RITTLING RADIATORS
Horizontal Units
Installation, Operation & Maintenance
Radiators with Fins on back side of panel (PRF &4.
PR3F): With the radiator face down, attach each PR
CLIP to the fins at the stud location. With the radiator
still face down, thread the leveling bolts (5/16”
carriage bolts) into the
bottom threaded positions
with a crescent wrench.
Once the bolts have cleared
the paint away, they should
turn easily by hand. Hang
the panel (installed on wall
in step 3) onto the brackets
to determine if the leveling
bolts are properly adjusted.
Check that the panel is
level.
Radiators without Fins on back side of panel (PR,5.
PR2 & PR2F): With the radiator face down, thread
the leveling bolts (5/16” carriage bolts) into the bottom
threaded positions with a crescent wrench. Once the
bolts have cleared the paint away, they should turn

supply and return fittings into the connections on the
radiator. The sealing tape or pipe dope used is the
installer’s choice – make sure the connections are leak
tight. One quarter of a turn past hand tight is usually
sufficient. Each radiator needs to be fitted with a 1/8”
air vent prior to startup.
Installation Instructions:
Radiators are boxed together in as few crates as1.
possible. A box of brackets is included as a separate
piece, and it is marked to denote brackets. Inside the
crates, each panel is wrapped
in foam sheeting. Saving this
foam to re-wrap the panel
once it is wall mounted will
protect it from construction
site damage.
Each radiator is tagged with2.
a label that indicates the
project name, model type,
color, connection code, bracket type & quantity and
tag number. Locate each radiator as required.
Carefully place each radiator face down on a smooth3.
level surface (i.e. floor or table). Distribute the brackets
for each radiator. The tag on the radiator indicates the
quantity of brackets. Mount the brackets securely on
wall studs or solid backing with two lag bolts, spacing
them as evenly as possible at 2’ to 4’ apart, with a
bracket at least 12” from each end of the panel. Allow
a minimum of 3” below each panel radiator to facilitate
cleaning and to assure proper output. For baseboard
models, 1” above the floor is permissible with little
loss of heat output.

PED-SM & Pedestal2.
Mounted Radiators: When
using PED-SM, each PED-
SM must line up with a
corresponding leveling
bolt attached to the back
side of the radiator. Using
this spacing as a guide,
securely fasten each floor
post to the floor, using
appropriate fasteners. The
FIN BKT is attached to the PED-SM, and the FIN BKT
to the radiator, as described in step #4 above. The nut
and bolt used to attach the FIN BKT to the PED-SM is
to be supplied by others. A 1/4” bolt a minimum of 1
1/2” long is recommended.
For PR2F & PR3F Pedestal mounting with PED-BM-3.
SQ the pedestals should be arranged so that the end
pedestals sit within 12” of each end of the radiator,
with the remainder spaced evenly along the radiator’s
length. Each pedestal should be securely fastened to
the floor using appropriate fasteners. Radiators sit
on the pedestals, with the “fingers” of the pedestals
sticking up between the fins to provide stability.
Radiators expand a maximum of 0.016 inch per linear4.

the radiator must provide the necessary expansion
compensation.

maximum air, the piping and radiators can be filled
with water. As water fills the system and radiators,
air is forced to the vent fittings. Vent as much air as
possible before turning on the circulating pump(s).
When the system is filled, operate the circulating6.
pump(s) to force the remaining air to the high points
of the system. Turn off the circulating pump(s) to vent
the panels. Each radiator should be individually bled
of air. Once cold venting has been completed, heat the
system to design temperature and repeat the venting
procedure as many times as necessary to remove all air
from the system.

Radiator Operation
Radiators are manufactured in the USA of cold rolled1.
low carbon steel and should be used only in closed
hydronic systems to assure no corrosion of any system
components.
Proper radiator operation depends on adequate flow of2.
water to the panel, which can only be accomplished
when all the system air has been fully vented from the
panels.
Radiators should each be vented, with the system3.
pressurized but in a static state (pumps off). Venting
may need to be done periodically to assure a closed
system.
Flexible piping and elbowed piping are two simple4.
ways to provide the 1/8” to 1/2” (typical) of flexibility
required in expansion situations (usually series
piping).
Rittling Radiators require less flow rate than other5.
hydronic heating products. If flow noise is apparent,
balance the system until the noise is reduced.
For a delta T of 20º F (T supply minus T return), divide6.
the total Btu/hr capacity of the loop by 10,000. This
gives the Flow Rate in gallons per minute (GPM).

systems. Rittling Radiators will provide nice, even
heating whether operated by a simple thermostat to
baseboard loop system, or an advanced boiler reset
controller with motorized mixing valves, constant
circulation and two-pipe distribution.
Radiator Maintenance
Hydronic System Maintenance should include routine1.
checks for piping leaks (usually indicated by frequent
makeup water), and a yearly diagnosis of the system
water pH to evaluate its corrosive potential.
Internal radiator maintenance depends entirely on the2.
system water makeup and proper venting. Hydronic
system additives are available to passivate and protect
against freezing. These additives will not significantly
reduce the output of Rittling Radiators.
External radiator maintenance consists of keeping the3.
surfaces clean, and any paint nicks or deep scratches
painted with touch-up to prevent any surface rust.
Radiators can be repainted after sanding with fine grit4.
paper to dull the high gloss and by wiping with solvent
or a tack rag. Use only oil based enamel paint (alkyd,
acrylic, urethane, epoxy) – do not use latex or lacquer
paint. Use urethane or epoxy enamel for radiators
located in harsh environments. Spray the paint to
achieve an even coating, and let dry completely before
heating the radiator.

PED-SM
The PED-SM floor post is typically used to mount
PR or PRF radiators. Also, PR2F and PR3F radiators
over four tubes tall must also be mounted on PED-
SM floor posts. The ANG BKT (PR & PR2F) or
FIN BKT (PRF & PR3F) wall mounting brackets
supplied with the radiator are bolted to the floor
post, using nuts and bolts supplied by the installer.
The leveling bolt screws into the radiator and rests
against the floor post to level the radiator.
The 3”x3” base has four mounting holes. The
installer supplies the appropriate mounting bolts to
secure the PED-SM base to the floor.
The PED-SM’s height is fixed to provide 3” clearance
under the radiator, unless otherwise specified.
PED-BM-SQ
The PED-BM-SQ pedestal is used to mount PR2F or
PR3F radiators, up to four tubes tall. Radiators over
four tubes tall should not be mounted on PED-BM-SQ
pedestals, because they will be unstable. Mounting
is accomplished by setting the radiator down over
the fingers of the PED-BM-SQ. The bottom tubes
of the radiator rest on the pedestal, while the fingers
protrude up through the fins to stabilize the radiator.
For Radiators without Fins (on the back side of the
panel) – no wall mounting clips should be ordered for
radiators to be mounted on PED-BM-SQ pedestals.
The 3”x3” base has four mounting holes. The
installer supplies the appropriate mounting bolts to
secure the PED-BM-SQ base to the floor.
The PED-BM-SQ’s height is fixed to provide 3”
clearance under the radiator, unless otherwise
specified.
