions in Appendix A will result in operation of the boil-
er 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.
WARNING
Do not install this boiler at altitudes above 2000ft. Attempting to do so may result in unreliable
operation, property damage, personal injury or loss of life.
