SECTION H: GAS SUPPLY CONNECTIONS

DANGER:

Make sure the gas on which the boiler will operate is the same type as specified on the boiler model and rating plate.

Gas piping must have a sediment trap ahead of the boiler gas controls, and a manual shut-off valve located outside the heater jacket. A pounds to inches regulator must be installed to reduce to gas supply pressure to under 14" W.C. The regulator should be placed a minimum distance of 10 times the pipe diameter upstream of the boiler gas controls. All gas piping must be tested after installation in accordance with local codes. The boiler and its gas connection must be leak-tested before placing it in operation.

GAS SUPPLY CONNECTION

CAUTION:

The boiler and its manual shutoff valve must be disconnected from the gas supply during any pressure testing of the gas supply system at test pressures in excess of 1/2 PSIG (3.45 KPA). The boiler must be isolated from the gas supply piping system by closing the manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG. Relieve test pressure in the gas supply line before reconnecting the boiler and its manual shut off valve to the gas supply line. FAILURE TO FOLLOWTHIS PROCEDURE MAY DAMAGE THE GAS VALVES. Over pressurized gas valves are not covered by warranty. The boiler and its gas connections shall be leak tested before placing the appliance in operation. Use soapy water for leak test: DO NOT use open flame.

CAUTION:

CAUTION:

Do not use Teflon tape on gas line pipe thread. A pipe compound rated for use with gas systems is recommended. Apply sparingly only on male pipe ends.

Support gas supply piping with hangers, not by the boiler or its accessories. Ensure the gas piping is protected from physical damage and freezing where required.

GAS SUPPLY PRESSURE

A minimum of 7” W.C. and a maximum of 14” W.C. upstream gas pressure is required under load and no load conditions for natural gas. A minimum of 12” W.C. and a maximum of 14” W.C. is required for propane gas. The gas pressure regulator supplied on the boiler is for low pressure service. If upstream pressure exceeds 14" W.C, an intermediate gas pressure regulator, of the lockup type, must be installed.

When connecting additional gas utilization equipment to the gas piping system, the existing piping must be checked to determine if it has adequate capacity.
