Requirements for each installation should be fully detailed by a system schematic and specifications.

The assembly and installation instructions described in this manual have been carefully prepared. It is very

important to read these instructions thoroughly before proceeding with the collector installation. An effort has

been made to conform procedures in this manual to the specifications of various governmental and agency

solar programs. Also, many programs allow substitution of manufacturer’s standards for program standards. If

this is the case, the enclosed manual can be used to comply with program standards. Cases where it is unclear

whether the enclosed manufacturer’s standards can be substituted for program standards should be brought to

the attention of the particular program administrator or to Oventrop Corporation for clarification.

Be certain to follow all applicable building and safety codes for installations of solar thermal collectors.

Compliance with local codes is essential. Local code requirements must be met for penetrating structural

members and fire-rating assemblies. Collectors and piping must be installed in such a way that the performance

of any structural member or fire rated assembly is not reduced. Be especially aware of safety regulations when

working upon rooftops. It is the buyer’s responsibility to secure all permits and approvals before purchasing and

attempting the installation of this equipment.

Guidelines and Precautions

Installing Collector Arrays

It is not recommended to install more than four 16-tube collectors in a series (64 tubes). Larger

installations will require parallel piping for balanced flow through each array. Balancing valves should be

installed on multiple arrays. One roof mounting kit is needed for a single collector module. Each additional

collector will require an expansion kit.

Closed Loop and Drainback

OVSOL 5 collectors can be installed for both closed loop and drainback solar heating applications.

Freeze Tolerance Limits

Freeze tolerance limits are based upon the freeze and burst protection of the antifreeze used in the solar

closed loop, or the mixture of the glycol to water ratio. Oventrop NT-40 is a 40% glycol to water mix with

freeze protection to -6oF and burst protection to -40oF. For additional protection, the Regusol 130 EL

control has an antifreeze function “OCF” that can be programmed to enable the circulator to protect the

antifreeze from freezing or thickening.

Shedding Snow

In regions of snow accumulation, collector tilt angles above 50° will shed snow from collectors even after

severe storms. Therefore, in heavy snow areas, it is critical that collectors be sloped to at least a 50° tilt

angle. If collectors are installed on a flat roof in an area that receives heavy snowfall, the lower end of the

units should be at least 18” above the roof level to minimize chances of snow build-up on the bottom of the

evacuated tubes.

Transport of Collector

The collector should be transported to the roof in parts and then assembled together on the rooftop.

Lightning Protection

In areas of high incidence of lightning, one lightning rod should be considered. If there is a ready-made

lightning protection device, please connect it with the collector.

Minimum Inclination Angle of Collector

In order to assure heat pipe delivery, a minimum inclination angle of 25° must be ensured for OV SOL-5

collectors. If the tilt angle of the roof is not above 25°, please build necessary roof mounting racks.

Precautions

Temperatures in excess of 390°F are possible in the condenser (top metal protruding bulb) when exposed

to bright sunlight or diffused insolation. DO NOT TOUCH the condenser. Store the tubes in a safe location

away from the sun during the installation of the roof mounting rack. Tubes are installed as the last step.

Oventrop Corporation will not be liable for burns or personal injury due to the touching of a hot condenser.

Handle the tubes with care to avoid accidental bending of the heat pipe at the condenser which may cause

damage to the heat pipe or the vacuum seal.

The maximum solar loop operating pressure is 87 psi. The pressure relief valve must be set to open below

87 psi. A 75 psi pressure relief valve is suggested. Normal operating pressures for a solar closed loop are

25 to 35 psi.

section two

Collector Layout, Orientation, and Siting

Place the collector where it will receive the maximum amount of sunlight available in your location. OVSOL

collectors may be installed on a roof, against a south facing wall, or on the ground.

Orientation

Orientation and tilt is critical to performance. The OVSOL-5 collectors should be oriented (faced) as close

to true south as practical, although they may be faced as much as 20° east or west of true south with less

than 5% loss in capacity. Because the earth’s magnetic field is not aligned parallel to the earth’s north-

south axis, there are some parts of the United States where the needle of a magnetic compass can point

as much as 20° east or west of true north. There are several ways to determine true south in your area.

You can consult a local surveyor, a plot

map in your local tax office, or a recent

isogonic chart of the United States

published by the U.S. Coast and

Geodetic Survey. Adjust your magnetic

compass reading according to the

meridian nearest to you. Do not use old

charts, as there are annual variations in

the readings. When using a magnetic

compass, beware of standing near large

metallic objects or power lines because

they will affect the compass readings.

