Steffes 7140 - Manual (Page 14)

If the Comfort Plus Commercial Hydronic is installed in an area where radiant heat coming from the system is
undesired or where room temperatures may reach 85° Fahrenheit or greater, it is strongly recommended to install
a Static Heat Recovery unit or Air Handler. Refer to pages 2.01-2.02 for information on these options.
In addition to the physical space requirements, the weight of the Comfort Plus Commercial Hydronic must be
taken into consideration when selecting the installation surface. A level concrete floor is the best installation
surface, but most well supported surfaces are acceptable. If unsure of floor load capacity, consult a building
contractor or architect.
Special requirements need to be considered if placing the system in a garage or other area
where combustible vapors may be present. Consult local, state, and national codes and regula-
tions to ensure proper installation. An 18" stand (Order Item #1301585) is available to elevate
the system.
INITIAL SET-UP
Step 1 Remove the Information Package from the outside of
the shipping box and unpackage the Comfort Plus
Commercial Hydronic heating system.
Step 2 Move the heating system into its installation location.
The Comfort Plus Commercial Hydronic is capable of
fitting through a 30" doorway (minimum) without
disassembling. If it is necessary to disassemble the
system, refer to the disassembly instructions (Page
A.03) in this manual.
Step 3 Once in place, adjust the leveling legs on the bottom of
the system as necessary to prevent rocking. If not
placed properly the system may bend or twist during the
brick loading process, making element and brick core
temperature sensor installation difficult.
Step 4 Remove the painted front panel of the brick storage
cabinet by removing the sheet metal screws along the top, bottom, and sides of the panel. Detach by
pulling the bottom of the panel forward and down.
Step 5 Locate the element wiring harnesses and the two brick core temperature sensors behind the front panel
and disconnect them from their shipping position. Carefully position them to avoid damage during brick
loading.
Step 6 Remove the galvanized front panel and set it aside.
Step 7 Carefully lift the two insulation blankets, one at a time starting at the bottom, and drape them over the
top of the system.
Use face mask, gloves, and long sleeved garments when handling insulation materi-
als in compliance with generally accepted safety practices.
Step 8 Remove the front air channel by pulling out at the top.
Step 9 Remove the heating elements from inside the brick core cavity.
To ensure proper operation, read and
follow installation instructions carefully.
