for Vitocrossal 300 and Vertomat boilers

Installation Instructionsfor use by heating contractor

Seismic Restraints Kit

Product Information

The seismic restrainers designed for the Vitocrossal 300 and Vertomat gas-fired condensing boilers work on the principle of combining base-isolation with energy absorbing solid-state devices. The restrainersconsist of two pairs of boomerang shaped metal bars, which are to be installed in corners of the substructurediagonally across from each other.

They are designed to meet the seismic load requirements as specified by the National Building Code of Canada to adopt the “worst case” scenario.

Ensure that main power to the equipment being serviced is off.Ensure that the main fuel supply valve to the boiler is closed.Take precautions to avoid accidental activation of power or fuel during service work.Do not perform service work on any component part without ensuring safe operation of the heating system. When replacing parts, use original Viessmann or Viessmann approved replacement parts.

Refer to the Installation and Start-up/ServiceInstructions applicable to this boiler.

Safety and Installation RequirementsPlease ensure that these instructions are read and understood before starting any service work. Failure to comply with these instructions may cause product/property damage, severe personal injury and/or loss of life.

Working on the equipment

The installation, adjustment, service and maintenance of this product must be performed by a licensed professional heating contractor who is qualified and experienced in the installation, service, and maintenance of hot water boilers.There are no user serviceable parts on the boiler, burner or control.

Assembly Instructions

IMPORTANTCheck the size and quality of the concrete pad, as listed in the attached tables (page 8 and 9), with the builder. The restrainers have to be mounted diagonally on one front and one rear corner of the boiler frame.

1. Decide which sides to use based on the side condition (always diagonal).

Make sure that the bars are mounted before the venting is installed.

2. Take only one existing bolt M12 x 30 out at a time and install the restrainer with the new ½ in. x 2 ¼ in. bolt. There is the possibility that the holes of the frame overlap and the new ½ in. bolt does not fit easily. Use a ½ in. drill bit.

3. Push the front and rear bolts from the inside of the boiler stand to the outside. The side bolts have to have the head of the screw outside because of the restricted space between panel and frame.

Note: For the restrainers for the Vertomat models VSB-05 to VSB-28, washers are needed to close the gap between the upper bracket and the frame d in. (3 mm).

Example of Restrainer Assembly

Example of cut-outs for Vertomat VSB-89

Make sure that all bars are tight to the frame before drilling and mounting the anchor bolts. Each side panel needs a cut-out to allow the bar to pass through the corner of the panel.Depending on the side where the bar is installed, these cut-outs are either measured from the front or from the rear. See illustration for an example of VSB-89 cut-outs. For other sizes, measure the distances accordingly, mark them, and cut with a hex saw.
