GAS Supply Connection

Temperatures in the boiler can briefly reach as high as 212°F (100°C). Local codes require that the temperature of drain water be no greater than 140°F (60°C). At the end of the day, when purging the boilers, some provision for lowering the water temperature must be provided by the user or installer to meet this code requirement.

LOCATION — GAS POWERED STEAMERS & STEAM GENERATORS

The equipment area must be kept free and clear of combustible substances.

The recommended clearance for proper operation is 36" (91.4 cm) at the front. The required clearance from combustible or non-combustible construction is 0" at the sides and back. The recommended clearance for service access is 18" (45.7 cm) at the sides and back.

Do not obstruct the flow of combustion and ventilation air. Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is an adequate supply of air in the room to replace air taken out by the ventilating system. If you have any questions, contact the ventilation system installer.

An exhaust system should be located directly above the steamer to exhaust steam, flue exhaust and heat generated by the steamer.

Do not permit fans to blow directly at the steamer. Avoid wall-type fans which create air crosscurrents within the room.

Avoid open windows next to the steamer.

IMPORTANT: Do not locate the boiler base directly over a drain.

All gas supply connections and any pipe joint compound used must be resistant to the action of propane gases. A 1" (2.5 cm) minimum inside diameter gas supply line is required. If quick-disconnect devices are used, make sure they are rated to meet or exceed the required 270,000 BTU/Hr rate. Make sure the pipes are clean and free of obstructions. Codes require that a gas shutoff valve be installed in the gas line ahead of the steamer.

The burner is equipped with fixed gas and air orifices for use with natural or propane gas.

The gas line must be capable of delivering gas to the boiler without excessive pressure drop at the minimum 270,000 BTU/Hr rate specified on the rating plate. Inadequate gas supply would result in burner noise and poor burner performance. An indication of inadequate supply would be evidenced by a 1/4" W.C. or greater reduction in pilot burner pressure when the main burner comes on.

The boiler is equipped with a factory-preset pressure regulator. Check gas pressures with a manometer at time of installation to verify that they agree with the pressures in the table, below.

GAS SUPPLY PRESSURES

GAS TYPE	Line Pressure		Main Boiler	Pilot Valve
	Minimum	Maximum	Valve Pressure	Pressure

Natural	7.0" W. C.	14.0" W.C.	3.0" W.C.	3.5" W.C.
	(1.75 kPa)	(3.5 kPa)	(0.75 kPa)	(0.88 kPa)

Propane	11.0" W.C.	14.0" W.C.	3.0" W.C.	3.5" W.C.
	(2.7 kPa)	(3.5 kPa)	(0.75 kPa)	(0.88 kPa)

WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS. USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.

After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
