Follow the appliance manufacturer instructions if available; otherwise, use the instructions provided below.
Do not use a gas control set for natural gas on LP gas or a gas control set for LP gas on natural gas. When making the conversion, the main and pilot burner orifices MUST be changed to meet the specifications of the appliance manufacturer.
Standard or slow-opening gas controls can be converted from one gas to another. Turn off the main gas supply to the appliance. Remove the regulator cap screw and pressure regulator adjusting screw. See Fig. Insert the replacement spring with the tapered end down. Install the new plastic pressure regulator adjustment screw so that the top of the screw is flush level with.
Turn the pressure regulator adjustment screw clockwise six complete turns. This provides a preliminary pressure setting of about Check the regulator setting with a manometer or by clocking the gas meter.
See the Startup and Checkout section. Mount the conversion label on the control. Install the control and the appliance according to the appliance manufacturer instructions. Choose the appropriate flange for your application. Remove the seal over the gas control inlet or outlet. Ensure the O-ring is fitted into the groove of the flange.
If the O-ring is not attached or is missing, do not use the flange. With the O-ring facing the gas control, align the screw holes on the gas control with the holes in the flange. Insert and tighten the screws provided with the flange. Tighten the screws to 25 in. On LP installations, use a compound resistant to LP gas.
Do not use Teflon tape. Apply moderate amount of good quality pipe compound to bushing, leaving two end threads bare. Insert bushing in gas control and thread pipe carefully into bushing until tight. Follow the instructions below for piping, installing control, connecting pilot tubing, thermocouple and wiring.
Make certain 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 flanges are installed, use the wrench only on the flange, not the control. In some field service applications, it is difficult or impossible to thread the gas control onto the gas supply pipe because of space limitations.
This problem can usually be resolved by using an adapter. The adapter is installed on the end of the supply pipe in place of the gas control, following the same precautions and instructions that are used for installing the gas control.
After the adapter is installed, the gas control is attached to the adapter as outlined above. Note that using an adapter increases the overall length of the gas control.
Do not locate the gas control where it can be affected by steam cleaning, high humidity, dripping water, corrosive chemicals, dust or grease accumulation, or excessive heat.
To ensure proper operation, follow these guidelines:. Locate the gas control in the appliance vestibule on the gas manifold. In replacement applications, locate the gas control in the same location as the old gas control. Tubing installation must comply with approved standards and practices.
Use new, properly reamed pipe 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. Run pipe or tubing to the gas control. If tubing is used, obtain a tube-to-pipe coupling to connect the tubing to the gas control. Easy Returns No restocking fee for 90 days.
