Table 15. Model CFC-E Minimum Required Gas Pressure Altitude Correction
Boiler Room Information
The boiler must be installed on a level non-combustible surface. If the surface is not level, piers or a
raised pad, slightly larger than the length and width of the boiler base dimensions, will make boiler
leveling possible. Installing the boiler on a raised pad or piers will make boiler drain connections
more accessible and will keep water from splashing onto the boiler whenever the boiler room floor is
washed.
Note: The pad or piers must be of sufficient load bearing strength to safely support the operating weight of the boiler and
any additional equipment installed with it. Approximate operating weights are shown in Dimensions and Ratings.
Leveling
Once the boiler is placed, it must be leveled side to side and front to back using the supply and
return nozzles for horizontal and vertical positions. If shims are required to level the boiler, the weight
of the boiler must be evenly distributed at all points of support. The optional adjustable feet may also
be used for leveling.
Clearances
The boiler must be installed so that all components remain accessible; ensure no overhead
obstructions so the burner may be opened. Refer to Figure 25.
Hot Water Piping
Dedicated boiler circulation pumps are not required with the Model CFC-E boiler. As its design is
such that no minimum flow is required, variable speed or on/off pumps may be employed in the
piping scheme.

To obtain minimum required inlet pressure, select altitude of installation and multiply the pressure
shown in Table 13 by the correction factor corresponding to the altitude listed above.
