Installation (for qualified installers only) 15 Gas Line Requirements MASSACHUSETTS INSTALLATIONS - WARNING: THIS PRODUCT MUST BE INSTALLED BY A LICENSED PLUMBER OR GAS FITTER WHEN INSTALLED WITHIN THE COMMONWEALTH OF MASSACHUSETTS. OTHER MASSACHUSETTS CODE REQUIREMENTS: • Flexible connector must not be longer than 36 inches. • Shutoff valve must be a"T" handle gas cock. • Only direct vent sealed combustion products are approved for bedrooms or bathrooms. • Fireplace dampers must be removed or welded in the open position prior to the installation of a fireplace insert or gas log. A carbon monoxide(CO)detector is required in the same room as the appliance. • The gas line must be installed in accordance with all local codes if any; if not, follow ANSI 223.1 and the requirements listed below. • A manual shutoff valve is required within 3' of the heater. It should be placed upstream of the flex line (if used)and may be installed behind the access door inside the heater. • The heater and gas control valve must be disconnected from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 psig. For pressures under 1/2 psig, isolate the gas supply piping by closing the manual shutoff valve. • Leak test all gas line joints and the gas control valve prior to and after starting the heater. • This heater is designed either for natural gas or propane (but not for both). Check the sticker on the top of the gas control valve to make sure the correct fuel is used (see illustration on page 4). • Installation must be performed by a qualified installer, service agency, or the gas supplier(In Massachusetts a licensed plumber/gas-fitter). Gas Inlet Pressure Gas Pressure Max. Input Pressure Min. Input Pressure Max. Manifold Pressure Min. Manifold Pressure Natural Gas 7"W.C. (1.74 kPA) 5.5"W.C. (1.37 kPA) 3.5"W.C. (0.87 kPA) 1.6"W.C. (0.40 kPA) Propane 13"W.C. (3.23 kPA) 11"W.C. (2.74 kPA) 11"W.C. (2.74 kPA) 2.9"W.C. (0.72 kPA) • If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is adequately adjusted, and the total gas load for the residence does not exceed the amount supplied. • The supply regulator(the regulator that attaches directly to the residence inlet or to the propane tank) should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the regulator is at an improper pressure. Directions for Connecting a Gas Pressure Test Gauge output Pont The gas control valve(shown to the right)has two test ports for testing input(line pressure)and output(manifold)pressure. Loosen the brass screw on either test port cn and place a 5/16"i.d. rubber or plastic tube over the tapered test port. Connect the < { �, tube to the test gauge. WARNING: The brass screw must be tightened after testing to prevent gas leakage. Input Port ©Travis Industries 4/26/2023- 1558 430 MF GSR2
