operators, a pressure regulator, pilot adjustment, and a con-

duit cover. See Table 1 for temperature ranges and regulator

types.

BODY PATTERN: Straight-through body pattern.

INLET X OUTLET SIZES AVAILABLE: 1/2 by 3/4 inch

and 3/4 by 3/4 inch.

ADAPTERS: Adapters available for 1/2 and 3/4 inch straight

and angle connections. Refer to Table 2.

Installation To convert a gas control from natural gas to LP gas or from LP gas to natural gas, contact your Honeywell representative. Convert standard- or slow-opening gas controls from one gas to another with a conversion kit (ordered separately). Order part number 393691 to convert from natural to LP gas. Order part number 394588 to convert from LP to natural gas. Step-opening gas controls cannot be converted. WHEN INSTALLING THIS PRODUCT… 1. Read these instructions carefully.

control by following the same precautions and instructions that are used for installing the gas control. After the adapter is installed, attach the gas control to the adapter as outlined above. Note that using an adapter increases the overall length of the gas control. 5. Remove seals over gas control inlet and outlet if necessary. 6. Connect pipe to gas control inlet and outlet. Use wrench on the square ends of the gas control. If an adapter is used, place wrench on adapter rather than gas control.

WHEN FLANGE IS USED WHEN FLANGE IS NOT USED APPLY WRENCH TO FLANGE ONLY APPLY WRENCH FROM TOP OR BOTTOM OF GAS CONTROL TO EITHER SHADED AREA M3083 Connect Pilot Gas Tubing 1. Cut tubing to desired length and bend as necessary for routing to pilot burner. Do not make sharp bends or deform the tubing. Do not bend tubing at gas control or pilot burner after compression fitting has been tightened, because this can result in gas leakage at the connection. 2.

Start-up and Checkout ! ADJUST THE PILOT BURNER FLAME The pilot flame should envelop 3/8 to 1/2 inch [10 to 13 millimeters] of the thermocouple tip. Refer to Fig. 9. To adjust the pilot flame: 1. Remove the pilot adjustment cover screw. Refer to Fig. 5. 2. Turn the inner adjustment screw clockwise to decrease or counterclockwise to increase the pilotflame. 3. Always replace the cover screw after adjustment and tighten firmly to assure proper operation.

Standard-Opening and Slow-Opening Pressure Regulator 1. The gas control outlet pressure should match the manifold pressure listed on the appliance nameplate. 2. With the main burner operating, check the gas control flow rate using the meter clocking method or check the gas pressure using a manometer connected to the gas control outlet pressure tap. Refer to Fig. 4. 3. If necessary, adjust the pressure regulator to match the appliance rating.

Maintenance ! ! Do not apply a jumper across or short the valve coil terminals. This may burn out the heat anticipator in the thermostat. WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Improper cleaning or reassembly may cause gas leakage. When cleaning, assure that control is reassembled properly and perform gas leak test. IMPORTANT: Allow 60 seconds after shutdown before re-energizing step-opening model to assure lightoff at step pressure.

INSTRUCTIONS TO THE HOMEOWNER ! 1. 2. 3. 4. wise WARNING FIRE OR EXPLOSION HAZARD CAN CAUSE PROPERTY DAMAGE, SEVERE INJURY, OR DEATH Follow these warnings exactly: 1. Pilot burner flame must be lit manually. Follow these instructions exactly. 2. Before lighting pilot burner flame, smell around the appliance for gas. Be sure to smell next to floor because LP gas is heavier than air. 3. IF YOU SMELL GAS: • Turn off the gas supply at the appliance service valve.
