Resumen del manual
Follow all local codes. Installation Items Needed Before installing heater, make sure you have the items listed below. • piping (check local codes) • sealant (resistant to propane/LP gas) • equipment shutoff valve * • test gauge connection * • sediment trap • tee joint • pipe wrench * An CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known as well-head gas. CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of pressure will occur. Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 13). IMPORTANT:Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves. CAUTION: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas. We recommend that you install a sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. 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 wrong, heater may not run properly. CAUTION: Avoid damage to gas control. Hold gas control with wrench when connecting it to gas piping and/or fittings. CSA/AGA Design-Certified Equipment * Minimum inlet pressure for purpose of input adjustment.

UNVENTED NATURAL GAS LOG HEATER INSTALLATION Continued CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once. Pressure Testing gas Supply Piping system Test Pressures In Excess Of 1/2 PSIG (3.5 kPa) 1. Disconnect appliance with its appliance 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. 3. Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter. 4. Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas 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. Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa) 1. Close equipment shutoff valve (see Figure 14). 2. Pressurize supply piping system by either using compressed air or opening main gas valve located on or near gas meter. 3. Check all joints from gas meter to equipment shutoff valve (see Figure 15). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 4. Correct all leaks at once. Open Equipment Shutoff Closed Valve Figure 14 - Equipment Shutoff Valve Pressure Testing Heater Gas Connections 1. Open equipment shutoff valve (see Figure 14). 2. Open main gas valve located on or near gas meter. 3. Make sure control knob of heater is in the OFF position. 4. Check all joints from equipment shutoff valve to gas control (see Figure 15). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak. 5. Correct all leaks at once. 6. Light heater (see Operating Heater, pages 14 through 16). Check all other internal joints for leaks. 7. Turn off heater (see To Turn Off Gas to Appliance, page 15).
