J. PREOPERATIONAL TESTS

ALL

dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test

should be

performed before the dryer is publicly used. It is possible that adjustments have changed in transit or

due to marginal location (installation) conditions.

1. Turn on electric power to the dryer.

Open

ALL

shutoff valves (gas models Only).

2. Refer to the Operating Instructions for starting your particular model dryer.

3. Gas Dryers

When a gas dryer is first started (during initial start-up), it has a tendency not to ignite on the first ignition
attempt. This is because the gas supply piping is filled with air, so it may take a few minutes for the air to
be purged from the lines.

NOTE:

During the purging period, check to be sure that

ALL

gas shutoff valves are open.

NOTE:

Gas dryers are equipped with a Direct Spark Ignition (DSI) system, which has internal
diagnostics. If ignition

is

not

established within three (3) attempts, the heat circuit in the DSI

module will “LOCK OUT” until it is manually reset. To reset the DSI system, open and close
the main door and restart the dryer.

A gas pressure test

should be

taken at the gas valve pressure tap of each dryer to ensure that the water

column (W.C.) pressure is correct and consistent.

NOTE:

Water column pressure requirements (measured at the pressure tap of the gas valve body):

Natural Gas .............................. 3.5 inches (8.7 mb) water column.
Liquid Propane (L.P.) Gas ........ 10.5 inches (26.1 mb) water column.

IMPORTANT:

There is no regulator provided in an L.P. dryer. The water column pressure

must be

regulated at the source (L.P. tank), or an external regulator

must be

added to each

dryer.

4. Steam Dryers

Check to ensure that steam damper is functioning properly.

The steam damper should not

“slam” (open or closed) when it reaches the end of (piston) travel. Additionally,

the steam damper should not bind and/or stop during travel. If either of these conditions occur, the flow
control

must be

adjusted. Refer to the

bottom illustration

on

page 30

for steam damper air piston (flow

control) operation adjustment instructions.
