VR8105, VR8205, AND VR8305 DIRECT IGNITION COMBINATION GAS CONTROLS

Complete the instructions below for installing the piping, installing the control, connecting the pilot gas tubing and the wiring. Make sure the leak test you perform on the control after completing the installation includes leak testing the adapters and screws. If you use a wrench on the valve after the flanges are installed, use the wrench only on the flange, not on the control. See Fig. 5.

Location

The gas controls are mounted in the appliance vestibule on the gas manifold. If this is a replacement application, mount the gas control in the same location as the old control.

Locate the combination gas control where it cannot be affected by steam cleaning, high humidity, or dripping water, corrosive chemicals, dust or grease accumulation or excessive heat. To assure proper operation, follow these guidelines:

•Locate gas control in a well-ventilated area.

•Mount gas control high enough above cabinet bottom to avoid exposure to flooding or splashing water.

•Assure the ambient temperature does not exceed the ambient temperature ratings for each component.

•Cover gas control if appliance is cleaned with water, steam, or chemicals or to avoid dust and grease accumulation.

•Avoid locating gas control where exposure to corrosive chemical fumes or dripping water are likely.

Install Piping to Control

All piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANSI Z223.1, NFPA No. 54), whichever applies. Tubing installation must comply with approved standards and practices.

1.Use new, properly reamed pipe that is free from chips. If tubing is used, make sure the ends are square, deburred and clean. All tubing bends must be smooth and without deformation.

2.Run pipe or tubing to the control. If tubing is used, obtain a tube-to-pipe coupling to connect the tubing to the control.

3.Install a sediment trap in the supply line to the control. See Fig. 3.

Install Control

1.Mounted 0 to 90 degrees in any direction, including vertically, from the upright position of the gas control knob.

2.Mount so the gas flow is in the direction of the arrow on the bottom of the control.

3.Thread the pipe the amount shown in Table 6 for insertion into control or adapters. Do not thread pipe too far. Valve distortion or malfunction can result if the pipe is inserted too deeply.

4.Apply a moderate amount of good quality pipe compound (do not use Teflon tape) only to the pipe, leaving two end threads bare. On LP installations, use a compound resistant to LP gas. See Fig. 4.

5.Remove the seals over the control inlet and outlet if necessary.

6.Connect the pipe to the control inlet and outlet. Use a wrench on the square ends of the control. If a flange is used, place the wrench on the flange rather than on the control. Refer to Figs. 5 and 6.
