(3.45 KPA). 5. Make certain that new piping, joints and connections have been made in a clean manner and have been purged, so that the piping compound, chips, etc., will not clog valves and/or controls. Use pipe joint sealant that is approved for use with liquefied petroleum gas. 6. WARNING: check all gas connections for leaks, using a soap solution or similar means. Do not check with an open flame. 7. Each thermostat controls one zone burner through a combination dual solenoid/pressure regulator valve, complete with a pressure test spigot. The gas pressure on each combination valve must be checked when the unit is installed to ensure that the gas pressure is the same as specified on the Serial/Rating plate. For access to the pressure test spigots, turn the main power switch to the “OFF” position as a safety precaution, and hinge the lower front panel downwards. Pressure test spigots are located at the rear of each combination valve, including pilot combination valves. When your manometer is connected to the first combination valve for test, turn the manual shut off valve, located under the unit, to the open position (valve handle in line with piping). Turn the main power switch to “ON”. All thermostat dials should be set to approximately 350°F (182°C). When all burners are operating, check the reading on the manometer. If not in accordance with the pressure specified on the Serial/Rating Plate, adjust the combination valve regulator accordingly. When satisfied with manometer reading, turn the main power switch to “OFF”, remove the manometer test tube and recap the test spigot. Repeat this operation on each combination valve until each pressure regulator is set correctly. Turn each thermostat and the main power switch to “OFF. NOTE: Make certain no electrical connections have been disturbed before replacing front panels. Electrical Connection IMPORTANT: This appliance must be electrically grounded in accordance with local codes, or in the absence of local codes, with the Canadian Electrical Code C22.1 (latest edition) or with the National Electrical Code ANSI/NFPA No. 70 (latest edition), whichever is applicable. WARNING: Electrical Grounding Instructions 1. This appliance is equipped with a three prong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three prong receptacle. Do not cut or remove the grounding prong from this plug. 2. A separate 15 amp service must be provided. For 120 volt usage, each unit is electrically equipped with a cord set with a three prong plug which fits any standard 120 volt, three prong grounded receptacle. 3. When the unit is ordered and built for 208/240 volt, the supply line must be connected to the wiring terminations located inside the terminal box. For ease in attaching the supply line, there is a removable cover on the terminal box. A wiring diagram is attached to the rear panel of each unit. Ventilation The unit must be installed in a location in which the facilities for ventilation permit satisfactory combustion of gas and proper venting. Proper ventilation is imperative for good operation of the appliance. The ideal method of ventilating a gas unit is the use of a properly designed ventilating canopy, which should extend at least 6” (152 mm) beyond all sides of the appliance (except against the wall, if the canopy is a wall installation). This is usually part of a mechanical exhaust system. 1. Appliances shall be located so as not to interfere with proper circulation of air within the confined space. All gas burners require sufficient air to operate. 2. Large objects should not be placed in front of the appliance which might obstruct the air flow through the front. Do not obstruct the flow of combustion and ventilation air. 3. Do not permit fans to blow directly at the appliance, and wherever possible, avoid open windows adjacent to the appliance sides and back; also wall type fans which create air crosscurrents within the room. INSTALLATION Continued OPERATION INSTRUCTIONS Lighting Instructions 1. First, make certain that the main power switch is set to “OFF” 2. Connect an electrical power cord to 120 volt supply. 3. Turn the gas shut off valve to the “OPEN” position (valve handle in line with piping). 4. Turn the main power switch to “ON”, power switch green indicator should illuminate. Wait until gas pilot, green indicator illuminates followed by the main burner amber light indicator. NOTE: Should pilot ignition fail after a few minutes turn the main power switch to “OFF”. Wait 5 minutes, then turn the main power switch back to “ON”. 5. When the green indicators for their respective zones are illuminated, set the thermostats to the desired temperature settings. 6. The amber burner indicators cycle with the thermostat operation. Note: During an electrical power interruption, turn power switch to the “OFF” position. This unit cannot be made to operate without electrical power. Shut Down Instructions 1. T...
