Operating Conditions
Comments – Detailed Information
Boiler room temperature
+40 to +104 °F
Relative humidity
max. 90 %
No condensate or dampness in boiler room.
Dust
–
No excess amounts of dust should be present in the boiler room, e.g.:
–
No sheet rock or construction dust.
The available combustion air can not contain dust or other particles/ use of an air
filter might be needed, e.g.:
–
Combustion air from nearby roads with high dust levels.
–
Combustion air from nearby production facilities such as chemical plants &
shops.
–
Airborne particulates.
Halogenated Hydrocarbons

The boiler room and especially the air inlet openings for combustion air must be
kept free from animals entering by means of grills.
Fire Protection
–
Maintain proper clearances to combustible materials as required per local code.
Maintain a minimum distance of 16”. Do not store flammable materials near the
boiler.
Flood Zone Conditions
–
Separate the fuel supply and electrical power supply from the boiler during flood
conditions. Replace the boiler components such as insulation, electrical and con-
trol components afterwards.