Shading

Trees, chimneys, dormers, other buildings, new construction, and even fences may shade the collector

array, especially in the winter when sun angles are low and shadows are long. Be sure the collectors are

placed where they will be not shaded by these obstructions. As a rule, no more than 5% of the collector

area should be shaded between the hours of 9:00 a.m. and 3:00 p.m. It is highly advised to make use of a

solar site selector while determining suitability for a collector site.

Angle of Inclination or Tilt Angle

For domestic water, use an optimum tilt of the site’s latitude plus 5°, although the slope may be 10° greater

or less with a capacity loss of under 5% for the system. For a solar space heating system, a steeper tilt

angle is important for optimal winter performance. The steeper tilt will favor winter system operations when

the sun is low in the sky. Therefore, for space heating systems chose a tilt of latitude plus 15°.

The variation of 10° either way will not seriously affect the total annual performance of the system, all other

things being equal.

The following chart will help you determine the tilt angle of roof pitches. For space heating systems, always

have collectors sloped at optimal tilt for winter performance.

Install a collector rack whenever necessary.

Integrating with Building Architecture

Maintaining a pleasing appearance to the buildings architecture is important for adding solar collectors to a

roof or on the ground. Most homes are not oriented well for solar gain, so getting the collectors at just the

right orientation and tilt may not integrate well with the roof lines.

With domestic hot water systems, there are greater variations to tilt and orientation without large annual

losses, and in some cases may justify flush-mounting collectors. Space heating systems must have a

steep slope and be oriented within 30° of true south. For these larger space heating systems, the layout

should integrate into the roofline. For new construction, integrating OVSOL collectors into the building’s

roof system should be addressed by the solar designer to the architect.

Shedding Snow

A tilt angle of 50° or more is necessary in regions of heavy snowfall and accumulation. Tilt angles of 50°

and above will shed snow from OVSOL- 5 collectors even after severe storms. It is critical in heavy snow

areas that the collectors be sloped to at least a 50° tilt angle. If collectors are installed on a flat roof in an

area which receives heavy snowfalls, the lower end of the units should be at least 18” above the roof level

to minimize chances of snow build-up on the bottom end of the evacuated tubes.

Shading

To avoid shading by collectors on each other, the front to front dimension must be 2.5 times the highest

point of the front collector.

Collector Assembly

Flush Roof Mounting

Measure the Installation Area

Once the collector location is determined, lay out the 4 mounting feet of each collector within the

dimensions listed below:

OVSOL 5 8 tube collector: ‘A’ = 16 to 25 inches; ‘B’ = 63 to 80 inches

OVSOL 5 16 tube collector: ‘A’ = 48 to 66 inches; ‘B’ = 63 to 80 inches

Flush Mounting on Asphalt Shingles

Roof Mounting Kit ORMK-S

Mounting of Collector Feet

Collector feet may be lag bolted into the roof rafters. Since most roof trusses or rafters are built on 16-inch

centers, locate the comers so that the ‘A’ dimension falls on the 16-inch center. To locate the nearest rafters,

use a stud finder. Once the rafter is located, drill a small diameter pilot hole to verify the rafter’s center line.

Be sure to lift the upper shingle and predrill into the underlying (covered) row to prevent water leaks. Lift

shingles carefully to avoid tearing. Always seal pilot holes not being used.

Mark the pilot hole for the center line of the roof rafter or truss. Next, pre-drill two holes for each collector foot

into the center line of the rafter using a drill bit smaller in diameter than the lag bolt supplied. Apply a

generous amount of polyurethane sealant around and within the predrilled hole. Screw the collector feet in

place. Avoid over-tightening and stripping the lag bolts. You may apply a small amount of sealant to the lag

bolt heads to prevent water leakage. The important thing is to locate the collector feet atop roof joists so that

the weight of the collector is supported. Select rafters so that two tubes will overhang to the right and left for

an 8-tube module. For a 16-tube module, you may allow up to four tubes to overhang to the left and right of

the rafters. The overhangs are necessary for better weight distribution.

63” - 80”

If the collector feet are not in line with roof rafters, blocks may be nailed into the joint cavity and the feet

then lag-bolted to the block. Securing collector feet to the roof rafter may also be done by using a span-

ner, using nuts and an all-thread rod to bolt down the feet. An additional wood block between the trusses

must be placed beside the all thread rod to prevent bowing of the sheathing when tightening the nuts in

the all thread rod. Spanners may be required in areas prone to hurricane-force wind.

It is important that in any case the collector feet are bolted to the roof frame.
