instructions provided with the filter system. At the time of installation you must register your steamer at www.vulcanhart.com/ filterreg or use the reply card supplied with your unit. You will need to register your steamer at each filter change to insure your standard and extended warranty is maintained.

Drain Connection

The 11/2" NPT threaded fitting on the condenser box must be extended a minimum of 12" (305

mm)- maximum of 72" (1829 mm) away from steamer base, to an open air gap type drain. Do not reduce the 11/2" NPT drain piping throughout its length. Provide a suitable floor sink with a minimum depth of 12" (305 mm). The floor sink is NOT to be directly under the steamer and should be at a distance so that steam vapors will not enter the steamer from underneath. The drain should slope down away from the steamer 1/4" for every foot of drain pipe length. The drain pipe should be either iron or copper. DO NOT use PVC pipe; PVC pipe may lose its rigidity or glue may fail.

In order to avoid any back pressure in the steamer, do not connect solidly to any drain connection.

Temperatures in the generator can briefly reach as high as 212°F (l00°C). Local codes may require that the temperature of drain water be no greater than 140°F (60°C). At the end of the day, when purging the generators, some provision for lowering the water temperature must be provided by the user or installer to meet this code requirement.

C24GA SERIES GAS CONVECTION STEAMERS

GAS SUPPLY CONNECTION

All gas supply connections and any pipe joint compound used must be resistant to the action of propane gas. A 3/4" NPT minimum inside diameter gas supply line is required. If quick disconnect devices are used, make sure it is sized properly for data plate BTU/hr. rating. Refer to quick connect supplier’s data sheet.

Codes require that a manual gas shutoff valve be installed in the gas line ahead of the steamer.

The gas line must be capable of delivering gas to the generator without excessive pressure drop at the minimum rate specified on the rating plate.

Check blower air pressure at gas manifold pressure tap by shutting off the gas valve. Air pressure at cold start-up should be 0.35" W.C. (0.09 kPa) (cold condition). After 15 minutes, air pressure should be between 0.40" W.C. (0.1 kPa) and 0.50" W.C. (0.13 kPa) (hot condition). Turn the air pressure adjust screw clockwise to increase pressure and counterclockwise to reduce pressure.

Gas Input:

3/4" NPT

Natural:

5" _ 10.5" W.C.

Propane:

11" _ 13" W.C.

Inadequate gas supply could result in burner noise and poor burner performance.

Refer to the instruction manual supplied with the machine for INSTALLATION CODES AND STANDARDS and GAS CONNECTION information.
