5.2 Installation of 30/60° Mounts on Roofs, Walls,

or Ground



IMPORTANT: INSTALLED HEIGHT MUST NOT EXCEED 60 FEET.

CHECK THE ROOF STRUCTURE TO ENSURE PROPER SUPPORT FOR

COLLECTORS, MOUNTING HARDWARE, WIND LOADS, ETC. (STATIC

CALCULATION REQUIRED; IF NECESSARY, CONTACT THE BUILDER).

ALL ROOFING WORK MUST BE CARRIED OUT BY A PROFESSIONAL ROOFING

CONTRACTOR. WHEN WORKING ON ROOFS, OBSERVE ALL RELEVANT

SAFETY REGULATIONS, IN PARTICULAR: “SAFETY REGULATIONS FOR

WORK ON ROOFS” AND “SAFETY AND RECOVERY HARNESSES”V (OR LOCAL

REGULATIONS).

INSTALLERS MUST COMPLY WITH ALL LOCAL, STATE, AND NATIONAL

CODES.

ROPE MAY BE USED TO HOIST COLLECTORS, BUT MUST NEVER BE

ATTACHED TO THE COLLECTORS’ PIPES.

WHEN WORKING ON ROOFS, ALL RELEVANT SAFETY REGULATIONS MUST

BE OBSERVED.

Designers and installers should consider how rainwater, snow, and

ice accumulation is affected by the installation of the collectors and

mounting hardware. Collectors affect the ﬂow of rainwater around

them, so appropriate means for conducting the water away from the

vicinity of the collectors must be provided. Collectors and mounting

hardware are also subject to accumulation of snow and ice in

cold climates. Installations must provide protection to people and

structures below the solar collectors to avoid hazards due to falling

snow and ice as it melts (or is blown off by winds). Installers must

also consider the possibility of snow and ice falling onto collectors

from any structures located above them and provide appropriate

means of protecting them.

Building materials adjacent to solar components must not be

exposed to the elevated temperatures that the collectors can

generate. Exposed components (that can readily be reached) must

be maintained below 140°F or otherwise be insulated/isolated. All

other exposed surfaces that can exceed 140°F should be labeled with

appropriate burn hazard warnings.

Tools Needed:

1. Power drill with 1/4” drill bit. Bits of other sizes are

recommended as well.

2. 11/16” drill bit for corrugated sheet roof installations.

3. Two 17mm wrenches and/or sockets for M10 bolts.

4. Two 15mm wrenches and/or sockets for M10 nuts.

5. Two 7/16” wrenches/sockets for 7/16” and 1/4” nuts/bolts.

6. Two 9/16” wrenches/sockets for 3/8” nuts/bolts.

7. One 2” adjustable wrench for collector ﬁttings.

Stiebel Eltron provides a 30/60° ﬁxed mounting kit (p/n SE60) for

vertical arrangement of collectors. The truss that the kit forms can

be ﬂipped to provide either tilt angle.

5.2.1 30/60° Mounting On A Flat Roof

Two mounting frames are available for ﬁxed 30- and 60-degree

collector tilt:

• R1 for one collector installed vertically (185545). See Figure 14.

• R2 for two collectors installed vertically or one collector

installed horizontally (185546). See Figure 15.

Figure 14: R1 Mounting Frame for Vertical Collector Arrangement

For 30/60° vertical mounting on a ﬂat roof, two sets of (SE60) ﬂat-

roof/wall mounting hardware are needed; for two collectors or

more, the number of sets required is the same as the number of

collectors. See Figure 16.



NOTICE: TO PREVENT EXCESSIVE PRESSURE DROP IN THE SOLAR

LOOP, NEVER LINK UP MORE THAN 5 COLLECTORS IN SERIES.

ARRANGE THE INDIVIDUAL LINEAR ARRAYS PARALLEL TO EACH OTHER.

Building penetrations for plumbing and mounting must not impair

enclosure integrity or functionality and must not allow rodent or

vermin intrusion. They must meet applicable codes and National

Rooﬁng Contractors Assoc. practices. Structural members pen-

etrated by solar system components must not be compromised and

penetrations must meet code, particularly penetrations through ﬁre-

rated construction. Do not reduce ﬁre resistance below code. Protect

control sensor wiring.
