C24GA SERIES GAS CONVECTION STEAMERS

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 1½" 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 1 ½" 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 ¼" 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.

GAS SUPPLY CONNECTION

All gas supply connections and any pipe joint

compound used must be resistant to the action

of propane gas. A ¾" 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: ¾" NPT

Natural: 5"

10.5" W.C.

Propane: 11"

13" W.C.

Inadequate gas supply could result in burner

noise and poor burner performance.
