IMPORTANT:
Water column (W.C.) pressure of 11.0 inches (27.4 mb) is required at the gas
valve pressure tap of each dryer for proper and safe operation. This will result in
a manifold pressure of 10.5 inches (26.1 mb) water column. The 11.0 inch (27.4
mb) water column pressure
should be
obtained when the gas valve is firing in its
high-fire stage.
WARNING:
Test
ALL
connections for leaks by brushing on a soapy water solution (liquid
detergent also works well.)
WARNING: NEVER TEST FOR GAS
LEAKS WITH A FLAME!!!
ALL
components/materials
must conform
to National Fuel Gas Code Specifications ANSI Z223.1-
LATEST EDITION, or in Canada, CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91
(Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing), as
well as local codes and ordinances and
must be
done by a qualified professional. It is important that gas
pressure regulators meet applicable pressure requirements, and that gas meters be rated for the total
amount of
ALL
the appliance BTUs being supplied.
H. PREPARATION FOR OPERATION
The following items
should be
checked before attempting to operate the dryer:
1. Read and follow
ALL
“CAUTION,” “WARNING,”
and
“DIRECTION”
labels attached to the dryer.
2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label, located on
the rear side of the control door.
NOTE:
208 volts
is not
the same as 230 volts.
3. Check to assure that the dryer is connected to the type of heat/gas indicated on the dryer data label.
4. The sail switch damper assemblies are installed and pre-adjusted at the factory prior to dryer shipment.
However, each sail switch
must be
checked to assure that this important safety control is functioning.
An overly long exhaust duct will increase the back pressure on the dryer and prevent the sail switch from
functioning properly. If this occurs the exhaust duct
must be
shortened.
5. Check bolts, nuts, screws, terminals, and fittings for security.
6. Be sure
ALL
gas shutoff valves are in the open position.
7. Be sure
ALL
back panels and electric box covers have been replaced.
8. Check the upper and lower service doors to assure that they are closed and secured in place.
9. Rotate the baskets (tumblers/drums) by hand to be sure they move freely.
