Install Instructions

Drilling Joists
For standard installation, joists should be drilled 3" below floor
sheathing, spaced according to the calculations you made.
However, there are some exceptions to this rule:
• When the joists are manufactured "truss joists," refer to the joist
manufacturer’s instructions regarding drilling in the joist web before
automatically drilling 3" below sheathing, or 8" from each end of the
joist span.
• Whenthejoistsare8"orlessindepth,youmaystilldrill3"belowoor
sheathing, but you must use a thinner, special insulation product. This
ensures the insulation does not touch the tubing and the Ultra-Fins.
Attaching Ultra-Fins
Attaching the Ultra-fins is easy, just follow these steps:
Insulating the Ultra-Fin System
In all circumstances, the joist space below the Ultra-Fin System
must be insulated.
The type and thickness of insulation material will vary according to
two factors:
1) The depth of the joists.
There must be a minimum of 2" of dead air space between the Ultra-
Fins and the insulation, and another minimum 2" between the Ultra-
fins and the floor sheathing. (Minimum 4" total air space is required,
and6"isrecommendedwhereverpossible.)
2) Whether or not the room/space below the joists is classified
as heated and enclosed (e.g. interior room) or unheated and
exposed (e.g. garage or carport).
Refer to the following diagrams for specifications and instructions on
insulating the Ultra-Fin System under a variety of circumstances.
Pulling Tubing
If you choose to drill the joists and run the tubing through the joists (e.g.
Ultra-Fin High Temp installation), use the following procedure to pull the
tubing through the holes:
• For each heating zone, feed one continuous length of ½" tubing
(5/8" O.D.) through the holes and back to the supply/return manifold.
• Onturnsagainstoutsidewalls,bendtubingintoaatD-shapesothat
it can take one Ultra-Fin. Always allow 10" of straight tubing on the
D-bend.
• On turns against inside walls, bend the tubing into a V-shape and
clamp it to the side of the box joist, so it can take two Ultra-Fins. Make
sureyouallow10"ofstraighttubingoneachsideoftheV-bend.
• Connecttheendsofthetubingcircuittothesupply/returnmanifold.

INSTALLATION TIP
+
You can save time pulling tubing by starting to pull your coil
from the middle of each zone/room. (See diagram below)
When you have finished pulling the tubing through one half
of the zone and back to the supply/return manifold, measure
the length of tubing you need to complete the remaining half
of the zone and its return run to the manifold.
Roll that length off the tubing coil and cut it, allowing some
extra length to be safe. (See diagram below)

Design a Tubing & Fin Layout
After you know how much material you need, you are ready to design
an installation layout for the tubing and aluminum Ultra-Fins.
NOTE: Some sample layouts for High Temp installation are shown
on the back of this brochure.
A. Calculate the Number of Heating Zones
Look at the overall square footage of the home and the total number
of rooms. How many rooms does the home have? With the exception
of small interior spaces such as hallways and powder rooms, this is
thenumberofheatingzonesyouwillwanttoinstall.
B. Sketch the Floor Plan

C. Measure the Joist Spacing
The joist spacing in the oor system will usually be 12", 16" or 19".
In rare instances, it could be 24". When you have determined the joist
spacing,youarereadytocalculatethetubingspacingforeachzone.
D. Decide if you will run the tubing parallel to the joists or
perpendicular across the joists.
You have two options when you hang the tubing. You can either run
the tubing parallel to the joists using SnakeHangers
™
or you can drill
the joists and run the tubing laterally through the joists.
Read the following sections for Ultra-Fin HIGH TEMP or
MODULATING to see which way is right for you.

NOTE
+
Ultra-Fin highly recommends having separate heating
zones (tubing circuits) for each room in the house.
If you run the tubing through
the joists, it's still easier to start
pulling in the middle of the room
