1. Disconnect appliance with its appliances main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage heater regulator. 2. Cap off open end of gas pipe where equipment shutoff valve was connected. Install sediment trap in supply line as shown in fig. 7. Place sediment trap where it is within reach for cleaning. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed incorrectly, heater may not run properly. IMPORTANT: hold the pressure regulator with wrench when connecting it to gas piping and/or fittings. Do not over tighten pipe connection to regulator. The regulator body could be damaged. 3. Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas, or using compressed air. 4. Check all joints of gas supply piping system. Apply a non-corrosive leak detection fluid to all joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6. Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks. * A CSA design-certified equipment shutoff valve with 1/8” NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design certified shutoff valve fig. 7 from your dealer. 9 WIR 2 26-06-2003 18:21 Pagina 10 Test pressures equal or less than 1/2 PSIG (3,5 Kpa) 1. Close equipment shutoff valve (see figure 8). 2. Pressurize supply piping system by either opening propane/LP supply tank valve located on or near gas meter for natural gas, or using compressed air. 3. Check all joints from gas meter for natural gas (see figure B) or propane/LP supply tank for propane /LP gas, to equipment shutoff valve (see figure C). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. 4. Correct all leaks at once. PRESSURE TESTING HEATER GAS CONNECTIONS 1. Open equipment shutoff valve (see figure A). 2. For natural gas open main gas valve located on or near gas meter. For propane/LP gas open propane /LP supply tank valve. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from equipment shutoff valve thermostat gas valve (see figure 8/9 or 10). Apply a non-corrosive leak detection fluid to all joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6. Light heater (see operating heater, page 11). Check all other internal joints for leaks. 7. Turn off heater (see to turn off gas to appliance, page 12) 10 Fig.8 Equipment Shutoff Valve Fig.9 Checking Gas Joints for Natural Gas Fig.10 Checking Gas Joints for Propane/LP Gas WIR 2 26-06-2003 18:21 Pagina 11 OPERATING HEATER FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: if you do not not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. Before lighting smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. WHAT TO DO IF YOU SMELL GAS. • Do not try to light any appliance. • Do not touch any electric switch; do not use any phone in your building. • Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier‘ s instruction. • If you cannot reach your gas supplier, call the fire department. C. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don’t try to repair it, call a qualified service technician or gas supplier. Force or attempted repair may result in a fire or explosion. D. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water. LIGHTING INSTRUCTION 1. STOP! Read the safety information above. 2. Make sure equipment shutoff valve is fully open. 3. Turn thermostat control knob clockwise to the OFF position (see fig. 11). 4. Wait five minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow the safety information. If you don’t smell gas, go to the next step. 5. Turn thermostat control knob counterclockwise to the pilot position. Press in thermostat control knob for 5 seconds (see fig. 11). Note: you may be running this heater for the first time after hooking up to gas supply. If so, you may need to press in control knob for 30 seconds or more. This will allow air to bleed from the gas system. • If thermostat control knob does not pop up when released, contact a qualified service person or gas supplier for repairs....
