NOTE: The Model No. KFHP Series Hot Plates are not ETL Certified Designs. INSTALLATION THIS APPLIANCE IS INTENDED FOR OTHER THAN HOUSEHOLD USE All FHP Series, STFHP Series, and KFHP Series Hot Plates are for use in combustible and non-combustible locations when installed on a non-combustible counter. All Comstock-Castle commerical gas appliances are manufactured by skilled craftsman using the finest quality materials.
If a regulator has been shipped with the unit, it MUST be installed properly. If not factory installed, connect regulator with arrow pointing in the direction of gas flow. Use thread compound sparingly. NOTE: DO NOT APPLY thread compound to the female threads of any part. HOOK-UP PROCEDURE FOR COMBINATION UNITS: Units prefixed with a “2” may be shipped separately. For connection, set the units side by side. Install backsplash. Install hook-up strip in the front center of the two units.
TO LIGHT THE CHINA HAT PILOTS: (OPEN TOP BURNERS) 2. Blow out pilot. The safety valve will automatically shut off the gas supply system. 1. The main gas valve should be “OFF” for at least five minutes to allow any accumulated gas to escape the combustion chamber. TO LIGHT A STANDING PILOT: (Manually Controlled Griddles) 2. Remove spider rings, open top grates, and locate the pilots. 3. Turn supply gas “ON” and hold match close to the pilot head. The pilot should light. 1.
6. ALWAYS ensure the cap is replaced on the regulator. DIMENSIONS 7. Turn the gas and the unit “OFF” and reinstall the pressure tap test plug. 8. Ensure the top of the regulator is kept clear of dust and fluids as these will clog the regulator vent port. Figure 3 Robertshaw Grayson TS11J Safety Valve APPLICATION The H43 valve is designed to provide safe lighting and complete shutoff of pilot and main burner gas.
STANDING & CHINA HAT PILOT ADJUSTMENT PROCEDURE: (Fig. 5) 1. Ensure the unit is shut off and cooled down. 2. Remove all knobs and the front apron panel from the unit. NOTE: Caution must be exercised during the initial installation and/or conversion of standing or china hat pilots to ensure that the pilot valves are not wide open. 3. Loosen screw on the air mixer which is located on the venturi section of the burner. 1.
THERMOSTAT CALIBRATION: (See Fig. 6) 6. While firmly holding the calibration stem in, turn the dial to the actual temperature shown on the test instrument. Release the pressure on the calibration stem and remove the screwdriver. Replace the dial insert. NOTE: Once the appliance is properly installed, all thermostats associated with the equipment must be checked for proper calibration. The thermostat is a precision instrument and is carefully calibrated at the factory.
TROUBLESHOOTING THE MANUAL PILOT SYSTEM PROBLEM: (Pilot will not stay lit.) 1. Place the sensing probe of the test instrument in the middle of the oven. 2. Light main burner and set the temperature dial to 400 degrees. Allow the oven to heat until the burner flame cuts down to bypass. Check temperature on the test instrument. If temperature does not read within 10 degrees of the dial setting, recalibrate as follows: 1. Check for drafts that could blow out the pilots. 2.
Main gas NPT connections (inlet or outlet) e. Use joint compound/thread sealant, properly threaded pipes and careful assembly procedure so that there is no cross threading, etc., which can cause damage or leakage. f. Apply light pressure only at wrench flats (see Figure 1) to avoid damage to control body, which can result in leakage or malfunction of control. Do not apply pressure to top casting or plastic cover. 4.
( *Do not rotate side outlet in its threads to avoid possible leakage.) i. Replace cover. 7. V ery high pressure surges in the gas supply line (or as a result of exposing the system to high pressure) may result in serious internal damage and cause leakage or affect control operation. If you suspect tht a Mertik Maxitrol control has been exposed to more than 1-1/2 times its maximum inlet pressure, turn off the gas and have the system checked by an expert.
! 4. Light burners. Adjust the flame to the lowest setting possible. Maintain a low flame setting for one hour. WARNING USE CAUTION WHEN LEAVING AN OPERATING 5. Allow the plate to cool, then wipe off residue with a clean cloth. MOTORIZED CONTROL UNATTENDED.
There are many other factors to keep in mind, more so in a mobile operation. Many people think they do not need a pressure regulator on the appliance as well as on the tank. This is not true! There should always be a tank regulator on the tank and an appliance regulator on each gas appliance due to each appliance’s distinctive operation pressure. Giving an appliance too much or too little gas pressure can cause operation and performance problems.
problems and when the pilot goes out, The entire unit shuts down and must be relit. Never place anything on top of the flue!! the 2923SF, 2932SF, 2941SF is designed to operate with the front door in place. The front door is removeable for cleaning, servicing and draining, but should be kept on during operation. TO CLEAN THE OVEN/BROILER INTERIOR: 1. Allow the oven/broiler interior to cool, completely. Use a nonalkaline based cleaning agent, following the recommendations of the manufacturer.
TROUBLESHOOTING CHART PROBLEM PROBABLE CAUSE POSSIBLE SOLUTION 1. Appliance will not ignite. 1a. No gas. 1b. Air in gas line. 1c. Improper gas line supply. 1d. Gas turned on too fast at tank. 1a. Ensure gas is turned on. 1b. Purge air from gas line. 1c. Ensure piping will supply adequate pressure. 1d. Turn on at tank very slowly. 2. Pilots will not light. 2a. Pilot valve is shut off. 2b. Fans or air drafts interfering with pilot operation. 2c. Improper pilot adustment. 2d. Bad or weak thermocouple.
