Clearances to combustibles are posted on the control box. In areas used for storage of combustible materials where they may be stacked below the heater, NFPA54 requires that the installer must post signs that will “specify the maximum permissible stacking height to maintain the required clearances from the heater to combustibles.” Space-Ray recommends posting these signs adjacent to the heater thermostat or other suitable location that will provide enhanced visibility. Form #43155010 Feb-04 -11- 20) GAS CONNECTIONS AND REGULATIONS 1. Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation is made. (In Canada, refer to the latest edition of CAN Standard B.149-1 & -2, Installation Codes for Gas Burning Appliances and Equipment.) 2. All gas supply lines must be located in accordance with the required clearances to combustibles below the heater as listed on the nameplate of the heater. 3. Pipe joint compounds must be resistant to the action of liquefied petroleum gases. 4. Straight tube heaters (LTS series) can expand/contract during operation. If rigid pipe connections are planned, provisions for expansion/contraction must be provided. Where local codes do not prohibit, a CSA or U.L. approved flexible connector (minimum 5/8" I.D.) is recommended between the rigid piping and the heater. A union and an approved shut off valve should be installed before the control valve inlet. The shut off valve should be installed within 6 feet of the union. 5. This appliance is equipped with a step-opening, combination gas valve. The maximum supply pressure to the appliance Is 14” W.C. or 1/2 P.S.I. If the line pressure is more than the maximum supply pressure, then a second stage regulator which corresponds to the supply pressure must be used. 6. If a 2nd stage regulator is used and gas seeps through it, the redundant combination gas valve is designed to lock out. Pressure build-up in the supply lines prior to the heater must be released before proper heater operation. 7. After all gas connections have been made, make sure the heater and all gas outlets are turned off before the main gas supply is turned on. Turn the gas pressure on and check for leaks. To check for leaks, apply a soap suds solution to all connections and joints or check by one of the methods listed In Appendix D of the National Fuel Gas Code. ! DO NOT USE AN OPEN FLAME OF ANY KIND TO TEST FOR LEAKS. * Manual Gas Shut Off Valve * Available as Accessories SIDE VIEW 21) INSTRUCTIONS FOR PRESSURE TEST GAUGE CONNECTION_ ♦ Supply Pressure 1. The installer will provide a 1/S” N.P.T. plugged tapping, accessible for test gauge connection immediately upstream of the gas supply connection to the heater. ♦ Manifold Pressure 1. Turn the gas valve to the “OFF" position. Remove the 1/8" plug from the combination gas valve at the ou...
